Hydrogen, as a scientific topic, encompasses the study of the lightest chemical element (atomic number 1) across its atomic, molecular, ionic, and condensed phases, as well as its roles in physical chemistry, materials science, and energy research. It includes investigation of quantum properties of the hydrogen atom, isotopes (protium, deuterium, tritium), hydrogen bonding, and behavior under extreme conditions leading to phenomena such as metallic hydrogen. The topic also covers hydrogen’s function in acid–base chemistry, redox processes, plasma physics, astrochemistry, and its use as an energy carrier in technologies like fuel cells and hydrogen storage materials.
Neutron scattering techniques were used as part of a study of a novel "nanoreactor" material that grows crystalline hydrogen clathrates, or HCs, capable of storing hydrogen. The researchers, from ORNL and the University of ...
