nanocrystalline magnesium oxides were prepared by sol–gel method and were characterized by x-ray diffraction, n2-bet, sem and infrared spectroscopy techniques. the results confirmed the formation of nano- mgo materials with crystallite size in range of 5-20 nm and surface areas of 336-556m2/g. the product has been tested as destructive adsorbent for the decontamination of (2-chloroethyl) ethyl ...

In this work, ZnCaO2 (zinc oxide-calcium oxide) nanocomposite were synthesized at different temperatures (500-700°C) by sol-gel method based on polymeric network of polyvinyl alcohol (PVA). The synthesized samples were characterized by SEM/EDAX, FT-IR and XRD techniques. It was found that synthesized nanocomposites have 1.62, 2.05 and 13.91%wt of CaO, respectively. The obtained results show tha...

Inexpensive strategies for efficient decontamination of hazardous chemicals are required. In this study, the effect visible light (λ > 400 nm) on decomposition 2-chloroethyl ethyl sulfide (2-CEES, a sulfur mustard (HD) simulant) Au/TiO2 photocatalyst under anaerobic and aerobic conditions has been investigated in situ by diffuse reflectance infrared Fourier –transformed spectroscopy (DRIFTS)...

The detection and identification of chemical warfare agents is an important analytical goal. Herein, it is demonstrated that 2-chloroethyl ethyl sulfide (half-mustard, CEES) can be successfully analysed using surface-enhanced Raman spectroscopy (SERS). A critical component in this detection system is the fabrication of a robust, yet highly enhancing, sensor surface. Recent advances in substrate...

Sulfur mustard (SM), a chemical warfare agent, is strong alkylating compound that readily reacts with numerous biomolecules. The goal of the present work was to define and validate new biomarkers exposure SM could be easily accessible in urine or plasma. Because investigations using are prohibited by Organization for Prohibition Chemical Weapons, we worked 2-chloroethyl ethyl sulfide (CEES), mo...

We recently showed that acute oxidant-related lung injury (ALI) in rats after application of 2-chloroethyl ethyl sulfide (CEES) is attenuated by the airway instillation of antioxidants. We investigated whether intratracheal administration of antioxidant-containing liposomes immediately after instillation of CEES would attenuate short-term as well as long-term (fibrotic) effects of CEES-induced ...
