Keynote: Design of Pd-based nanoalloy particles confined into mesoporous carbon: Size, composition and confinement effects on the interactions with hydrogen
Time : 10:00-10:30
Camelia Matei Ghimbeu is a Researcher at Institute of Materials Science of Mulhouse (IS2M-CNRS), France. She received her PhD from University of Metz in 2007, France and TU Delft, The Netherlands and her Habilitation in 2015 from University of Haute Alsace, France. She is the author of 55 articles and about 100 communications, her research interests are focused on the design of carbon hybrid materials with controlled characteristics for energy storage and environmental applications. She is animating the research axe "Carbon and Hybrid Materials" at IS2M, and she is member of French Network of Electrochemical Storage of Energy (RS2E).
Supported metal nanoparticles (NPs) with well controlled size, dispersion and shape are of great interest in many fields of applications. They exhibit large surface to volume ratio, faster molecular diffusion pathways and synergetic effects rising from the interaction with the support. Mesoporous carbons are widely employed to support such particles affording good stabilization through nanoconfinement effects leading to small and well dispersed NPs. Supported Pd-based alloys with noble or transition metals on carbon are tremendously studied in catalysis while hydrogen storage studies are scarce. In the present work two main strategies were developed to synthesize a series of Pdx-M100-x alloys NPs (where M=Co, Ni, Rh, Pt and x=10, 25, 50, 75, 90) having different compositions, tunable particle size and location in the carbon network. The first approach is the incipient wetness impregnation of carbon host with a metallic solution, followed by hydrogen reduction at 300-500°C while the second approach is a one-pot method where the metallic particles are formed in-situ during the synthesis of carbon framework at 600°C. The optimization of NPs size was achieved by tuning several metal salt type, carbon precursors, cross-linkers and thermal reduction temperature while their location was directed mainly by the type of synthesis approach. The impregnation
favor the NPs location into the pores, while the one-pot in the walls of carbons. For several studied systems, alloy particles were formed in the whole composition range as highlighted by the linear relationship between the lattice parameter and the composition (Fig. 1a). Small particles with sizes ranging between 1.5 and 50 nm were prepared (Fig.1), the incipient method allowing obtaining always smaller particle sizes than the one-pot method (Fig. 1left). The hydrogen interactions with the nanoalloys were strongly influenced by their composition, size and confinement in the carbon network.

Nanofluids are homogeneous dispersions of nanoparticles in conventional base fluids which constitute an emerging type of unique liquid materials within the field of Nanoscience and Nanotechnology. They have been proposed and used for a variety of applications with very special emphasis on thermal properties and heat-transfer applications. Indeed, solids present better thermal conductivity and specific heat capacities than liquids but dispersing solid micro particles in fluids leads to clogging, a problem which is solved with nanoparticles. On the other hand, other energy-related applications are possible for nanofluids which have not been explored until very recently. In our group we are developing two different research lines dealing with nanofluids i) nanofluids for thermal applications and ii) Electroactive Nanofluids (ENFs) for energy storage in novel flow cells. The latter type includes a wide variety of nanofluids containing nanoparticles able to store electrical energy, whether through redox or capacitive mechanisms. We will present an overview of the use of nanofluids in the field of energy, from thermal to electroactive nanofluids with some final focus on our own recent results, including the first example of the application of ENF materials for the development of fast energy storage in flow cells. In this case, we have used a capacitive nanofluid based on graphene which would be the flow-cell analog of solid-electrode graphene supercapacitors.

Technology at the nanoscale has become one of the main challenges in science as new physical effects appear and can be modulated at will. Superconductors, materials for spintronics, electronics, optoelectronics, sensing, energy applications and new generations of functionalized materials are taking advantage of the low dimensionality, improving their properties and opening a new range of applications. As developments in materials science are pushing to the size limits of physics and chemistry, there is a critical need for understanding the origin of these unique physical properties (optical and electronic) and relate them to the changes originated at the atomic scale, e.g.: linked to changes in (electronic) structure of the material. In the present work, I will show how combining advanced electron microscopy imaging with electron spectroscopy, as well
as cathodoluminescence in an aberration corrected STEM will allow us to probe the elemental composition and electronic structure simultaneously with the optical properties in unprecedented spatial detail. The talk will focus on several examples in advanced nanomaterials for optical, plasmonic and energy pplications. In this way the latest results obtained by my group on direct visualizing and modeling materials at atomic scale will help to understand their growth mechanisms (sometimes complex) and also correlate their physical properties (electronic and photonic) at sub-nanometer with their atomic scale
structure. The examples will cover a wide range of nanomaterials: Quantum structures self-assembled in a nanowire - quantum wires (1D) and quantum dots (0D) and other complex nanowire-like morphologies for photonic and energy applications (LEDs, lasers, quantum computing, single photon emitters, water splitting cells, batteries), nanomembranes and 2D sheets; as well as metal multiwall nanoboxes and nanoframes for 3D plasmonics.

Title: Physical, chemical and toxicological characteristics and historical trends of ultrafine particulate matter from traffic emissions in the Mega City of Los Angeles
Constantinos Sioutas is the first holder of the Fred Champion Professorship in Civil and Environmental Engineering at the University of Southern California (USC). His research has focused on investigations of the underlying mechanisms that produce the health effects associated with exposure to airborne ultrafine particulate pollutants generated by a variety of sources. He has developed many state-of-the-art technologies used by many academic institutions and national laboratories for aerosol sampling and characterization. He has authored over 300 peer-reviewed journal publications, and holds 13 US patents in the development of instrumentation for aerosol measurement and emissions control. His work has been cited in more than 15,000 scientific publications. He is the recipient of the American Association for Aerosol Research (AAAR) David Sinclair Award in 2014 (AAAR's highest distinction), the Hagen Smit Award of Atmospheric Environment for Seminal Publications, the 2010 Scientific and Technological Achievement Award by the US Environmental Protection Agency, and a Fulbright fellow.
To determine the organic constituents of ambient ultrafine particles (<0.18 um) and quantify the source contributions to PM0.18 organic carbon (OC), a sampling campaign was conducted at Central Los Angeles (LA) from 2012-2013. A novel hybrid molecular marker-chemical mass balance model was introduced and applied to estimate the contributions from mobile sources (including gasoline, diesel, and smoking vehicles), wood smoke, primary biogenic sources, and anthropogenic secondary organic carbon. Based
on the model output, a 57% decrease in contribution of mobile sources to the total OC from 2009 to 2013 was estimated. Comparison to previous studies in Central LA indicated significant reduction in concentrations of carbonaceous species such as polycyclic aromatic hydrocarbons druing the past decade. The analysis of historical trends in ambient PM oxidative potential measured by dithiothreitol (DTT) assay enabled us to assess the relative importance of tailpipe and non-tailpipe emissions on DTT activity in this area. Ambient PM0.18, the toxicity of which was found to be mainly dominated by tailpipe emissions, showed a consistent decrease in DTT activity levels in the past decade, likely due to major reductions in tailpipe emissions as a result of stringent regulations on mobile sources in the LA basin. Despite major reduction in ambient PM2.5 levels and vehicle tailpipe emissions, a slight but consistent increase in
the DTT redox activity of larger particles (PM2.5) was observed in the past decade. A follow-up on-road sampling campaign was conducted using a mobile instrumentation platform on major freeways of Los Angeles revealed the important role of both tailpipe and non-tailpipe traffic emissions on the overall oxidative potential of PM2.5. Increased contributions of certain groups of metals and trace elements that are indicators of non-tailpipe emissions compared to previous studies provide evidence on the increasing importance of non-tailpipe emissions to the oxidative potential of on-road PM2.5 as vehicule tailpipe emissions becomes cleaner.
Carlo Naddeo
University of Salerno, Italy
Title: Heat transport in tetra-functional epoxy resin containing low percentage of exfoliated graphite nanoparticles
Carlo Naddeo is a Physicist currently in service at University of Salerno - Department of Industrial Engineering as Assistant Researcher. He actively collaborates in research activities related to the study of physical properties and durability of functional and structural polymeric materials and nanocomposites. As part of these collaborations, he has produced over 50 publications in international journals and more than 40 contributions at conferences.
Thermal management with conductive polymeric nano-composites has become a central task of industrial interest for many applications ranging from exchangers in electric and electronic systems to electronic packaging and photovoltaic devices. In order to enhance the thermal conductivity of polymeric composites there is a tendency to incorporate thermally conductive nano-fillers in the polymeric matrix. Actually the most widely used are the carbon nanotubes (CNTs) due to their outstanding mechanical, electrical and thermal properties together with a high aspect ratio and surface area. The incorporation of CNTs into the polymer matrix has significantly enhanced mechanical and electrical performance of final composite material but until now the desired enhancement in thermal conductivity has not been achieved. The aim of this work is to carry out a preliminary experimental investigation of thermal properties and heat conduction in epoxy nanocomposites prepared by dispersing low concentrations of different kinds of nanofillers, such as 1-D multiwall carbon nanotubes and 2-D predominant shape exfoliated graphite (EG) within an aeronautic resin based on a tetrafunctional epoxy precursor. For the analyzed epoxy formulations the best results are obtained using EG as nanofillers. The curing degree for the EG-based epoxy nanocomposites cured up to 200°C is very high compared to unfilled epoxy resin, reaching up to 100%. EG nanoparticles also accelerate the curing process of the epoxy resin of about 20°C and this is most likely due to better phonon conduction through carbonaceous nanostructures with predominantly two-dimensional flat shape. This is confirmed by experimental values of thermal conductivity that show an increase of 300% for 3% of Exfoliated Graphite embedded in tetrafunctional epoxy resin. In light of these results it is clearly evident the potential of 2-D graphene sheets as promising nanofillers able to meet the ambitious requirements in the thermal management for high-performance nanocomposites.
Ramon J Peláez
Institute of Optics, Spain
Title: 2D plasmonic diffractive patterns in metals by laser interference
Ramon J Peláez obtained his PhD from Valladolid University and obtained his first Post-doctoral training at Laboratoire Aime-Coton (CNRS). He is currently a research fellow Post-doc at the Institute of Optics (CSIC). He has published more than 45 papers in specialized and peer-reviewed journals. His research interests in the field of nano-materials include periodic nanostructured materials, plasmonic metal nanoparticles, nanostructures generated by pulsed laser deposition and laser induced dewetting.
Optical phenomena related to the electromagnetic response of metals led to the development of the emerging field of plasmonics. Electron density of metal nano-particles can couple with the electromagnetic radiation and plasmons are the oscillations of the free electrons related to the formation of a dipole in the nano-particle. The progress in the manipulation and synthesis of these objects in the last years allowed us to apply these optical properties in a great variety of applications from efficient light absorption in solar cells to DNA spectroscopy detection. Today, one of the major challenges is the effective production of surfaces with customized visual color effects with direct applications in the development of personal identification systems according with the quest of the enhanced police security. Laser interference is a versatile technique for the production of 1D and 2D patterned surfaces. When applied to metal films, the laser irradiation induces the periodic dewetting of the metal from the substrate resulting in the formation of nanoparticles. These nanostructures are optically characterized by their surface plasmon resonance in the visible range, which in turn depends on the size or metal composition. Optical contrast between the regions transformed into nanoparticles and non-transformed regions (diffraction efficiency) can be tuned. In this work we report the production of bimetallic diffractive structures, with different [Ag]/ [Au] ratio and different motives within periodicities in the range between 1.7 microns to 6.8 microns. We will present experimental data showing that these regions have different diffraction patterns according with the periodic motive and the optical response of the nanoparticles. Thus, this technique allows a personalized optical signal to be encoded with a time-efficient and single-step laser technique.
Yves Huttel
Instituto de Ciencia de Materiales de Madrid, Spain
Title: Gas Phase synthesis of Nanoparticles: Challenges and Opportunities
Y Huttel is Doctor from the University of Paris-Sud, Orsay, France (1995). After his degree, he worked at the Synchrotron LURE, France; at the University of Paris-Sud, France; and at the ICMM-CSIC, Spain. He was also a Postdoctoral Researcher at the Synchrotron of Daresbury Laboratory, UK, before returning to the CSIC at the IMM. He joined the Surfaces, Coatings, and Molecular Astrophysics Department at the ICMM that belongs to the Consejo Superior de Investigaciones Científicas (CSIC), Spain, with a Ramón y Cajal Fellowship. Since 2007, he has been working at the ICMM as a Permanent Scientist and leads the Low- Dimensional Advanced Materials Group. His research focuses on low-dimensional systems including surfaces, interfaces and nanoparticles, as well as XMCD, XPS and nanomagnetism.
The increasing demand of pristine nanoparticles in nanotechnology is driving a strong effort in finding new methods and technologies for the synthesis of nanoparticles (NPs). Although the wet chemistry methods are the most popular due to their relative low cost and mass production capacities, the gas phase synthesis of NPs is getting more attention thanks to its specific advantages. This physical method is based on the evaporation of a given material (that could be performed by Laser ablation, evaporation, sputtering, etc.) followed by a controlled aggregation of the produced ions and neutrals in order to produce clusters or
nanoparticles. Since the whole process can be performed under well-controlled environment (vacuum or ultra-high vacuum) the produced nanoparticles have the same chemical composition as the base material that has been evaporated and lack of contaminants. Also the gas phase method produces quite narrow size distributions that can be tuned and even improved by the use of filtering techniques and it produces NPs that are free of ligands or surfactants that can be deposited or embedded directly on surfaces and matrices. This talk will be devoted to magnetron based Ion Cluster Sources (ICS) that have proven to be well-suited for the fabrication of pristine NPs. After a brief review of the ICS, I will address some issues that have limited the use of the ICS in industrial processes and present solutions for the scaling-up of the technology. In particular, through examples I will present the so-called Multiple Ion Cluster Sources (MICS) that has been shown to be very versatile for the production of alloyed and core-shell NPs.

The phenomenology related to the growth of fullerene and graphene based nanostructures leads to a varied morphology, which depends critically on growth conditions. How to control this morphology through technology is a task requiring an exploration of new ways and modification of widely extended technologies like the classical chemical vapor deposition. In this presentation, we take a walk through a series of results achieved in our research group, with the intention of ordering in some way the many
graphene and fullerene forms found and the CVD based technologies used. The resulting morphology is extremely varied and critically dependent on the growing conditions like precursor nature, gas mixture, temperature, pressure, plasma, gas flow rate. Also, resulting morphology depends on substrate nature and its structure, and surface morphology. We have explored different conditions and substrates like copper and stainless-steel foils, Cu/c-Si, Ru/c-Si, SiO2/c-Si, quartz, Cu/quartz, in order to find the
carbon nanostructures characteristics more suitable for applications like electrodes, and planar sensors and devices.

Title: Effects of process parameters on chemical functionalization of helicoil carbon nanotubes
Sean Reza Taklimi, currently, is a PhD candidate in the Mechanical Engineering Department of Wichita State University (WSU), USA. He has expertise in functionalization and characterization of nanomaterials, specifically, carbon nanotubes. He received his Bachelor's degree in Chemical Engineering from Sharif University of Technology in Iran and Master of Science in Mechanical Engineering from Linkoping University, Sweden. His PhD research work is mainly focused on improvement of the mechanical properties of composite materials, using different types of nanomaterials. In the past, he has also worked as Research and Development Engineer in the area of energy and environment; furthermore, he has participated in and managed different projects during his job.
Functionalization of carbon nanotubes with helical configuration was performed through a reflux technique; furthermore, the influence of time and temperature as two key parameters of the treatment process were investigated. To evaluate the effectiveness of the process parameters, the functionalized helicoil nanotubes (HCNTs) were analyzed using various characterization instruments such as, Raman Spectroscopy, Visual Dispersion Test, Fourier Transform Infrared Spectroscopy (FTIR), Scanning Electron Microscopy (SEM), and X-ray Diffraction Spectroscopy (XRD). The characterization results showed that most processes parameters were effective and the surface of HCNTs were successfully modified. The functionalized HCNTs demonstrated a higher solubility and more uniform dispersion rate compared to pristine HCNTs. The results also showed that increasing the reflux time and process temperature had no obvious effects on the solubility of HCNTs. On the other hand, prolonging of process time increased the (D/G) ratio in Raman spectrum and changed the intensities and places of the FTIR peaks. With the exception, for the functionalized HCNTs which were treated for 24 hours, all other samples exhibited at least a change in FTIR spectrum.
Swasti Wagh
Precedent of Indore Chapter of SAMAG (Seek a Miracle Ataxia Group), India
Title: Magnetic nanoparticle/ magnetic fluid approach to control neuromuscular degeneration in Friedreich's ataxia
Swasti Wagh has completed her MSc in Applied Mathematics in the year 1999. She is fighting with F.A. since last 25 years and now she is on a wheelchair. She has some research publications on Magnetic Fluid. Recently, her paper on Mathematical Modeling of F.A. is accepted for publication. Since last 10 years, she is organizing camps for ataxia awareness and for the welfare of ataxia patients. She gave a presentation at SNCI conference held at AIIMS, Delhi in Feb 2013 and a presentation in DSHD congress on FA held at AIIMS, Delhi in April 2015.
In last two decades nanotechnology has brought a revolution in the advancement of material science, biology, biotechnology, genetics, medicine and many other areas of science and engineering. The ability of nanotechnologist to prepare material particles of nano size, coating them with a suitable surfactant and magnetizing these particles has made possible to study micro level biological entities such as cells, genes and proteins. In recent years magnetic nanoparticles have been used in cancer treatment, drug delivery and in many other medical fields. This leads us to think why this technology should not be introduced in F.A. research for which no treatment is available and patients suffer with lethal neuro- degenerarative condition of F.A. making them totally dependent on others for even the simple day to day activities. The disease is genetic and unknowingly passes on in off-springs through the carrier parents. It is therefore necessary to control degeneration in F.A. patients and make their life comfortable. Friedreich's ataxia (FRDA) is an autosomal recessive inherited disease caused by (GAA) expansion of the FXN (frataxin) gene. FRDA is predominantly a neurodegenerative disease. It manifests in initial symptoms of poor coordination such as gait disturbance; it can also lead to scoliosis, heart disease (cardiomyopathy) and diabetes. FXN gene produces frataxin protein which is localized to the mitochondria. The function of FXN is not entirely clear, however, the primary role of FXN protein is the activation of iron-sulfur (Fe-S) cluster biogenesis in the mitochondria. In F.R.D.A. production of FXN protein is reduced. In affected individuals level of FXN drops approximately 5 to 30% than healthy individuals. The role of FXN protein is that of an iron chaperone, a companion of iron particle. Low FXN levels lead to insufficient biosynthesis of iron-sulfur clusters that are required for mitochondrial electron transport chain to ultimately generate adenosine triphosphate (ATP), the energy packet necessary to carry out metabolic functions in cells. FXN also regulates iron transfer in the mitochondria in order to provide a proper amount of reactive oxygen species (ROS) to maintain normal processes
without FXN, the energy in the mitochondria falls, and excess iron causes extra ROS to be created, leading to further cell damage. Nanotechnology can be useful to solve this problem. We can introduce body compatible magnetic nanoparticles to pickup iron particles and direct them to sulpher to form iron-sulpher clusters. Thus iron-sulpher clusters can be formed even in the absence of FXN protein in F.A. patients. And thus the process of respiration in mitochondria will continue to produce energy in the form of ATP. As iron particles are utilized in formation of iron-sulpher clusters no free iron is left to get deposited on cells and cause cell death in FRDA patents.
Lauryanne Teulon
Université de Toulouse, France
Title: Sorting of nanogel mixed dispersions by directed assembly on surfaces using AFM nanoxerography
Lauryanne Teulon is currently a PhD student in INSA – Université de Toulouse, LPCNO. She has completed her graduation from the Engineering School of Centrale Marseille. She is now studying anti-counterfeiting tags made by an innovative technique, so called AFM Nanoxerography. Her research interests are nano-objects directed assembly, nanogels and microfluidic devices.
This work presents a simple approach for directionally assembling thermoresponsive colloidal nanogels onto surfaces in minutes using AFM nanoxerography. Charge patterns written by AFM are used as electrostatic traps to obtain complex directed assemblies of anionic nanogels (N- isopropylacrylamide copolymerized with acrylic acid) and cationic nanogels (using quaternary
ammonium functional groups). Mixed dispersions of these two types of hydrogels are also selectively sorted onto combinations of negative and positive charge patterns in various manners depending on the ratio between the concentrations of each nanogel type. Taking advantages of the fast and high resolution nanoxerography technique, this work offers a new way to separate soft nanoparticle aqueous dispersions onto surfaces. It also allows one to obtain information about the effective charge and proportion of the different nanoparticle species present in mixed colloidal dispersions and to make enviro-intelligent and tunable coatings.

Title: Synthesis of FePO4•2H2O nanocomposites for fabrication of lithium ion battery using impinging stream reactor
Bin Dong is currently a PhD student at International Doctoral Innovation Centre, University of Nottingham Ningbo China. His research expertise is on materials fabrication, characterisation and electrochemistry.
An impinging stream reactor has been adopted for synthesis of nanoscale FePO4.2H2O particles. The experiments indicate that the application of the impinging streams is able to significantly enhance the mass transfer rate of the reactant solutions through strong turbulent eddy interactions due to the impingement of two narrow reactant streams at high velocities. The FePO4.2H2O nanocomposites were synthesised under the conditions that pH value (pH=1.2, 1.4, 1.6, 1.8 and 2.0), reagent concentration (C=0.5, 1.0 and 1.5 mol L-1), and volumetric flow rate (V=17.15, 34.30, 51.44, 68.59 and 85.74 mL min-1) were precisely controlled. Effects of the pH value, reagent concentration, and volumetric flow rate on synthesis of FePO4.2H2O nucleus have been studied when the impinging stream reactor is to operate at nonsubmerged mode. The as-synthesised FePO4.2H2O and corresponding LiFePO4/C prodcuts were characterised by applying XRD, SEM and charge-discharge test. It has been demonstrated that under the optimised opertation condition (pH=1.6, C=1 mol L-1, V=85.74 mL min-1), the LiFePO4/C possesses the best charge-discharge performance while the discharge capacities is able to reach 152.6, 146.9, 139.1, 130.4 and 118.2 mAh g-1 at 0.1 C, 0.5 C, 1 C 2 C and 5 C current rates, respectively. It was revealed that the LiFePO4/C synthesised at pH=2.0, C=1 mol L-1, V=85.74 mL min-1 has the most stable cycling performance with the discharge capacities reaching 140.6 and 141.8 mAh g-1 at a rate of 0.5 C at the first and the 100th cycles, respectively.

The fast-growing nanotechnology provides every day new type of materials to fulfill the biomedical needs. Whereas infections caused by pathogenic multidrug-resistant bacteria has become one of the most worrying problems that the human health and economy suffer from and what makes the development of new effective alternatives to classical antibiotics an urgent need. Nanotechnology has generated a novel class of photothermally sensitized agents –gold nanoparticles (AuNPs). Depending on the phenomenon of surface plasmon resonance of noble metal nanoscale particles new therapy has been established called plasmonic photothermal therapy (PPTT). PPTT has attracted new interest in cancer therapy and also against microbes. The current research aims to assess the PPTT of AuNPs against Gram-negative Escherichia coli (E. coli) and Gram-positive Bacillus cereus (B. cereus) bacteria. Different concentrations of AuNPs capped with different polymers (polyvinyl alcohol (AuNPs -PVA) or Polyvinylpyrrolidone (AuNPs -PVP) were applied on E. coli and B. cereus in dark and under the irradiation of several doses of the light emitting diode (LED 530 nm). Results showed that the maximum antibacterial effect occurred at 10 μM of AuNPs -PVP in the presence of 0.9 J/cm2 of LED. Finally, it was concluded that PPTT with gold nanoparticles considered as an effective method for bacterial eradication as AuNPs induce hyperthermia in the surrounding environment of bacteria upon irradiation which causes cell damage. Also, the capping material of AuNPs plays an important role in its biological effect.

The Iroquois Theater Fire goes down in history as the single deadliest structural fire in US history, due mainly to disregard for fire safety regulations.
Among the many mistakes that led to the deaths of 602 theater-goers on 30 December 1903 were the structural flaws of the Iroquois Theater itself. The Iroquois Theater did not comply with contemporary fire codes. Its rooftop vents were incomplete, causing many to die from smoke inhalation when fire broke out during a matinee performance. Fire exits in the theater were unfinished and badly placed; the fire doors were difficult to open, and were hidden behind curtains. Most of the lobby doors were locked when the fire broke out; patrons in the balcony area of the theater found themselves trapped by locked gates on the balcony stairs.
In the wake of the Iroquois Theater Fire, fire codes in the US and Europe were reformed. The new laws stipulated that fire exits be clearly marked, and hinged so that they could be opened from inside or out. The Von Duprin company invented the first panic exit device following the Iroquois Theater Fire; this device is still used in high-occupancy structures today.

Now that a couple of weeks have gone by and smoke is no longer billowing out of my ears, I am ready to write about my latest trials and tribulations of raising a tween son. I know in the scheme of things this is not a big deal (I could have found much worse), but I can't even tell you how angry I was the day I found my son's lunch at the bottom of his backpack! You'll understand why I went coo coo for Cocopuffs when you read the rest of my post.
Why was I digging around in my 11 year old's backpack? Well, once again on a Sunday afternoon we found ourselves doing the homework fire drill. My son had a big music project due the next day--one that he could not remember any details to (I swear the kid suffers from memory loss). He conjured up what little he could on what he was supposed to do, but I knew there were more pieces to the puzzle. So I put on my Sherlock Holmes hat and started investigating.
Unfortunately my go to gal's son was not in this class with my son, so I needed a new starting place. First, I went on the teacher's website to see if he had the project posted--no luck! I thought all of his teachers used the teacher's web but evidently not. Next, I grilled my son, hoping that maybe one question would spark a memory--nada. And then, I went to the backpack, figuring maybe there was a sheet crumpled up in there somewhere. And of course THERE WAS!!! AND in addition to finding the assignment, I found not 1, not 2, not even 3 but 7 untouched peanut butter and jelly sandwiches (ah, ah, ah,--this is my Count from Sesame Street reference)!
I just about flipped my lid! I couldn't believe it! The fact that I had just found his non-existing assignment flew out the window and all I could focus on were the smashed, flattened PBJ's! I was so angry, I thought I was going to cry (I'm still working on not letting my anger turn to tears--it is a long process). I quickly yelled for my husband (I needed back-up) and son. I then gave my son a thorough tongue lashing that went something like this---How could you let me make you sandwiches day after day and not eat them? Don't you know there are children starving in _______! How come you didn't tell me you'd rather eat something else? Don't you respect my time and efforts enough to eat your lunch? My ranting went on and on until finally my husband calmed me down. Man was I angry!
When I finally was able to speak, in a voice that more than dogs could hear, I told him that not only was ditching his lunch wasteful but disrespectful of my time. I also threw in a dose of guilt by telling him that my feelings were hurt. And when asked the inevitable question
"Why?" he answered that he was now a peanut butter only man. Evidently it was his new aversion to jelly that made him turn his nose up to his sandwiches--who knew??

Art Adams has a detailed writeup on his experiences with the Sony FS700:
I excel at talking about actual usability: How is it to work with? What is it good for? What is it bad for? What are the "gotchas"? What do I really need to know to get the most out of this camera in a production environment?
…opening up the stop on an FS700 is a pain when using still lenses as you have to crank in a ton of ND and then spin, spin, spin the aperture wheel to bring exposure back to the point where you can see something to focus on. This takes 10-20 seconds per shot, and sometimes I just want to get the shot and move on–or grab a shot before it goes away. I learned the hard way, though, that this is a shortcut you can't take with the FS700.
In 4K you really need to make sure something is in sharp focus at all times or the image will look soft overall.
When I first saw 4K images on a monitor down at Sony Studios I was blown away by the detail. I was also completely confused by where I should be looking, and some images were so complex I had minor panic attacks trying to take in all the detail before the edit occurred. Part of the art of cinematography is guiding the viewer through the frame, and that's never been more important than in 4K display.
Linear gamma is how silicon sensors see the world. The first 50% of the signal generated by light hitting the sensor goes to the first full stop of dynamic range, usually the brightest highlights. Half of what's left goes to the next stop down, and half of that goes to the next stop down, etc. This is a hugely inefficient way to store data, but it's the only way to preserve everything the camera saw. The most important aspect of shooting raw is that de-Bayering algorithms improve over time, which means that it's possible to go back and get better color and highlight detail out of old footage simply by using newer software.
The price we pay for this is that the amount of data we need to record is HUGE.

Jobs News Is Good News for Bush
ECONOMISTS PREDICT BUSH will get more good jobs news.
Payrolls are expected to rise an average of 177,000 every month for the next year, according to forecasts from 54 economists surveyed by WSJ.com. That is much less than March's 308,000 gain, but more than double the 75,000 average of the preceding six months.

Barnett III's brother-in-law was Richard Hopkins (1763-1810), head cook at Trinity Hall and Caius College. He was also a brewer, and made and sold brawn – a meat jelly made from the head of a pig or calf.
In 1805 the renowned essayist and food lover Charles Lamb (1775-1834) was given some of Hopkins' brawn by a friend as a present. Lamb wrote a fulsome letter of thanks in praise of Mr Hopkins and his delicious meat produce. After his death, Richard's widow Sarah continued all his businesses, including as cook at Trinity Hall and Caius College.

The IGF's flagship policy guidance and assessment tool is the Mining Policy Framework (MPF). The MPF lays out international best practices in six key pillars of mining policy and law: the legal and policy environment; financial benefit optimization; socioeconomic benefit optimization; environmental management; mine closure and post-mining transitions; and artisanal and small-scale mining.
MPF Pillar 5: Mine Closure and Post-Mining Transitions
Alec Crawford, IGF Associate
"The post-mining transition is our fifth pillar and this is focused on a few things. So there is, within the MPF, standards relating to the development of mine closure plans. And are those plans required for companies before they are granted permits? What would those plans look like? Are they reviewed and revised on a regular basis throughout the operation of the mine?
Another part of that pillar is about financial assurance. Are there requirements in place to guarantee that the operator of the mine can cover the cost of closure or, at least planning to cover the cost of closure, so that governments aren't left with abandoned mines should something happen to the operator.
The third part of it is really about this question of abandoned and orphaned mines. Is the government taking a leadership role with regards to these resources and the cleanup of these resources so that they are not simply left to the local communities—that would obviously be detrimental to those local communities."

Introduction to PH 212
Physics is more than just a bunch of facts to be memorized or problems to be solved, it is a living discipline. Physics is a study of nature. Learning the basics of physics promotes seeing your everyday world in a whole new way. Physical models can be used to describe fundamental natures of systems, often by making simplifications. Once the simplified system is understood, more aspects of physics can be added to model an increasingly complicated system.
Physics 212 is the second course in a three quarter sequence, offered by the Oregon State University Physics Department. You need a good working knowledge of the topics in PH 211 to do well in this course.
You need a good working knowledge of kinematics, as we will study the angular equivalent in circular motion.
You should understand how to solve problems in the Newtonian force framework. This term, we will study the angular equivalents.
We will also study conservation. Just as momentum is conserved in the absence of external forces, angular momentum is conserved in the absence of external torques.
Problem solving begins with understanding the physical system involved and application of the appropriate underlying assumptions. Next, draw a good diagram. The diagram should then be used to create appropriate graphs or diagrams, such as free-body diagrams. The graph or diagram is used to construct a set of mathematical equations. One of the major flaws in the way folks typically approach physics problems is to jump right to the math, missing the underlying understanding of the system. As the systems become more difficult, paying attention to the underlying physics becomes increasingly important.
The second half of this course deals with oscillations and waves, and applications of wave theory to sound and light, such as wave optics. We also discuss ray optics and finish by considering the topic of gravity.

I try to keep this blog as diverse as possible...not to be PC but because I love all the boys of the world equally (best. person. ever. (me)). Though it's a bit hard sometimes in Paris because they like to keep all the non-whites outside of the city.
But there is one race which I have never posted: Christians! And holy shit, besides the homophobia and republicanism and xenophobia...are they ever babes!!!! Don't they just look like they only eat corn. Ever.
These two are brothers who wear matching vests and poofy pants and juggle and say Christian things like "boy that went over like a fart in church!" (why? is that a good thing? do people fart in church? what are these crazy cultural references?) or "I had to break up with my girlfriend over religious differences, see I'm a Christian and she's the devil" . HOOTHOOTHOOT...The devil! Good one! Who would want to go out with him!!!
It made me feel like a man in the early Britney Spears days. Like how you want to touch all the paintings at the gallery because of the "can't touch this" sign. But in this case the sign is an abstinence contract.

Modern Home Remodel
This home received a top to bottom make over. On the top floor, a master suite was created. A guest bedroom was repurposed into an exercise room. By moving one of the guest bedroom walls a computer nook was created. The master suite boasts a deck that was doubled in size, which created more outdoor living space and also provided cover for the lower deck area. The master closet and bathroom were redesigned. On the main floor the entry was redesigned from the new stone patio and steps to the water feature. The sunroom was removed and walled in to create a large closet for the second bedroom and reduce the street noise. The hall entrance to the kitchen was reconfigured to allow for a bigger kitchen. A stainless steel Dacor appliance package gives the kitchen a professional feel. The main floor bathroom and laundry were also remodeled. New hardwood flooring updated and unified the living and dining rooms.
A new sleek gas fireplace was installed. The deck was rebuilt using composite decking and glass railings. A new, custom spiral staircase connects the main floor to the two car garage and mother-in-law apartment below. The lower floor of the home has a third bedroom and remodeled bathroom. There is a wine closet tucked under the stairs. In the media room a tiled wet bar with wine cooler completes this perfect entertaining area. Some features added to the home that go unseen is the addition of a Q panel, updated security system, garage door opener with a battery backup and a high powered electronic Hepa air filter. Gas service was also added to the home. The top to bottom remodel created a virtual new home from its 1984 shell.

Residents of Whittier asked their local police department to label the distribution of Ku Klux Klan propaganda fliers on Sunday morning a hate crime. The fliers were packaged with a rock, a Tootsie Roll candy, and a phone number and mailing address for the Loyal White Knights of the Ku Klux Klan.
One flier vilified Republican presidential candidate Jeb Bush for his stance on immigration, another targeted Barack Obama for his race, and a third listed and statistics about "black" and "Hispanic" crime trends.
On Monday, Matt Berkelhammer of the Whittier Area Peace and Justice Coalition, flanked by representatives of the Whittier Latino Coalition and Whittier Voters Coalition at a press conference at Whittier's City Hall, stated, "We don't want the incitements contained in the fliers to be a prelude to violence in Whittier. We must act now to show that such incidents are not welcome in our community. This is serious and should be treated as a criminal matter. We demand the Whittier police approach this as a hate crime."
Louis Reyes, spokesman for the Whittier Latino Coalition, added, "We believe this is no different than a swastika being delivered to the home of a Jewish person."
Whittier Police Chief Jeff Piper said he couldn't accommodate the request, pointing out, "It's not targeted to a particular group of people or make threats upon them. I would surmise that some of these hate groups that have been around have attorneys and know how far they can push it. Regardless of that, it's unfortunate and despicable."
Similar incidents have occurred in Orange County: Klan fliers left in Old Towne Orange in November 2013; plastic bags with fliers found in Orange last July, KKK fliers distributed in Santa Ana last January, and more plastic bags with KKK material found in Fullerton last week.

In your marriage or love relationship you want to feel loved, valued, respected, cherished, safe, trusted, free, happy and important. Right? Who doesn't!
But what if you don't feel those things?
What if you feel even worse things like, disrespect, neglect, power, indifference or even contempt?
What if you think you would be happier out of your relationship than in it?
What if you have decided you have had enough and it's time to go?
What's the most important "must-do" before you leave?
Take care of your own energy.
Seriously. If you just leave without taking care of your own energy, you will as my favorite Law of Attraction teachers, Abraham-Hicks, say, "Just take yourself with you." You will attract right back into your life the same type person or circumstances. How many people do you know, or maybe even you, yourself, have met, dated, and married the very same kind of person they left!?
If you just leave, you might feel a little or a lot of relief to begin with but you will most likely be focusing on all the negative, mean, hateful, spiteful things that have added up over time about the person you left. All negative. And that is what you will re-attract. Negative. You want to shift your thoughts which shifts your energy or vibration to more positive things so that is what you will attract in someone else. Positive. New. Not what you left.
So How Do You Take Care of Your Own Energy?
1. Stay Where You Are for a Little Longer
Don't make any big decisions or take any actions… unless you are in an unsafe or abusive situation! Don't even talk about leaving with your mate yet.
2. Be Clear About What You Don't Want in This or Another Relationship
For example, I do NOT want to be disrespected.
3. Decide That You Want to Feel Better, Feel Good!
Keep thinking about what you DO want. Keep reaching for better or good feeling thoughts and then talk to your partner from this place. If you keep going back and thinking about what you don't want, you will keep feeling bad.
4. Let Go of Guilt
Guilt serves no one.
5. See Yourself and Your Soon to Be Ex-Mate as Happy, Strong and Fully Capable of Feeling Good
See them and yourself as getting on with life and love.
6. Say to Them, "You Are a Wonderful Person."
"I want us both to be happy. I want us both to be free to go after what we want in life. I know there is someone perfect for you out there, just like there is for me. I'm choosing to see you as happy because that's the way I like to see you the best!"
When you take care of your own energy, you shift your energy from negative, angry, ugly energy to more positive, kind, loving energy for both of you. Take that energy with you when you leave. You will be so much happier later on!

Youtube has been relatively cool for a long time now, from my perspective, but some of their recent changes is really starting to create quite the kerfuffle among its users. First, there was the change of Youtube comments which angered a lot of people, both content creators and users alike, since they are basically forcing everyone to have a Google+ account to participate. Then just a few days ago, their automated copyright checker has started to flag a lot of videos that seemed to affect video game uploads the most, specifically, LetsPlay and game review videos. The good part is that some game companies are seemingly taking notice and are even seemingly rushing to protect their fans' interests. Here is an article that contains more details about the situation:
YouTubes copyright cops are coming after gamers Lets Play videos
Under constant pressure and foot-stamping from copyright holders, Google has implemented a new system within YouTube that automatically flags videos that may contain copyrighted material. The trouble, as Computer and Video Games reports, is that the new system is flagging a lot of gamers Lets Play videos where they give multipart walkthroughs of popular video games overlapped with their own commentary. While such videos may technically violate gaming companies intellectual property rights, game publishers have long tolerated and even encouraged them since theyre great ways to promote games online.Also see Youtube's response in defense of their new policies:The good news for gamers who have had their videos flagged is that the gaming industry has their back. Computer and Video Games notes that big-name developers Ubisoft, Capcom, Blizzard and Deep Silver have all pledged to help their fans resolve their issues with YouTubes auto-flag algorithms and are encouraging them to contest all claims made against their videos so the companies can approve them. All the same, gamers cant be happy that their videos are constantly getting flagged for takedown and gaming companies cant be looking forward to going through thousands of videos each week to get them approved for YouTube viewing.
Tidal Wave Of YouTube Copyright Claims Underway
What do you guys think of this fiasco?Update: YouTube has responded to our request for comment, defending the recent wave of copyright claims. The company explains the event as having to do with a change to multi-channel networks (MCN).
"Nothing illustrates the incredible growth and evolution of YouTube better than the enterprise class of businesses being built on the platform today," a YouTube spokesperson told Game Informer via email. "As these networks grow, were making product and policy updates that will help them operate at scale. We are also rolling out tools that will provide more transparency for creators and networks alike. This is part of our commitment to ensure that all enterprise partners can continue to thrive and be successful on YouTube."
Furthermore, the spokesperson shared details about how these new copyright claims were issued. "We recently enabled Content ID scanning on channels identified as affiliates of MCNs," the representative told us. "This has resulted in new copyright claims for some users, based on policies set by the relevant content owners. As ever, channel owners can easily dispute Content ID claims if they believe those claims are invalid."

I've used WP Twin for years with no problems. But as client sites have grown and the server environment has changed, I started to experience incomplete backups and server issues. I think that WP Twin has reached the end of its usefulness and therefore can no longer recommend it. I've since moved client sites to UpdraftPlus and have purchased the Migrator Add-On (affiliate link) for cloning and deployment.
WP Twin is an easy and affordable way to backup a WordPress website. With one click of a button, the contents of your entire site will be cloned and stored into a downloadable file.
This blog post will show you how easy it is to backup a WordPress website using WP Twin.
We will also give you some troubleshooting tips for backing up larger sites.
After you've purchased WP Twin (affiliate link) and downloaded it to your PC, you will have the following files:
- wptwin.php: This is the program that you'll use to backup your site.
- wptwindeploy.php: This is the program that you'll use to deploy or restore your site. For the purpose of this post, we will only be concerned with wptwin.php.
How to Backup a WordPress Website Using WP Twin
- First, you will need to use FTP to upload wptwin.php to your website server using cpanel or FTP. If you aren't sure how to access your server through cpanel, I recommend FileZilla. FileZilla is a free FTP solution that you can install on your PC. If you run into problems with FTP, check out our troubleshooting guide.
- Using FTP, upload wptwin.php to the home directory of the website you wish to backup.
- Next, make sure you are logged into the WordPress admin area for that website.
- Type the URL of your website into the browser address bar and append /wptwin.php like so:http://www.yourdomain.com/wptwin.php
- The following screen will display:
- Click the "Click to Clone" button. Your backup will start.
- Once done, you will have a download link of your backed up site. This backup includes everything: files, content, and database.
- Click on the download link to save the backup to your hard drive.
- Once the download is complete, make sure you delete the clone by clicking the "Delete This Clone" button.
That's it!
I recommend you keep several versions of your backups just in case!
Troubleshooting WP-Twin Backups
I've used WP Twin for years, but have recently run into problems getting the backups to finish. As my site has grown, the environment has also changed. For example, I've added an SSL certificate and put my site under CloudFlare. I also moved to a Web Hosting Manager (WHM) account.
Since making the above changes, I've had trouble getting WP-Twin to run successfully. I've been in touch with Rapid Crush support, and they've sent me the following requirements to get WP-Twin to run:
- Must be on the Linux hosting environment (linux hosting account).
- system() and exec() PHP functions should be allowed to run on the server
- zip, unzip, mysql, mysqldump, grep, and sed have to be available commands on the server
- The UID that scripts run under must have rights to write files. (They have a test file that can confirm the UID and the commands above)
- The mySQL database user has to have FULL rights to the database
- Curl must be enabled
Still, even following the instructions above and disabling CloudFlare and caching I cannot get the backup to run. So I've recently started using UpdraftPlus for my site and larger sites that timeout on the server when using WP-Twin.
If your site is large, you may run into problems cloning your site. That's because WP Twin may time out on the server before the backup is done. This usually happens when the WordPress UPLOADS folder has lots of images and media files.
In order to work around this problem, first try to increase the max_execution_time in php.ini to 300. Make a note of the original value so you can change it back when done with your troubleshooting.
The following procedure is an advanced method for cloning your large site and restoring it to a new domain.
Backup Your Website:
- Zip up "wp_content/upload"
- Put the site under maintenance
- Disable any security plugins as they can interfere with WP Twin functionality
- Optimize the database (not required, but can shrink the database considerably)
- Move the "wp-content/upload" to another non-WordPress folder (i.e.:"public_html/temp_upload")
- Run WP Twin
- Move the images back from "public_html/temp_upload" to "wp-content/upload"
- Reactive any security plugin that was disabled in step 3
- Put the site back to live mode
- Put the max_execution_time back to what it was
Download the Files
In the following steps, you'll be downloading two zip files instead of
- Now download zip file from Step 1
- Download the WP Twin file in step 6.
Restoring the Files
And now that you've got a backup procedure in place, learn how to use WP Twin to restore your backup.
Generally, in order to restore your website, all you need to do is deploy the WP Twin backup file to your domain as explained at the above link.
However, if you followed our advanced procedure above, you'll also need to upload the images zip file to your domain and extract the files to "wp-content/upload."
In Summary
So now you know how to backup a website using WP Twin. You also learned how to troubleshoot a large site and were given a few additional steps to help you work around any server or WP Twin limitations.
Questions? Leave a comment below and I'll be happy to help you out!
Please note that you cannot use WP Twin on local installations of WordPress. I contacted Rapid Crush support and they confirmed that WP Twin isn't supported on Windows servers, Mac OS X, WAMP, XAMPP (or other Local environments), WP-MU or MultiSite configs. The necessary programs aren't there.
