Beneficial effect of gelatin on iron gall ink corrosion

Alice Gimat, Anne Michelin, Pascale Massiani, Véronique Rouchon

Iron gall Inks corrosion causes paper degradation (browning, embrittlement) and treatments were developed to tackle this issue. They often include resizing with gelatin to reinforce the paper and its cellulosic fibers (of diameter approx. 10 µm). This work aimed at measuring the distribution of ink…

EIS investigation of zinc dissolution in aerated sulfate medium. Part I: bulk zinc

Chantal Cachet, F. Ganne, Georges Maurin, J. Petitjean, Vincent Vivier, Robert Wiart

The kinetics of anodic dissolution and corrosion of zinc are investigated by electrochemical impedance spectroscopy in sulfate medium for various surface preparation conditions and different experimental procedures. A new version of the reaction model, which was established previously, accounts…

Tuning the Growth Mode of 3D Silver Nanocrystal Superlattices by Triphenylphosphine

Karima Ouhenia-Ouadahi, Amandine Andrieux-Ledier, Johannes Richardi, Pierre-Antoine Albouy, Patricia Beaunier, Peter Sutter, Eli Sutter, Alexa Courty

Here, we show that the residual presence of reaction products markedly influences the growth mode of 3D superlattices made of silver nanocrystals. The silver nanocrystals (5 or 6 nm in diameter) are synthesized via the reduction of a silver triphenylphosphine complex in the presence of thiols. The…

Deciphering the role and nature of phosphate species at the surface of stainless steel immersed in phosphoric acid solutions

I. Liascukiene, M. Ben Salah, Ph. Refait, L. Dhouibi, C. Methivier, J. Landoulsi, M. Jeannin

We investigate the evolution of the surface of a highly alloyed stainless steel (Sanicro 28) upon immersion in aqueous phosphoric acid solutions. For this purpose, both short-(few hours) and long-term immersion (several days) were carried out. A detailed analysis of XPS spectra allowed a…

Conception raisonnée de catalyseurs bifonctionnels : élaboration de catalyseurs Pt0/zéolithe-Alumine, Rational design of bifunctional catalysts : development of Pt0/zeolithe-alumina catalysts

Olfa Ben Moussa

Les catalyseurs bifonctionnels pour l’hydrocraquage nécessitent à la fois des sites acides de Brønsted et des sites métalliques. L’intimité entre sites acides et sites métalliques peut donc influer sur l’activité et la sélectivité de la réaction. Nous nous sommes proposés d’explorer l’effet de la…, Bifunctional hydrocracking catalysts require both Brønsted acid sites and metal sites. Hence, the intimacy between acid sites and metal sites can influence the activity and selectivity of the reaction. We intended to explore the effect of metal sites-acid sites distance on the conversion of n-…

On the use of a constant phase element (CPE) in electrochemistry

Samantha Michelle Gateman, Oumaïma Gharbi, Hercílio Gomes De Melo, Kieu Ngo, Mirelle Turmine, Vincent Vivier

Several techniques can be used to experimentally determine the interfacial capacitance of an electrode, which is a crucial parameter used for quantifying the efficiency of supercapacitors. However, the values obtained from cyclic voltammetry can be significantly different from those extracted from…

Direct Observation of the Surface Topography at High Temperature with SEM

Renaud Podor, X. F Le Goff, Joseph Lautru, H.P. Brau, Mathias Barreau, Xavier Carrier, Jerôme Mendonça, Dorian Nogues, Antoine Candeias

High-temperature scanning electron microscopy allows the direct study of the temperature behavior of materials. Using a newly developed heating stage, tilted images series were recorded at high temperature and 3D images of the sample surface were reconstructed. By combining 3D images recorded at…
