Duke University materials scientists have uncovered an atomic mechanism that makes certain thermoelectric materials such as iron sulfide incredibly efficient near high-temperature phase transitions. The information will help fill critical knowledge gaps in the computational modeling of such materials, potentially allowing researchers to discover new and better options for technologies that rely on transforming heat […]

A joint research team from POSTECH and Korea University has demonstrated a daytime radiative cooling material which exhibits lower temperatures than its surroundings even during the day. Now that autumn is here, there is a large temperature gap between day and night. This is due to the temperature inversion caused by radiative cooling on the […]

Oak Ridge National Laboratory and the University of Tennessee, Knoxville have discovered a way to slow phonons, the waves that transport heat. The discovery could improve novel hot-carrier solar cells, which convert sunlight to electricity more efficiently than conventional solar cells by harnessing photogenerated charge carriers before they lose energy to heat. ORNL’s Michael Manley […]

University of Arkansas physicists have successfully generated an electrical current from the atomic motion of graphene, discovering a new source of clean, limitless power. Paul Thibado, professor of physics and lead researcher in the discovery said, “An energy-harvesting circuit based on graphene could be incorporated into a chip to provide clean, limitless, low-voltage power for […]

Open Image…Save ImageOpen Image (using #TmpD/ia)… Oak Ridge National Laboratory researchers have designed and additively manufactured a first-of-its-kind aluminum device that enhances the capture of carbon dioxide emitted from fossil fuel plants and other industrial processes. Solutions for reducing global emissions of heat-trapping greenhouse gases such as CO2 address the continued use of low-cost, domestic fossil fuel resources while mitigating […]
