主权项

1. A composition comprising at least one layer having first and second surfaces, each layer comprising:
a substantially two-dimensional array of crystal cells, each crystal cell having an empirical formula of Mn+1Xn, such that each X is positioned within an octahedral array of M, wherein M is at least one Group IIIB, IVB, VB, or VIB metal, wherein each X is C, N, or a combination thereof and n=1, 2, or 3.
