"Enhancing Fusion Device Performance with Liquid Lithium Wall Coating"

Originally Published 2 years ago — by Phys.org

Researchers at the Princeton Plasma Physics Laboratory (PPPL) have found that applying a coating of liquid lithium to the internal walls of fusion plasma containment devices, such as tokamaks, helps maintain a hot edge of the plasma. This approach, demonstrated in the Lithium Tokamak Experiment-Beta (LTX-β), could make fusion energy more practical and cost-effective by improving energy confinement and reducing the need for repairs. The liquid lithium absorbs hydrogen ions escaping from the plasma, creating a low-recycling environment that allows for better heat confinement and temperature uniformity within the plasma.

"The Science Behind the Dark and Rough Surface of Black Silicon in Solar Cells"

Originally Published 2 years ago — by Phys.org

Researchers at the U.S. Department of Energy's Princeton Plasma Physics Laboratory (PPPL) have developed a new theoretical model explaining how black silicon, a crucial material used in solar cells and other applications, is created by etching the surface of regular silicon with fluorine gas to produce tiny nanoscale pits that trap more light. The new model reveals how fluorine gas breaks certain bonds in the silicon based on their orientation, creating a rough surface ideal for light absorption. This research represents an early success in PPPL's foray into quantum chemistry and fills a gap in publicly available research on the production of black silicon.
