Two-dimensional (2D) materials, which are only a few atoms thick, are known to exhibit unique electrical, mechanical and optical properties, which differ considerably from the properties of bulk ...

Van der Waals forces, once deemed too weak for structural integrity, have been shown to create stable, highly porous frameworks with exceptional thermal resilience and reversible assembly, paving the ...

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 ...
