This mode of like nanoparticles (NPs) of WS2 were discovered some 25 packing explained their large anisotropy with respect to many years ago and are produced now on a commercial scale for physiochemical properties and the facile cleavage along the various applications. This Perspective provides a brief basal (0001) plane. description of recent progress in this scientific discipline. The structure of chloritesnaturally occurring 2D aluminum The conceptual evolution leading to the discovery of these (alumo) and magnesium silicates, which were employed for NTs and NPs is briefly discussed. Subsequently, recent asbestos cementwas studied in 1930 by both Warren and progress in the synthesis of such NPs from a variety of Bragg3 and Pauling4 using XRD. By analyzing the detailed inorganic compounds with layered (2D) structure is packing of these 2D materials, Pauling noticed that some of the described. In particular, we discuss the synthesis
