Synthèse et fonctionnalisation de nanobâtonnets d’or enrobés de silice AuNR@SiO2 pour des applications aux biointerfaces, Synthesis and functionalization of silica coated gold nanorod AuNR@SiO2 for biointerfaces applications

Vincent Pellas

Les nanobâtonnets d’or sont des particules plasmoniques présentant des propriétés optiques intéressantes. En particulier, la résonance plasmonique de surface localisée (LSPR) sensible à l’environnement local des particules, permet leur utilisation comme transducteurs de phénomènes d’interactions…, Gold nanorods are plasmonic nanoparticles with interesting optical properties. In particular, the localized surface plasmon resonance (LSPR), sensitive to the local environment of the particles, allows their use as transducers of molecular interaction phenomena. This property makes those…

Tuning Model Drug Release and Soft-Tissue Bioadhesion of Polyester Films by Plasma Post-Treatment

Vishal T. Mogal, Chaw Su Yin, Richard O’rorke, Souhir Boujday, Christophe Méthivier, Subbu S. Venkatraman, Terry W. J. Steele

lasma treatments are investigated as a post-production method of tuning drug release and bioadhesion of poly(lactic-co-glycolic acid) (PLGA) thin films. PLGA films were treated under varying conditions by controlling gas flow rate, composition, treatment time, and radio frequency (RF) power. In…

Hierarchical collagen-hydroxyapatite nanostructures designed through layer-by-layer assembly of crystal-decorated fibrils

Elodie Colaço, Dalil Brouri, Nesrine Aissaoui, Pauline Cornette, Vincent Dupres, Rute F Domingos, Jean-François Lambert, Emmanuel Maisonhaute, Karim El Kirat, Jessem Landoulsi

A comprehensive understanding of the mechanism by which type I collagen (Col) interacts with hydroxyapatite nanoparticles (Hap NPs) in aqueous solutions is a pivotal step for guiding the design of biologically relevant nanocomposites with controlled hierarchical structure. In this paper we use a…

Facile synthesis of palladium nanowires by a soft templating method

Prem Siril, Anaïs Lehoux, Laurence Ramos, Patricia Beaunier, Hynd Remita

Very long and thin monocrystalline Pd nanowires were synthesized by decomposition using hydrazine vapour treatment of Pd2(DBA)3 confined in the oil phase of a hexagonal mesophase. The mesophase is composed of toluene-swollen tubes, doped with the Pd precursor, stabilized by a monolayer of…

Characterisation and Reactivity of Oxygen Species at the Surface of Metal Oxides

M. Anpo, Guylène Costentin, E. Giamello, H. Lauron-Pernot, Z. Sojka

Surface reactive oxygen species play a fundamental role in selective oxidation and combustion reactions catalyzed by metal oxides. Unravelling the nature of these transient species, and understanding the details of both their electronic structure and reactivity has been for decades one of the prime…

Investigation of the plate-impact method as a precursor of physical phenomena and chemical processes, L'étude de la méthode de l'impact par plaque comme précurseur des phénomènes physiques et des processus chimiques

Maya Mounir Daou

This manuscript aims at characterizing a new device based on a plate impact on a liquid surface to generate cavitation and evaluate its potential to induce chemical reactions. The device is composed of a reactor containing a liquid that a piston hits due to pressure difference. This impact…, Ce manuscrit a pour but d'étudier un nouveau dispositif générateur de cavitation dont le potentiel favorable à l'intensification de réactions chimiques est évalué. Ce dispositif est constitué d'une plaque mobile qui frappe un liquide contenu dans un réacteur. L'impact génère une…
