On the graphical analysis of the impedance response of passive electrodes

Mai T.T. Tran, Oumaïma Gharbi, Mark E Orazem, Bernard Tribollet, Mireille Turmine, Vincent Vivier

The analysis of the capacitive behavior of a passive electrode is often a difficult subject because the response obtained by electrochemical impedance spectroscopy (EIS) is characterized by a non-ideal behavior that we try to model by using a constant phase element (CPE) [1, 2]. In doing so, both…

Potent antimicrobial peptides against Legionella pneumophila and its environmental host, Acanthamoeba castellanii.

Margot Schlusselhuber, Vincent Humblot, Sandra Casale, Christophe Méthivier, Julien Verdon, Matthias Leippe, Jean-Marc Berjeaud

Legionella pneumophila, the major causative agent of Legionnaires' disease, is most often found in the environment in close association with free-living amoebae, leading to persistence, spread, biocide resistance, and elevated virulence of the bacterium. In the present study, we evaluated the…

Unraveling the Direct Decomposition of NO x over Keggin Heteropolyacids and Their Deactivation Using a Combination of Gas-IR/MS and In Situ DRIFT Spectroscopy

Josefine Schnee, Laurent Delannoy, Guylène Costentin, Cyril Thomas

Keggin heteropolyacids (HPAs) have been known to be efficient NOx absorbers for many years, and to decompose a significant fraction of the NOx species pre-absorbed at 100-150 °C into harmless N2 and O2 upon rapid heating to 450 °C. However, this capability of Keggin HPAs to directly decompose NOx…

Stability of Binary SAMs Formed by omega-Acid and Alcohol Functionalized Thiol Mixtures

Frederik Tielens, Vincent Humblot, Claire-Marie Pradier, Monica Calatayud, Francesc Illas

A simple model is presented to describe the mixing process of acid- and alcohol-terminated thiol self-assembled monolayers (SAMs) on Au(111). It was found that the low-concentration acid-terminated SAMs are enriched in acid thiol compared with the original solution from which the SAM is made. Due…

Design of TiO2/Au nanoparticle films with controlled crack formation and different architectures using a centrifugal strategy

Abdelhafed Taleb, Frederic Mesguich, Thomas Onfroy, Xue Yanpeng

Here we present an approach to design hybrid nanocomposite films based on TiO2/Au nanoparticles using centrifugation processes. The prepared nanocomposite films have been characterized by different techniques such as FEGSEM, TEM, BET and XRD. Furthermore it is demonstrated that centrifugal force…

Synthesis of Well-Defined Dawson-Type Poly(N,N-diethylacrylamide) Organopolyoxometalates

Jennifer Lesage de la haye, Patricia Beaunier, Laurent Ruhlmann, Bernold Hasenknopf, Emmanuel Lacôte, Jutta Rieger

An organotin-substituted Dawson-type phosphotungstate was covalently linked to a trithiocarbonate group by postfunctionalization methods. This organopolyoxometalate led to a series of polyoxometalate (POM)–poly(N,N-diethylacrylamide) hybrids in a controlled way through reversible addition–…

Application of Arrhenius law to DP and zero-span tensile strength measurements taken on iron gall ink impregnated papers: relevance of artificial ageing protocols

Véronique Rouchon, Oulfa Belhadj, Maroussia Duranton, Alice Gimat, Pascale Massiani

Iron gall inks (IGI) were largely used for writing until the nineteenth century. Under certain circumstances, they provoke a substantial degradation of their cellulosic support.It was shown in a previous works thatc ombination of oxygen and iron largely impacts cellulose chain breaking occurring in…
