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…

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…

Crystal-chemistry and reactivity of fibrous amphiboles of environmental and health interest, Cristallochimie et réactivité de surface d'amphiboles fibreuses d'intérêt environnemental et sanitaire

Alessandro Pacella

This work concerns the physico-chemical and structural characterisation of mineral fibres (asbestos) and the comprehension of the chemical and molecular mechanisms which are responsible of the development of human pathologies specific to their inhalation. In particular, in this work we performed a…, Ce travail de thèse concerne la caractérisation physico-chimique et structurale de fibres minérales et la compréhension de mécanismes chimiques et moléculaires qui peuvent amorcer des pathologies spécifiques relatives à leur inhalation.

Preparation, characterization, and hydrogenation activity of new Rh 0 –MCM-41 catalysts prepared from as-synthesized MCM-41 and RhCl 3

Maya Boutros, Georges Moarbess, Thomas Onfroy, Franck Launay

Impregnation of as-synthesized MCM-41 silica by ethanolic solutions of rhodium(III) chloride was tested as an alternative to its introduction into the synthesis gel to get, after calcination and reduction by H2, highly dispersed metal(0) nanoparticles throughout the mesopores network. Rh(III) and…

Efficient transformation of cyclohexanone to ε-caprolactone in the oxygen-aldehyde system over single-site titanium BEA zeolite

Katarzyna Pamin, Jacek Gurgul, Grzegorz Mordarski, Yannick Millot, Jean-Philippe Nogier, Laetitia Valentin, Stanislaw Dzwigaj

TixSiBEA zeolites prepared by a two-step post-synthesis method are applied in the liquid-phase Baeyer-Villiger oxidation of cyclohexanone to ε-caprolactone in the oxygen-aldehyde system. Such method of ε-caprolactone synthesis offers the application of milder reaction conditions with the catalytic…

Promoting Ag/Al2O3 Performance in Low-Temperature H2-C3H6-SCR by Thermal Pretreatment of γ-Alumina in Water

Tesnim Chaieb, Laurent Delannoy, Catherine Louis, Cyril Thomas

The present work highlights for the first time that a thermal treatment of γ-Al2O3 in water at 80 °C for 24 h prior to Ag deposition (Ag/Al2O3-OH) leads to a drastic enhancement of H2-C3H6-SCR performance at low temperature. This enhancement is attributed to the higher NOx coverage on Ag/Al2O3-OH…

Loop-stabilized BAB triblock copolymer morphologies by PISA in water

Pauline Biais, Patricia Beaunier, François Stoffelbach, Jutta Rieger

A straightforward strategy to synthesize in water, loop-stabilized particles via PISA is developed. These particular structures can in theory be obtained through the synthesis of amphiphilic BAB triblock copolymers, starting from a hydrophilic middle block A, which is chain extended in an aqueous…
