Cool Electronics and Recover the Heat
April 28, 2020 | Leave a Comment
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 […]

Ways to Improve Thermoelectric Performance Explored
April 2, 2020 | Leave a Comment
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 […]

Laser Etch a Perfect Radiant Energy Absorber
March 12, 2020 | Leave a Comment
University of Rochester researchers have demonstrated how laser etching of metallic surfaces creates the ”perfect solar energy absorber”. This not only enhances energy absorption from sunlight, but also reduces heat dissipation at other wavelengths. The researchers also demonstrated solar energy harnessing with a thermal electric generator. The University of Rochester research lab that recently used […]
