Toughened Silicon Sponges May Make Tenacious Batteries
July 16, 2012 Researchers have found a way to make multiple high-performance anodes from a single silicon wafer. The process uses simple silicon to replace graphite as an element in rechargeable lithium-ion ... > full story -
Human Eye Inspires Clog-Free Ink Jet Printer
July 16, 2012 Clogged printer nozzles waste time and money while reducing print quality. Engineers recently invented a clog-preventing nozzle cover by mimicking the human ... > full story -
Carbon-Based Transistors Ramp Up Speed and Memory for Mobile Devices
July 16, 2012 By using carbon molecules called C60 to build a sophisticated new memory transistor, scientists have found a way to increase both speed and memory on mobile devices -- and the solution is ready to be ... > full story -
To Extinguish a Hot Flame, Scientists Studied Cold Plasma
July 12, 2012 DARPA theorized that by using physics techniques rather than combustion chemistry, it might be possible to manipulate and extinguish flames. To achieve this, new research was required to understand ... > full story -
Highly Conductive and Elastic Conductors Created Using Silver Nanowires
July 12, 2012 Researchers have developed highly conductive and elastic conductors made from silver nanoscale wires. These elastic conductors could be used to develop stretchable electronic devices. Stretchable ... > full story -
Platinum Is Wrong Stuff for Fuel Cells Because It Wastes Energy, Expert Says
July 12, 2012 Fuel cells are inefficient because the catalyst most commonly used to convert chemical energy to electricity is made of the wrong material, a researcher argues. During the oxygen reduction reaction, ... > full story -
Keeping Electric Vehicle Batteries Cool
July 12, 2012 Heat can damage the batteries of electric vehicles – even just driving fast on the freeway in summer temperatures can overheat the battery. An innovative new coolant conducts heat away from the ... > full story -
One Step Closer to New Kind of Thermoelectric 'Heat Engine'
July 11, 2012 Researchers who are studying a new magnetic effect that converts heat to electricity have discovered how to amplify it a thousand times over -- a first step in making the technology more ... > full story -
No Reliable Evidence on Effectiveness of Electric Fans in Heatwaves
July 11, 2012 A fan might help to increase heat loss if the temperature is below 35°C and the fan is not directly aimed at the person, but, when temperatures are above 35 °C, the fan might actually ... > full story -
Making 'Renewable' Viable: New Technology for Grid-Level Electrical Energy Storage Developed
July 11, 2012 Researchers have developed a new method for quickly and efficiently storing and discharging large amounts of energy. Their "electrochemical flow capacitor," which is fully scalable, could be the key ... > full story
