MXenes are emerging 2-D materials that are extremingly promising for applications in electronic and energy storage devices (Science 341, 1502, 2013; Nat. Commun. 4, 1716, 2013). However, due to their nanomaterial nature, it has proven impossible to solve their structures by means of traditional x-ray crystallography. Atomic pair distribution function technique (PDF), on the other… Read More PDF unveils the structure of important 2D nanocrystalline MXene materials
