Poudre apatitique biomimétique en phagothérapie pour lutter contre les biofilms installés lors d’infections ostéoarticulaires, Phage therapy with biomimetic apathetic powder to fight against bone and joints biofilms

Maxime Decodts

Grâce à leurs propriétés biocompatibles, ostéoconductrices et résorbables, les céramiques de phosphate de calcium sont fréquemment utilisées en tant que biomatériaux pour des implants orthopédiques ou encore pour de la régénération osseuse. Cependant, après utilisation de ces biomatériaux, il est..., Thanks to their biocompatible, osteoconductive and resorbable properties, phosphate calcium ceramics are commonly used as biomaterials for orthopaedic implants or for bone regeneration. However, after using these biomaterials, micro-organism may invade them, representing a major source of bone and...

The nonlinear Schrödinger equation on metric graphs, L’équation de Schrödinger non-linéaire sur les graphes métriques

Damien Galant

In this thesis, we investigate the nonlinear Schrödinger equation−∆u + λu = |u|ᵖ⁻²u (NLS)where ∆ := ∑ ∂ᵢᵢ is the Laplacian, p, λ ∈ ℝ and p > 2. The equation isconsidered on open domains of ℝᴺ or, in most chapters, on metric graphs.To begin with, we set the stage in which the following chapters..., Dans cette thèse, nous étudions l'équation de Schrödinger non-linéaire−∆u + λu = |u|ᵖ⁻²u (NLS)où ∆ := ∑ ∂ᵢᵢ est le laplacien, p, λ ∈ ℝ et p > 2.L'équation est considérée sur des ouverts de ℝᴺ ou, dans l'essentiel des chapitres,sur des graphes métriques.Tout d'abord, nous...

Geography of bilinearized Legendrian contact homology

Frédéric Bourgeois, Damien Galant

We study the geography of bilinearized Legendrian contact homology for closed, connected Legendrian submanifolds with vanishing Maslov class in 1-jet spaces. We show that this invariant detects whether the two augmentations used to define it are DGA homotopic or not. We describe a collection of...

Poly(Amino Acid) LbL Multilayers With Embedded Silver and Copper Oxide Nanoparticles as Biocompatible Antibacterial Coatings

Ana‐marija Milisav, Lamborghini Sotelo, Cristina Cantallops-Vilà, Tommaso Fontanot, Ina Erceg, Krunoslav Bojanić, Tomislav Vuletić, Željka Fiket, Maja Ivanić, Silke Christiansen, Edwige Meurice, Maja Dutour Sikirić

Abstract The growing concern over implant‐associated infections motivates the development of novel antibacterial coatings for medical devices as an effective strategy in reducing the occurrence of IAI. Polyelectrolyte multilayers (PEMs) incorporating metal/metal oxide nanoparticles (NPs) as...

Sol-Gel Synthesis of a New Composition of Bioactive Glass

Halima El Bouami, Assia Mabrouk, Cyrille Mercier, Claudine Follet, Ahmed Bachar

Bioactive glasses hold immense promise for tissue engineering and bone regeneration due to their ability to bond with living tissues and stimulate bone growth. This chapter explores the sol-gel method, a versatile technique offering advantages like lower processing temperatures and superior...

New Generation of Glass Materials for Biomedical Applications

Ahmed Bachar, Assia Mabrouk, Cyrille Mercier, Claudine Follet, Franck Bouchart, Arnaud Tricoteaux, Stuart Hampshire

The limited strength of bioglasses has confined their application to non-load-bearing contexts, thus necessitating enhancements in their mechanical properties. A viable approach to surmount this hurdle involves integrating nitrogen into the silicate network of the glass. This outlines the effect of...

An action approach to nodal and least energy normalized solutions for nonlinear Schrödinger equations

Colette De Coster, Simone Dovetta, Damien Galant, Enrico Serra

We develop a new approach to the investigation of normalized solutions for nonlinear Schrödinger equations based on the analysis of the masses of ground states of the corresponding action functional. Our first result is a complete characterization of the masses of action ground states, obtained via...

SPECTRUM ANALYSIS OF THE UNDERLYING OPERATOR FOR A 2D PIEZOELECTRIC BEAM WITH MAGNETIC EFFECT ON AN ANNULAR DOMAIN

Virginie Régnier, Mohammad Akil

The aim is to determine the eigenvalues of locally coupled equations modelling a 2D piezoelectric beam with magnetic effect with only one local viscous damping on an annular domain without geometric conditions. The eigenvalues are proved to lie in a vertical band defined explicitly in terms of the...

Control of the preferentially orientated growth of Sr2TiSi2O8 crystals in a SrO – TiO2 – SiO2 – Al2O3 – K2O parent glass

Oussama Zwein, Marie-Sophie Renoirt, Maurice Gonon, Nicolas Preux, Sandra Abdelouhab, Rıdvan Yildiz, Marc Duquennoy

A polar glass-ceramic containing Sr-fresnoite Sr2TiSi2O8 (STS) as single crystalline phase was developed through the controlled crystallization of a parent glass composition containing SrO, TiO2, SiO2, K2O, and Al2O3. The objective of this work is to obtain a piezoelectric substrate exhibiting a...
