Development of a thermodynamic approach to assist the control of the precipitation of hydroxyapatites and associated calcium phosphates in open systems

Corentin Reynaud, Cyril Thomas, Sandra Casale, Sophie Nowak, Guylène Costentin

The understanding of the precipitation mechanisms of calcium phosphates (CaPs) remains extremely challenging despite its fundamental interest for material sciences and its practical implications in medicine, paleosciences, and chemistry, especially for heterogeneous catalysis. The competitive…

Electrical surface properties of nanoporous alumina membranes: influence of nanochannels’ curvature, roughness and composition studied via electrokinetic experiments

Ali Vakilinejad, Emmanuelle Dubois, Laurent Michot, Marie Jardat, Didier Lairez, Serge Durand-Vidal, Clément Guibert, Nicolas Jouault

Among classical nanoporous oxide membranes, anodic aluminum oxide (AAO) membranes, made of non-connected, parallel and ordered nanochannels, are very interesting nanoporous model systems widely used for multiple applications. Since most of these applications involve local phenomena at the…

Formation of Activated Biomolecules by Condensation on Mineral Surfaces – A Comparison of Peptide Bond Formation and Phosphate Condensation

Thomas Georgelin, Maguy Jaber, Houssein Bazzi, Jean-François Lambert

Many studies have reported condensation reactions of prebiotic molecules, such as the formation of peptide bonds between amino acids, to occur to some degree on mineral surfaces. We have studied several such reactions on the same divided silica. When drying steps are applied, the equilibria of…

The Mosaic Structure of Zeolite Crystals

Zhengxing Qin, Georgian Melinte, Jean-Pierre Gilson, Maguy Jaber, Krassimir Bozhilov, Philippe Boullay, Svetlana Mintova, Ovidiu Ersen, Valentin Valtchev

Zeolites are widely used in many commercial processes, mostly as catalysts or adsorbents. Understanding their intimate structure at the nanoscale is the key to control their properties and design the best materials for their ever increasing uses. Herein, we report a new and controllable fluoride…

Esterification of fatty acids with alcohols over niobium phosphate

Iria A.L. Bassan, Danielle R. Nascimento, Rosane A.S. San Gil, M.I. Pais da Silva, Carla R. Moreira, Wilma A. Gonzalez, Arnaldo C. Faro, T. Onfroy, Elizabeth R. Lachter

The aim of this study is the evaluation of niobium catalysts (niobic acid, niobium phosphate) in the esterification reactions of fatty acids (C12-C18) with alcohols (methanol, ethanol, butanol). The catalysts were characterized by different techniques (N2 adsorption/desorption, XRD, FTIR, FTIR of…
