Front Cover: MXene based nanocomposite films (EXP2 4/2022)

Henan University was established as “the Preparatory School for Further Study in Europe and America” in 1912. Almost 100 years later, a new two-dimensional (2D) material, MXene, was first reported in 2011. The cover represents the promising and quickly development of new 2D MXene material for applications in electromagnetic interference shielding, thermal conductivity, supercapacitors, etc.
