Molten fluoride salt-assisted synthesis of mxenes as potential material for nonlinear photonic devices and applications / Aizuddin Ahmad Kamely

Group 4–6 transition metal carbides and nitrides were explored in the twentieth century as promising materials. Their catalytic behavior were founded in the 1970s that led to the exploration towards energy storage applications. Henceforth, a number of nanostructure designs have been introduced, taki...
