BACKGROUND p-Nitrophenol (PNP) occurs as contaminants of industrial effluents and it is the most important environmental pollutant and causes significant health and environmental risks, because it is toxic to many living organisms. Nevertheless, the information regarding PNP degradation pathways and their enzymes remain limited. OBJECTIVE To evaluate the efficacy of the Pseudomonas Putida 127...
The main thrust of this investigation is the development of models of distributed atomic polarizabilities for the treatment of induction effects in molecular mechanics simulations. The models are obtained within the framework of the induced dipole theory by fitting the induction energies computed via a fast but accurate MP2/Sadlej-adjusted perturbational approach in a grid of points surrounding...
Introduction of a polyfluoroalkyl group into aromatic compounds was achieved by Friedel-Crafts reaction using (1-chloro-1-hydroperfluoroalkyl) sulfides 1, and the subsequent desulfurizing-difluorination of the resulting product using IF5 / Et3N-nHF. Perfluoroethyl, 1,1,2,2,3,3-hexafluoropropyl, and 1,1,2,2,3,3,4,4,5,5-decafluoropentyl groups were introduced to various aromatic compounds by this...
The photostability of aromatic compounds in the presence of air is significantly improved through perfluoroalkylation of the corresponding aromatic cores and use of polyfluorinated solvents despite higher O(2) concentration in polyfluorinated solvents than in hydrocarbon solvents.
