Experimental and modeling-based analysis of reaction pathways on catalysts for natural gas engines under periodic lean/rich oscillations

Oliver Kröcher, Davide Ferri, Moyu Wang

Methane (CH4) has the prospective of becoming one of the major energy carriers for heavy-duty mobility, but its catalytic abatement remains a challenge. CH4 abatement reaction pathways were analyzed using targeted periodic lean/rich oscillations, which res ...

Multidisciplinary Preclinical Investigations on Three Oxamniquine Analogues as New Drug Candidates for Schistosomiasis

Ursula Röthlisberger, François Louis Mouvet

Schistosomiasis is a disease of poverty affecting millions of people. Praziquantel (PZQ), with its strengths and weaknesses, is the only treatment available. We previously reported findings on three lead compounds derived from oxamniquine (OXA), an old ant ...

Electrochemically Controlled Proton-Transfer-Catalyzed Reactions at Liquid-Liquid Interfaces: Nucleophilic Substitution on Ferrocene Methanol

Hubert Girault, Pekka Eero Peljo, Liang Qiao

The generation of α-ferrocenyl carbocations from ferrocenyl alcohols for SN1 substitution at the water–organic solvent interface is initiated by the transfer of protons into the organic phase. The proton flux, and hence the reaction rate, can be controlled ...

Ethanol internal steam reforming in intermediate temperature solid oxide fuel cell

Jan Van Herle, Stefan Diethelm

This study investigates the performance of a standard Ni-YSZ anode supported cell under ethanol steam reforming operating conditions. Therefore, the fuel cell was directly operated with a steam/ethanol mixture (3 to 1 molar). Other gas mixtures were also u ...

Development of a natural gas reaction mechanism for engine simulations based on rapid compression machine experiments using a multi-objective optimisation strategy

Daniel Favrat, Stefan Heyne

The ignition delay times of CH4/C2H6/C3H8 mixtures representative of an average natural gas composition have been measured in a rapid compression machine (RCM) at the University of Lille. The pressure at the end of compression (EOC) varied from 13 to 21 ba ...

Decrease of lead concentrations in the Western Mediterranean atmosphere during the last 20 years

Thomas Robin

Concentrations of lead (Pb) in the atmospheric aerosol were monitored in 198687, 199293, 1995, 199798 and 20032005 at a North-Western Mediterranean coastal sampling station. After the implementation of antipollution policies on automotive Pb in the second ...

Influence of the Composition of Natural Organic Matter on Pb Bioavailability to Microalgae

Cristina Lamelas

The current work examines the effects of model allochtonous (humic substances) and autochtonous (microbial polysac charides) natural organic matter (NOM) on Pb speciation and bioaccumulation. The results demonstrated that polysaccharides, in particular alg ...
