Porous materials are widely used for gas storage, separation, catalysis, and environmental purification. Their functionality arises from nanoscale pores that allow molecules to be selectively captured ...

Van der Waals heterostructures are artificial materials formed by stacking atomically thin layers of distinct two-dimensional crystals through weak interlayer forces. This modular approach transcends ...

Two-dimensional (2D) materials are crystalline sheets one or a few atoms thick, characterised by strong in-plane covalent bonds and weak out-of-plane van der Waals forces. Beginning with graphene, the ...
