Nickel, as a scientific topic, encompasses the study of this transition metal’s physicochemical properties, coordination chemistry, and roles in catalysis and materials science. Research addresses its electronic structure (3d⁸4s²), multiple oxidation states (commonly 0, +2, +3), and strong ligand-field interactions that govern reactivity in organometallic and bioinorganic complexes. Nickel is central in heterogeneous catalysis (e.g., hydrogenation, reforming), electrode materials, and corrosion-resistant alloys, where microstructure, phase behavior, and surface chemistry determine performance. Topics also include nickel’s role in metalloenzymes, its toxicology and environmental cycling, and its behavior in advanced functional materials such as superalloys, batteries, and magnetic or catalytic nanostructures.
Researchers have discovered that atoms can be mixed, separated, and recombined within the same experiment, providing a pathway to a record-breaking catalyst for green hydrogen production. In their study, the team created ...
