Gold, Silver, and Iron Oxide Nanoparticle Incorporation into Silk Hydrogels for Biomedical Applications: Elaboration, Structure, and Properties

Cristina Belda Marín, Christophe Egles, Vincent Humblot, Yoann Lalatonne, Laurence Motte, Jessem Landoulsi, Erwann Guénin

Silk fibroin (SF) is a versatile material with biodegradable and biocompatible properties, which make it fit for broad biomedical applications. In this context, the incorporation of nanosized objects into SF allows the development of a variety of bionanocomposites with tailored properties and…

Homogeneous and Heterogeneous Catalysis for the Synthesis of Cyclic and Polymeric Carbonates from CO2 and Epoxides: A Mechanistic Overview

Guillaume Laugel, Catarina Rocha Carvalho, Pascale Massiani, Thomas Onfroy, Franck Launay

The utilization of CO2 for the production of useful chemicals is nowadays considered as a promising way to contribute to the reduction of greenhouse gases in the atmosphere, while valorizing at the same time this widely available resource. The synthesis of cyclic carbonates and polycarbonates via…

Pseudo-automorphisms with no invariant foliation

Eric Bedford, Serge Cantat, Kyounghee Kim

We construct an example of a birational transformation of a rational threefold for which the first and second dynamical degrees coincide and are $>1$, but which does not preserve any holomorphic (singular) foliation. In particular, this provides a negative answer to a question of Guedj. On our…

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…

Development of a hybrid coating associating biomimetic hydroxyapatite and natural antibiotics with antibacterial properties, Développement d’un revêtement hybride aux propriétés antibactériennes associant hydroxyapatite biomimétique et antibiotiques naturels

Estelle Palierse

This thesis aims to develop a hybrid coating based on biomimetic hydroxyapatite and natural antibacterial molecules, with the goal to add antibacterial properties and enhance the osseointegration of titanium (Ti6Al4V) implants. Four natural biologically active molecules (BAMs) were tested,…, Cette thèse porte sur l’élaboration de revêtements de surface hybrides composés d’hydroxyapatite biomimétique et de molécules antibactériennes naturelles, dans le but d’ajouter des propriétés antibactériennes et d’améliorer l’ostéointégration d’implants en titane (Ti6Al4V). Quatre molécules…

HgTe Nanocrystal Inks for Extended Short‐Wave Infrared Detection

Bertille Martinez, Julien Ramade, Clément Livache, Nicolas Goubet, Audrey Chu, Charlie Gréboval, Junling Qu, William L Watkins, Loic Becerra, Erwan Dandeu, Jean Louis Fave, Christophe Méthivier, Emmanuelle Lacaze, Emmanuel Lhuillier

Short‐wave infrared (IR) detection is currently driven by InGaAs technology which has limited the perspective of cost effectiveness and consequently slows the development of IR sensors. Since organic electronics are ineffective in this wavelength range, an alternative to conductive polymers is the…

Interaction of proteins with chemically controlled surfaces for biosensor development, Interactions des protéines avec des surfaces chimiquement contrôlées pour le développement de bio-senseurs

Victor Lebec

In this work we studied protein adsorption on chemically well-controlled surfaces. The focus is put on linking physico-chemical properties of surfaces (hydrophobicity/charge) to the structural properties of the adsorbed proteins. To this end, alkyl thiols differing by their end group were used to…, Dans ce travail, nous étudions l’adsorption de protéines sur des surfaces chimiquement contrôlées. Le but est d’établir le lien entre les propriétés physico-chimiques de la surface (hydrophobicité /charge) et la structure physique de protéines. Des couches auto-assemblées de thiols ayant des…

Rheo-SAXS study of a shear-thinning hydrogel containing clay nanoplatelets

Claire Hotton, Guylaine Ducouret, Juliette Sirieix-Plénet, Thomas Bizien, Clément Guibert, Pierre Levitz, Laurent Michot, Natalie Malikova

Shear-induced orientation of clay nanoplatelets within a physically cross-linked hydrogel based on ionenes, positively charged polyelectrolytes, is studied here. Small angle X-ray scattering measurements (SAXS) are performed under shear within a Couette cell cylinder (rheo-SAXS). As the SAXS signal…

Toward new proton exchange batteries based on ionic liquid electrolyte: Metal hydride electrode / electrolyte coupling

Nesrine Chaabene, J. Zhang, Mireille Turmine, E. Kurchavova, Vincent Vivier, F. Cuevas, M. Mateos, M. Latroche, J. Monnier

The voltage of an alkaline electrolyte-based battery is limited by the narrow electrochemical stability window of water. As an alternative to water, protic ionic liquid (IL)-based electrolytes have shown excellent conducting properties as well as a wide electrochemical stability window, and can…

HRTEM and STEM-HAADF characterisation of Au-TiO2 and Au-Al2O3 catalysts for a better understanding of the parameters influencing their properties in CO oxidation

L. Delannoy, R.L. Chantry, S. Casale, Z.Y. Li, Yves Borensztein, C. Louis

Gold catalysts supported on titania (Au-TiO2) and alumina (Au-Al2O3) were prepared by deposition- precipitation with urea and then activated before characterisation and reaction in CO oxidation, either by calcination in air at 500 1C or reduction under H2 at 300 1C. Gold nanoparticles with average…
