New Type Of Solar Harvesting Could Run 24 Hrs Sets Record
November 16, 2022 | Leave a Comment
A University of Houston professor is reporting on a new type of solar energy harvesting system called thermophotovoltaics (STPV) that breaks the efficiency record of all existing technologies. And no less important, it clears the way to use solar power 24/7. Photovoltaic cells which convert sunlight directly into energy have made much progress. Yet with […]

Fire Stopper Proposed For Lithium Ion Batteries
November 15, 2022 | Leave a Comment
When overheated Lithium-ion (Li-ion) batteries are prone to catching fire or even exploding. Yet they are used to power everything from smart watches to electric vehicles, thanks to the large amounts of energy they can store in small spaces. A recent research paper published in American Chemical Society’ Nano Letters offers a possible solution with […]

Catalyst Cuts The Energy Needed to Make Ammonia Fertilizer
November 10, 2022 | Leave a Comment
Open Image…Save ImageOpen Image (using #TmpD/ia)… Tokyo Institute of Technology researchers have developed a metal nitride catalyst containing an active metal (Ni) on a lanthanum nitride support that is stable in presence of moisture. The goal is to cut the energy requirements of the Haber-Bosch process, which converts nitrogen and hydrogen to ammonia. Plus, since the catalyst doesn’t contain ruthenium, […]
