CHEMICAL WARFARE HAS EXisted for millennia. As far back as 1000 BC, the Chinese used arsenical smoke as a weapon. In the last century, chemical agents have been used in warfare on numerous occasions, from World War I to the Iran-Iraq conflict. The world remains vulnerable to the deliberate use of chemical agents as weapons of mass destruction. Chemical attacks can be delivered with almost any t...

In present study spray pyrolysis technique was employed to prepare pure and doped CdSnO3 thin films. The spray pyrolyzed thin films were observed to be nanostructured in nature with particle size less than 10 nm and characterized to investigate its structural, microstructural and chemical properties by means of XRD, SEM/EDS, TEM and surface profilometry. Pure and Zn doped CdSnO3 nanostructured ...

purpose : to review ocular surface abnormalities caused by exposure to mustard gas and current approaches to manage its delayed-onset complications methods : a total of 198 medical articles related to mustard gas were reviewed using known international medical databases, 114 articles were more relevant to the main aim were selected. results : mustard gas-related ocular injuries can be divided i...

This paper introduces a new reagent N-phenylbenzylamine for determination of nitrite in water and aqueous solutions. The reagent in the acidic medium coupled with diazotized dapsone to form the azo dye. The reaction provides a sensitive and reproducible determination of nitrite without special modifications of reaction conditions. The detection limit is 0.07 μg.ml, and linear range 0.1-2.0 μg.m...
