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 […]

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 […]

Researchers led by Shanhui Fan from Stanford University have designed an off-grid, low-cost modular energy source that can efficiently produce power at night. The system uses commercially available technology and could eventually help meet the need for nighttime lighting in urban areas or provide lighting in developing countries. Although solar power brings many benefits, its […]

Researchers reporting in American Chemical Society’s (ACS) Nano Letters have developed a hydrogel that can both cool down electronics, such as cell phone batteries, and convert their waste heat into electricity. Sometimes using electronic devices for too long with too much power can cause them to overheat, which might slow them down, damage their components […]

Osaka University researchers have found that thermoelectric power generators lose a great deal of their possible output power because of thermal and electrical contact resistance. Improving this limitation will help society power interconnected technologies of the future. Interconnected healthcare and many other future applications will require internet connectivity between billions of sensors. The devices that […]
