Keywords: Graphene, graphene-based membranes, van der Waals pressure

Van der Waals assembly of two-dimensional crystals continue attract intense interest due to the prospect of designing novel materials with on-demand properties. One of the unique features of this technology is the possibility of trapping molecules between two-dimensional crystals. The trapped molecules are predicted to experience pressures as high as 1 GPa. In my talk, I will discuss the experimental demonstration of the huge van der Waals pressure inside the nano-enclosures made from 2D crystals. Another feature of van der Waals material assembly is the unique possibility of designing two-dimensional channels for molecular transport. Permeation through nanometre-pore materials has been attracting unwavering interest due to fundamental differences in governing mechanisms at macroscopic and molecular scales, the importance of water permeation in living systems, and relevance for filtration and separation techniques. Graphene-based materials can have well-defined nanometer pores and can exhibit low frictional water flow inside them, making their properties of interest for filtration and separation. In my talk, I will discuss our recent results on molecular and ionic permeation properties of various 2D materials based membranes and its prospect for several applications.
