Graphene nanobubbles can act as enclosures for holding small volumes of substances. Here the authors find a correlation between bubble shape and the encapsulated material providing a potential method for determining the graphene bubble content by its

Molecules trapped between the layers of two-dimensional materials are thought to experience high pressure. Here, the authors report measurements of this interfacial pressure by capturing pressure-sensitive molecules and studying their structural chan

Most of the studied two-dimensional (2D) materials have been obtained by exfoliation of van der Waals crystals. Recently, there has been growing interest in fabricating synthetic 2D crystals which have no layered bulk analogues.

Despite many theoretical schemes, the direct experimental observation of supramolecular control over band gap opening in single-walled carbon nanotubes (SWNTs) is still lacking. We report an experimental and theoretical demonstration of a metal-to-se
