MXenes: Two-Dimensional Crystals
Babak Anasori, Michael Naguib, Dr. Yury Gogotsi, and Dr. Michel Barsoum.

Description: Two-dimensional Ti₃C₂ layers with surface groups of OH and/or F were formed by immersing Ti₃AlC₂ powder in concentrated hydrofluoric acid which results in selective etching of the Al layers. Since Ti₃AlC₂ is a member of a large family of layered, ternary carbides and nitrides called MAX phases, this discovery opens the door to synthesis of a large number of 2-D solids with different chemistries that can be manipulated to tune properties.
