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…

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…

Influence of Magnesium Substitution on the Basic Properties of Hydroxyapatites

Sarah Diallo-Garcia, Danielle Laurencin, Jean-Marc Krafft, Sandra Casale, Mark E. Smith, Hélène Pernot, Guylène Costentin

Magnesium-substituted hydroxyapatites (HAP) have been prepared to evaluate the influence of cationic substitution on the surface basic properties of HAP. Despite successful introduction of some of the magnesium cations into the HAP structure (as evidenced by XRD, infrared, and Raman), no influence of…

Influence of the temperature on the reduction mechanism of concentrated nitric acid on a silicon-enriched austenitic stainless steel

I. Bahtit, N. Gruet, B. Puga, X.R. Nóvoa, Cyril Thomas, V. Vivier

Corrosion of silicon-enriched stainless steel in nitric acid strongly depends on the temperature of the electrolyte. Therefore, the reduction reaction of nitric acid on this material was investigated from 40 to 107 °C. For the first time, the autocatalytic reduction mechanism of nitric acid…
