The Place of Gas Analysis in Forensic Toxicology

Modeling of magnesium-decorated graphene quantum dot nanostructure for trapping AsH3, PH3and NH3gases

“…[27][28][29] Hence, it is of utmost importance that these gases should be sensed or detected. 30 Numerous efforts have been made through the density functional theory (DFT) method towards the sensing and adsorption of XH 3 (X = As, N, P) gases using a graphene or graphene-like structure. NH 3 , PH 3 , and AsH 3 adsorption and sensing on alkaline earth metal (AEM = Be, Mg, Ca and Sr)-doped graphene was conducted by Singsen et al 31 Their results revealed that the gases were weakly absorbed on intrinsic graphene.…”
