Photosynthesis requires a mechanism to produce large amounts of chemical energy without losing the oxidative power needed to break down water. A research team has clarified part of this mechanism, marking another step towards the potential development of artificial photosynthesis.
Humans have appreciated silver's antimicrobial activity for millennia. But it takes 21st-century technology to push the amount of silver needed to combat disease-causing microbes into the nanoscale realm.
Physicists achieved a robust and reliable magnetization switching process by domain wall displacement without any applied fields. The effect is observed in tiny asymmetric permalloy rings and may pave the way to extremely efficient new memory devices.
Researchers have developed a novel technology of embedding highly conductive nanostructure into semi-conductor nanofiber. The novel composite so produced has superb charge conductivity, and can therefore be widely applied, especially in environmental arena.
