Mechanical modelling of microwave sintering and experimental validation on an alumina powder

Maxence Renaux, Damien Méresse, Julien Pellé, Anthony Thuault, Céline Morin, Christelle Nivot, Christian Courtois

Microwave sintering (MW) allows fast heating (≤30 min) and densification of ceramic materials, like alumina Al2O3. In order to predict the final material properties (density, size and grain size) the mechanical SOVS (Skorohold Olevsky Viscous Sintering) model is adapted and validated for…

From Metal-Organic Framework Powders to Shaped Solids: Recent Developments and Challenges

Bakytzhan Yeskendir, Jean-Philippe Dacquin, Yannick Lorgouilloux, Christian Courtois, Sébastien Royer, Jérémy Dhainaut

Metal-organic frameworks represent a class of porous materials which developed considerably over the past few years. Their highly porous structure makes them outperforming conventional adsorbents in hot topics such as dihydrogen and methane storage, and carbon dioxide capture. Their consequent…

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…

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…
