Rationally Designed Nitrogen-Rich Metal–Organic Cube Material: An Efficient CO2 Adsorbent and H2 Confiner
Autores:Guillermo Calleja , J. A. Botas , Manuel Sánchez Sánchez
Grupos de investigación:Tamices Moleculares
Metal–organic frameworks (MOFs) have been postulated for years as industrially achievable materials for CO2 capture and H2 storage. However, a great leap forward their real applications is still pending. This article details the design of a MOF material, including the reasoned choices of metal ion, organic linker, and even the structural subunits, as efficient adsorbent of both CO2 and H2. In particular, it was planned (i) to raise the polarizability of the framework by using a highly N-rich organic linker and (ii) to favor the formation of nanocavities with suitable size to confine small molecules. The resultant tetrazole-imidazole-based ITF-1 material containing nanocubes certainly achieved all these aimed premises. Nevertheless, such structural and compositional distinctiveness was reflected in some noteworthy adsorption features. CO2 adsorption was highly remarkable, and it was characterized by a wide hysteresis loop along the whole studied range of pressures. H2 molecules totally filled the nanocavities under only 0.1 bar at 77 K, and at 273 K, H2 uptake became tens of times higher than expected according to their textural properties. These unique adsorption results, together with the discussed relationship between structure/composition of ITF-1 and their adsorption features, underline the importance of a tailored MOF materials for particular applications.

Roller shutters are becoming increasingly popular with homeowners. This is because they offer the option of security, but they are more attractive than other options along this line. So below is some information about rolling shutters.
Advantages of rolling shutters
One of the advantages of rolling shutters are that they offer protection from both the weather as well as burglars. With weather, they are both a barrier and a deterrent against rain, wind, hail and storms as well as brushfire embers. With burglars, they make entry through them very difficult.
These shutters also come in an array of colors, as well as materials, designs and textures. They are practical too because they are easy to open and shut so you can decide how much light to let into your home. Some of these shutters are also electrical also so you just push a button and they go up and down easily.
In addition, these shutters are simple to install along with the ease of use. There aren't any dangling cords to entangle a child or pet. Plus because of the many styles, these shutters can be used with curtains, drapes or by themselves. Then you can customize your look however you choose.
Disadvantages of rolling shutters
If you have a Victorian house, these shutters may not be a good idea. Since the shutters have a contemporary look, they wouldn't be suitable for a house that has a historical look to it.
The mechanism that moves them up and down could fail and would need to be fixed, a warranty may be a good idea. The alternative is though is to have the shutters which shut manually.
When weighing the pros and cons, it's a great method of security when you want to feel safe at home.

Zoe Grindea
The world presented by Zoe's photographs is a mythical world.
It starts somewhere in Genesis, with the primal separation of the genders, male from female,
and ends merely at the end of the world, with the final separation, those designated for heaven
from the ones designated to go to Hell. While the visual world of Zoe is characterized by the
grandiosity between genesis and apocalypse, altogether different forces strive underneath it:
intimacy, naughtiness. In this context it is impossible to ignore the fact that the sitters in
Zoe's photographs are her three kids. Zoe, a photographer and a mother, flashes on her own flesh
and blood, therefore it is not surprising that all these universal subjects are just a wrapping
to the true grain of the work all of which is intimate, most intimate.
If one has to chose one component that concentrates all of the issues sizzling under Zoe's
photographs, I believe it can be found in the flowing blond hair of Zoe's middle child – Libi.
This golden hair is a meeting point between storm and childhood serenity, between golden
paradise and death awaiting anyone trying to stretch his hand and reach its beauty: the same
death that awaited Avshalom as his hair got bounded in the branches, the same death that
awaited those that stood before Medusa's scattered hair or the same death of those betrayed
by their own desire facing the sirens seduction. There is no doubt that Zoe's photographs
bring together seduction innocent, serenity and danger, but above all, just like that golden
hair, they are, first of all, beautiful. In such a way Zoe presents the concept so often lost
in the art field of recent decades, that the heart of plastic art rests upon working with
One of the recurring themes in Zoe's work is duality. One can spot this motif in a series
of photographs of Zoe's son, which draws its inspiration from Narcissus' myth, and also in
another photograph of the same child with two feminine figures drawn in the background.
The motif is detectible also in the photographs in which Zoe's two daughters appear with a
similarity that misleads one for a moment and by doing so pulls him to back to deal with
duality, a subject that reemerges in the context of the pair of fish that comes out more than
once in thephotographs. Duality is a deep encounter between aesthetics, striving to the harmony
of symmetry residing in the living, […] Duality is a kind of absence of life since it takes
away the uniqueness from a human being, and thus his humanity. Not unintentionally is this
image so casual in the visual world of horror stories and films. In this respect, in dealing
with this motif, Zoe manages again to create the encounter of beauty and death. The motif
receives yet another layer by the fact that it is a mother photographing her own children,
her own reproduction which also has a sort of duality, gift of life and death.
In parallel one can notice the opposite motif – the division. In a piece where her son holds
the sward in such a way that it splits his face in two echoes again the inseparable connection
between beauty and symmetry and incision and death. The motif receives yet again a surprising
layer, considering the fact that the figure is the photographer's son. Some sort of Salomon
judgment that Zoe conducts within herself. Childbirth not only as multiplication and
reproduction but as self dissection as well.
Notwithstanding, despite Zoe's occupation with fateful subjects such as life and death,
the child's sward is a toy' the lights decorating these pseudo-baroque photographs are nothing
but cheap birthday party lights, ending in such a way that all mentioned grandiose contents are
squeezed into brackets. The work exteriorizes baroque esthetics but embodies the kind of
awareness and self contradiction which is, in my opinion, the major characteristic of our time.
Zoe uses the power hidden in the roll of children as models in order to enrich the complexity
of the work in relationship to words such as awareness and irony. When children are models,
the observer is aware, in a certain aspect, of the very partial and idiosyncratic understanding
of the very same models/children, of the situation in which they play a part. The gazes and
setting-ups of the children, gazes and setting-ups that are never completely played, since
playing borders in childhood are so flexible still, force more than once a context of a jest,
of a naughty act, on the sublime and allegedly "heavy" contents from which the works emerged.
As such, the malice in them is forever forgiven, the subversion in them is always innocent
and their heart always smiles.
The complexity of childish gaze looking from a photograph that was thought of and carried out
by an adult climbs to a sort of climax, in my opinion, in the photograph of both of Zoe's
daughters in which Libby appears (the older, on the right) with her fingers creating a sort
of a monocle through which she is looking at the lens, and in fact at us, the observers of
the photograph, as well. There is present,in this gesture, the full complexity of a child
who actually plays but takes part in a game too big for his capacity to grasp. A game of
observers and objects' of truth and fib, of allthe things children do not completely
understand, a game between all that can be planned in a staged photograph and all that
one can never plan – a spontaneous gesture of a child, the scattering shape of girl's
golden hair.

"Lands of Lost Borders carried me up into a state of openness and excitement I haven't felt for years. It's a modern classic."—Pico Iyer
"Lands of Lost Borders is illuminating, heart-warming, and hopeful in its suggestion that we will explore not to conquer but to connect."—Booklist (starred review)
A brilliant, fierce writer, and winner of the 2019 RBC Taylor Prize, makes her debut with this enthralling travelogue and memoir of her journey by bicycle along the Silk Road—an illuminating and thought-provoking fusion of The Places in Between, Lab Girl, and Wild that dares us to challenge the limits we place on ourselves and the natural world.
As a teenager, Kate Harris realized that the career she craved—to be an explorer, equal parts swashbuckler and metaphysician—had gone extinct. From what she could tell of the world from small-town Ontario, the likes of Marco Polo and Magellan had mapped the whole earth; there was nothing left to be discovered. Looking beyond this planet, she decided to become a scientist and go to Mars.
In between studying at Oxford and MIT, Harris set off by bicycle down the fabled Silk Road with her childhood friend Mel. Pedaling mile upon mile in some of the remotest places on earth, she realized that an explorer, in any day and age, is the kind of person who refuses to live between the lines. Forget charting maps, naming peaks: what she yearned for was the feeling of soaring completely out of bounds. The farther she traveled, the closer she came to a world as wild as she felt within.
Lands of Lost Borders, winner of the 2018 Banff Adventure Travel Award and a 2018 Nautilus Award, is the chronicle of Harris's odyssey and an exploration of the importance of breaking the boundaries we set ourselves; an examination of the stories borders tell, and the restrictions they place on nature and humanity; and a meditation on the existential need to explore—the essential longing to discover what in the universe we are doing here.
Like Rebecca Solnit and Pico Iyer, Kate Harris offers a travel account at once exuberant and reflective, wry and rapturous. Lands of Lost Borders explores the nature of limits and the wildness of the self that can never fully be mapped. Weaving adventure and philosophy with the history of science and exploration, Lands of Lost Borders celebrates our connection as humans to the natural world, and ultimately to each other—a belonging that transcends any fences or stories that may divide us.

"Beautifully rendered...Harris's talent is in her prose, as she offers breathtaking descriptions of the Silk Road, shrouded in mystery and wonder." - Publishers Weekly
"In her luminous, incisive memoir, Harris chronicles her permanent wanderlust, her twisting career path and the months she spent cycling the Silk Road with her best friend...Lyrical, brilliant and sharply observed, it is a paean to wanderlust and a call for readers to launch their own explorations." - Shelf Awareness
"Her captivating memoir will inspire readers to question their self-imposed boundaries and map out new adventures." - Real Simple
"A compelling, suspenseful, insightful and elegant travel memoir. This is one that will have you dreaming." - Minneapolis Star Tribune
"Harris' stunning and nuanced prose limns sweeping landscapes and offers engaging history lessons—all while maintaining a brilliant self-awareness and authenticity. Lands of Lost Borders is illuminating, heart-warming, and hopeful in its suggestion that we will explore not to conquer but to connect." - Booklist (starred review)
"An immersive and keenly observed debut...an uncompromising, breathless record." - New York Journal of Books
