Adsorption of toxic gas molecules on the pre-oxidized Cu2Si nanosheet – A DFT study

, 2020
Using first principles calculation, we investigated the adsorption mechanism of small toxic gas molecules (NO, NO2, NH3, CO, CO2, and SO2) by employing van der Waals (vdW) corrections to study the structural, electronic, magnetic and gas sensing ...

Toxicity of mustard gas skin lesions

Microscopy Research and Technique, 1997
Although the exact pathogenesis of mustard gas-induced dermal toxicity remains elusive, morphopathological data gathered in controlled animal and in vitro investigations is providing important clues as to approximate mechanisms. Our laboratory has been studying dermal effects of the chemical warfare agent, sulfur mustard, in a variety of animal models,

A dynamic approach for evaluating the consequences of toxic gas dispersion in the chemical plants using CFD and evacuation modelling

, 2020
Accidental releases of toxic gas in the chemical plants have caused significant harm to the exposed occupants. To evaluate the consequences of these accidents, a dynamic approach considering the gas dispersion and behavior evacuation modelling has been ...

Colonic gas distribution in toxic megacolon

Gastroenterology, 1981
To determine whether dilation of the transverse colon is a specific pathophysiologic feature in toxic megacolon, plain films of the abdomen in different positions were obtained of 6 patients with ulcerative colitis complicated by toxic megacolon.

Accident modeling of toxic gas-containing flammable gas release and explosion on an offshore platform

, 2020
Toxic gas-containing flammable gas leak can lead to poisoning accidents as well as explosion accidents once the ignition source appears. Many attempts have been made to evaluate and mitigate the adverse effects of these accidents.

Adsorption of toxic gas molecules on pristine and transition metal doped hexagonal GaN monolayer: A first-principles study

Vacuum, 2019
Using the first-principles calculations based on density functional theory (DFT-D2 method), we systematically study the structural, energetic, electronic and magnetic properties of toxic gas molecules (H2S, NH3 and SO2) adsorbed on pristine and ...

A novel approach for hazardous area identification of toxic gas leakage accidents on offshore facilities

, 2020
Some attempts have been made to predict the adverse effects of released toxic gas on individuals. However, the classification of the hazardous area considering the dynamic changes and focusing on the whole facility remains a challenging issue. This paper
