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…

Design of Bifunctional Catalysts Based on Bea Zeolites for Tandem Processes with Participation of Ethanol

N. O. Popovych, O. V. Larina, S. M. Orlyk, P. I. Kyriienko, S. O. Soloviev, S. Dzwigaj

The results from the creation of BEA zeolite catalysts, containing heteroelements of Ta(Nb) and modified with d-metals (Ag, Cu, Zn), for processes involving ethanol, are presented. The activity of Ag/BEA in the selective reduction of nitrogen oxides (NOx) with ethanol is due to the presence of…

Factors impacting protein adsorption on layer-by-layer assembled stimuli-responsive thin films

A. Osypova, C.-A. Fustin, C.-M. Pradier, Jessem Landoulsi, S. Demoustier-Champagne

Studying the stimuli-response of polyelectrolyte multilayers (PEMs) towards protein adsorption requires coping with the multiplicity of factors influencing interfacial processes. In this study, we report the design of a nanostructured stimuli-responsive coating based on the sequential layer-by…

Acidic Osteoid Templates the Plywood Structure of Bone Tissue

Marc Robin, Chakib Djediat, Arnaud Bardouil, Niki Baccile, Camille Chareyron, Ivo Zizak, Peter Fratzl, Mohamed Selmane, Bernard Haye, Isabelle Genois, Jean‐marc Krafft, Guylène Costentin, Thierry Azaïs, Franck Artzner, Marie‐madeleine Giraud-Guille, Paul Zaslansky, Nadine Nassif

Bone is created by osteoblasts that secrete osteoid after which an ordered texture emerges, followed by mineralization. Plywood geometries are a hallmark of many trabecular and cortical bones, yet the origin of this texturing in vivo has never been shown. Nevertheless, extensive in vitro work…

Development of heterogeneous chemoenzymatic catalysts based on Metal-Organic Framework for the selective and eco-friendly amination of alcohols, Développement de catalyseurs hétérogènes chimioenzymatiques basés sur l'utilisation de polymères de coordination poreux dédiés à l'amination éco-compatible d'alcools

Yifan Zan

The aim of this work was to develop a heterogeneous chemoenzymatic catalyst based on the use of Metal-Organic Frameworks (MOFs) as support for the eco-friendly amination of alcohols in a one-pot cascade synthesis. The cascade process is divided into two steps: an alcohol oxidation chemically…, L'objectif de ce travail était de développer un catalyseur chimio-enzymatique hétérogène basé sur l'utilisation de polymères de coordination poreux (ou Metal-Organic Framework: MOF) comme supports pour l'amination durable d'alcools à travers un procédé en cascade réalisé en une…
