Graphene is the most broadly discussed and studied two‐dimensional material because of
its preeminent physical, mechanical, optical, and thermal properties. Until now, metal …

The wettability of graphene is both fundamental and crucial for interfacing in most
applications, but a detailed understanding of its time evolution remains elusive. Here we …

Atmospheric pressure X-ray photoelectron spectroscopy (XPS) is demonstrated using single-
layer graphene membranes as photoelectron-transparent barriers that sustain pressure …

Chemical vapour deposition (CVD) is an effective and simple method for production of large
