Thermal Behavior of d -Ribose Adsorbed on Silica: Effect of Inorganic Salt Coadsorption and Significance for Prebiotic Chemistry

Mariame Akouche, Maguy Jaber, Emilie-Laure Zins, Marie-Christine Maurel, Jean-Francois Lambert, Thomas Georgelin

Understanding ribose reactivity is a crucial step in the “RNA world” scenario because this molecule is a component of all extant nucleotides that make up RNA. In solution, ribose is unstable and susceptible to thermal destruction. We examined how ribose behaves upon thermal activation when adsorbed…

The role of the synthesis method in the structure formation of cobalt aluminate

Thomas Onfroy, Wen-Cui Li, Ferdi Schueth, Helmut Knoezinger

Cobalt aluminate (spinel) was prepd. via two synthesis routes firstly a co-pptn. method and secondly a nanocasting method. The surface chem. of these materials was characterized by IR-spectroscopy of the surface hydroxyl groups and of coordinatively unsatd. (cus) cations (Al and Co) by carbon…

Ethylene production from diluted bioethanol solutions

Ilenia Rossetti, Matteo Compagnoni, Giorgia de Guido, Laura A. Pellegrini, Gianguido Ramis, Stanislaw Dzwigaj

Ethylene production by ethanol dehydration has been investigated over a set of zeolites with BEA structure in acidic form (HAlBEA). The effect on Ni addition (up to 0.03 g/g (3 mass%)) is explored as a means to improve ethylene selectivity limiting the formation of heavier byproducts. The reaction…

Polyoxotungstates-stabilized gold nanoparticles: how to transfer from an aqueous suspension to CH3CN ?, Nanoparticules d'or stabilisées par des polyoxotungstates : comment passer d'une suspension aqueuse à CH3CN ?

Jean-Baptiste Harlé, Élise Péruse, Jimika Hassanaly, Dalil Brouri, Anna Proust, Audrey Denicourt-Novicky, Alain Roucoux, Anne Gauvin-Bialecki, Richard Villanneau

The present study aims to evaluate available methods for preparing suspensions of gold nanoparticles stabilized by polyoxometalates (POMs@AuNPs) in CH3CN, a solvent commonly used in oxidation reactions. POMs@AuNPs are successfully synthesized in CH3CN using three different approaches: i) in situ…

Depuis la nuit des temps, l’homme a fabriqué et utilisé des produits cosmétiques. De la Gaule à l’Egypte, en passant par l’Empire Romain et la Grèce antique, les hommes et les femmes s’appliquaient sur le visage et le corps des produits naturels ou transformés (huiles, poudres, mixtures, laits, etc…, Since the dawn of time, man has manufactured and used cosmetic products. From Gaul to Egypt, passing through the Roman Empire and ancient Greece, men and women applied to the face and body of natural or processed products (oils, powders, mixtures, milks, etc.) in order to embellish oneself, to heal…

Nanoscale heterostructures of covalent intermetallics should give birth to a wide range of interface-driven physical and chemical properties. Such a level of design however remains unattainable for most of these compounds, due to the difficulty to reach a crystalline order of covalent bonds at the…
