| Heat-conducting plastic: 10 times better than conventional counterparts Posted: 26 Nov 2014 02:16 PM PST The spaghetti-like internal structure of most plastics makes it hard for them to cast away heat, but a research team has made a plastic blend that does so 10 times better than its conventional counterparts.  |
| High-tech mirror beams heat away from buildings into space Posted: 26 Nov 2014 10:38 AM PST Engineers have invented a material designed to help cool buildings. The material reflects incoming sunlight, and it sends heat from inside the structure directly into space as infrared radiation.  |
| Shaping the future of energy storage with conductive clay Posted: 26 Nov 2014 10:26 AM PST Materials scientists have invented clay, which is both highly conductive and can easily be molded into a variety of shapes and sizes. It represents a turn away from the rather complicated and costly processing -- currently used to make materials for lithium-ion batteries and supercapacitors -- and toward one that looks a bit like rolling out cookie dough with results that are even sweeter from an energy storage standpoint.  |
| Posted: 26 Nov 2014 09:44 AM PST Engineering researchers have developed a chip on which both sound wave and light wave are generated and confined together so that the sound can very efficiently control the light.  |
| Van der Waals force re-measured: Physicists verified nonlinear increase with growing molecular size Posted: 26 Nov 2014 04:51 AM PST Van der Waals forces act like a sort of quantum glue on all types of matter. Using a new measuring technique, scientists experimentally determined for the first time all of the key details of how strongly the single molecules bind to a surface. With an atomic force microscope, they demonstrated that the forces do not just increase with molecular size, but that they even grow disproportionately fast.  |
