(Phys.org) —For the past year, researchers at Tsinghua University in Beijing have been listening to music on a laptop through a pair of unusual earphones. Although the earphones look ordinary, they do not contain the typical ...
(PhysOrg.com) -- For years, scientists and researchers have been looking into the properties of carbon nanotubes and graphene for use in nanoelectronics. "There is no real mass application of devices based on graphene and ...
(PhysOrg.com) -- Due to the increasing demand for renewable energy sources, photovoltaic solar cells have advanced significantly over the past decade. Since 2002, photovoltaic production worldwide has been doubling every ...
True to Moore's Law, the number of transistors on a microchip has doubled every year since the 1960s. But this trajectory is predicted to soon plateau because silicon—the backbone of modern transistors—loses its electrical ...
