We employ multibillion time step embedded-atom molecular dynamics simulations to investigate the homoepitaxial growth of Pt(111) from hyperthermal Pt atoms (EPt=0.2–50eV) using deposition fluxes approaching experimental conditions. Calculated antiphase diffraction intensity oscillations, based on adatom coverages as a function of time, reveal a transition from a three-dimensional multilayer growth mode with EPt<20eV to a layer-by-layer growth with EPt≥20eV. We isolate the effects of irradiation-induced processes and thermally activated mass transport during deposition in order to identify the mechanisms responsible for promoting layer-by-layer growth. Direct evidence is provided to show that the observed transition in growth modes is primarily due to irradiation-induced processes which occur during the 10ps following the arrival of each hyperthermal atom. The kinetic pathways leading to the transition involve both enhanced intralayer and interlayer adatom transport, direct incorporation of energetic atoms into clusters, and cluster disruption leading to increased terrace supersaturation.
Embedded-atom molecular dynamics simulations were used to investigate the effects of low-energy (5–50 eV) normally-incident self-ion irradiation of two-dimensional compact Pt3, Pt7, Pt19, and Pt37 clusters on Pt(111). We follow atomistic pathways leading to bombardment-induced intra- and interlayer mass transport. The results can be described in terms of three impact energy regimes. With E ≤ 20 eV, we observe an increase in 2D island dimensions and negligible residual point defect formation. As the impact energy is raised above 20 eV, we observe an increase in irradiation-induced lateral mass transport, a decrease in island size, and the activation of interlayer processes. For E ≥ 35 eV, this trend continues, but point defects, in the form of surface vacancies, are also formed. The results illustrate the richness of the dynamical interaction mechanisms occurring among incident energetic species, target clusters, and substrate atoms, leading to island preservation, reconfiguration, disruption and/or residual point defects formation. We discuss the significance of these results in terms of thin film growth.
Embedded-atom molecular dynamics simulations are used to investigate the effects of low-energy self-ion irradiation of Pt adatoms on Pt(111). Here, we concentrate on self-bombardment dynamics, i.e., isolating and monitoring the atomic processes, induced by normally incident Pt atoms with energies E ranging from 5 to 50 eV, that can affect intra- and interlayer mass transport.. We find that adatom scattering, surface channeling, and dimer formation occur at all energies. Atomic intermixing events involving incident and terrace atoms are observed at energies 15 eV, while the collateral formation of residual surface vacancies is observed only with E>40 eV. The overall effect of low-energy self-ion irradiation is to enhance lateral adatom and terrace atom migration. ©2005 American Institute of Physics
The effects of substitutional additives on the properties and phase stability of - and -alumina (Al2O3), are investigated by density functional theory total energy calculations. The dopants explored are 5 at. % of Cr, Mo, Co, and As substituting for Al, respectively, N and S substituting for O, in the and lattices. Overall, the results show that it is possible to shift, and even reverse, the relative stability between - and -alumina by substitutional additives. The alumina bulk moduli are, in general, only slightly affected by the dopants but density of states profiles reveal additional peaks in the alumina band gaps. We also show that phase separations into pure oxides are energetically favored over doped alumina formation, and we present results on a number of previously unstudied binary oxides.
In this work we report the investigation of defect generation in Mo/W superlattices (SL). The study has been carried out using molecular dynamics (MD) and the embedded atom (EAM) potential. Mechanisms for the generation of observed defect patterns are proposed.
We report here the results of a Molecular Dynamics-Embedded Atom Method-investigation of the pathways generating point defects in Mo/W superlattices during bombardment with energetic (50 to 200 eV) Ar and Kr neutrals. Energy accommodation coefficients are computed for the different structures and are found to be roughly independent of the incident energy, and substantially higher for structures with Mo on top. Several different types of defects are shown, and two general processes generating those are discussed. Trapping of the incoming noble gas was observed for the case of Kr impinging on structures with Mo as the top monolayer; this is interpreted as an effect of the small mass difference between the Mo and the Kr atoms. An increase in atomic mass of the gas translates into a more disparate behaviour of the studied structures. The energy exchange with the surface layer dictates the behaviour of the superlattice; this is accentuated when bombarding with the heavier gas, Kr. (C) 1998 Elsevier Science S.A.
An investigation of defect generation at the interface during growth of epitaxial (100) oriented Mo/W superlattices by ion-assisted deposition has been carried out using molecular-dynamics simulations. The influence of the impact parameter within the irreducible bcc unit cell [001] surface and the incident ion energy on the energy accommodation, the dynamics of energy transfer, and energy dissipation are discussed. A detailed model of the generation of point defects is presented and the influence of materials upon the type and the number of defects as well as the energy accommodation of the superlattice is revealed. It is shown that the behavior of the superlattice as a whole is largely dominated by the material in the surface monolayer.
Embedded-atom molecular dynamics simulations were used to follow the diffusion dynamics of compact Pt clusters with up to 19 atoms on Pt (111) surfaces. The results reveal a novel cluster diffusion mechanism, involving successive shear translations of adjacent subcluster regions, which give rise to reptation, a snake-like gliding motion. We show that for compact clusters with 4 to 6 atoms, this mechanism competes energetically with that of island diffusion through concerted motion. However, as the cluster size increases from > 7 to ? 20 atoms, reptation becomes the energetically favored diffusion mechanism. The concerted shear motion of subcluster regions, leading to reptation, is also shown to play a significant role in dendritic-to-compact morphological transitions of Pt island.
Embedded-atom molecular-dynamics simulations were used to follow the diffusion dynamics of compact platinum clusters with up to 19 atoms on Pt(lll). The results reveal a cluster diffusion mechanism on (111) face-centered-cubic (fcc) surfaces involving successive shear translations of adjacent subcluster regions giving rise to reptation, a snake-like gliding motion. We show that for compact clusters with <7 atoms, this mechanism competes energetically with that of island diffusion through concerted motion. However, for cluster sizes of between 8 and similar or equal to 20 atoms, reptation becomes energetically favorable, especially for elongated clusters. Reptation is also shown to be an important migration mechanism for fractal (randomly ramified) and dendritic (symmetrically branched) islands. (C) 1999 Elsevier Science B.V. All rights reserved.
We use molecular dynamics simulations to follow the dynamics of small two-dimensional Pt clusters on Pt(111) at 1000 K. While close-packed Pt-7 heptamers are extremely stable structures, the addition of a single cluster vacancy or an on-top adatom immediately results in intracluster bond breaking, reconfigurations, rotations, the introduction of stacking faults, and greatly enhanced cluster diffusion rates. Mapping center-of-mass motion for total simulation times >145 ns revealed increases in cluster velocities by more than an order of magnitude with cluster migration occurring primarily by concerted motion and a novel diffusion mechanism involving double shearing of dimers/trimers. Contrary to some previous reports, edge-atom diffusion plays only a minor role. (C) 1998 American Institute of Physics.
Improved toughness is one of the central goals in the development of wear-resistant coatings. Previous studies of toughness in transition metal nitride alloys have addressed the effects of chemical composition in these compounds. Herein, we use density functional theory to study the effects of various metal sublattice configurations, ranging from fully ordered to fully disordered, on the mechanical properties of VM2N and TiM2N (M2 = W, Mo) ternary alloys. Results show that all alloys display high incompressibility, indicating strong M-N bonds. Disordered atomic arrangements yield lower values of bulk moduli and C11 elastic constants, as well as higher values of C44 elastic constants, compared to ordered structures. We attribute the low C44 values of ordered structures to the formation of fully-bonding states perpendicular to the applied stress. We find that the ductility of these compounds is primarily an effect of the increased valence electron concentration induced upon alloying.
We use classical molecular dynamics and the modified embedded atom method to determine residence times and descent pathways of Ti and N adatoms on square, single-atom-high, TiN islands on TiN(001). Simulations are carried out at 1000 K, which is within the optimal range for TiN(001) epitaxial growth. Results show that the frequency of descent events, and overall adatom residence times, depend strongly on both the TiN(001) diffusion barrier for each species as well as the adatom island-edge location immediately prior to descent. Ti adatoms, with a low diffusion barrier, rapidly move toward the island periphery, via funneling, where they diffuse along upper island edges. The primary descent mechanism for Ti adatoms is via push-out/exchange with Ti island-edge atoms, a process in which the adatom replaces an island edge atom by moving down while pushing the edge atom out onto the terrace to occupy an epitaxial position along the island edge. Double push-out events are also observed for Ti adatoms descending at N corner positions. N adatoms, with a considerably higher diffusion barrier on TiN(001), require much longer times to reach island edges and, consequently, have significantly longer residence times. N adatoms are found to descend onto the terrace by direct hopping over island edges and corner atoms, as well as by concerted push-out/exchange with N atoms adjacent to Ti corners. For both adspecies, we also observe several complex adatom/island interactions, before and after descent onto the terrace, including two instances of Ti islandatom ascent onto the island surface.
It has been shown both experimentally and by density functional theory calculations that the primary diffusing species during the epitaxial growth of TiN/TiN(001) are Ti and N adatoms together with TiNx complexes (x = 1, 2, 3), in which the dominant N-containing admolecule species depends upon the incident N/Ti flux ratio. Here, we employ classical molecular dynamics (CMD) simulations to probe the dynamics of TiNx (x = 1–3) admolecules on 8 × 8 atom square, single-atom-high TiN islands on TiN(001), as well as pathways for descent over island edges. The simulations are carried out at 1000 K, a reasonable epitaxial growth temperature. We find that despite their lower mobility on infinite TiN(001) terraces, both TiN and TiN2 admolecules funnel toward descending steps and are incorporated into island edges more rapidly than Ti adatoms. On islands, TiN diffuses primarily via concerted translations, but rotation is the preferred diffusion mechanism on infinite terraces. TiN2 migration is initiated primarily by rotation about one of the N admolecule atoms anchored at an epitaxial site. TiN admolecules descend from islands by direct hopping over edges and by edge exchange reactions, while TiN2 trimers descend exclusively by hopping. In contrast, TiN3 admolecules are essentially stationary and serve as initiators for local island growth. Ti adatoms are the fastest diffusing species on infinite TiN(001) terraces, but on small TiN/TiN(001) islands, TiN dimers provide more efficient mass transport. The overall results reveal the effect of the N/Ti precursor flux ratio on TiN(001) surface morphological evolution and growth modes.
Large-scale classical molecular dynamics simulations of epitaxial TiN/TiN(001) thin film growth at 1200K are carried out using incident flux ratios N/Ti -1, 2, and 4. The films are analyzed as a function of composition, island size distribution, island edge orientation, and vacancy formation. Results show that N/Ti-1 films are globally understoichiometric with dispersed Ti-rich surface regions which serve as traps to nucleate 111-oriented islands, leading to local epitaxial breakdown. Films grown with N/Ti=2 are approximately stoichiometric and the growth mode is closer to layer-by-layer, while N/Ti-4 films are stoichiometric with N-rich surfaces. As N/Ti is increased from 1 to 4, island edges are increasingly polar, i. e., 110-oriented, and N-terminated to accommodate the excess N flux, some of which is lost by reflection of incident N atoms. N vacancies are produced in the surface layer during film deposition with N/Ti-1 due to the formation and subsequent desorption of N-2 molecules composed of a N adatom and a N surface atom, as well as itinerant Ti adatoms pulling up N surface atoms. The N vacancy concentration is significantly reduced as N/Ti is increased to 2; with N/Ti-4, Ti vacancies dominate. Overall, our results show that an insufficient N/Ti ratio leads to surface roughening via nucleation of small dispersed 111 islands, whereas high N/Ti ratios result in surface roughening due to more rapid upper-layer nucleation and mound formation. The growth mode of N/Ti-2 films, which have smoother surfaces, is closer to layer-by-layer. (C) 2016 American Vacuum Society.
The authors report the growth and mechanical properties of epitaxial B1 NaCl-structure V1-xWxN/MgO(001) thin films with 0 ≤ x ≤ 0.60. The Gibbs free energy of mixing, calculated using density functional theory (DFT), reveals that cubic V1-xWxN solid solutions with 0 ≤ x ≤ 0.7 are stable against spinodal decomposition and separation into the equilibrium cubic-VN and hexagonal-WN binary phases. The authors show experimentally that alloying VN with WN leads to a monotonic increase in relaxed lattice parameters, enhanced nanoindentation hardnesses, and reduced elastic moduli. Calculated V1-xWxN lattice parameters and elastic moduli (obtained from calculated C11, C12, and C44 elastic constants) are in good agreement with experimental results. The observed increase in alloy hardness, with a corresponding decrease in the elastic modulus at higher x values, combined with DFT-calculated decreases in shear to bulk moduli ratios, and increased Cauchy pressures (C12–C44) with increasing x reveal a trend toward increased toughness.
Using a combination of experiments and density functional theory (DFT), we demonstrate the first example of vacancy-induced toughening, in this case for epitaxial pseudobinary NaCl-structure substoichiometric V0.5Mo0.5Nx alloys, with N concentrations 0.55 ≤ x ≤ 1.03, grown by reactive magnetron sputter deposition. The nanoindentation hardness H(x) increases with increasing vacancy concentration from 17 GPa with x = 1.03 to 26 GPa with x = 0.55, while the elastic modulus E(x) remains essentially constant at 370 GPa. Scanning electron micrographs of indented regions show ductile plastic flow giving rise to material pile-up, rather than cracks as commonly observed for hard, but brittle, transition-metal nitrides. The increase in alloy hardness with an elastic modulus which remains constant with decreasing x, combined with the observed material pile-up around nanoindents, DFT-calculated decrease in shear to bulk moduli ratios, and increased Cauchy pressures (C12-C44), reveals a trend toward vacancy-induced toughening. Moreover, DFT crystal orbital overlap population analyses are consistent with the above results.
Hardness is an essential property for a wide range of applications. However, hardness alone, typically accompanied by brittleness, is not sufficient to prevent failure in ceramic films exposed to high stresses. Using VN as a model system, we demonstrate with experiment and density functional theory (DFT) that refractory VMoN alloys exhibit not only enhanced hardness, but dramatically increased ductility. V0.5Mo0.5N hardness is 25% higher than that of VN. In addition, while nanoindented VN, as well as TiN reference samples, suffer from severe cracking typical of brittle ceramics, V0.5Mo0.5N films do not crack. Instead, they exhibit material pile-up around nanoindents, characteristic of plastic flow in ductile materials. Moreover, the wear resistance of V0.5Mo0.5N is considerably higher than that of VN. DFT results show that tuning the occupancy of d-t2g metallic bonding states in VMoN facilitates dislocation glide, and hence enhances toughness, via the formation of stronger metal/metal bonds along the slip direction and weaker metal/N bonds across the slip plane.
A study was performed on quantum design and synthesis of a boron-oxygen-yttrium (BOY) phase. The calculations predicted that the BOY phase was 0.36 eV/atom more stable than crystalline BO0.17. The results showed that films with Y/B ratios ranging from 0.10 to 0.32, as determined via elastic recoil detection analysis, were grown over wide range of temperatures (300-600°C) and found to withstand 1000°C.
The effect of chemical composition on the elastic and electrical properties is studied for the BOxYz system with 0.27less than or equal toxless than or equal to1.14 and 0.36less than or equal tozless than or equal to0.08. We use ab initio calculations to obtain the elastic constants and density of states for BO1.5 and the BOY phase (yttrium substituting for oxygen in the boron suboxide structure). For decreasing x values, the elastic modulus is predicted to increase from 11 to 340 GPa, while electronic structure calculations suggest a shift in electrical properties from insulating to metallic. Thin films in the B-O-Y system are grown by reactive rf magnetron sputtering. As x decreases from 1.14 to 0.27, the elastic modulus increases from 12 to 282 GPa, which is a factor of 24, while resistivity decreases from 7.6+/-0.4 to (3.8+/-0.1)x10(-2) Omegam. The observed shifts in elasticity and resistivity are shown to be induced by the associated changes in chemical bonding from van der Waals type in BO1.5 to icosahedral type in the BOY phase.
Elastic modulus of amorphous boron suboxide thin films was studied by theoretical and experimental methods. It was shown that the increase of x in the a-BOx films from 0.08 to 0.18 decreased the magnitude of the elastic modulus from 273 to 231 GPa. The decrease of the elastic modulus with an increasing amount of O was correlated to the presence of the long B-O bonds with ionic contribution and the reduction of the film density.
Molecular dynamics simulations were used to follow the dynamics of the motion of hexagonal Pt heptamers on Pt(111). Close packed Pt-7 clusters on fee sites were found to be very stable structures with reconfiguration or translation events occurring only rarely over simulation times >30 ns at 1000 K. The adsorption of a single adatom on the cluster surface, however, induced rapid intracluster bond breaking, reconfiguration, the introduction of stacking faults, and greatly enhanced cluster diffusion rates. Cluster migration occurred primarily through sequences of individual atom and concerted dimer jumps, but concerted cluster motion was also observed. The adatoms eventually descended to the terrace, predominantly through push-out/exchange reactions with cluster atoms at B edges.
We use embedded-atom molecular dynamics simulations to follow the dynamics of adatoms, vacancies, and adatom/vacancy pairs on two-dimensional hexagonal Pt19 clusters on Pt(1 1 1) surfaces at 1000 K. All configurations are found to be quite stable and have essentially the same migration mobilities as compact hexagonal clusters. However, the presence of a single vacancy dramatically decreases the lifetime of an adatom on the cluster by a factor of three. This occurs primarily through an enhancement of the rate of push-out/exchange reactions at the outer cluster edge resulting from vacancy-induced softening of edge atom bonds. Overall, adatoms in the presence of vacancies descend to the terrace via vacancy filling 10% of the time, and through reactions with outer cluster edges the remaining 90%. Direct vacancy filling mechanisms are analogous to, and have similar activation energies with, those at outer cluster edges: adatom hopping over descending steps and push-out/exchange reactions. © 2003 Elsevier B.V.

Cluster migration is known to be an important process during film growth at elevated temperatures, but relatively little quantitative data is available. We have used molecular dynamics simulations to follow the dynamics of small two-dimensional Pt clusters on Pt(lll) at 1000 K. While close-packed Pt-7 heptamers are extremely stable structures, the addition of a single-cluster vacancy or an on-top adatom immediately results in intracluster bond breaking, reconfigurations, rotations, the introduction of stacking faults, and greatly enhanced cluster-diffusion rates. Mapping center-of-mass motion for total simulation times > 145 ns revealed increases in cluster velocities by more than an order of magnitude with cluster migration occurring primarily by concerted motion and a novel diffusion mechanism involving double shearing of dimers/trimers. Contrary to some previous reports, edge-atom diffusion plays only a minor role. (C) 1998 Elsevier Science S.A.
A combinatorial method was employed to grow TiAlN-WNx films by DC sputtering as well as by High Power Pulsed Magnetron Sputtering (HPPMS) where the W concentration was varied between 10-52 at.% and 7-54 at.%, respectively. Experiments were paired with ab initio calculations to investigate the correlation between composition, structure, and mechanical properties. During all depositions the time averaged power was kept constant. As the W concentration was increased, the lattice parameter of cubic TiAlN-WNx films first increased and then decreased for W concentrations above approximate to 29 at.% (DCMS) and approximate to 27 at.% (HPPMS) as the N concentration decreased. Calculations helped to attribute the increase to the substitution of Ti and Al by W and the decrease to the presence of N vacancies. Youngs modulus and hardness were around 385-400 GPa and 29-31 GPa for DCMS and 430-480 GPa and 34-38 GPa for HPPMS, respectively, showing no significant trend as the W concentration was increased, whereas calculations showed a continuous decrease in Youngs modulus from 440 to 325 GPa as the W concentration was increased from 0 to 37.5 at.%. The presence of N vacancies was shown to increase the calculated Youngs modulus. Hence, the relatively constant values measured may be understood based on N vacancy formation as the W concentration was increased. HPPMS-deposited films exceed DCMS films in Youngs modulus and hardness, which may be a consequence of the larger degree of ionization in the HPPMS plasma. It is reasonable to assume that especially the ionized film forming species may contribute towards film densification and N vacancy formation.
Improved toughness in hard and superhard thin films is a primary requirement for present day ceramic hard coatings, known to be prone to brittle failure during in-use conditions. We use density functional theory calculations to investigate a number of (TiAl)(1-x)MxN thin films in the B1 structure, with 0.06 andlt;= x andlt;= 0.75 obtained by alloying TiAlN with M = V, Nb, Ta, Mo and W. Results show significant ductility enhancements, hence increased toughness, in these compounds. Importantly, these thin films are also predicted to be superhard, with similar or increased hardness values, compared to Ti0.5Al0.5 N. For (TiAl)(1-x)WxN the results are experimentally confirmed. The ductility increase originates in the enhanced occupancy of d-t(2g) metallic states, induced by the valence electrons of substitutional elements (V, Nb, Ta, Mo, W). This effect is more pronounced with increasing valence electron concentration, and, upon shearing, leads to the formation of a layered electronic structure in the compound material, consisting of alternating layers of high and low charge density in the metallic sublattice, which in turn, allows a selective response to normal and shear stresses.
We use classical molecular dynamics and the modified embedded atom method formalism to investigate the dynamics of atomic-scale transport on a low-index model compound surface, TiN(001). Our simulations, totaling 0.25 mu s for each case study, follow the pathways and migration kinetics of Ti and N adatoms, as well as TiNx complexes with x = 1-3, which are known to contribute to the growth of TiN thin films by reactive deposition from Ti, N-2, and N precursors. The simulations are carried out at 1000 K, within the optimal range for TiN(001) epitaxial growth. We find Ti adatoms to be the highest-mobility species on TiN(001), with the primary migration path involving jumps of one nearest-neighbor distance d(NN) between adjacent fourfold hollow sites along in-plane andlt; 100 andgt; channels. Long jumps, 2d(NN), are also observed, but at much lower frequency. N adatoms, which exhibit significantly lower migration rates than Ti, diffuse along in-plane andlt; 110 andgt; directions and, when they intersect other N atoms, associatively form N-2 molecules, which desorb at kinetic rates. As expected, TiN and TiN3 complexes migrate at even lower rates with complex diffusion pathways involving rotations, translations, and rototranslations. TiN2 trimers, however, are shown to have surprisingly high diffusion rates, above that of N adatoms and almost half that of Ti adatoms. TiN3 motion is dominated by in-place rotation with negligible diffusion.
Ab initio molecular dynamics simulations based on density functional theory show that N adatoms are chemisorbed in threefold sites close to a N surface atom and between the two diagonally opposed neighboring Ti surface atoms on TiN(001). The most probable N adatom reaction pathway, even in the presence of nearby N adatoms, is for the N adatom and N surface atom pair to first undergo several exchange reactions and then desorb as a N2 molecule, resulting in a surface anion vacancy, with an activation barrier Edes of 1.37 eV and an attempt frequency Ades = 3.4 × 1013 s− 1. Edes is essentially equal to the N adatom surface diffusion barrier, Es = 1.39 eV, while As is only three to four times larger than Ades, indicating that isolated N adatoms migrate for only short distances prior to N2 desorption. The probability of N2 desorption via recombination of N adatoms on TiN(001) is much lower due to repulsive adatom/adatom interactions at separations less than ~ 3 Å which rapidly increase to ~ 2 eV at a separation of 1.5 Å. We obtain good qualitative and quantitative agreement with the above results using the modified embedded atom method potential to perform classical molecular dynamics simulations.
Ab initio and classical molecular dynamics (AIMD and CMD) simulations reveal that Ti adatoms on TiN(001) surfaces migrate between neighboring fourfold hollow sites primarily along in-plane less than100greater than channels. less than100greater than and less than110greater than single jumps, as well as less than100greater than double jump rates, obtained directly from MD runs as a function of temperature, are used to determine diffusion activation energies Ea, and attempt frequencies A, for the three preferred Ti adatom migration pathways on TiN(001). From transition rates Aexp[-Ea / (k(B)T)], we determine adatom surface distribution probabilities as a function of time, which are used to calculate adatom diffusion coefficients D(T). AIMD and CMD predictions are consistent and complementary. Using CMD, we investigate the effect on the adatom jump rate of varying the phonon wavelength degrees of freedom by progressively increasing the supercell size. We find that long-wavelength phonons significantly contribute to increasing adatom mobilities at temperatures less than= 600 K, but not at higher temperatures. Finally, by directly tracking the Ti adatom mean-square displacement during CMD runs, we find that Ti adatom jumps are highly correlated on TiN(001), an effect that yields lower D-s values (D-s(corr)) than those estimated from uncorrelated transition probabilities. The temperature-dependent diffusion coefficient is D-s(corr) (T) = (4.5 x 10(-4) Cm-2 s(-1)) exp[-0.55 eV / (k(B)T)].
Toughness, besides hardness, is one of the most important properties of wear-resistant coatings. We use ab initio density-functional theory calculations to investigate the mechanical properties of ternary metal nitrides TixM1-xN, with M=Mo and W, for x=0.5. Results show that Mo and W alloying significantly enhances the toughness of TiN. The electronic mechanism responsible for this improvement, as revealed by electronic structure calculations, stems from the changes in charge density induced by the additional transition-metal atom. This leads to the formation of a layered electronic arrangement, characterized by strong, respectively, weak, directional bonding, which enables a selective response to strain, respectively, shear, deformations of the structures and yields up to 60% decrease in C-44 values.
We use density functional theory calculations to explore the effects of alloying cubic TiN and VN with transition metals M = Nb, Ta, Mo, W in 50% concentrations. The obtained ternaries are predicted to become supertough as they are shown to be harder and significantly more ductile compared to the reference binaries. The primary electronic mechanism of this supertoughening effect is shown in a comprehensive electronic structure analysis of these compounds to be the increased valence electron concentration intrinsic to these ternaries. Our investigations reveal the complex nature of chemical bonding in these compounds, which ultimately explains the observed selective response to stress. The findings presented in this paper thus offer a design route for the synthesis of supertough transition metal nitride alloys via valence electron concentration tuning.
We carry out density functional theory calculations to compare the energetics of layer glide, as well as stress vs. strain curves, for cubic Ti0.5W0.5N pseudobinary alloys and reference B1-structure TiN. Irrespective of the degree of ordering on the metal sublattice, the hardness and stiffness of Ti0.5W0.5, as estimated by stress strain results and resistance to layer glide, are comparable to that of the parent binary TiN, while ductility is considerably enhanced. After an initial elastic response to an applied load, the pseudobinary alloy deforms plastically, thus releasing accumulated mechanical stress. In contrast, stress continues to increase linearly with strain in TiN. Layer glide in Ti0.5W0.5N is promoted by a high valence-electron concentration which enables the formation of strong metallic bonds within the slip direction upon deformation. [1111-oriented Ti0.5W0.5N layers characterized by high local metal-sublattice ordering exhibit low resistance to slip along < 110 > directions due to energetically favored formation of (111) hexagonal stacking faults. This is consistent with the positive formation energy of < 111 >-ordered Tio.5W0.5N with respect to mixing of cubic-BI TiN and hexagonal WC-structure WN. In the cubic pseudobinary alloy, slip occurs parallel, as well as orthogonal, to the resolved applied stress at the interface between layers with the lowest friction. We suggest that analogous structural metastability (mixing cubic and hexagonal TM nitride binary phases) and electronic (high valence electron concentration) effects are responsible for the enhanced toughness recently demonstrated experimentally for cubic single-crystal pseudobinary V0.5W0.5N and V0.5MocoN epitaxial layers.

We use density-functional ab initio molecular dynamics to investigate the kinetics of N/VN(001) surface reactions at temperatures ranging from 1600 to 2300 K. N adatoms (N-ad) on VN(001) favor epitaxial atop-V positions and diffuse among them by transiting through 4-fold hollow (FFH) sites, at which they are surrounded by two V and two N surface atoms. After several atop-V -amp;gt; FFH -amp;gt; atop-V jumps, isolated N adatoms bond strongly with an underlying N surface (N-surf) atom. Frequent N-ad/N-surf pair exchange reactions lead to N-2 desorption, which results in the formation of an anion surface vacancy. N vacancies rapidly migrate via in-plane (110) jumps and act as efficient catalysts for the dissociative chemisorption of incident N-2 molecules. During exposure of VN(001) to incident atomic N gas atoms, N-ad/N-ad recombination and desorption is never observed, despite a continuously high N monomer surface coverage. Instead, N-2 desorption is always initiated by a N adatom removing a N surface atom or by energetic N gas atoms colliding with N-ad or N-surf atoms. Similarities and differences between: N/VN(001) vs. previous N/TiN(001) results, discussed on the basis of temperature-dependent ab initio electronic structures and chemical bonding, provide insights for controlling the reactivity of NaCl-structure transition-metal nitride (001) surfaces via electron-concentration tuning.
We use molecular dynamics (MD) based on the modified embedded atom method (MEAM) to determine diffusion coefficients and migration pathways for Ti and N adatoms (Ti-ad and N-ad) on TiN(111). The reliability of the classical model-potential is verified by comparison with density functional theory (DFT) results at 0 K. MD simulations carried out at temperatures between 600 and 1800 K show that both Ti-ad and N-ad favor fcc surface sites and migrate among them by passing through metastable hcp positions. We find that N-ad species are considerably more mobile than Ti-ad on TiN(111); contrary to our previous results on TiN(001). In addition, we show that lattice vibrations at finite temperatures strongly modify the potential energy landscape and result in smaller adatom migration energies, E-a = 1.03 for Ti-ad and 0.61 eV for N-ad, compared to 0 K values E-aOK = 1.55 (Ti-ad) and 0.79 eV (N-ad). We also demonstrate that the inclusion of dipole corrections, neglected in previous DFT calculations, is necessary in order to obtain the correct formation energies for polar surfaces such as TiN(111).

We carried out a combined experimental and theoretical study of grain boundaries in polycrystalline diamond, aimed at achieving the conditions in which grain boundaries are equilibrated. Raman spectra of compacted at high-pressure and high-temperature diamond powders allow us to identify signals from sp(2)-bonded atoms, in addition to a strong peak at 1332 cm(-1), corresponding to sp(3)-bonded carbon. To verify our interpretation of the experiment, Sigma 5 (001) twist grain boundaries of polycrystalline diamond were studied by means of molecular dynamics simulations using the technique proposed by von Alfthan et al. [Phys. Rev. Lett. 96, 055505 (2006)]. We find that grain-boundary (GB) configurations, from which one atom is removed, have significantly lower energy compared to those obtained with conventional techniques. These calculated GBs are highly ordered, a few monolayers thick, in agreement with experimental observations, and are primarily sp(2) bonded. This paper underlines the importance of varying the number of atoms within GBs in molecular dynamics simulations to correctly predict the GB ground-state structure.
It is of high fundamental and practical importance to be able to control the formation and stability of the different crystalline phases of alumina (Al2O3). In this study, we have used density functional theory methods to investigate the changes induced in the thermodynamically stable α phase and the metastable θ phase as one eighth of the Al atoms are substituted for different additives (Sc, W, Mo, Cr, Cu, Si, and B). The calculations predict that the additives strongly affect the relative stability between the two phases. Most tested additives are shown to shift the relative stability towards, and in some cases completely stabilize, the θ phase, while Cu doping is predicted to increase the relative stability of the α phase. The reasons for these effects are discussed, as are possible implications on the growth and use of doped aluminas in practical applications. In addition, the effects of the additives on bulk moduli and densities of states have been investigated.
The interactions of Al, O, and O2 with different α- Al2O3 (0001) surfaces have been studied using ab initio density functional theory methods. All three surface terminations obtainable by cleaving the bulk structure [single Al-layer (AlO), double Al-layer (AlAl), and O terminations] have been considered, as well as a completely hydrogenated O-terminated surface. Adsorbed Al shows strong ioniclike interaction with the AlO - and O-terminated surfaces, and several metastable adsorption sites are identified on the O-terminated surface. On the completely hydrogenated surface, however, Al adsorption in the bulk position is found to be unstable or very weak for the studied configurations of surface H atoms. Atomic O is found to interact strongly with the AlAl -terminated surface, where also O2 dissociative adsorption without any appreciable barrier is observed. In contrast, O adsorption on the AlO -terminated surface is metastable relative to molecular O2. On the O-terminated surface, we find the creation of O surface vacancies to be plausible, especially upon exposure to atomic O at elevated temperatures. The results are mainly discussed in the context of alumina thin film growth and provide insight into phenomena related to, e.g., preferred adsorption sites and effects of hydrogen on the growth.
As one of the technologically most important ceramic materials, alumina (Al2O3) thin film growth has been studied extensively in the past. However, the mechanisms behind the formation of different phases and microstructures are still poorly understood, especially for physically vapor deposited films. An increased atomic scale understanding of alumina surface processes would thus be an important step towards a more complete understanding and control of the deposition process. In the present work, density functional theory based methods were used to study the adsorption of Al, O, AlO, and O2 on different terminations of alpha-alumina (0001) surfaces. The results show the existence of several metastable adsorption sites on the O-terminated surface and provide a possible explanation for the well-known difficulties in growing -Ñ-alumina at lower temperatures. Moreover, we demonstrate that Al adsorption in bulk positions is unstable, or considerably weaker, for completely hydrogenated surfaces, indicating that hydrogen stemming from residues in vacuum systems, might hinder the growth of crystalline alpha-alumina. Furthermore, nudged elastic band investigations of dynamic energy barriers for different surface diffusion processes show that Al diffusion, on the Al-terminated (0001) surface, requires only ~0.7 eV. This value is considerably lower than what is generally expected for the low temperature synthesis of alpha-alumina phase. These results add significantly to understanding the effects of several important factors on alumina growth, and their implication, on optimizing deposition processes for the synthesis of alumina films with desired properties, will be discussed.
Investigations of activation energy barriers for Al surface hopping on alpha-Al2O3 (0 0 0 1) surfaces have been carried out by means of first-principles density functional theory calculations and the nudged elastic band method. Results show that surface diffusion on the (most stable) Al-terminated surface is relatively fast with an energy barrier of 0.75 eV, whereas Al hopping on the O-terminated surface is slower, with barriers for jumps from the two metastable positions existing on this surface to the stable site of 0.31 and 0.99 eV. Based on this study and on the literature, the governing mechanisms during low-temperature alpha-alumina thin film growth are summarized and discussed. Our results support suggestions made in some previous experimental studies, pointing out that limited surface diffusivity is not the main obstacle for alpha-alumina growth at low-to-moderate temperatures, and that other effects should primarily be considered when designing novel processes for low-temperature alpha-alumina deposition.
We describe a theoretical analysis of the structures of self-organizing nanoparticles formed by Pt and Ru-Pt on carbon support. The calculations provide insights into the nature of these metal particle systems-ones of current interest for use as the electrocatalytic materials of direct oxidation fuel cells- and clarify complex behaviors noted in earlier experimental studies. With clusters deposited via metalloorganic Pt or PtRu5 complexes, previous experiments [Nashner et al. J. Am. Chem. Soc. 1997, 119, 7760, Nashner et al. J. Am. Chem. Soc. 1998, 120, 8093, Frenkel et al. J. Phys. Chem. B 2001, 105, 12689] showed that the Pt and Pt-Ru based clusters are formed with fcc(111)-stacked cuboctahedral geometry and essentially bulklike metal-metal bond lengths, even for the smallest (few atom) nanoparticles for which the average coordination number is much smaller than that in the bulk, and that Pt in bimetallic [PtRu5] clusters segregates to the ambient surface of the supported nanoparticles. We explain these observations and characterize the cluster structures and bond length distributions using density functional theory calculations with graphite as a model for the support. The present study reveals the origin of the observed metal-metal bond length disorder, distinctively different for each system, and demonstrates the profound consequences that result from the cluster/carbon-support interactions and their key role in the structure and electronic properties of supported metallic nanoparticles. © 2006 American Chemical Society.

Together we stand, together we fall. I am your brother, always and forever.
Ryland tucked the card on the side of the bouquet he'd handpicked for their birthday dinner's adornment and set it in the center of the table. He inhaled them one last time, enjoying the aroma of the freshly cut red roses. Now more than ever he enjoyed the simple pleasures in life, especially with Dale Mooney at his side. If only his brother would come around and take pleasure in life as he did.READ MORE
"Ah, Ryder." He fluffed out the flowers a little more. "I love you more than life itself. Why not enjoy our man as I have asked?" Ryland took one more whiff and headed for the kitchen to find his human lover busily preparing food for himself. "Mhmm, Dale, what are you cooking, my love? Smells scrumptious." And it did, despite the fact Ryland had no need to consume anything mortals ate. Ryland sauntered into the next room, sliding behind his lover, wrapping his arms around his waist.
"Ohh shi−" Dale flinched at the touch and laughed, turning his head slightly to the side. He met Ryland's gaze. "Baby, you gotta cut that out, huh? I'm real ticklish, I tell ya. At least wait until I get away from the oven."
Dale's southern accent warmed Ryland's cold heart. Gently, he planted a kiss on Dale's right shoulder. "I'll do more than tickle you, lover. That is a guarantee."
"Mhmm and I love when you do, sugah. Just broiling some fish, babe, with a little Cajun rice and veggies. Nothing too much, but I gotta stay healthy so I can give you all the blood you need."
Ryland cocked an eyebrow, laying his head on the back of Dale's neck. He sucked in a breath, enjoying Dale's manly scent. Ryland winced, feeling his cock tent in his trousers and immediately he stepped back, cursing under his breath about his desires. As much as he wanted to take his lover up on the offer, he wasn't sure he could control himself.
What if I turn him before he's ready?
Ryland couldn't bear to think of the consequences. The last thing he wanted was to take a chance on losing Dale again.
"Ry?" Dale spun around and threw the mitts on the neighboring counter. His wild blue eyes peered into Ryland's. "What's wrong, babe? I was feeling good with your cold body against my back, you know?" Dale flashed a smirky smile and held out his hands. "Come on back, babe. Wanna feel ya against me some more."
Ryland returned the grin but didn't move. "What am I, your personal air cooling unit?" He chuckled and folded his arms over his chest. "I knew you only wanted me for that; I knew it," he chided. "And your own bodyguard so no one will hurt or rob you."
Dale laughed and ran his slim fingers through his brown locks. "Ah, shut it, Ry. You know I want you for way more than that. And like I said, you need me too, so you won't go killing folks as much anymore."
Ryland's smile once again faded, and he nibbled on his bottom lip until it hurt. He loved that Dale was concerned about him, but it still didn't quell his fear of turning him too soon. "Sweetheart, I know what you said about me feeding on you, but I…I'm not sure I can control that yet. I might turn you…"
"So?" Dale stepped closer and cradled Ryland in his arms, planting a light kiss on Ryland's lips. "I want that, babe. We been seeing one another like three months now, going on four. I mean, don't you want me to be your eternal lover? No doubt, I wanna be yours." Dale stroked Ryland's hair, twirling the strands around his fingertips. "Don't tell me you're changing your mind."
Ryland closed his eyes, loving the feel of Dale's hands in his hair and underneath his shirt, caressing his cold flesh. "Of course not, lover. I refuse to turn you before it's time. I don't want it to be a situation where I need to or it is done in the heat of passion…at least not without your consent."COLLAPSE
I received a copy of Michael Mandrake's Mon Frere: Facing Our Fears in addition to the first three books in the series. I find it curious that BDSM is now mainstream, thanks to shades of gray, but other kinks are still taboo, even in a total fantasy setting. I happen to dislike BDSM, but enjoy the scenarios in Mandrake's books, all set in the N'awlins Exotica Paranormal world. I've enjoyed the ups and downs of the relationship between the two MCs Ryder and Ryland over the course of the series and am happy they seem to have worked most issues out in the current book. The secondary characters are interesting and many of them inhabit other books in the author's N'awlins realm. Part of what makes these books fun for me is the setting in post-Katrina New Orleans. I lived in New Orleans pre-Katrina and it still holds a special place in my heart. My only caveat about the Mon Frere series is that the last book assumes one has read the companion books in the N'awlins Exotica Paranormal world.

Attaching gestures works quite a bit differently in SwiftUI than in UIKit. In this episode we will look at the @DragGesture property wrapper and how we can use gestures to update custom state that we can then use to transform our UI.
SwiftUI's declarative nature makes building UIs incredibly easy. In this episode we will build a wallet UI with cards. We will create a CardView so we can reuse it in multiple places. Then we will use transforms to alter it's size and position. Finally we will see how declarative animations work as we expand the cards apart.
Now that we've seen a taste of SwiftUI, let's dive into a real example and build an app. We'll have a first look at @State variables we can use to creating a binding between our state and our UI, and we'll run into a few puzzling errors and see how we can coax Xcode into giving us the right error message.
Back from WWDC 19 and blown away by the announcements. There's a lot to cover, but we'll start by digging into the most exciting announcement: SwiftUI. This is going to change everything...

RAM Reveals the Canadian-Exclusive 2019 Ram 1500 Sport
Ram Truck have undoubtedly kept themselves in the news ever since the all-new 2019 Ram 1500 was announced at the North American International Auto Show in Detroit, and have continued that by announcing the unique-to-Canada 2019 Ram 1500 Sport model. Debuted in Toronto at the Canadian International Autoshow, the Ram 1500 Sport is being released to Canada due largely to the fact that the Sport trim has been our most popular Ram light-duty model. The truck utilizes unique exterior design cues, interior treatments and custom options to distinguish itself from other models in the Ram lineup. Starting with the exterior, the 1500 Sport features a monochromatic exterior that is available in nine different colours and is offset by a black billet bar grille with the large 'RAM' lettering grille. Standard bi-LED headlamps feature black internal bezels and are surrounded by LED daytime running lights, and an available Sport hood is available for a more aggressive look. The truck sits on a set of standard 20-in. black aluminum wheels with optional 22-in. wheels available and features a dampened aluminum tailgate with an integrated spoiler with black badging. Under the hood is the always appreciated 5.7L HEMI V8 engine that pushes out 395 horsepower and 410 lb.-ft. of torque with variable valve timing and cylinder deactivation. The HEMI is paired to a TorqueFlite 8-speed automatic transmission and is offered as either a 4×2 or 4×4 with an on demand transfer case. Offered in either a Quad or Crew Cab configuration, the Ram 1500 Sport boasts an all-black cabin with black headliner and a number of exclusive trim touches. Exclusive power heated sport cloth/premium vinyl seats with a special hex insert mesh fabric with optional leather heated and ventilated seats available. Much like the other models of the 2019 Ram 1500, the Sport model will feature the 8.4-in. Uconnect touchscreen with Apple CarPlay and Android Auto capabilities. In addition, a standard 7-in. reconfigurable in-cluster display is featured that features a unique start up screen and provides useful information to the driver. Pricing and fuel economy numbers will be announced at a later date with the truck itself expected to hit dealership showrooms sometime in the second quarter of this year.

Most of us may have already heard that CBD offers plenty of health benefits. Such positive effects include pain and inflammation relief, reduced stress levels, and a more positive mood.
However, we couldn't help but wonder how CBD does all that. In other words, how does our body react to it? The truth is, it all has to do with our endocannabinoid system (ECS).
The ECS regulates our appetite, memory, and mood. More importantly for us, it mediates the medicinal effects of marijuana.
But what is the relationship between our endocannabinoid system and CBD? Let us start by defining ECS more closely.
What is the Endocannabinoid System?
We all know that the cannabis plant produces the so-called "phytocannabinoids." Interestingly enough, our body also makes its own version of these chemicals.
Endocannabinoids (eCBs) have a similar function to that of dopamine, which is a neurotransmitter. While dopamine is a part of our nervous system, eCBs are its ECS counterpart.
The most important eCBs that our body produces are Anandamide and 2-AG (2-Arachidonoylglycerol). Anandamide former regulates memory, pregnancy, and appetite. Moreover, it's also responsible for that sense of elation after an exercise. On the other hand, 2-AG maintains heart health and controls our emotions.
Basically, the eCBs are the so-called "messengers" of the ECS. But where exactly do they deliver their messages? Why, to the cannabinoid receptors of course. They do so by binding to these receptors. That way, they affect our mood, immunity, and consciousness.
Read also: Does CBD Make You Sleepy?
Our body contains two main types of CB receptors — CB1 and CB2. The former type is important for proper brain function. We can find them in different regions of our brain, with various functions. Those include pain perception, motor function, mood, and memory. However, they are also located elsewhere in the body, although in lower levels.
The rest of our body contains CB2 receptors. Their concentration is high in our immune cells, the spleen, thymus, and tonsils. Moreover, we can find them in our kidneys and liver, as well as our skin and bones. CB2 receptors regulate our immune, gastrointestinal, and cardiovascular systems.
The Endocannabinoid System and CBD
One major difference between THC and CBD is that the former is an agonist, and the latter is an antagonist. In other words, THC activates our cannabinoid receptors, triggering their effects on our body. However, it has adverse psychoactive effects.
That is where CBD, the antagonist, steps in. By binding to our CB receptors, it will make them inactive. Thus, it will stop any further downstream activity that the receptor generates. But how does that help us?
If we ingest both these cannabinoids simultaneously, we will feel the so-called "entourage effect." Medical research has proven that CBD will mitigate the psychoactive effects of THC.
CBD can also affect our ECS indirectly, due to its weak binding affinity. For example, it can activate our TRPV1 receptors, which regulate our body temperature, pain, and inflammation.
Moreover, CBD also helps our body make more Anandamide, by inhibiting the FAAH enzyme. Thus, it improves our mood and makes us feel more motivated.
As CDB stimulates our ECS, our body reaches homeostasis more easily. The result is better sleep and less pain.

Final Thoughts
Future research has yet to discover the true nature of our endocannabinoids. Still, the interaction between our endocannabinoid system and CBD has great medical implications.
In the end, we can all benefit from better sleep, less stress, and a greater mood overall.

The scenario pitted 234 doctors against 23 online symptom checkers, websites, and apps that patients often use to come up with their own diagnosis. Who won? The doctors did, by a long-shot.
Harvard-based researchers presented the doctors and computers with 45 patient cases that included symptoms and history but no physical exam, lab tests, or imaging results. Some of the cases were serious, others more benign—26 common and 19 uncommon conditions. When it came to making a diagnosis based on symptoms and history alone, physicians were found to be far more accurate than computers.

One of our areas of expertise when it comes to providing heating and cooling for homes is geothermal heat pumps. This is a service that you won't find with many HVAC companies, which is why we're so proud to offer it to homeowners in the area.
We receive plenty of questions about geothermal heat pumps because people are curious to know if it's really possible to outfit their home with one. We're always glad to help out, especially if it means another house gets to enjoy the immense benefits that geothermal power has to offer.


text: VER250840 is a novel oral, selective Chk1 kinase inhibitor discovered by Vernalis Research. Chk1 is an important target within the DNA Damage Response (DDR) network and has been shown to play a key role in maintaining genomic integrity of cancer cells. Inhibition of Chk1 blocks cell cycle arrest and DNA repair, forcing cancer cells to undergo cell division with substantial DNA damage that results in their death. In both in vitro and in vivo preclinical studies, VER250840 has demonstrated an ability to target Chk1 in a range of different tumor types, as a single agent and in combination with several different cytotoxic agents. The clinical utility of DDR inhibitors for the treatment of cancer has recently been validated by the approval of inhibitors of Poly (ADP-ribose) polymerase (PARP). The opportunity to select patients most likely to respond to Chk1 inhibitors exists.

We have been recognized by Angie's List and maintain an A+ rating with the Better Business Bureau. If you're a Southeast Florida resident who needs garage door repair or emergency garage door service, call us today.

Pompano Beach, Florida 33069
24-Hour Emergency Service Available
Business Hours:
Monday – Friday: 7:30 AM – 5:00 PM
Saturday: 7:30 AM – 2:30 PM
Sundays: CLOSED
Broten Garage Door Sales has been the best and most comprehensive garage door repair and maintenance company serving homeowners throughout South Florida since 1955. Our team of highly trained and local garage door repair technicians is dedicated to providing all of our customers with high-quality, dependable garage door repairs using only top-notch parts, equipment and products.
For many South Florida homeowners, garages serve as the primary entrance for their homes, so it's necessary to keep your garage door and opener in good operational condition to prolong the lifespan of your garage door system, save on repair costs, and ensure home safety and security. No matter what type of garage door repair or maintenance services you need, the skilled technicians at Broten Garage Door Sales can assist you.
If you find yourself stuck inside your garage or stranded outside of it due to a mechanical issue or hardware failure, our repair experts can provide you with a quick and free service estimate and arrive at your home within 24 hours to perform repairs.
Average homeowners use their garage doors at least 1,500 times per year to safely and conveniently leave and enter their homes. With frequent daily use, it's common that you may experience garage door hardware wear and breakages.
With over 60 years of garage door repair experience, our team has seen every type of garage door issue, large or small, and can reliably and skillfully repair any garage door or opener make or model. We can assist you with several common garage door repairs, including spring and cable damage, off-track doors, garage door opener malfunctions, as well as extraordinary door repair circumstances.
Of all the common types of garage door damage, broken springs are among the most frequent issue homeowners experience. Most South Florida homeowners have either an extension or torsion spring system responsible for counterbalancing the weight of the garage door and facilitating smooth and efficient up and down door movement. While these springs are intended to last for many years without becoming damaged, typically, torsion springs are dependable for 15,000 to 20,000 cycles, or about seven to 10 years, and extension springs last around 10,000 cycles, or five to seven years.
At Broten Garage Door Sales, we can quickly and expertly repair or replace any type of garage door spring system you may have. Our highly trained professionals understand how to safely remove and replace any type of garage door spring without causing personal or property injury. For all of our garage door spring replacements, we utilize only the highest-quality spring products to ensure lasting performance and dependability.
Garage door cables work alongside the spring system to operate the door. If the springs break, the cables are likely to also become damaged and require replacement. Even if your springs are in good condition, with regular use, the cables can become worn, frayed or weakened. When your garage door cables are damaged, you may notice that your door becomes stuck or is lopsided on one end.
If you're unsure if your garage door cables need repair or replacement, contact the experts at Broten Garage Door Sales to inspect your system and recommend the next steps. We will work closely with you to find personalized solutions that fit your daily garage door needs and budget.
Being exposed to various temperatures and climates, your garage door panels can become damaged over time with dents, cracks or rust buildup. Your door panels may need to be replaced if the damage is extensive and is affecting the quality of your garage door, or if the panels have been struck recently or dented from an impact. Bent panels are not only unattractive, but heavily damaged panels can also eventually break completely and pose a safety and security risk.
Contact the professionals at Broten Garage Door Sales to explore your garage door panel replacement options.
Garage door weatherstripping is the black seal along the bottom, and often the sides and top, of your garage door. It helps protect your garage from various elements and moisture intrusion and maintains your home's internal temperature. Over time, your door's weatherstripping may become damaged or worn-out, leaving gaps between your door and the outside. Damaged garage door weatherstripping can allow water through your door and can even reduce your home's energy efficiency.
With the help of our technicians, we can quickly evaluate which type of weatherstripping product your door needs for lasting efficiency and reliability and then quickly install it onto your door.
Damaged garage door tracks are often marked by loud, noisy door operations or jerking door motions while moving open and closed. Having one of our professionals inspect your tracks can prevent further garage door damage and the need for costly repairs. We'll inspect your broken tracks and can either recommend fast repairs or replacement options.
Misaligned garage doors can encompass a variety of issues, including the door rubbing against the molding, door binding (difficulty opening or closing), a large gap beneath the door, or a crooked or off-balance door. Garage doors that have become misaligned can be caused by several issues, including damaged springs or worn hardware. Call the experts at Broten Garage Door Sales to inspect your door and identify the cause of your misaligned garage door.
At Broten Garage Door Sales, we understand how unsafe and inconvenient garage door damage can be, which is why we provide responsive and efficient 24-hour garage door repair services for homeowners throughout South Florida. Our service professionals are highly trained and experienced to handle any type of repair need, for any garage door make or model.
When you contact us for emergency services, we'll arrive at your home quickly and begin identifying repair needs and recommending affordable solutions. We only use the highest-quality parts and equipment to ensure your repairs are long-lasting and dependable.
For reliable, affordable, and knowledgeable garage door services throughout Southern Florida, call the professionals at Broten Garage Door Sales. Since 1955, we've been dedicated to offering local residents the most dependable and personalized garage door repair services and quality products.

The Strangest Thing
Right after dinner, we hung out in the cockpit enjoying the fine weather. A rowboat came by, expertly rowed by a young lady with her boyfriend talking on the phone. They, like us, were probably bored waiting around for the fireworks and decided to take a tour of the marina. The young lady was very friendly and exchanged pleasantries as she rowed by. They went down to the end of the pier and turned around.
On the way back, they exchanged places. That's when the fun started...the dude had no concept of how to row a boat (disclaimer: neither do I). They kept running into things, having to fend off, and were making absolutely no head way. We had front row seats for this and the guy was open to ridicule by my wife and 6 year old daughter (I understood as I can't row a straight line so I stayed silent).
It was fun, the young lady was enjoying ribbing him as much as we were. He finally picked up the pace a bit and made it out into the marina basin. Not without mishaps, they kept hitting pilings. As they were going to get blown a lot more by the wind in the basin, I decided to look over at them every few minutes. The second time I looked, I couldn't see them.
That's when things got strange.
I was just starting to think that I needed to run over there when I saw a hippie over on B dock pulling their dinghy out of the water. Still no sign of the people, the hippie pulled the dinghy onto the dock and then headed back to his boat to sit on the bow, crosslegged. I then see the guy's head pop out of the water in between a boat and the dock, struggling to get out. The freakin' hippie is 8 feet away, staring at the horizon, like he isn't noticing anything and hadn't just pulled a capsized rowboat out of the water. I could then see the girl by the dock but still no reaction from the hippie. It took about 30 seconds for the guy to get out of the water and then pull the girl out. The hippie must have been back in his meditative trance by then.
I called over to ask if they needed a blanket, the guy tried to act cool and said no, the girl had some sense and said yes, so I ran over with two blankets (about a 90 second run). I handed the bigger blanket to the girl thinking that if either of them needed saving, the one who could row and had the sense to accept a blanket after being in 50 degree water as night was approaching should be the one.
Granted, this all happened fast even if it seemed like it took forever but how did the hippie not notice that the people needed help? If he was in such a trance (and this trance is why I keep referring to him as a hippie, I'm now convinced he was stoned) how did he know that the boat needed to be pulled up on the dock. When I was handing them the blankets, I was 5 feet from the hippie and his gaze never wavered from the horizon.
Strange indeed. The best part was that they obviously survived since they brought the blankets back after the fireworks.

Hippies suck. I waited all week for a stirring narrative of your sail last weekend, and this is what I get?
From what I've seen of California, this seems quite normal. Although I normally associate this type of behavior with the southern half of your state.
Kudos to you, for providing the blankets. That's a tough situation. I've been the helper and, very occasionally, the helpee in similar situations. It's tough to provide help to someone without insulting them.

Wait a minute. Didn't this used to be a "bloglet". And now it's a "SuperBlog"? When did it change and why? What does it mean? Inquiring minds demand to know.
- EVK4 said...
Yeah, I'm re-branding to superblog just in time for my lamest post of the year. My timing could have been better.
- Zen said...
You did good, But...WTF why does the guy have to be a hippie? He could have just been a stoner, crackhead, spaced out dude, powerboat guy,hermit, landlubber, yogi, a republician! You been watching too much southpark dude. Why the hippies got to get the bad rap?!? Give the hippies a break! Hippies are people too! peace! :-)
- Zen said...
wow I commented on a superblog!!
way cool!
or better yet...
FarOut man!
- Tillerman said...
Hmmm. It's not that I'm competitive by nature but I do hate being upstaged by a SuperBlog. I may have to do some rebranding myself but how can I go one better than SuperBlog?
Proper Course could become Righteous Heading or Holy Vector perhaps? Doesn't really roll off the tongue does it?
- EVK4 said...
Zen, "why does the guy have to be a hippie"? I asked myself the same thing...couldn't he have been a frat boy, a glaucoma patient, a raver, or some other stereotype that smokes pot? But no, the guy was a hippie, not my doing and until I stage the intervention I'm powerless to help.

Insurmountable Odds, Book One of When Stars Fall.
It is done.
Long have I laboured, etc. et al. I can't tell you how damned good it felt to hit the final 'Save' on the document, and Wendy suggested a tweak to the closing paragraph which hit the nail on the head. And I promise, it is definitely, finally, ultimately, no more changes, no more tweaks, adjustments or refinements, done. Complete. Ready.
I have written quite a lot in the past – none of which has ever gotten to the point of being publishable (even self-publishable). I'm damned proud of Book One, I just hope it is judged 'worthy' by fellow sci-fi readers!
Now, on to ePub world, and deciding how I can promote this whole affair…

Its move follows the appointment of Britain in Europe campaign director Lucy Powell as head of media and PA. It has emerged she joined the government body in March. Edelman was hired last August.
Nesta executive director of corporate comms Angela Salt has merged the comms and PA teams, and is recruiting for a head of corporate comms to boost the organisation's brand, and for a media and PA manager who will report to Powell.
Salt, who joined last month from the Electoral Commission, said Nesta's strategy was to 'focus on people, money and policy' – nurturing skills, providing finance and fostering the right policy climate for British innovation to flourish.
Created in 1998, Nesta supports innovations such as a 'micro-pump' that is worn like a plaster by diabetics to administer insulin.
