Monitoring by in situ neutron diffraction of simultaneous dehydration and Ni2+ mobility in partially exchanged NaY zeolites

Florence Porcher, Jean-Louis Paillaud, Lucia Gaberova, Gilles André, Sandra Casale, Pascale Massiani

Powder neutron diffraction is used to follow structural changes occurring during heat and vacuum assisted dehydration of 3 wt% nickel exchanged NaY. The structures determined from Rietveld refinement confirm the nickel ion displacement from the supercages and sodalite cages towards hexagonal prisms…

Influence of the temperature on the reduction mechanism of concentrated nitric acid on a silicon-enriched austenitic stainless steel

I. Bahtit, N. Gruet, B. Puga, X.R. Nóvoa, Cyril Thomas, V. Vivier

Corrosion of silicon-enriched stainless steel in nitric acid strongly depends on the temperature of the electrolyte. Therefore, the reduction reaction of nitric acid on this material was investigated from 40 to 107 °C. For the first time, the autocatalytic reduction mechanism of nitric acid…

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…

Polyol-mediated syntheses of crystalline nanosized manganese oxides

Guiqiang Diao, François Chau, Jean-Yves Piquemal, Emmanuel Briot, Souad Ammar, Mickaël Sicard, Sophie Nowak, Patricia Beaunier, Hélène Lecoq, P. Decorse, Lin Yu

Potassium-type birnessite and lithium-containing manganese oxides were prepared by the polyol process. The Mn(III)/Mn(IV) mixed-valencies compounds are obtained through the controlled reduction of potassium permanganate in a basic water–diethylene glycol mixture at moderate temperature and very…

Behavior of cellobiose in iron-containing solutions: towards a better understanding of the dominant mechanism of degradation of cellulosic paper by iron gall inks

Alice Gimat, Anne-Laurence Dupont, Hélène Lauron-Pernot, Sabrina M Paris, Véronique Rouchon, Pascale Massiani

Cellobiose, a dimer of glucose wearing a glycosidic bond as in cellulose, was used as model molecule to understand the chemical degradation pathways taking place in iron gall inks impregnated papers. Experiments were carried out in liquid phase at 80 degrees C to study the effects of pH and of the…
