Membrane-based separations are essential for various processes, such as water filtration and oil and gas separation. The use of graphene and other 2D materials in membrane technology has attracted ...

PET membranes with smooth, cylindrical pores are routinely fabricated using a process called track etching ... began to shift when the average separation between tracks approached 20 nanometres.
