Solid-State Electrochemical Thermal Transistor Without Using Liquid


A new technical paper titled "Solid-State Electrochemical Thermal Transistors" was published by researchers at Hokkaido University, Pusan National University, and the University of Tokyo. Abstract "Thermal transistors that electrically control heat flow have attracted growing attention as thermal management devices and phonon logic circuits. Although several thermal transistors are demons... » read more

Tiny diamond radio Researchers at Harvard built the world's smallest radio receiver, built out of an assembly of atomic-scale defects in pink diamonds. The radio uses tiny imperfections in diamonds called nitrogen-vacancy (NV) centers. To make NV centers, researchers replace one carbon atom in a diamond crystal with a nitrogen atom and remove a neighboring atom -- creating a system that i... » read more
