Adsorption of chiral molecules in oxide-supported heterogeneous catalysts : a model approach, Adsorption de molécules chirales sur catalyseurs hétérogènes supportés sur oxyde : une approche modèle

Elisa Meriggio

Enantioselective heterogeneous catalysis is a method of choice for the synthesis of enantiopure chiral products. One current approach involves the modification of a metal surface by a chiral modifier. Despite its great potential, only a small number of successful systems have been developed so far.…, La catalyse asymétrique hétérogène est une méthode de choix pour la synthèse de composés chiraux énantiopurs. Une approche courante implique la modification d'une surface métallique par un inducteur chiral. Malgré son potentiel, seul un petit nombre de systèmes ont été mis au point jusqu…

Gold Nanoparticles on Oxide-Free Silicon-Molecule Interface for Single Electron Transport

Louis Caillard, Oliver Seitz, Philip M. Campbell, Rachel P. Doherty, Anne-Félicie Lamic-Humblot, Emmanuelle Lacaze, Yves J. Chabal, Olivier Pluchery

Two different organic monolayers were prepared on silicon Si(111) and modified for attaching gold nanoparticles. The molecules are covalently bound to silicon and form very ordered monolayers sometimes improperly called self-assembled monolayers (SAM). They are designed to be electrically…

Oxidation of gold metal particles supported on TiO2: an FTIR study by means of low-temperature CO adsorption

Hr. Klimev, Katia Fajerwerg, K. Chakarova, L. Delannoy, C. Louis, K. Hadjiivanov

Two Au/TiO2 samples with different gold loadings (0.7 and 4.0 wt.% Au) were prepared by deposition-precipitation with urea and calcined at 673 K. TEM revealed gold particles of 3.2 and 3.9 nm for the 0.7 and 4.0 wt.% samples, respectively. The samples were subjected to different red-ox treatments…

Interaction between Orange Carotenoid Protein and mesoporous silica : from spectroscopic investigations to photoactive nanodevices, Interaction entre la Orange Carotenoid Protein et la silice mésoporeuse : des investigations spectroscopiques aux nanodispositifs photo-actifs

Silvia Leccese

This thesis deals with the study of interactions between the Orange Carotenoid Protein and mesoporous silica SBA-15, aiming to the development of photoactive nano-devices. The photoactive Orange Carotenoid Protein (OCP) is a protein involved in photo-protective responses in cyanobacteria. It…, Ce projet de thèse concerne l’étude des interactions entre la Orange Carotenoid Protein (OCP) et la silice mésoporeuse SBA-15, visant à la mise au point de nanodispositifs photo-actifs. La OCP est une protéine photo-active impliquée dans la photoprotection des cyanobactéries. Il implique la…

Direct grafting of ethylene sulfide onto silicic acid magadiite

Michelle Menezes de Oliveira, Marcia Maria Fernandes, Maria Gardennia Fonseca, Edson Cavalcanti da Silva Filho, Antonio Gouveia de Souza, Fabrice Gaslain, Maguy Jaber

Acidic magadiite (HMag) was directly reacted with ethylene sulfide (ES) under various controlled conditions producing an intercalated hybrid silicate (MagS). The sodium, acidic and modified magadiites were characterized using elemental analysis, thermogravimetric analysis (TGA/DTG), infrared…

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…

A DNA biosensor based on peptide nucleic acids on gold surfaces

Eva Mateo-Marti, C. Briones, Claire-Marie Pradier, Jose A. Martin-Gago

We present a DNA biosensor based on self assembled monolayers (SAMs) of thiol-derivatized Peptide nucleic acid (PNA) chains adsorbed on gold surfaces for recognizing complementary ssDNA. PNA molecules tend to realign their molecular axes parallel to the surface normal and form SAMs on gold surfaces…
