Researchers realize hydrogen formation by contact electrification of water microdroplets and its regulation
Direct utilization of water as a source of hydrogen atoms and molecules is fundamental to the evolution of the ecosystem and industry. However, liquid water is an unfavorable electron donor for forming these hydrogen species due to its redox inertnes.....»»
Thermal properties of new 2D materials for microchips can now be measured well
Making ever smaller and more powerful chips requires new ultrathin materials: 2D materials that are only 1 atom thick, or even just a couple of atoms. Think about graphene or ultra-thin silicon membrane for instance......»»
Cold Coulomb crystals, cosmic clues: Unraveling the mysteries of space chemistry
