Physical Study by Surface Characterizations of Sarin Sensor on the Basis of Chemically Functionalized Silicon Nanoribbon Field Effect Transistor [PDF]

J. Phys. Chem. C 120, 11180-11191 (2016), 2016
Surface characterizations of an organophosphorus (OP) gas detector based on chemically functionalized silicon nanoribbon field-effect transistor (SiNR-FET) were performed by Kelvin Probe Force Microscopy (KPFM) and ToF-SIMS, and correlated with changes in the current-voltage characteristics of the devices.

Chemical Weapons: History of the Study of Organophosphorus Toxic Agents Abroad

Вестник войск РХБ защиты, 2023
Organophosphorus compounds occupy a unique positon among all chemical warfare agents (CWA's). Since the 1930-s their high toxicity, wide range of physical-chemical properties and complex action attracted close attention of foreign military experts.

Antioxidants in Organophosphorus Compounds Poisoning [PDF]

Archives of Industrial Hygiene and Toxicology, 2013
Oxidative stress has recently been implicated as a factor in the mortality and morbidity induced by organophosphorus (OP) compound poisoning. An overwhelming number of research papers are based on studying at the cellular and organ level. Such studies have concluded that antioxidants can be used as an adjunct compound in the treatment of both chronic ...

Chemistry, Metabolism and Neurotoxicity of Organophosphorus Insecticides: A Review [PDF]

Nature Environment and Pollution Technology, 2023
Organophosphorus compounds (OPs) are phosphoric acid derivatives represented by the formula (R2XP=O/S), R as organic groups; however, they need not contain a direct carbon-phosphorus bond.

Organocatalytic asymmetric synthesis of P-stereogenic molecules

Frontiers in Chemistry, 2023
P-chirality broadly appears in natural and synthetic functional molecules. The catalytic synthesis of organophosphorus compounds bearing P-stereogenic centers is still challenging, due to the lack of efficient catalytic systems.
