Researchers use fully quantum-mechanical simulations to study proton diffusion in acids, finding that the proton migrates by interconverting hydrogen bonds into strong covalent bonds. Quantum tunneling is not involved, and the defect's delocalization is induced by zero-point motion of excess protons.
Researchers gathered unprecedented data from NASA aircraft in Atlantic hurricanes Bonnie, Danielle, Earl, and Georges, shedding light on complex wind patterns and rainfall enhancement by mountains. The study aims to improve hurricane forecast capabilities, saving lives and reducing evacuation zones.
Researchers from University of California call for changes in management of agricultural and environmental resources to ensure sustainable food production and efficient water resource use. They emphasize the need for increased cooperation, public-private partnerships, and research into water resources management.
