An operable platform towards functionalization of chemically inert boron nitride nanosheets for flame retardancy and toxic gas suppression of thermoplastic polyurethane

, 2019
The inherent chemical inertness presents a huge challenge for the functionalization of hexagonal boron nitride (h-BN), thus limiting its potential in flame retardant and toxic gas suppression of thermoplasticity polyurethane (TPU).

Organic Surfactant Assisted Polypyrrole Materials as Effective Chemiresistive Gas Sensors for VOCs and Toxic Gas Detection

IEEE Sensors Journal, 2020
Surfactant assisted PPy materials are explored as efficient gas sensors for VOCs and toxic gases in the present work. Polypyrrole nanostructures were prepared by chemical oxidative polymerization using various sulfonic acids as surfactants between 0–5 °C.

The influence of S vacancy on the adsorption of toxic gas molecules on SnS monolayer: A DFT study

, 2020
In the present study, we select the toxic gases such as NO2, NO, SO2, NH3, CO and CO2 to examine the sensing capacity of S-vacancy SnS monolayer as a gas sensor.

A first-principles insight into Pd-doped MoSe2 monolayer: A toxic gas scavenger

Physics Letters, 2019
Using first-principles theory, we investigate the Pd-doping effect on the geometric and electronic behaviors of MoSe2 monolayer, and the adsorption behavior of Pd-MoSe2 monolayer upon four toxic gases, namely NO, NO2 SO2 and H2S.

Terahertz detection of toxic gas using a photonic crystal fiber

Optical fiber technology (Print), 2019
The photon energies of molecules falling rightly into the terahertz region offers a high potential for gas detection. However, detecting gas at low concentration is difficult because of the weak dipole moments of gas in the terahertz region.

Toxic gas dispersion prediction for point source emission using deep learning method

Human and Ecological Risk Assessment, 2019
Accurate and rapid toxic gas concentration prediction model plays an important role in emergency aid of sudden gas leak. However, it is difficult for existing dispersion model to achieve accuracy and efficiency requirements at the same time.

Mechanism of Toxicity of Injected CS Gas

Nature, 1970
IN 1928 Corson and Stoughton1 prepared a number of benzylidene malononitriles, including 2-chlorobenzylidene malononitrile (CS). Although these authors were primarily concerned with the isolation and chemistry of the condensation products of malononitrile and various aldehydes, sternutatory and irritant properties on the part of some of the compounds ...
