Energy-efficient ultrafast microwave crystalline phase evolution for designing highly efficient oxygen evolution catalysts

Engineering the optical properties of nickel sulphide thin films by zinc integration for photovoltaic applications

“…9 The chemical composition of the nickel sulde comprises of many crystalline phases with varied stoichiometry ranging from Ni-sufficient to Ni-rich materials, such as NiS, NiS 2 Ni 3 S 2 , Ni 3 S 4 , Ni 7 S 6 , and Ni 9 S 8 . 10 Due to its highly specialized uses, including solar cells, lithium-ion batteries, photocatalytic H 2 production, and supercapacitors, NiS has seen an increase in interest. 11,12 The hexagonal, P63/ mmc high-temperature phase-NiS and the low-temperature phase-NiS are the two potential phases of NiS (rhombohedral, R3m).…”
