    The race to create bigger smaller and better flexible displays now has yet another participant, but Weijia Wen and colleagues at the Hong Kong University of Science and Technology are putting a toasty twist on their iteration. The team has reportedly developed a "flexible, thermally-activated electronic display made from a mixture of metal nanoparticles and plastic," which costs far less than most similar alternatives to create and measures just 150-microns in thickness. Moreover, these units are able to change hues based on the surrounding temperatures, and while only fixed patterns are available for viewing at the moment, the crew hopes to implement an array of "thermal pixels" in the future for more dynamic opportunities. A display that warns you of an overheating machine / battery / toy -- who woulda thunk it?[Thanks, Alan]

    As if there weren't enough "almost theres" in the world of printable circuits, now we've got yet another team developing their own iteration of a printing press for electronics. The group, which includes scientists from DuPont and Organic ID, has reportedly "fabricated a printing plate used to print the source-drain level of an array of thin-film transistors," essentially solving some of the low-resolution constraints seen on prior competition. The goal is to eventually posses the ability to "print large, flexible circuits using machines similar to printing presses," and while it seems to be a ways from commercialization, initial testing and comparisons to more traditionally-created transistors have produced glowing results.[Image courtesy of HowStuffWorks]

    Two Israeli scientists may have created the catalyst for a medical revolution with their new project: a tiny, 1-millimeter-diameter robot which is capable of crawling through human veins and arteries. The bot can cling to vessel walls using small, powerful arms which protrude from a hub in its center. Manned control is accomplished by using a magnetic field outside of the body, and the robot is able to swim against the flow of blood, as well as squeeze through a variety of arterial openings. Right now the doctors don't know what the medical applications might be, though they speculate that a large number of the bots could be used to fight certain types of cancer. Other ideas on the table include using the bots to exact revenge on anyone opposing their crazy ideas.[Thanks, Ralph]

    Just days after Fujitsu tooted its own horn and suggested that it could increase hard drive capacity by 500-percent in a mere two years comes word that Toshiba coincidentally has a similarly grandiose claim. Aside from the obvious leapfrog game that's being played here, Tosh has apparently been working hand-in-hand with Tohoku University to develop "a phenomenon" dubbed Nanocontact Magnetic Resistance, or NC-MR, in which an "enormous difference in magnetoresistance is achieved when two magnetic materials are situated close together and connected by a contact point that narrows to around 1-nanometer." Put simply, the prototype NC-MR structure is twice as large as today's read heads, and elements based on the NC-MR structure would have a "lower resistance than existing TMR elements, enabling the read heads to be miniaturized and still operate quickly." Of course, these sensational claims have yet to make it beyond the drawing board, and while you may be anxious to get one of these in your rig, you'll be waiting about five years or so if things continue as planned.

    It's been a tick since we've heard details on an emerging battery technology that promises to trounce even the best products currently available, but researchers at the Department of Energy's Argonne National Laboratory have reportedly developed yet another approach to boosting Li-ion capacity and stability. The technology is "based on a new material for the positive electrode made of a unique nano-crystalline, layered-composite structure," which allows an active components to provide for charge storage while residing in an inactive components which assists in keeping the risk of explosion low. Current claims are putting the capacity right around "double that of conventional Li-ion cells," and it could be used in a variety of wares from "mobiles, laptops, pacemakers and defibrillators, or even hybrid / electric vehicles." Unfortunately, there was no timetable as to when scientists expected said technology to actually be available commercially, so until then, we'll consider this yet another promise on pause.[Via I4U]

  • Cornell designer concocts garb that prevents colds, shuns pollution

    We've seen sensor-laden, iPod-friendly, and electroluminescent garb in years past, but a crafty design student over at Cornell University wasn't satisfied with stopping there. Olivia Ong is hoping to get her career in fashion off to a very safe start, as her functional clothing lines include "a garment that can prevent colds and flu and never needs washing," and if that wasn't fresh enough, she's also conjured up another that "destroys harmful gases and protects the wearer from smog and air pollution." The prototype Glitterati garb was showcased at the school's Design League fashion show, and both articles contained "cotton fabrics coated with nanoparticles" that give them the unique qualities. No word on whether or not we can expect such protective (albeit stylish) threads to hit the strip anytime soon, but considering that "one square yard of nano-treated cotton would run you about $10,000," we doubt us common folk would be selling off assets to take it home anyway.

    Someone should seriously tell IBM's research and development team to take a much-deserved vacation, as these folks have been cranking out the goods at an alarming rate of late. Most recently, the company has announced the "world's first application of self assembly used to create a vacuum around nanowires for next-generation microprocessors," which just so happens to mimic the natural pattern-creating process that forms seashells, snowflakes, and enamel on teeth. Essentially, the process forms "trillions of holes to create insulating vacuums around the miles of nano-scale wires packed next to each other inside each computer chip," which should aid electrical current in flowing around 35-percent faster while it eats up about 15-percent less energy. This newfangled approach to insulation, dubbed airgaps, creates vacuums that enable the substantial boost in speed, and the self assembling process is reportedly "already integrated" into IBM's manufacturing line in New York. The chips will initially be used in the firm's server lineup sometime near 2009, and shortly thereafter, we can expect IBM to start cranking these out for other companies that rely on its CPUs.[Via BBC, thanks Josh]

    While the school of the Ramblin' Wreck may be best known for its barrage of engineering graduates, the university has been on quite the medical trip of late, as researchers have reportedly developed a nanometer-scale generator after already cranking out nanowires that monitor your blood pressure. The aptly-named nanogenerators can produce "continuous direct-current electricity by harvesting mechanical energy from such environmental sources as ultrasonic waves, mechanical vibration or blood flow," which translates into easy energy for implanted and worn medical gadgetry of the future. Interestingly, the project was funded by the likes of the National Science Foundation and our pals at DARPA, and while this invention may not quite match up with wireless charging (hey, we're scared of hospitals), the concept is novel nonetheless. So if you were hoping that dreams of implanted analysis of your vitals would suddenly cease, things aren't looking up for you.[Via MedGadget]

  • Morpho Towers: ferrofluid sculptures that groove to the music

    There's just something irresistible about random objects that get down to surrounding beats, and the Morpho Towers: Two Standing Spirals installation is quite the eye-catcher indeed. The pair of ferrofluid sculptures were deigned to stand in a platter of ferrofluid and move "synthetically to music," which translates into a magnetic field being generated by sound and creating autonomous art. Subsequently, the towers react by attracting "spikes of ferrofluid" from the bottom-up, which can mold itself and transform into a variety of stunning shapes. The spikes themselves are designed to "rotate around the edge of the spiral cone, becoming large or small depending on the strength of the magnetic field," and by utilizing time series metadata ingrained in the music, the designers can create (and control) more dramatic scenes on the towers' sides. So if you're interested in what a magnetic Christmas tree might look like, be sure to take a peek after the jump for the artwork in motion.[Via SciFiTech]

    You've got plenty of options when it comes to healing your own body, but patching up your domicile usually requires days of back-breaking labor and gobs of cash to boot. Thankfully, that awful process could be nearing its end, as a £9.5 million ($18.64 million) European Union-funded project sets out to develop self-healing walls for your average home. The idea is to develop "special walls for the house that contain nano polymer particles, which will turn into a liquid when squeezed under pressure, flow into the cracks, and then harden to form a solid material." The technology would prove quite useful in areas where earthquakes are prominent, and in an effort to test things out before shoving it out to contractors everywhere, a swank villa is being erected on a Greece mountainside to collect information. The house's walls will be built from "novel load bearing steel frames and high-strength gypsum board," but more importantly, they will contain a smorgasbord of wireless sensors and RFID tags meant to collect, store, and disseminate critical data regarding "any stresses and vibrations, temperature, humidity, and gas levels." Now, who's the lucky lad(s) that get to call this their home research dwelling?[Via Physorg]

    We've already seen molecular elevators, keypad locks, and even spiders, but a team of scientists at the University of Tokyo have now further expanded our pint-sized toolkit, crafting a pair of molecular scissors for those hard to reach places. Apparently, the scientists used rings of carbon and hydrogen for the blades, with a "chiral ferrocene" molecule supplying the pivot point, and couple of "phenylene groups" acting as handles -- all of which adds up to to a mere three nanometers in length. To manipulate the scissors, the scientists simply alternate between shining visible light and UV rays to open and close 'em. According to LiveScience, the team's now working on a slightly larger pair of clippers that can be operated remotely, potentially for use inside the human body -- which is only a somewhat less scary prospect than a swarm of nanobots being let loose for a little autonomous repair work.

  • Judge favors Nano-Proprietary in Canon licensing quandary

    We all had high hopes that SED TVs wouldn't become another case of "what could have been," but unfortunately for everyone, things aren't looking too bright right about now. Last we heard, Canon was reportedly all set to buy out Toshiba's display stake, theoretically squashing Nano-Proprietary's claim that licensing agreements would be breached if Tosh remained in the mix, but it seems that things just can't be so easy. A federal judge has now ruled that Canon "violated its agreement with Texas-based Nano-Proprietary by forming a joint television venture with Toshiba," and while "damages still need to be determined," it's fairly clear who will come out the victor in this scenario. Still, this just appears to be yet another snag in the development of new nanotube sets, and while we should all just be used to it by now, that glimmer of hope that Canon and Nano-Proprietary "could now develop a new licensing agreement" is still (currently) alive.

    It's fairly reassuring that if those rollable, water-powered, paper, and ultracapacitor-based battery ideas don't exactly pan out, we've got yet another idea coming out of MIT that just might gain traction. Apparently, scientists at the university are working on self-assembling Li-ion cells when not thinking about what witty remark they'll plaster on their own spacecraft, and it seems that Yet-Ming Chiang and his colleagues have selected electrode and electrolyte materials that, when combined, "organize themselves into the structure of a working battery." By measuring various forces with "ultraprecise atomic-force microscope probes," the researchers were able to choose materials with just the right combination of attractive and repulsive forces, essentially creating a perfect environment for batteries that could build themselves. Additionally, a current prototype has displayed the ability to be discharged and recharged "multiple times," and while commercial uses aren't nailed down just yet, the backers are already envisioning how the technology could be used in minuscule devices where standard cells won't exactly fit in. Let's just hope this stuff doesn't cause too much friction whilst building itself up, eh?[Via TheRawFeed]

  • Edinburgh scientists craft microscopic nanomachines

    There's apparently a good bit of conflict at the University of Edinburgh, as we've got one esteemed fellow claiming that nanotech products are potentially dangerous, and now we've got a professor of chemistry insinuating that his nanomachines can change the world. Regardless of their personal differences, David Leigh has borrowed an idea from 1867 in crafting "a minuscule motor that could lead to the creation of microscopic nanomachines," and while he credits the "Maxwell's Demon" as its inspiration, he hopes these plans will actually lead to something substantial. The bantam motor is entirely solar-powered, and has been "devised to trap molecules as they move in a certain direction under their natural motion." Preliminary tests have shown a nanomachine moving a drop of water uphill by using molecular force, which gives researchers hope that this discovery will allow these diminutive machines to "do things that are much closer to what biological machines do." Of course, even Mr. Leigh admits that predicting just how this can or will effect society is difficult, but considering that he's aiming to to bring things that "could happen in a Harry Potter film" to fruition, we won't count him out just yet.

  • Researchers condense entire image into single photon

    A team of researchers has managed to find a way to store a large amount of data in a single photon of light. Although the first stored item -- an image of the characters "UR" -- implies that the inventor was a 13 year old girl dealing with an extremely low text messaging limit, the image was in fact intended to signify the institution which developed the technology, the University of Rochester (either that or it's the shortest example of the "UR IN MY ... " meme that we've seen in the while.) Apparently the system works because "instead of storing ones and zeros" (a la binary code), the team has figured out how to store an entire image in a single photon, which sounds sort of impossible to us. Funny, because that's exactly what John Howell, the leader of the team said about the system. One of the key components of the process is the particle-wave duality nature of light: by firing a single photon of light through a stencil -- we presume one heckuva small one -- the wave carries a shadow of the image along with it at a very high signal-to-noise ratio, even with low light levels. The light is then slowed down in a cell of cesium gas, where it is compressed to 1 percent of its original length. This is where the storage aspect of the device comes in, as the researchers hope to be able to delay a single photon almost permanently, resulting in a device that can store "incredible amounts of information in just a few photons": an enticing thought for a world currently satisfied with a maximum of 1TB hard drives based on physical platters. A pity then that the world is completely distracted by the potential for "Photon on photons" jokes that this throws into the ring.

    If you're the type who rocks latex gloves everywhere you go, or you're just tired of toting around that messy liquid hand sanitizer, Hammacher Schlemmer has your solution. Posing as a flip-phone wannabe, this handheld germ-eliminating light reportedly eradicates "99.99-percent of E-Coli, staphylococcus, salmonella, and germs that cause the flu and the common cold." Aside from resembling a bevy of Nokia handsets, the device purportedly utilizes "UV-C light and nanotechnology" in order to "disinfect workplace keyboards or telephones (or mice), as well as items in the home that sustain germ vitality such as toothbrushes and cutting boards." Notably, it must be held just so above the germ-infested area in order to sterilize it, but an internal timer signals when the process is complete. So while we aren't apt to load down our knapsacks anymore with something so petty, the highly susceptible out there can get their own portable germ-slaying handheld now for $79.95.[Via Slashgear]

  • Israel adding to global animalbot army with "bionic hornets"

    Israel thinks that the best way to think big is to think small. Reuters reports that the country will be researching the use of nanotechnology to fight militants within its borders over the next few years. Among the proposed projects are a set of "super gloves" that would give the wearer the power of a "bionic man," as well as tiny sensors to find suicide bombers. However, our favorite is a "bionic hornet" -- no bigger than a real hornet -- which would have the ability to "chase, photograph and kill its targets." While the bionic hornet hasn't actually been built yet, Deputy Prime Minister Shimon Peres said that prototypes for the new weapons could be expected by 2010. Americans, don't worry, we've already got our own insect cyborgs, attack dolphins, spy turtles and remote-controlled sharks underway, which should be ready within three years to counter any sissy hornets, bionic or otherwise.

    It's not often we see the latest in nanotech coming out of French fashion houses, but Avelana and Roudière have gone and thrown expectations for a loop, announcing the Klimeo thermo-regulating fabric. Supposedly, the nano-enhanced fabric will automatically adjust to suit your environs, keeping you warm when its chilly and cool when the temperature rises. Just as importantly, it also won't cramp your style, seamlessly blending into a variety of different fabrics suitable for everyday wear. The magic ingredient is, of course, nanotechnology -- specifically, microcapsules grafted onto the fabric that change from a solid state when it's cold to a liquid state when it's warm. We somehow doubt that'll be enough to keep us nice and toasty in nothing but jeans and a tee come February, but that won't stop us from trying.[Via Gizmag]

  • NanoNuno: the water-repelling umbrella

    So we've got umbrellas that are WiFi-enabled, iPod controllers, and wannabe meteorologists, but how about one that just keeps itself (and you) dry? Some crafty blokes in Britain are getting back to basics with the NanoNuno umbrella, which utilizes nanotechnology to create a canopy of minuscule fibers that water, dirt, and a host of other elements out there have a hard time adhering to. The idea was supposedly borrowed from the "natural phenomenon" witnessed on the Lotus leaf, which sports a similar, sleek surface that water simply rolls off. Since moisture can (presumably) not penetrate the surface, the company claims a simple shake or two will return the umbrella to the arid state it was in before braving the weather, but priced at £49.95 ($94), this probably only appeals to those stuck on the windward side of the island (or Seattle).[Via PopGadget]

    You know how your mother told you to wipe your mouth after you eat? Well, if you're afraid that your eating area is infested with biohazards, you may find yourself wiping a lot more in the near future. Researchers at Cornell University announced last week that a "biodegradable absorbent wipe" is in the works, which would signal -- possibly through a color change -- if the surface it touches is infested with bacteria, viruses, or other "dangerous substances" by employing embedded nanofibers. Prof. Margaret Frey of Cornell says that this napkin is still "a few years away" from being available to the public -- so in the meantime, you may still want to use that e-nose to detect bugs that infect your bagged spinach food supply.[Via Sci Fi Tech]
