| Why some liquids are 'fragile' and others are 'strong' Posted: 27 Aug 2014 01:34 PM PDT Only recently has it become possible to accurately 'see' the structure of a liquid. Using X-rays and a high-tech apparatus that holds liquids without a container, a physicist has compared the behavior of glass-forming liquids as they approach the glass transition. The results are the strongest demonstration yet that bulk properties like viscosity are linked to microscopic ones like structure. |
| Novel 'butterfly' molecule could build new sensors, photoenergy conversion devices Posted: 27 Aug 2014 01:33 PM PDT Exciting new work has led to a novel molecular system that can take your temperature, emit white light, and convert photon energy directly to mechanical motions. And, the molecule looks like a butterfly. |
| Materials Other Than Silicon for Next Generation Electronic Devices Posted: 27 Aug 2014 09:25 AM PDT Silicon has been the most successful material of the 20th century, with major global industries and even a valley named after it. But silicon may be running out of steam for high performance/low power electronics. As silicon strains against the physical limits of performance, could a material like InGaAs provide enough of an improvement over silicon that it would be worth the expense in new equipment lines and training to make the switch worthwhile? |
