Cheap, Strong Lithium-Ion Battery Developed
Researchers at USC have developed a new lithium-ion battery design that uses porous silicon nanoparticles in place of the traditional graphite anodes to provide superior performance. The new batteries—which could be used in anything from cell phones to hybrid cars—hold three times as much energy as comparable graphite-based designs and recharge within 10 minutes. The […]
New Material Promises Better Solar Cells
Single atomic layers are combined to create novel materials with completely new properties. Layered oxide heterostructures are a new class of materials, which has attracted a great deal of attention among materials scientists in the last few years. A research team at the Vienna University of Technology, together with colleagues from the USA and Germany, […]
Virtual Vehicle Vibrations
“Sit up straight in your chair!” That command given by countless parents to their children may one day be delivered by vehicle designers to a robot that is actually a computerized model of a long-distance truck driver or other heavy equipment operator, thanks to a University of Iowa research program.

The Internet has changed drastically over the past 10 years, and, much to the chagrin […]
Artificial atoms allow for magnetic resonance on individual cells
Scientists at ICFO develop a technique for MRIs on a molecular scale Researchers from the Institute of Photonic Sciences (ICFO), in collaboration with the CSIC and Macquarie University in Australia, have developed a new technique, similar to the MRI but with a much higher resolution and sensitivity, which has the ability to scan individual cells. […]
