Electron Transfer at the Metal Oxide/Electrolyte Interface: A Simple Methodology for Quantitative Kinetics Evaluation

Iban Azcarate, Cyrille Costentin, Christophe Méthivier, Christel Laberty-Robert, Alexis Grimaud

While quantitative models exist for measuring rate constants for electron exchange at the surface of semiconductors to or from redox couples in solution, their use is very limited for studying transition metal oxide electrodes. Taking advantage of the possibility of tuning the doping level of WO 3…

Fast and potent bactericidal membrane lytic activity of PaDBS1R1, a novel cationic antimicrobial peptide

Luz N Irazazabal, William F Porto, Isabel C.M. Fensterseifer, Eliane S.F. Alves, Carolina Matos, Antônio C.S. Menezes, Mário R Felício, Sónia Gonçalves, Nuno Santos, Suzana M Ribeiro, Vincent Humblot, Luciano M Lião, Ali Ladram, Octavio L Franco

Antimicrobial peptides (AMPs) are promising candidates for the development of future antibiotics. In an attempt to increase the efficacy of therapeutic AMPs, computer-based design methods appear as a reliable strategy. In this study, we evaluated the antimicrobial efficiency and mechanism of action…

Heterogeneous Fenton-like reactions in natural soils and sediments at neutral pH with O2 as oxidant

Elora Bourbon, Frederic Averseng, Thierry Allard, Pierre Le Pape, Sylvie Nélieu, Xavier Carrier, Guillaume Morin, Elodie Guigon, Fulvia Baratelli, Sophie Ayrault

Heterogeneous Fenton-like processes using O2 as oxidant and iron(II) minerals as substrate is a rapidly growing research field with important implications especially for in-situ organic pollutant degradation in natural media. These reactions can be conducted at neutral pH and several minerals are…

Electrochemical and spectroscopic evidences of corrosion inhibition of bronze by a triazole derivative

Ahmed Dermaj, Najat Hajjaji, Suzanne Joiret, Kamal Rahmouni, Abdellah Srhiri, Hisasi Takenouti, Vincent Vivier

The electrochemical behavior of the bronze (Cu–8Sn in wt%) was investigated in 3% NaCl aqueous solution, in presence and in absence of a corrosion inhibitor, the 3-phenyl-1,2,4-triazole-5-thione (PTS). The inhibiting effect of the PTS was evidenced for concentrations higher than 1 mM for the…

Urea electro-oxidation byproducts impact on NiO/NiOOH anode performance studied by operando electrochemical impedance spectroscopy

Sophia Akkari, Vincent Vivier, Carlos M Sánchez-Sánchez

With significant quantities of urea (CO(NH2)2) being worldwide produced and its presence at high concentration in urine, simultaneous treatment of urea effluents and hydrogen production by paired electrolysis represents a very attractive approach in circular economy. Urea electro-oxidation on Ni-…

Controlling the reproducibility of Coulomb blockade phenomena for gold nanoparticles on an organic monolayer/silicon system

L Caillard, S Sattayaporn, A-F Lamic-Humblot, S Casale, P Campbell, y J Chabal, Olivier Pluchery

Two types of highly ordered organic layers were prepared on silicon modified with an amine termination for binding gold nanoparticles (AuNPs). These two grafted organic monolayers (GOMs), consisting of alkyl chains with seven or 11 carbon atoms, were grafted on oxide-free Si(111) surfaces as tunnel…

Two- and Four-Electrode Configurations for Contactless Reinforced Concrete Corrosion Monitoring

B. Díaz, X.R. Nóvoa, C. Pérez, A. Pintos, Vincent Vivier

The paper addresses the need for a fast and reliable method for field monitoring reinforced concrete structures. A proof of concept is presented where a noncontact procedure provides quantitative information on the concrete resistivity and reinforcement corrosion rate. A Wenner-type probe is…
