(Phys.org) —A research team at the University of Southampton in England has built a fiber cable that is capable of carrying data at 99.7 percent of the vacuum-speed of light. They have done so, they report in their paper ...
(Phys.org)—Scientists have designed a new multijunction solar cell that, in simulations, can achieve an efficiency of 51.8%. This high performance exceeds the current goal of 50% efficiency in multijunction solar cell research ...
By fabricating graphene structures atop nanometer-scale "steps" etched into silicon carbide, researchers have for the first time created a substantial electronic bandgap in the material suitable for room-temperature electronics. ...
