Evaluation of silicate minerals for acid neutralization during bioremediation of high concentrations of chlorinated ethenes

Chloroethenes are the most prevalent groundwater contaminants in developed countries. They accumulate in the environment as a dense non aqueous phase liquid (DNAPL) which acts as a long term source of contamination. Enhanced in situ anaerobic bioremediatio ...

Photocatalytic discoloration of aqueous malachite green solutions by UV-illuminated TiO2 nanoparticles under air and nitrogen atmospheres: effects of counter-ions and pH

César Pulgarin, Christophe Roussel

Under air atmosphere, the photocatalytic discoloration of malachite green (MG) aqueous solutions (a triphenylmethane dye) in the presence of TiO2 and UV light followed an oxidative pathway, involving an N-demethylation process evidenced by a blue shifting ...

Computational study of drug binding to the membrane-bound tetrameric M2 peptide bundle from influenza A virus

Matteo Dal Peraro

The M2 protein of influenza A virus performs the crucial function of transporting protons to the interior of virions enclosed in the endosome. Adamantane drugs, amantadine (AMN) and rimantidine (RMN), block the proton conduction in some strains, and have b ...

Two Positive Solutions of a Quasilinear Elliptic Dirichlet Problem

Charles Stuart

For a class of second order quasilinear elliptic equations we establish the existence of two non-negative weak solutions of the Dirichlet problem on a bounded domain, Omega. Solutions of the boundary value problem are critical points of C-1-functional on H ...

Electrochemical behavior of ammonia at Ni/Ni(OH)2 electrode

Christos Comninellis, Agnieszka Kapalka

The electrochemical oxidation of ammonia was investigated on a Ni/Ni(OH)(2) electrode prepared by potential cycling of a Ni electrode in 1 M NaClO4. It was found that oxidation of ammonia is strongly pH dependent and proceeds mainly at pH values above 7. T ...

Ammonia oxidation to nitrogen mediated by electrogenerated active chlorine on Ti/PtOx-IrO2

Christos Comninellis, Agnieszka Kapalka, Nina-Luisa Michels

The electrochemical oxidation of ammonia (NH3 and/or NH4+) in the presence of chloride was investigated on a Ti/PtOx-IrO2 electrode. It was shown that ammonia is effectively removed from solution via electrogenerated active chlorine. Based on mass balances ...
