“…Thus, even He (as the smallest monoatomic molecule with a molecular radius of 1.3 Å) cannot pass through it. 26,27 However, according to simulations, by the inclusion of pores of controlled size, density and functionality, graphene membranes can surpass current desalination membranes, showing orders of magnitude higher permeability and selectivity ( Figure 4). 28 Molecular dynamics simulations have predicted that nanoporous graphene, due to its extraordinary water flow rate (up to 66 l.cm − 2 .day −1 .MPa −1 ) and high (499%) salt rejection (depending on the pore size and chemistry), may be one of the most desirable materials for water desalination.…”

“…37 On the other hand, nanoparticles inside an organism may affect physiological systems and the metabolic process. For example, because of the high electron density on the surface, 45 graphene oxide nanoparticles act as electron transfer mediators and catalyze H 2 O 2 decomposition to OH in Caenorhabditis elegans (C. elegans). 46 Involvement in physiological redox reactions has emerged as an important mechanism accounting for the toxicity of nanoparticles.…”

“…Graphene nanoplatelets are impermeable to gases such as helium if the platelets contain no defects [31][32][33] and is already being applied in coatings as barriers against the release of toxic substances [31,34]. If this is the case, then graphene nanopolymer composite coatings might be useful in limiting the release of radioactive gases like tritium ( 3 H) from irradiated graphite waste.…”
