(Phys.org)—A team of researchers working at Germany's University of Würzburg has shown that a theory developed to describe a way to convert waste heat in microelectronics to electricity can work in the real world. In their ...
Berkeley Lab researchers have developed a nano-sized optical antenna that can greatly enhance the spontaneous emission of light from atoms, molecules and semiconductor quantum dots. This advance opens the door to light-emitting ...

(Phys.org)—To understand cell function, we need to be able to study them in their native environment, in vivo. While there are many techniques for studying cells in vitro, or in the laboratory setting, in vivo studies are ...
Princeton University researchers have built a rice grain-sized laser powered by single electrons tunneling through artificial atoms known as quantum dots. The tiny microwave laser, or "maser," is a demonstration of the fundamental ...
