Scientists Seek To Create Inorganic Life. Antimagnets That Nullify Magnetic Fields. Nanotechnology pushes battery life to eternity. (PhysOrg.com) -- A simple tap from your finger may be enough to charge your portable device thanks to a discovery made at RMIT University and Australian National University.
In a crucial step towards the development of self-powering portable electronics, researchers at RMIT University in Melbourne have for the first time characterised the ability of piezoelectric thin films to turn mechanical pressure into electricity. The pioneering result is published in the 21 June Issue of the leading materials science journal, Advanced Functional Materials. Lead co-author Dr Madhu Bhaskaran said the research combined the potential of piezoelectrics - materials capable of converting pressure into electrical energy - and the cornerstone of microchip manufacturing, thin film technology.

Scientists have discovered a method to control the gas-phase selective catalytic combustion of methane, so finely that if done at room temperature the reaction produces ethylene, while at lower temperatures it yields formaldehyde.
Video: Magnetic Gels That Swim, Shimmy, and 'Walk' DNA nanoforms: Miniature architectural forms. Miniature architectural forms -- some no larger than viruses -- have been constructed through a revolutionary technique known as DNA origami.
Now, Hao Yan, Yan Liu and their colleagues at Arizona State University's Biodesign Institute have expanded the capability of this method to construct arbitrary, two and three-dimensional shapes, mimicking those commonly found in nature. Such diminutive forms may ultimately find their way into a wide array of devices, from ultra-tiny computing components to nanomedical sentries used to target and destroy aberrant cells or deliver therapeutics at the cellular or even molecular level. Graphene. A team of researchers from the University of Arizona and Rensselaer Polytechnic Institute have increased the toughness of ceramic composites by using graphene reinforcements that enable new fracture resistance mechanisms in the ceramic.
The research, lead by Assistant Professor Erica L. Corral from the Materials Science and Engineering Department at the University of Arizona in Tucson, and Professor Nikhil Koratkar from the Department of Mechanical, Aerospace and Nuclear Engineering at Rensselaer Polytechnic Institute in Troy, New York, was recently published in ACS Nano, the monthly journal of the American Chemical Society. New spin on graphene makes it magnetic. A team led by Professor Andre Geim, a recipient of the 2010 Nobel Prize for graphene, can now show that electric current -- a flow of electrons -- can magnetise graphene.
The results, reported in Science, could be a potentially huge breakthrough in the field of spintronics. Spintronics is a group of emerging technologies that exploit the intrinsic spin of the electron, in addition to its fundamental electric charge that is exploited in microelectronics. Billions of spintronics devices such as sensors and memories are already being produced. Every hard disk drive has a magnetic sensor that uses a flow of spins, and magnetic random access memory (MRAM) chips are becoming increasingly popular. New way to control magnetic properties of graphene discovered. University of Maryland researchers have discovered a way to control magnetic properties of graphene that could lead to powerful new applications in magnetic storage and magnetic random access memory.
The finding by a team of Maryland researchers, led by Physics Professor Michael S. Fuhrer of the UMD Center for Nanophysics and Advanced Materials is the latest of many amazing properties discovered for graphene. What the Heck is Three-Phase Power (and how can you get some)? I recently moved my shop, and in addition to the big issues, from forklift rental to sleep deprivation, we also had to deal with things like three-phase power, a variation of power delivery often used for big equipment.
The old shop had it and the new shop doesn't. So what the heck is three-phase power and how can you convert machinery to go from the more common single-phase to three-phase and vice versa? Read on. Unprecedented Cosmic Explosion Spawns an Intergalactic Mystery. A mystery is unfolding out there in the cosmos, and NASA's Swift, Hubble Space Telescope, and Chandra X-Ray Observatory are teaming up to solve the case. But while researchers have pieced together some of the pieces of the puzzle over the last week, the huge, high-energy blast continues to brighten and fade, making it the brightest, longest-lasting such burst of energy researchers have ever seen. It all started when Swift's Burst Alert Telescope picked up a powerful gamma-ray burst on March 28, at which point it notified scientists the world over. "Einstein's Pedometer" App Measures How Special Relativity Affects Your Daily Activity.
Runners live longer, so they say, and a new iPhone app proves it through the theory of special relativity. Just in time for marathon season! As your velocity increases, time as you experience it slows down relative to something moving slower than you. A passenger on a spaceship traveling near the speed of light would appear to have aged less than his friends when he returned to Earth, for instance. Similarly, a fast runner appears to gain time compared to a slow runner.
Einstein's Pedometer brings special relativity to your daily activities, showing how much time you gain by moving. The iPod app, designed by a Japanese developer, uses the iPhone's GPS capabilities and Lorentz transformation equations to calculate this. Einstein's Pedometer is free on the App Store, available for iPod touch, iPhone and iPad devices.
