New Finding May Explain Heat Loss in Fusion Reactors

Researchers at MIT’s Plasma Science and Fusion Center, working with the University of California - San Diego, General Atomics, and the Princeton Plasma Physics Laboratory, say that they have found the key to the mismatch between theory and experimental results – the interactions between turbulence at the tiniest scale, that of electrons, and turbulence at a scale 60 times larger, that of ions.

UCR Researchers Discover New Method to Dissipate Heat in Electronic Devices

For the first time, an international team of scientists led by a researcher at the University of California, Riverside has modified the energy spectrum of acoustic phonons— elemental excitations, also referred to as quasi-particles, that spread heat through crystalline materials like a wave—by confining them to nanometer-scale semiconductor structures.

Atomic Imperfections

Using cutting-edge first-principles calculations, researchers at the UC Santa Barbara have demonstrated the mechanism by which transition metal impurities — iron in particular — can act as nonradiative recombination centers in nitride semiconductors.
