Influence of dopants on thermal stability and densification of β-tricalcium phosphate powders

Nicolas Somers, Florian Jean, Marie Lasgorceix, Hugo Curto, Giovanni Urruth, Anthony Thuault, Fabrice Petit, Anne Leriche

In this work, β-tricalcium phosphate (β-TCP) is doped with Mg2+ and Sr2+ in order to postpone the problematic β-TCP → α-TCP transition occurring from 1125 °C. Indeed, this phase transition occurs with a large lattice expansion during sintering causing microcracks and a reduced shrinkage leading to…

Influence of a macroporous β-TCP structure on human mesenchymal stem cell proliferation and differentiation in vitro

Shaan Chamary, Liliana Grenho, Maria Helena Fernandes, Franck Bouchart, Fernando Jorge Monteiro, Jean-Christophe Hornez

This work aims at studying the links between a porous scaffold in β-TCP and its impact on cell differentiation and proliferation in vitro. β-TCP was synthesized by aqueous precipitation. The shaping methods were chosen for their ability to generate original structures with the potential to…

The complete discretization of the dual mixed method for the heat diffusion equation in a polygonal domain

Luc Paquet, Réda Korikache

The purpose of this paper is to prove a priori error estimates for the completely discretized problem of the dual mixed method for the non-stationary heat diffusion equation in a polygonal domain of R2. Due to the geometric singularities of the domain, the exact solution is not regular in the…

Etude des propriétés piézoélectriques du polymère biosourcé PLA pour la récupération d'énergie vibratoire, Piezoelectric properties of biobased poly(L-lactide)stretched films for energy harvesting applications

Mohamed Aymen Ben Achour

La potentialité des films PLA produits par extrusion et étirés uniaxialement par MDO à partir des grades industriels a été investiguée pour la récupération d’énergie vibratoire par effet piézoélectrique. Une technique de caractérisation du coefficient piézoélectrique plus adaptée aux films…, The potentiality of PLA films produced by extrusion and uniaxial stretching by MDO of industrial grades has been investigated for the energy harvesting by piezoelectric transformation. A piezoelectric coefficient characterization technique suitable for polymer films was tested and validated on a…

New Developments and Biomaterials in Reconstruction of Defects of the Alveolar Ridge in Implant Surgery: Part 1—Biomaterials

Thomas Wojcik, Vincent Hornez, Jean-Christophe Hornez, Joël Ferri

Bone is a tissue that has the ability of self-regeneration leading this healing process in most of the cases to a fully morphologic and functional regeneration. However, in some situations, its healing capabilities can be surpassed, and bone grafts are frequently required for implant surgery.…

Hybrid additive/subtractive manufacturing system to prepare dense and complicated ceramic parts

Fabrice Petit, Qirong Chen, Enrique Juste, Marie Lasgorceix, Anne Leriche

As the conventional binder jetting method is limited in terms of achievable density and finish surface, a new concept of hybrid subtractive/additive manufacturing system has been recently developed. The system relies on a modified binder jetting machine which integrates a slurry-based deposition…

Effect of spray drying treatment on the optical properties of Mg–Al spinel ceramics

Robin Stocky, Judith Boehmler, Sébastien Lemonnier, Pierre Gibot, Yannick Lorgouilloux, Anne Leriche

In recent years, Mg–Al spinel ceramic has been in the spotlight due to its large transparency range and goodmechanical properties. The aim here, was to control the state of agglomeration of powder to improve densifi-cation behaviour and consequently optical and mechanical properties of the ceramics…
