Enhanced Thermal- and Photostability of Trace Pyrazine-Incorporated Hydrogen Boride Nanosheets

Researchers at the School of Materials and Chemical Technology in Tokyo, Japan, have successfully developed a novel hydrogen-rich material with controllable hydrogen-release properties under various stimuli. The scientists, led by Jumpei Takeshita, have created pyrazine-incorporated hydrogen boride (Pyrazine-HB) nanosheets through a simple solution-mixing and drying process. These nanosheets exhibit significantly
