A Nanotech Skylight That Looks Just Like the Sun Shining Overhead

Posted by in category: nanotechnology

By  — Wired

As portions of the US are battered by snowstorms and shrouded beneath gray skies, a European startup is developing a light fixture that mimics the sun.

Each CoeLux fixture models the sunlight of a specific locale, be it the cool color and strong shadows of equatorial countries, the even glow of Mediterranean sunlight, or the slightly dimmer and warmer, but more striking patterns found along the Arctic Circle.

CoeLux fixtures use traditional LEDs, calibrated to the same wavelengths as the sun. However, accurately recreating sunlight also requires mimicking subtle variations caused by the atmosphere, which varies in thickness and composition depending upon where you are on earth. CoeLux uses a milimeters-thick layer of plastic, peppered with nanoparticles, that does essentially the same thing in your living room. CoeLux’s inventor, Professor Paolo Di Trapani hasn’t made any disclosures about how the nanotechnology works in practice, but an impressive list of peer-reviewed publications, industry awards, and testimonials from customers provide comfort that these devices actually work as advertised.

“No, no it’s not science fiction; it’s already happening,” said Ido Bachelet to a somewhat incredulous audience member at a London event late last year. Bachelet, previously of Harvard’s Wyss Institute and faculty member at Israel’s Bar-Ilan University, is a leading figure in the field of DNA nanotechnology.

In a brief talk, Bachelet said DNA nanobots will soon be tried in a critically ill leukemia patient. The patient, who has been given roughly six months to live, will receive an injection of DNA nanobots designed to interact with and destroy leukemia cells—while causing virtually zero collateral damage in healthy tissue.

Quoted: “Legendary cyberculture icon (and iconoclast) R.U. Sirius and Jay Cornell have written a delicious funcyclopedia of the Singularity, transhumanism, and radical futurism, just published on January 1.” And: “The book, “Transcendence – The Disinformation Encyclopedia of Transhumanism and the Singularity,” is a collection of alphabetically-ordered short chapters about artificial intelligence, cognitive science, genomics, information technology, nanotechnology, neuroscience, space exploration, synthetic biology, robotics, and virtual worlds. Entries range from Cloning and Cyborg Feminism to Designer Babies and Memory-Editing Drugs.” And: “If you are young and don’t remember the 1980s you should know that, before Wired magazine, the cyberculture magazine Mondo 2000 edited by R.U. Sirius covered dangerous hacking, new media and cyberpunk topics such as virtual reality and smart drugs, with an anarchic and subversive slant. As it often happens the more sedate Wired, a watered-down later version of Mondo 2000, was much more successful and went mainstream.”

Quoted: “If you understand the core innovations around the blockchain idea, you’ll realize that the technology concept behind it is similar to that of a database, except that the way you interact with that database is very different.

The blockchain concept represents a paradigm shift in how software engineers will write software applications in the future, and it is one of the key concepts behind the Bitcoin revolution that need to be well understood. In this post, I’d like to explain 5 of these concepts, and how they interrelate to one another in the context of this new computing paradigm that is unravelling in front of us. They are: the blockchain, decentralized consensus, trusted computing, smart contracts and proof of work / stake. This computing paradigm is important, because it is a catalyst for the creation of decentralized applications, a next-step evolution from distributed computing architectural constructs.

‘Nano-pixels’ promise thin, flexible, high resolution displays

Posted by in category: nanotechnology

Univrsity of Oxford

A collection of still images drawn with the technology

A team led by Oxford University scientists explored the link between the electrical and optical properties of phase change materials (materials that can change from an amorphous to a crystalline state). They found that by sandwiching a seven nanometre thick layer of a phase change material (GST) between two layers of a transparent electrode they could use a tiny current to ‘draw’ images within the sandwich ‘stack’.

Initially still images were created using an atomic force microscope but the team went on to demonstrate that such tiny ‘stacks’ can be turned into prototype pixel-like devices. These ‘nano-pixels’ – just 300 by 300 nanometres in size – can be electrically switched ‘on and off’ at will, creating the coloured dots that would form the building blocks of an extremely high-resolution display technology.

Robots come in all shapes and sizes—some are mechanical, and some aren’t. Last year, a team of scientists from the University of Illinois at Urbana-Champaign made a seven-millimeter-long 3D printed robot powered by the heart cells of a rat.

The device, made of 3D printed hydrogel—a water-based, biologically compatible gel—had two feet, one bigger than the other. The smaller, longer foot was coated in heart cells. Each time the cells contracted, the robot would crawl forward a few millimeters.

UK nanotechnology company, Surrey NanoSystems, has created what they say is the darkest material known to man. Vantablack consists of a dense forest of carbon nanotubes—single atom carbon tubes 10,000 times thinner than a human hair—that drinks in 99.96% of all incoming radiation.

First announced last year, the material is a deep, featureless black even when folded and scrunched. “You expect to see the hills and all you can see…it’s like black, like a hole, like there’s nothing there. It just looks so strange,” Ben Jensen, the firm’s chief technical officer, told the Independent.

What to make of the film ‘Transcendence’? Show it in classrooms.

transcendenceI recently saw the film Transcendence with a close friend. If you can get beyond Johnny Depp’s siliconised mugging of Marlon Brando and Rebecca Hall’s waddling through corridors of quantum computers, Transcendence provides much to think about. Even though Christopher Nolan of Inception fame was involved in the film’s production, the pyrotechnics are relatively subdued – at least by today’s standards. While this fact alone seems to have disappointed some viewers, it nevertheless enables you to focus on the dialogue and plot. The film is never boring, even though nothing about it is particularly brilliant. However, the film stays with you, and that’s a good sign. Mark Kermode at the Guardian was one of the few reviewers who did the film justice.

The main character, played by Depp, is ‘Will Caster’ (aka Ray Kurzweil, but perhaps also an allusion to Hans Castorp in Thomas Mann’s The Magic Mountain). Caster is an artificial intelligence researcher based at Berkeley who, with his wife Evelyn Caster (played by Hall), are trying to devise an algorithm capable of integrating all of earth’s knowledge to solve all of its its problems. (Caster calls this ‘transcendence’ but admits in the film that he means ‘singularity’.) They are part of a network of researchers doing similar things. Although British actors like Hall and the key colleague Paul Bettany (sporting a strange Euro-English accent) are main players in this film, the film itself appears to transpire entirely within the borders of the United States. This is a bit curious, since a running assumption of the film is that if you suspect a malevolent consciousness uploaded to the internet, then you should shut the whole thing down. But in this film at least, ‘the whole thing’ is limited to American cyberspace.

Before turning to two more general issues concerning the film, which I believe may have led both critics and viewers to leave unsatisfied, let me draw attention to a couple of nice touches. First, the leader of the ‘Revolutionary Independence from Technology’ (RIFT), whose actions propel the film’s plot, explains that she used to be an advanced AI researcher who defected upon witnessing the endless screams of a Rhesus monkey while its entire brain was being digitally uploaded. Once I suspended my disbelief in the occurrence of such an event, I appreciate it as a clever plot device for showing how one might quickly convert from being radically pro– to anti-AI, perhaps presaging future real-world targets for animal rights activists. Second, I liked the way in which quantum computing was highlighted and represented in the film. Again, what we see is entirely speculative, yet it highlights the promise that one day it may be possible to read nature as pure information that can be assembled according to need to produce what one wants, thereby rendering our nanotechnology capacities virtually limitless. 3D printing may be seen as a toy version of this dream.

Now on to the two more general issues, which viewers might find as faults, but I think are better treated as what the Greeks called aporias (i.e. open questions):

Flowing salt water over graphene generates electricity

Posted by in categories: energy, nanotechnology

Yogi Patel - ArsTechnica

Hydroelectricity is one of the oldest techniques for generating electrical power, with over 150 countries using it as a source for renewable energy. Hydroelectric generators only work efficiently at large scales, though—scales large enough to interrupt river flow and possibly harm local ecosystems. And getting this sort of generation down to where it can power small devices isn’t realistic.

In recent years, scientists have investigated generating electrical power using nano-structures. In particular, they have looked at generating electricity when ionic fluids—a liquid with charged ions in it—are pushed through a system with a pressure gradient. However, the ability to harvest the generated electricity has been limited because it requires a pressure gradient to drive ionic fluid through a small tube. But scientists have now found that dragging small droplets of salt water on strips of graphene generates electricity without the need for pressure gradients.
