(Phys.org)—In 2011, the research group of Roland Wiesendanger, Physics Professor at the University of Hamburg in Germany, fabricated a spin-based logic device using the spins of single atoms, a feat that represents the ultimate ...
(Phys.org)—Researchers have designed a new type of microgear that spins when micromotors become lodged into the corners of the gear's teeth. The micromotors use the surrounding hydrogen peroxide solution as fuel to propel ...
(Phys.org)—Researchers have fabricated a stretchable and transparent electrode that can be used for applications such as heating parts of the body and defrosting the side view mirrors on cars. It is the first stretchable ...
(Phys.org)—Researchers have demonstrated that coating a cobalt film in graphene doubles the film's perpendicular magnetic anisotropy (PMA), so that it reaches a value 20 times higher than that of traditional metallic cobalt/platinum ...
(Phys.org)—Physicists have built a nanowire cage that blocks one or more wavelengths of light from either entering or escaping, yet allows liquids and gases to pass through the small gaps between the nanowires. The "optical ...
(Phys.org)—Researchers have created a self-powered electronic watch that harvests energy from the wearer's wrist movements for continuous operation. By combining two different energy conversion mechanisms (electromagnetic ...
(Phys.org)—Dissipation and decoherence are typically considered harmful to solar cell efficiency, but in a new paper scientists have shown that these effects paradoxically make the exciton lifetime in semiconducting carbon ...
(Phys.org)—Flash memory—the data storage method often used in phones, computers, and other devices—is continually being miniaturized in order to improve device performance. In an attempt to reduce the short-circuiting that ...
(Phys.org)—Scientists have built a battery containing a magnetic fluid that can be moved in any direction by applying a magnetic field. The magnetically controlled battery concept could be especially useful for flow batteries, ...
(Phys.org)—Electrons can move through graphene with almost no resistance, a property that gives graphene great potential for replacing silicon in next-generation, highly efficient electronic devices. But currently it's very ...
