Recent advances in the development of nanoporous graphene (NPG) hold promise for the future of water supply by reverse osmosis (RO) desalination. But while previous studies have highlighted the potential of NPG as an RO membrane, there is less understanding as to whether NPG is strong enough to maintain its mechanical integrity under the high hydraulic pressures inherent to the RO desalination ...

This work is part of a systematic study on the energy barriers for permeation several molecules, like He, H2, CO, CO2, H2O, NH3, CH4 etc, through nanoporous single layer graphene, having pores with different shape, size, and type. In present work, we focus CO2 graphene which are constructed when neighboring carbon atoms removed from structure, nitrogen have replaced in boundary pore. The each p...

Spintronics, which manipulate spins but not electron charge, are highly valued as energy and thermal dissipationless systems. A variety of materials are challenging the realization of spintronic devices. Among those, graphene, a carbon mono-atomic layer, is very promising for efficient spin manipulation and the creation of a full spectrum of beyond-CMOS spin-based nano-devices. In the present a...

The behaviour of a p-xylene-based lyophobic nanoporous carbon system under high hydrostatic pressures is investigated. As the pressure is increased to a critical value, the nanopore surfaces between graphene layers are exposed to the liquid phase, leading to a considerable increase in solid–liquid interfacial energy. During unloading, defiltration does not occur until the pressure is much lower...

Nanoporous carbon (NPC) exhibits unexplained chemical properties, making it distinct from other graphenelike materials, such as graphite, fullerenes, or nanotubes. In this Letter, we analyze the properties of NPC in terms of its structural motifs, which are derived from defects in distorted graphene sheets. Our density-functional theory calculations show that these motifs can be present in high...
