Journal ArticleDOI
Surface effects on the magnetic properties of ultrafine cobalt particles
Marc Respaud,J.M. Broto,H. Rakoto,A. R. Fert,Luc Thomas,Bernard Barbara,Marc Verelst,Etienne Snoeck,Pierre Lecante,A. Mosset,J. Osuna,T. Ould Ely,Catherine Amiens,Bruno Chaudret +13 more
TL;DR: In this article, two colloids (Coll-I and Coll-II) have been obtained by changing the organometallic concentration in the polymer and the particle size deduced from analyses of the magnetic susceptibilities and magnetization curves are consistent with those measured by high-resolution transmission electronic microscopy (HRTEM).
Journal ArticleDOI
Ligand-stabilized ruthenium nanoparticles: synthesis, organization, and dynamics.
Cheng Pan,Katrin Pelzer,Karine Philippot,Bruno Chaudret,Fabrice Dassenoy,Pierre Lecante,Marie-José Casanove +6 more
TL;DR: A catalytic transformation of thiols into disulfides has been observed which involves oxidative addition ofThiols on the ruthenium surface which leads to agglomerated particles or particles dispersed in the solution, both displaying a mean size near 2--3 nm and an hcp structure.
Journal ArticleDOI
Multimillimetre-large superlattices of air-stable iron–cobalt nanoparticles
Céline Desvaux,Catherine Amiens,Peter Fejes,Philippe Renaud,Marc Respaud,Pierre Lecante,Etienne Snoeck,Bruno Chaudret +7 more
TL;DR: This work reports the first direct preparation in solution of multimillimetre-sized three-dimensional compact superlattices of nanoparticles, comprising 15-nm monodisperse FeCo particles that adopt an unusual short-range atomic order that transforms into body-centred-cubic on annealing at 500 ∘C.
Journal ArticleDOI
Influence of organic ligands on the stabilization of palladium nanoparticles
Esther Ramirez,Susanna Jansat,Karine Philippot,Pierre Lecante,Montserrat Gómez,Anna M. Masdeu-Bultó,Bruno Chaudret +6 more
TL;DR: In this article, it was shown that good ligands lead to stable spherical nanoparticles of small size (near 2 nm) whereas the protective effect of HDA depends on the amount of ligand added as a result of equilibria present at the surface of the particles as monitored by solution NMR spectroscopy.
Journal ArticleDOI
Synthesis and Characterization of CoO, Co3O4, and Mixed Co/CoO Nanoparticules
Marc Verelst,Teyeb Ould Ely,Catherine Amiens,Etienne Snoeck,Pierre Lecante,Alain Mosset,Marc Respaud,Jean Marc Broto,Bruno Chaudret +8 more
TL;DR: Very small nanometric oxide particles (CoO and Co3O4, around 2 nm in diameter) well dispersed inside a polymer matrix were prepared by solid-state oxidation of a metallic colloid precursor (1.6 nm).
