Butanethiol was used in ultraviolet-initiated thiol-ene reaction with canola and corn oils to produce sulfide-modified vegetable oils (SMVO). The crude SMVO product was successfully purified by solvent extraction, vacuum evaporation, and silica gel chromatography. The SMVO products were characterized by

The oxidative stability of self-assembled monolayer (SAM) of thiols on silver was examined with matrix-assisted laser desorption ionization (MALDI) time-of-flight (TOF) mass spectrometry (MS). A benzenesulfinate (BS) monolayer on silver was also prepared and investigated with MALDI-TOF-MS and surface-enhanced Raman

Indicators of free-radical or oxidant-mediated responses were quantified in channel catfish, Ictalurus punctatus, exposed to the organophosphorus herbicide DEF and its metabolite, n-butyl mercaptan (nBM). The activities of the antioxidant enzymes superoxide dismutase (SOD), glutathione peroxidase (GPX) and catalase did
