Extraction and Physicochemical Characterization of an Environmentally Friendly Biopolymer: Chitosan for Composite Matrix Application

Meryiem Derraz, Abdelaziz Elouahli, Chouaib Ennawaoui, Mohamed Aymen Ben Achour, Abdelkader Rjafallah, El Mehdi Laadissi, Hamza Khallok, Zineb Hatim, Abdelowahed Hajjaji

Chitosan, which is a derivative of chitin, is particularly popular due to its biodegradable and renewable nature. However, the properties of chitosan can be inconsistent due to the extraction process and its natural origin, which poses a challenge to its use in composite materials as a matrix. The…

Energy harvesting by uniaxially-stretched poly(lactide) films at low tensile strain frequencies for powering wearable sensors: experimental results and theoretical extrapolation

Mohamed Aymen Ben Achour, Sophie Barrau, Jean-François Tahon, Mohamed Rguiti, Christian Courtois, Birgit Stubbe, Jean-Marie Raquez, Marie-France Lacrampe, Cédric Samuel

Poly(lactide) (PLA) is an eco-friendly and low-cost polymer with a shear piezoelectricity easily induced by uniaxial stretching and without poling process. These interesting features make PLA as a good candidate to replace the widely-used poly(vinylidene difluoride) (PVDF) piezoelectric polymer, in…

Microwave-assisted debinding of Al2O3 parts printed by stereolithography

Maria Canillas, Florian Jean, Anthony Thuault, Dominique Hautcoeur, Anne Leriche

Complex shapes pieces of Al2O3 can be rapidly shaped by SLA technology. However, debinding and sintering post-shaping steps still involve long working times. Sintering by microwave has been previously studied providing important time-saving in the fabrication processes and finer microstructures.…

Mathematical analysis of a thermodynamically consistent reduced model for iron corrosion

Clément Cancès, Claire Chainais-Hillairet, Benoît Merlet, Federica Raimondi, Juliette Venel

We are interested in a reduced model for corrosion of iron, in which ferric cations and electrons evolve in a fixed oxide layer subject to a self-consistent electrostatic potential. Reactions at the boundaries are modeled thanks to Butler-Volmer formulas, whereas the boundary conditions on the…

Préparation par fabrication additive de supports de catalyseurs pour la conversion de molécules biosourcées

Méryem Mounaj, Florian Jean, Jeremy Dhainaut, Christian Courtois, Yannick Lorgouilloux

L'objectif de ces travaux est de préparer des supports de catalyseurs en céramique poreuse, telle que l'alumine ou la zircone, via l’utilisation de procédés de fabrication additive permettant d’élaborer des pièces par ajout de matière à partir de fichiers numériques. Dans un premier temps…

On the notion of ground state for nonlinear Schrödinger equations on metric graphs

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

We compare ground states for the nonlinear Schrödinger equation on metric graphs, defined as global minimizers of the action functional constrained on the Nehari manifold, and least action solutions, namely minimizers of the action among all solutions to the equation. In principle, four alternative…
