Engineers work on new material for computer chips

The amount of energy used for computing is climbing at an exponential rate. Business intelligence and consulting firm Enerdata reports that information, communication and technology accounts for 5% to 9% of total electricity ...

Switchable material could enable new memory chips

Two MIT researchers have developed a thin-film material whose phase and electrical properties can be switched between metallic and semiconducting simply by applying a small voltage. The material then stays in its new configuration ...

Penn team studies nanocrystals by passing them through tiny pores

An interdisciplinary team of University of Pennsylvania researchers has now applied a cutting-edge technique for rapid gene sequencing toward measuring other nanoscopic structures. By passing nanoscale spheres and rods through ...

A Straightforward Solution for Increasing Solar Cell Performance

(PhysOrg.com) -- Brookhaven National Laboratory researchers recently demonstrated improved stability and efficiency of a certain type of solar cell by incorporating a commercially available additive into the fabrication process.

Rare earth metals: Another challenge for the green economy?

If you follow the clean energy dialogue, then you may have encountered discussions about the role of rare earth metals at some point in the last year or two. If not, read on, because rare earths should not be a rare topic ...

Engineers create structures tougher than bulletproof vests

Researchers at UT Dallas have created new structures that exploit the electromechanical properties of specific nanofibers to stretch to up to seven times their length, while remaining tougher than Kevlar.
