On the Comprehensive Precipitation of Hydroxyapatites Unraveled by a Combined Kinetic–Thermodynamic Approach

Corentin Reynaud, Cyril Thomas, Guylène Costentin

The present study combines experimental and theoretical approaches to investigate the competitive precipitation of calcium phosphates (CaPs) in aqueous solution in order to understand and control both the structural and textural properties of the synthesized hydroxyapatites (HAps). Some of the…

Clicked BODIPY‐Fullerene‐Peptide Assemblies: Studies of Electron Transfer Processes in Self‐Assembled Monolayers on Gold Surfaces

Jad Rabah, Houssein Nasrallah, Karen Wright, Isabelle Gérard, Hélène Fensterbank, Thi Tuyet Van Bui, Jérôme Marrot, Thu-Trang Tran, Anam Fatima, Minh-Huong Ha-Thi, Rachel Méallet, Gotard Burdzinski, Gilles Clavier, Souhir Boujday, Hubert Cachet, Catherine Debiemme-Chouvy, Emmanuel Maisonhaute, Anne Vallée, Emmanuel Allard

Two BODIPY‐C60‐peptide assemblies were synthesized by CuAAC reactions of BODIPY‐C60 dyads and a helical peptide functionalized with a terminal alkyne group and an azide group, respectively. The helical peptide within these assemblies was functionalized at its other end by a disulfide group,…

Copper incorporated mesoporous materials: synthesis, characterization and catalytic activity in benzaldehyde reduction

O. Zekri, A. Saadi, F. Launay, C. Calers, C. Rabia

Copper substituted mesoporous silica materials (Cu–HMS-n), with a variety of Si/Cu atomic ratios (n) ranging from 50 to 100, were synthesized by the one-pot sol–gel method using dodecylamine as template. These materials were characterized by X-ray diffraction, N2 adsorption-desorption, transmission…

Vanadium-Substituted Phosphomolybdic Acids for the Aerobic Cleavage of Lignin Models-Mechanistic Aspect and Extension to Lignin

Louay Al-Hussaini, Franck Launay, Elena Galvez

This work deals with the aerobic oxidative cleavage of CC and CO bonds catalyzed by the Keggin-type phosphovanadomolybdic acid (H 6 [PMo 9 V 3 O 40 ], noted H 6 PV 3). The latter was synthesized by an adapted hydrothermal procedure classically used for lower vanadium content and was tested as a…

Flavonols and 3-hydroxychromones: new applications for a class of environment-sensitive fluorescent molecules

Stefano Protti, Alberto Mezzetti

Flavonols are naturally-occuring molecules that exhibit interesting fluorescence properties. Thanks to an excited-state intramolecular proton transfer, to specific interactions with their molecular environment and to ground-state proton transfer reactions, very often a dual or even triple…

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…

Solvent effects on the vibrational spectrum of 3-hydroxyflavone

Ari Paavo Seitsonen, Abdenacer Idrissi, Stefano Protti, Alberto Mezzetti

3-hydroxyflavone (3HF) is a widely studied molecule that acts as a simplified prototype of biological, more complex flavonoids. Its solvation mechanism is still under investigation. Here we report a joint experimental and simulation study of the vibrational properties of 3HF in gas phase and in…
