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 ...

In general, when you measure material properties such as optical permittivity, your measurement doesn’t depend on the direction in which you make it. However, recent research has shown that this is ...

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 ...
