In materials science, MXenes (pronounced "max-enes") are a class of two-dimensional inorganic compounds along with MBenes, that consist of atomically thin layers of transition metal carbides, nitrides, or carbonitrides. MXenes accept a variety of hydrophilic terminations. The first MXene was reported in 2011 at Drexel University's College of Engineering, and were named by combining the prefix "MAX" or "MX" (for MAX phases), with "ene" by analogy to graphene.
