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.
Electrospinning is a technique that produces ultra-fine fibers that are up to 100 times thinner than a human hair. These fibers are collected on glass or on foils in an unstructured, wide mesh net. When conductive materials are spun, flexible conductive transparent electrodes could be produced.
Researchers have solved a problem hindering development of highly sensitive optical devices made of a material called graphene, an advance that could bring applications from imaging and displays to sensors and high-speed communications.
