Optimisation du procédé d'impression par stéréolithographie de phosphate tricalcique béta, Optimisation of the stereolithography printing process of tricalcium phosphate

Chloé Goutagny

Les technologies de fabrication additive permettent la production rapide d’objets de forme complexe et trouvent un intérêt dans le domaine des soins à la santé, en particulier pour la fabrication d’implants osseux synthétiques. Les biocéramiques sont des matériaux de choix pour ce type d’implant.…, The additive manufacturing technologies enable the fast production of objects with a complex shape and are particularly interesting in the medical field and the manufacture of synthetic bone implants. Bioceramics are materials of choice for this type of implant. Amongst them the hydroxyapatite and…

Topological Optimization of Piezoelectric Structures for Low-frequency Energy Harvesting Applications

Madiha Yessari, Mohamed Rguiti, Abdelowahed Hajjaji, Najoua Fangachi, Abdezzahid Arbaoui

Recovering energy from ambient vibrating resources has been the subject of considerable research studies in the last decade. However, the vibrations found in the environment correspond to low frequencies, often below 200 Hz, and for small-scale applications and if the excitation is sinusoidal, the…

Subdivisions of Ring Dupin Cyclides Using Bézier Curves with Mass Points

Lionel Garnier, Lucie Druoton, Jean-Paul Becar, Laurent Fuchs, Géraldine Morin

The paper deals in the Computer-Aided Design or Computer-Aided Manufacturing domain with the Dupin cyclides as well as the Bézier curves. It shows that the same algorithms can be used either for subdivisions of ring Dupin cyclides or Bézier curves. The Bézier curves are described with mass points…

Influence of cetyltrimethylammonium bromide and hydroxide ions on the interfacial tension and stability of emulsions of dodecane in aqueous silicate solutions

Matthieu Bertin, Donatien Gomes Rodrigues, Christel Pierlot, Cyrille Albert-Mercier, Catherine Davy, David Lambertin, Véronique Rataj

This manuscript provides an understanding of the emulsification mechanisms of a model alkane (dodecane) in concentrated aqueous sodium silicate solutions, for e.g. formulating alkane/geopolymer composites for varied applications. To this purpose, we assume that silicate oligomers stabilize the…

Efficiency of the emulsification of organic liquids in alkali-activated materials for radioactive waste encapsulation purposes

Charles Reeb, David Lambertin, Catherine Davy, Cyrille Albert Mercier, Christel Pierlot

The encapsulation of a pure mineral oil (20%vol.) was successfully performed in alkali-activated materials (AAM), either based on metakaolin or blast furnace slag precursors. Surfactants are required to efficiently stabilize the emulsion of oil. Rheological characterizations of fresh pastes…

Comparaison de techniques de frittage non-conventionnelles appliquées à la zircone et l'hydroxyapatite nanométriques, Comparison of non-conventional sintering techniques applied to nanometric zirconia and hydroxyapatite

Pierre Lefeuvre

L’amélioration de la compréhension des phénomènes de densification de poudres céramiques a conduit au développement de nouvelles technologies de frittage impliquant l’application d’une pression, d’un champ électrique ou de micro-ondes. Ces différentes techniques conduisent à des chemins de…, Better understanding of densification of ceramic powders led to the development of new sintering technologies using pressure, an electric field or microwaves. These new techniques have their own densification path and allow to obtain denser ceramics with a finer microstructure. A question that is…

Apport de la RMN dans les matériaux vitreux, Contribution of NMR in vitreous materials

Cyrille Albert-Mercier

Mes travaux de recherche concernent 2 thèmes principaux : i) le dopage de différents verres et leur analyse structurale – soit par le phosphore dans ce cas les verres sont utilisés comme substituts osseux appelés bioverres appartenant au système SiO2-Na2O-CaO-P2O5 pour améliorer la bioactivité ou…, My research work concerns 2 main themes: i) the doping of different glasses and their structural analysis – either by phosphorus in this case the glasses are used as bone substitutes called bioglasses belonging to the SiO2-Na2O-CaO-P2O5 system to improve the bioactivity or by nitrogen to increase…

A User-Oriented Local Coastal Flooding Early Warning System Using Metamodelling Techniques

Déborah Idier, Axel Aurouet, François Bachoc, Audrey Baills, José Daniel Betancourt, Fabrice Gamboa, Thierry Klein, Andrés F. López-Lopera, Rodrigo Pedreros, Jérémy Rohmer, Alexandre Thibault

Given recent scientific advances, coastal flooding events can be properly modelled. Nevertheless, such models are computationally expensive (requiring many hours), which prevents their use for forecasting and warning. In addition, there is a gap between the model outputs and information actually…

Stability properties of dissipative evolution equations with nonautonomous and nonlinear damping

Serge Nicaise

In this paper, we obtain some stability results of (abstract) dissipative evolution equations with a nonautonomous and nonlinear damping using the exponential stability of the retrograde problem with a linear and autonomous feedback and a comparison principle. We then illustrate our abstract…
