An important issue in chlorine drinking water disinfection is the generation from natural organic matter (NOM) of disinfection by-products (DBPs), especially trihalomethanes (THMs). The THMs generation can be limited by reducing the levels of NOM prior to ...
Organohalide respiration (previously named as dehalorespiration) is a process during which microbes derive energy by the reductive dehalogenation of chlorinated organic pollutants and use them as terminal electron acceptors, hence helping in environmental ...
Chemical modification of phage libraries has allowed the in vitro evolution of ligands having properties not provided by natural polypeptides. The development of novel and more diverse chemical reactions on phage was hampered by the lack of analytical meth ...
We previously reported the synthesis and the antimycobacterial activity of 4-(7,7-dimethyl-7H-furo[3,2-f]chromen-2-yl)pyridine. From this result, we sought to design simple synthetic accesses to related structures allowing the preparation of a diverse set ...
Enhanced reductive dehalogenation is an attractive treatment technology for in situ remediation of chlorinated solvent DNAPL source areas. Reductive dehalogenation is an acid-forming process with hydrochloric acid and also organic acids from fermentation o ...
Simulation of biodegradation of chlorinated solvents in dense non-aqueous phase liquid (DNAPL) source zones requires a model that accounts for the complexity of processes involved and that is consistent with available laboratory studies. This paper describ ...
Kinetics, products, and pathways of 17 alpha-ethinylestradiol (EE2) transformation during chlorination of water with and without bromide (Br-) were studied to evaluate the effect of chlorination on the fate of steroid estrogens. Br- can be important for th ...
Kinetic and spectroscopic analyses were performed to gain information about the mechanism of atom-transfer radical reactions catalyzed by the complexes [RuCl2Cp*(PPh3)] and [RuClCp*(PPh3)2] (Cp*=pentamethylcyclopentadienyl), in the presence and in the abse ...
The presence of iodinated disinfection by-products (I-DBPs) in drinking water poses a potential health concern since it has been shown that I-DBPs are generally more genotoxic and cytotoxic than their chlorinated and brominated analogs. I-DBPs are formed d ...
A method for the Friedel-Crafts-type insertion reaction of acetylene with acid chlorides in chloroaluminate ionic liquids is presented. The use of Ionic liquids not only serves to avoid the use of carbon tetrachloride or 1,2-dichloroethane but also suppres ...
