Cobalt Atoms on Graphene Catalyze Hydrogen Production
October 27, 2015 | Leave a Comment
Rice University researchers report cobalt atoms on nitrogen-doped graphene are a robust solid-state catalyst for hydrogen production. The discovery may be an effective replacement for more expensive platinum-activated catalysts in fuel cells and other energy applications. The Rice lab of chemist James Tour and colleagues at the Chinese Academy of Sciences, the University of Texas […]

Perovskite Solar Cells Get Bigger
October 22, 2015 | 1 Comment
Brown University researchers report a method for making perovskite cells larger while maintaining efficiency. Perovskite solar cells are cheaper to make than traditional silicon cells and their electricity conversion efficiency is improving rapidly. To be commercially viable, perovskite cells need to scale up from lab size. Researchers have reported efficiency in perovskite cells of higher […]

Metamaterial Saves the Lost Heat of Thermal Energy
October 21, 2015 | Leave a Comment
The U.S. is estimated to lose more than half of the energy it generates – mostly because it escapes as waste heat. Scientists are now developing a new type of system to efficiently capture some of that lost heat. They have designed a surface that enhances low frequency thermal radiation, which is easier than higher […]
