Diagnosis of the Diatom Community upon Biofilm Development on Stainless Steels in Natural Freshwater

Caroline Richard, Smita Mitbavkar, Jessem Landoulsi

This paper reports the development of biofilms on stainless steels (SS) upon exposure in a natural freshwater ecosystem for about six months and focuses on the composition of diatom populations. By using environmental scanning electron microscopy (ESEM) technique, we provide a detailed description…

Adsorption of Amino Acids and Peptides on Metal and Oxide Surfaces in Water Environment: A Synthetic and Prospective Review

D. Costa, L. Savio, Claire-Marie Pradier

Amino acids and peptides are often used as “model” segments of proteins for studying their behavior in various types of environments, and/or elaborating functional surfaces. Indeed, though the protein behavior is much more complex than that of their isolated segments, knowledge of the binding mode…

Inorganic Phosphate and Nucleotides on Silica Surface: Condensation, Dismutation, and Phosphorylation

Thomas Georgelin, Maguy Jaber, Thomas Onfroy, Aaron-Albert Hargrove, France Costa-Torro, Jean-François Lambert

We explore the reactivity of inorganic monophosphate ions (Pi) and 5′-adenosine monophosphate (AMP), adsorbed onto amorphous silica separately or together. This question has relevance for prebiotic chemistry scenarios and, more generally, for biomedical applications involving biomolecule adsorption…

Développement d’un microsystème électrochimique pour l’étude de micro-objets circulants dans un canal microfluidique, Development of an electrochemical microsystem for the study of circulating micro-objects in a microfluidic channel

Ines Amokrane

Dans le cadre de cette thèse, l’objectif est de caractériser des micro-objets circulant dans un microcanal à l’aide de techniques électrochimiques. Dans le but de concevoir et de fabriquer un tel système, plusieurs méthodes et techniques sont nécessaires. Tout d’abord, le microsystème est constitué…, In this thesis, the aim is to characterise micro-objects flowing in a microchannel using electrochemical techniques. In order to design and fabricate such a system, several methods and techniques are required. Firstly, the microsystem consists of PDMS microchannels and thin film microelectrodes.…

Les Hydroxyapatites, un système basique atypique modulable par la synthèse : vers l'identification des sites actifs, Hydroxyapatites, an atypical basic system tuneable by synthesis: toward the identification of active sites

Sarah Diallo Garcia

Les Hydroxyapatites (HAp) sont des matériaux basiques dont les propriétés catalytiques atypiques, notamment leur très bonne sélectivité pour la transformation de l'éthanol en n-butanol, sont encore mal rationnalisées. La modulation de leur paramètres de synthèse ainsi leur aptitude à la…, Hydroxyapatites (HAp) are basic materials whose atypical catalytic properties, in particular their high selectivity in n-butanol from ethanol's conversion, are yet to be rationalised. Modulation of their synthesis parameters as well as their ability toward substitution allowed us to use their…

On the chemistry of the conversion coatings

Oumaïma Gharbi, Kevin Ogle, Junsoo Han

A conversion coating is an inorganic or organic–inorganic hybrid surface film conveying specific desirable functions to a material, formed by a spontaneous reaction between the material and an electrolyte. This chapter reviews the fundamental physical chemistry of the conversion coating process and…

Toward new proton exchange batteries based on ionic liquid electrolyte: Metal hydride electrode / electrolyte coupling

Nesrine Chaabene, J. Zhang, Mireille Turmine, E. Kurchavova, Vincent Vivier, F. Cuevas, M. Mateos, M. Latroche, J. Monnier

The voltage of an alkaline electrolyte-based battery is limited by the narrow electrochemical stability window of water. As an alternative to water, protic ionic liquid (IL)-based electrolytes have shown excellent conducting properties as well as a wide electrochemical stability window, and can…

Deciphering the Adsorption Mechanisms of RGD Subunits: L-Aspartic Acid on Cu(110)

Roberta Totani, Christophe Méthivier, Hervé Cruguel, Claire-Marie Pradier, Vincent Humblot

In this work we present a detailed surface science characterization of L-Aspartic acid adsorption on a Cu(110) surface. We replaced the traditional sublimation method to obtain molecular films by dosing aspartic acid directly from an aqueous solution through an Electrospray Ionization (ESI) device…
