Single atom modified two-dimensional bismuthenes for toxic gas detection.
Physical Chemistry, Chemical Physics - PCCP, 2023Accurate detection of toxic gases at low concentrations is often difficult because they are colorless, odorless, flammable and denser than air. Therefore, it is urgent to develop highly stable and sensitive toxic gas detectors.

Selective and sensitive toxic gas-sensing mechanism in a 2D Janus MoSSe monolayer.
Physical Chemistry, Chemical Physics - PCCP, 2022With an inspiration of sensing toxic gases, this study is aimed at exploring the potential of a Janus MoSSe monolayer as a gas sensor. Here, we focused on the adsorption mechanism after the exposure to NH3, NO2, NO, HCN, CO2, CO, H2, H2S and SO2 on both ...

Reevaluating tear gas toxicity and safety
Inhalation Toxicology, 2021Tear gases, or chemical demonstration control agents (DCA), were originally created as weapons that could severely disable or kill enemy troops. Though banned in war, these chemicals are still used in domestic policing. Here we review the available scientific literature on tear gas, summarizing findings from animal and environmental studies as well ...
