Bulk TiO2 vs alternative Ti-based photocatalysts for the mild aerobic oxidation of alcohols, Masse de TiO2 versus photocatalyseurs alternatifs à base de titane de l’oxydation ménagée et aérobie d’alcools

Diaa Obaid

A series of metal oxides semiconductors, including commercially available TiO2 or synthesized mesoporous samples, were tested as photocatalysts for the aerobic mild oxidation of alcohols in acetonitrile under UV. Benzyl alcohol, used as a reference, was oxidized mainly into benzaldehyde. Best yield…, Des oxydes semi-conducteurs, en particulier TiO2 commercialement disponible ou des échantillons mésoporeux synthétisés, ont été testés comme photocatalyseurs de l'oxydation ménagée et aérobie d'alcools dans l'acétonitrile sous UV. L'alcool benzylique a été oxydé principalement…

Effect of nanocrystallization on the structure and the magnetic properties of Nd–Fe–Co–Al–B glassy alloy

Lotfi Bessais, C. Djéga-Mariadassou, P. Beaunier

Nd 40 Fe 30 Co 15 Al 10 B 5 bulk amorphous prepared by high energy milling shows a coercivity of 650kA∕m with a Curie temperature of 645K. The controlled nanocrystallization enhances the coercivity to 1600kA∕m and the remanence ratio is equal to 0.59. The coexistence of two crystalline magnetic…

An Experimental and Theoretical Approach to Investigate the Effect of Chain Length on Aminothiol Adsorption and Assembly on Gold

Erin Bedford, Vincent Humblot, Christophe Méthivier, Claire-Marie Pradier, Frank Gu, Frederik Tielens, Souhir Boujday

Despite the numerous studies on the self-assembled monolayers (SAMs) of alkylthiols on gold, the mechanisms involved, especially the nature and influence of the thiol-gold interface are still under debate. In this work the adsorption of aminothiols on Au(111) surfaces has been studied by using…

Deciphering the Adsorption Mechanisms of RGD Subunits: L-Aspartic Acid on Cu(110)

Roberta Totani, Christophe Méthivier, Hervé Cruguel, Claire-Marie Pradier, Vincent Humblot

In this work we present a detailed surface science characterization of L-Aspartic acid adsorption on a Cu(110) surface. We replaced the traditional sublimation method to obtain molecular films by dosing aspartic acid directly from an aqueous solution through an Electrospray Ionization (ESI) device…
