Scientists in Japan have developed a new organic device that can harvest energy from heat. Unlike other thermoelectric generators, this one works at room temperature without a heat gradient.Continue ReadingCategory: Energy, TechnologyTags: Energy, Ther… Continue reading Thermoelectric generator pulls energy from room temperature heat
Researchers have converted brain immune cells into neurons, replacing damaged ones and restoring function in stroke-affected mice. The next step is to see if the same results can be achieved using human brain cells, opening the door to a potential trea… Continue reading Converting brain immune cells into neurons aids post-stroke recovery
While the data on most memory devices can be read using electric signals, an emerging technology encodes data in light, so a system can read it back just by checking if an LED is on or off. Now, researchers have developed a new device based entirely on… Continue reading Perovskite memory device transmits data in both light and electricity
Engineers have found a way to make liquid metals switch between reflective surfaces or those that scatter light. The transition only requires a small zap of electricity and could be used to make mirrors that can be switched on or off.Continue ReadingCa… Continue reading Liquid metal mirrors switch reflectivity on and off with a zap
