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. Related:  Technology IITechnologies

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. It took him 14 years to find a practical conceptualization that would work to advance the storage industry; 3D Volume Holographic Optical Storage Nanotechnology, for which Michael holds the patents. • Join PhysOrg.com on Facebook! This invention and patents on a technique for changing matter at the molecular level is one of the World's only new enabling technologies, having many hundreds of electro-optic applications. “In 1974 I was making 5 Megabyte disk packs - the biggest at that time in the world.

5 Bizarre Killing Sprees that Never Got Solved When you think about unsolved murder sprees, it’s usually cases like Jack the Ripper or The Zodiac Killer—the ones with movies and dozens of books about them. But they’re not the only ones. They’re not even the weirdest ones. Here are five bizarre killing sprees that never got solved… The Chicago Tylenol Murders In the fall of 1982, people with headaches and menstrual cramps all over Chicago were fucked if they reached for the Tylenol bottle. The same day (what timing!) Chicago police informed Johnson & Johnson, who immediately put on the skids and issued a mass recall of Tylenol throughout the area . Even with the recalls, though, it was too late for three other people who ingested the tainted pills. No one was ever caught and no motives ever uncovered, but one dumbass, a con-man/accountant (which is either the weirdest or best job combination we’ve ever heard of) by the name of James W. Bible John The 60s were a time of peace, free love and deranged killings in Glasgow, Scotland.

Smartphone Biosensor Devised to Detect Toxins, Pathogens | Science Business 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. The technician inserts the slide with the specimen sample into the cradle and the reflected light spectrum is measured. Read more:

Artificial Intelligence Is Coming to the iPhone, And It's Going to Change Everything Let me start off by saying this: Your phone is not suddenly going to gain sentience and become Skynet. However, your phone is about to become a whole lot smarter, thanks to Apple and its new artificial intelligence Assistant. The hype surrounding Tuesday's Apple iPhone event is at an all-time high. The real star of Tuesday's show will not be the hardware, though. Assistant is the successor to Siri, the iPhone app that helped users with their daily tasks with natural language voice commands. The technology that powered Siri was born from SRI's CALO project, the largest artificial intelligence project in U.S. history. Two months after its launch, Apple acquired Siri for more than $200 million. What Assistant Will Do On Tuesday, Siri will be reborn as Assistant. Say you're in a new city and you're really craving Chinese. Instead of searching for the taxi company's number, Assistant will find it for you. The key though is that Assistant will learn. "This is real AI with real market use.

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. Still, Tor is best known as a niche tool for hackers, whistleblowers, criminals, activists, or folks with otherwise something to hide. So goes the thinking behind Safeplug, a new hardware adapter that basically puts Tor in a box. The adapter comes from hardware company Pogoplug, which announced its new product yesterday and hopes it will bring Tor to the mass market by offering more consumer-friendly access. Sure, more people using Tor would be great. Nor is the adapter necessarily easier to use than the downloadable Tor browser bundle.

$1.6 million just bought the world’s most expensive dog. Big Splash, or “Hong Dong” in Chinese, is an 11-month-old Red Tibetan Mastiff. He already stands nearly three-feet-high at the shoulder and weighs more than 180lbs. He was recently purchased by an unidentified Chinese coal baron. justifiable existence How Do You Create A Culture Of Innovation? This is the third part in a series by Scott Anthony, author of The Little Black Book Of Innovation. It sounds so seductive: a “culture of innovation.” The three words immediately conjure up images of innovation savants like 3M, Pixar, Apple, and Google--the sorts of places where innovation isn’t an unnatural act, but part of the very fabric of a company. While culture is a complicated cocktail, four ingredients propel an organization forward: the right people, appropriate rewards and incentives, a common language, and leadership role-modeling. The Innovator’s DNA Has Four Components If you ask most people what makes a great innovator, the most common response is innate gifts from parents or a higher power. At the core is what the professors call “associational thinking.” Questioning: Asking probing questions that impose or remove constraints. Most organizations have people who follow these behaviors--even if they aren’t immediately obvious to senior leadership. Then it dawned on me.
