(Phys.org)—It was another good week for physics as a team of researchers found some ways to increase antihydrogen production—having more of the stuff could lead to better experiments to learn more about antimatter in ...
(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 ...
Vast amounts of excess heat are generated by industrial processes and by electric power plants; researchers around the world have spent decades seeking ways to harness some of this wasted energy. Most such efforts have focused ...
