Nanowire battery can hold 10 times the charge of existing lithium-ion battery

Nanowire battery can hold 10 times the charge of existing lithium-ion battery
Stanford Report, December 18, 2007 Courtesy Nature Nanotechnology Photos taken by a scanning electron microscope of silicon nanowires before (left) and after (right) absorbing lithium. Both photos were taken at the same magnification. The work is described in “High-performance lithium battery anodes using silicon nanowires,” published online Dec. 16 in Nature Nanotechnology. Stanford researchers have found a way to use silicon nanowires to reinvent the rechargeable lithium-ion batteries that power laptops, iPods, video cameras, cell phones, and countless other devices. The new technology, developed through research led by Yi Cui, assistant professor of materials science and engineering, produces 10 times the amount of electricity of existing lithium-ion, known as Li-ion, batteries. "It's not a small improvement," Cui said. The greatly expanded storage capacity could make Li-ion batteries attractive to electric car manufacturers. Cui's battery gets around this problem with nanotechnology.

Through a glass, clearly One of the most instantly recognizable features of glass is the way it reflects light. But a new way of creating surface textures on glass, developed by researchers at MIT, virtually eliminates reflections, producing glass that is almost unrecognizable because of its absence of glare — and whose surface causes water droplets to bounce right off, like tiny rubber balls. The new “multifunctional” glass, based on surface nanotextures that produce an array of conical features, is self-cleaning and resists fogging and glare, the researchers say. Ultimately, they hope it can be made using an inexpensive manufacturing process that could be applied to optical devices, the screens of smartphones and televisions, solar panels, car windshields and even windows in buildings. Photovoltaic panels, Park explains, can lose as much as 40 percent of their efficiency within six months as dust and dirt accumulate on their surfaces.

Breakthrough Nanotechnology Will Bring 100 Terabyte 3.5-inch Digital Data... Have you ever dream of 100 terabyte of data per 3.5-inch disk? New patented innovation nanotechnology from Michael E. Thomas, president of Colossal Storage Corporation, makes it real. Michael invented and patented the world's first and only concept for non-contact UV photon induced electric field poling of ferroelectric non-linear photonic bandgap crystals, which offers the possibility of controlling and manipulating light within a UV/Deep Blue frequency of 1 nm to 400 nm. THE COLORS OF TWILIGHT AND SUNSET - Stephen F. Corfidi Everyone at one time or another has marveled at the beautiful red and orange colors of a sunrise or sunset. Although colorful sunrises and sunsets can be seen anywhere, certain parts of the world are especially famous for their twilight hues. The deserts and tropics quickly come to mind. Indeed, it is a rare issue of Arizona Highways that does not include at least one sunset view, and one could amass a respectable collection of Caribbean or Hawaiian sunset postcards in just one trip. Eye-catching sunrises and sunsets also seem to favor certain times of the year.

The Robopocalypse Cometh: IBM's Cyberbrain Smart as a Cat, Getting Smarter If the Matrix or I, Robot's view of artificial intelligence sent chilly shivers down your spine, then prepare for frostbite: IBM's artificial brain is now as smart as a cat--just a stop or two down the line from human powers. Speaking at the SC09 high-performance computing conference this week, IBM representatives from the cognitive computing team will be unveiling all the technical details behind their successes with large-scale cortical simulation and brain-like emulation. But it boils down quite neatly to news that the team has, for the first time, performed an in-computer simulation of a brain's workings at a near-instantaneous speed. The magic is all done in software, with particularly clever program elements that emulate the biochemical and electrical activity of neurons and synapses in real flesh-and-blood brains. Which is where the other bit of IBM's research comes in. Making cyberbrains more like real human ones means better understanding how our brains work.

Smartphone Biosensor Devised to Detect Toxins, Pathogens Biosensor smartphone and cradle (Brian Cunningham, University of Illinois) Engineers at University of Illinois in Urbana created a system harnessing an iPhone’s camera to turn the phone into a biosensor that can detect proteins, bacteria, viruses, and toxins. The team led by engineering professor and entrepreneur Brian Cunningham published its findings in a recent online issue of the journal Lab on a Chip (paid subscription required). The biosensor is based on the ability of photonic crystals to alter the frequency of light, which are then captured by the smartphone’s camera. The materials in a photonic crystal block certain wavelengths, creating a gap in the wave bands. These crystals, and their corresponding band gaps, can be structured to control light energy in predictable ways, analogous to integrated circuits controlling the flow of electrons.

Walking cactus discovered in China Fossils of a 10-legged wormy creature that lived 520 million years ago may fill an important gap in the history of the evolution of insects, spiders and crustaceans. Skip to next paragraph Subscribe Today to the Monitor Click Here for your FREE 30 DAYS ofThe Christian Science MonitorWeekly Digital Edition The so-called walking cactus belongs to a group of extinct worm-like creatures called lobopodians that are thought to have given rise to arthropods. Spiders and other arthropods have segmented bodies and jointed limbs covered in a hardened shell. 3D holograms enter the fourth dimension - tech - 03 November 2010 Video: Holograms go 4D Holography has just gained a fourth dimension, bringing the prospect of Star Wars-style holographic telepresence into the real world. Ever since Emmett Leith and Juris Upatnieks made the first laser holograms in 1963, holography has been the future of three-dimensional imaging. Once created, a hologram can be illuminated to create a pattern of light waves that replicates the light reflected by the original object, generating a 3D image without the need for special glasses. As such, holography seems an ideal medium for three-dimensional telepresence, like the famous "hologram" of Princess Leia in the first Star Wars movie. During its 2008 presidential election night coverage, CNN's coverage used what appeared to be holographic technology, with anchor Wolf Blitzer talking face-to-face with a virtual 3D correspondent, Jessica Yellin – but the impressive visuals were added to the camera feed rather than being projected live onto the studio floor.

The Anonymous Tor Network Now Comes in a Box Photo via Flickr I have the Tor browser running on my computer, and it took me about two minutes to download. Once you're surfing through the network there are plenty of daunting technical options to dig into, but accessing the onion network for basic, everyday web use was as easy as clicking download, opening the program, and then struggling to remember all my no-longer-stored passwords.

An Interactive Infographic Maps The Future Of Emerging Technology Can speculation about the future of technology serve as a measuring stick for what we create today? That’s the idea behind Envisioning Technology's massive infographic (PDF), which maps the future of emerging technologies on a loose timeline between now and 2040. Click to enlarge.

How To Turn A Laser Into A Tractor Beam A photon has a small momentum which it can impart to anything it hits, as Arthur Compton and Peter Lebedev discovered at the beginning of the last century. We now know that photons can be used to push anything from electrons to solar sails. Today, Jun Chen from Fudan University in China and a few pals demonstrate the counterintuitive result that photons can pull things too. In other words, they’ve worked out how to generate a backward pulling force from a forward propagating beam.
