Now, acoustic tweezers to position tiny objectsAugust 29th, 2009 WASHINGTON - While it gets quite difficult to manipulate tiny objects like single cells or nanosized beads via relatively large, unwieldy equipment, Penn State engineers have now designed a new system that uses sound as a pair of tiny tweezers that are small enough to place infinitesimal objects on a chip. While optical tweezers are large and expensive, acoustic tweezers are smaller than a dime, small enough to fabricate on a chip using standard chip manufacturing techniques.
Computer game aims to solve world's energy problemsAugust 18th, 2009 WASHINGTON - In a rare "thought experiment," scientists will try to find a solution to the world's energy problems with the help of a computer game. The "thought experiment" will be held at the American Chemical Society's (ACS) 238th National Meeting, which is intended to focus the creative genius of hundreds of scientists on solutions to one of the 21st Century's most daunting problems: Finding sustainable new sources of energy.
Micro robo flies can save up to 50 percent energy if they fly like helicoptersAugust 8th, 2009 WASHINGTON - A new study has shown that micro flying robots that hover like flies can save up to 50 percent energy if they swing an insect wing around like a helicopter blade. Previously, engineers have long been stymied in their attempts to fabricate micro aerial robots that can match the amazing flight capabilities of nature's most advanced flying insects - flies.
New lab-on-a-chip device which runs on musicJuly 23rd, 2009 WASHINGTON - Its music, not electromechanical valves, that controls a novel lab-on-a-chip device designed at the University of Michigan (UM). The new system could significantly simplify the process of conducting experiments in microfluidic devices.
Energy Department to loan money to Ford Motor Co. to develop fuel-efficient vehiclesJune 22nd, 2009 Ford to get loan to develop fuel-efficient autosWASHINGTON — The Energy Department is expected to announce that Ford Motor Co. will receive funds from a $25 billion federal loan program to develop fuel-efficient vehicles.
New exotic material brings highly efficient computer chips closer to realityJune 16th, 2009 WASHINGTON - U.S. scientists have confirmed that there exists a type of material that could one day provide dramatically faster, more efficient computer chips.
Indian-Americans engineer radio chip that mimics human earJune 4th, 2009 WASHINGTON - Indian Americans have engineered a fast, ultra-broadband, low-power radio chip mimicking the inner ear, or cochlea, one that could enable wireless devices to receive cell phone, Internet, radio and TV signals. Rahul Sarpeshkar, MIT associate professor of electrical engineering and his graduate student, Soumyajit Mandal, designed the chip.
Indian-origin researchers' human ear-mimicking chip may provide a better radioJune 4th, 2009 WASHINGTON - A team of Indian-origin researchers at the Massachusetts Institute of Technology (MIT) have modelled a fast, ultra-broadband, low-power radio chip on the human inner ear. Rahul Sarpeshkar, associate professor of electrical engineering and computer science, and his graduate student Soumyajit Mandal say that their device may enable wireless devices capable of receiving cell phone, Internet, radio and television signals.
Laser doubles brightness of bulb filamentsMay 30th, 2009 WASHINGTON - An ultra-powerful laser not only doubles the brightness of light bulbs filaments but also slashes their power consumption, according to a new study. "We've been experimenting with the way ultra-fast lasers change metals, and we wondered what would happen if we trained the laser on a filament," said Chunlei Guo, associate professor of optics at the University of Rochester, who led the research.
Rain puts damper on coming-out party to preview new White House fleet of energy-efficient carsApril 22nd, 2009 White House cars fuel-efficient but not waterproofWASHINGTON — Quickie quiz? What do the Obama White House and the Washington Nationals baseball team have in common? They're both snakebitten by rain delays. The Nationals suffered rain delays on both Monday and Tuesday nights, and the White House unwittingly shared in the pain of rain Wednesday morning.
Smart card material to help computers switch on instantlyApril 18th, 2009 WASHINGTON - Ultra-thin ferro-electric materials used in smart cards will soon make computers more efficient by enabling them to switch on instantly. Smart cards rely on ferro-electric materials to instantly reveal and update stored information.
Slimmer nanorods may revolutionise 3-D computer chip technologyMarch 19th, 2009 WASHINGTON - Scientists have developed a new technique for growing slimmer copper nanorods, a breakthrough that can pave the way for advanced integrated 3-D chip technology. The researchers have found a new method to grow slimmer copper nanorods, which can be used as a low-temperature bonding agent for holding together the layers of next-generation 3-D integrated computer chips.
Indian-American designs energy efficient super microchipFebruary 9th, 2009 WASHINGTON - A team led by an Indian-American scientist has developed a superfast microchip that is seven times faster, but uses 30 times less energy than the best that technology has to offer today. The technology, dubbed PCMOS (probabilistic complementary metal-oxide semiconductor), was invented by Krishna Palem, professor of Rice University and director, Nanyang Technological University (NTU) Institute for Sustainable Nanoelectronics (ISNE), Singapore.
Robotic hands designed by Indian American move ultra-tiny particlesJanuary 16th, 2009 WASHINGTON - Microscopic, chemically triggered robotic 'hands' developed by biomolecular engineers, led by an Indian American, can move ultra-tiny components. These chemically triggered microscopic devices or 'hands', that manipulate particles smaller than a grain of sand, can be used in lab-on-a-chip applications and micro-manufacturing, the researchers say.
