In recent years, graphene has been perhaps the most studied material around the globe. It has served as a classic example of 2D materials, not just because of historical reasons, but importantly, due to its distinctly observable dimensional crossover ability – from 2D to 3D – via Bernal-stacked (AB) bilayer to multilayer, finally culminating in graphite. Applications, such as conducting inks and catalysts borne out of graphene, are already in widespread use. Recently, there has been an emergence of a range of new 2D materials: some elemental (borophene, phosphorene, antimonene, silicene, etc.) and many based on layered compounds such as BN, MoS2 in addition to MXenes. Mixed systems, such as BCNs, mixed chalcogenides, etc., are yet another class of new 2D materials. Currently, graphene and many 2D systems are being revisited in their twisted varieties because of the amazing properties they exhibit, for instance, superconductivity.
In this issue, we invite contributions on tailor-made new 2D materials, small and large area applications of 2D materials in electronics, purifiers and catalysis, as well as theoretical studies on structure and properties of such materials and phenomena.
