(Phys.org)—Although quantum theory can explain three of the four forces in nature, scientists currently rely on general relativity to explain the fourth force, gravity. However, no one is quite sure of how gravity works ...
(Phys.org)—It may sound counterintuitive that replacing one of the most photosensitive solar cell materials with a material with less desirable photosensitive properties can improve the solar cell's efficiency, but that's ...
(Phys.org) -- Researchers at the Center for Nanophysics and Advanced Materials of the University of Maryland have developed a new type of hot electron bolometer a sensitive detector of infrared light, that can be used in ...
