Surface-enhanced Raman scattering (SERS) is a powerful spectroscopic technique for selective detection and quantification of molecules at extremely low concentrations. However, practical SERS applications gaseous chemicals with small cross section still in its early stages. We herein report plasmonic-sorbent thin-film platform integrated internal standard outstanding sensing capabilities chemic...

2-Chloroethyl ethyl sulfide (CEES) is used as a simulant for mustard (HD) in a study to develop secondary ion mass spectrometry (SIMS) for rapid, semi-quantitative detection of mustard on soil. Using SIMS with single-stage mass spectrometry, a signature for CEES can be unequivocally observed only at the highest concentrations (0.1 monolayer and above). Selectivity and sensitivity C2H5SC2Hl from...

Dermal exposure to sulfur mustard causes inflammation and tissue injury. This is associated with changes in expression of antioxidants and eicosanoids which contribute to oxidative stress and toxicity. In the present studies we analyzed mechanisms regulating expression of these mediators using an in vitro skin construct model in which mouse keratinocytes were grown at an air-liquid interface an...

n,n-dichloropolystyrene sulfonamide as a decontaminant was synthesized in 5 steps from styrene monomer. styrene was first polymerized. then, sulfonation reaction was performed by h2so4 (c) followed by chlorination with pocl3 obtain chlorosulfonated polystyrene. amidification reaction was then applied to get sulfonamide resin. sulfonamide resin was treated with sodium hypochloride to obtain n,n-...

Sulfur mustard (SM) is a bifunctional alkylating agent with a long history of use as a chemical weapon. Although its last military use is dated for the eighties of the last century, a potential use in terroristic attacks against civilians remains a significant threat. Thus, improving medical therapy of mustard exposed individuals is still of particular interest. PARP inhibitors were recently br...

A case histories course was introduced into the CEE curriculum at University of Louisville in fall 2004, to address various specialties and to synthesize what the students from various specializations learned in different courses. The course, patterned after a course taught by Dr. Ralph B. Peck at the University of Illinois, satisfies many ABET course outcomes and educational objectives. By inv...

N,N-dichloropolystyrene sulfonamide as a decontaminant was synthesized in 5 steps from styrene monomer. Styrene was first polymerized. Then, sulfonation reaction was performed by H2SO4 (c) followed by chlorination with POCl3 obtain chlorosulfonated polystyrene. Amidification reaction was then applied to get sulfonamide resin. Sulfonamide resin was treat...

Telematics applications play an essential role in the dissemination of environmental information and environmental measures. This contribution gives an overview of the applications of environment telematics in Europe as a result of two projects which were performed on an international level. The analysis covers the situation in EC countries as well as in CEE countries, with an emphasis on regio...
