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…

Organo-NOx formation-decomposition as the origin of the changes in the low temperature NO-TPD profile in the presence of n-decane on Ag/γ-Al2O3

Kinga Malinger, Juliette Blanchard, Rachel P. Doherty, Cyril Thomas

The NOx desorption profiles obtained in O2-He and n-C10-O2-He were compared on γ-Al2O3 and Ag/γ-Al2O3. On Ag/γ-Al2O3, the low-temperature NOx desorption profiles obtained in n-C10-O2-He were significantly different from those obtained in O2-He. In particular, at 190-220 °C excess release of NO,…

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…
