Study of neck formation and densification in porous hydroxyapatite ceramics using thermal conductivity measurements

David Stanley Smith, Pierre Lefeuvre, Maxence Renaux, Benoît Nait-Ali, Anne Leriche

Neck formation and densification during sintering have strong effects on the thermal conductivity of a porous ceramic body. This has been described by an analytical model using grain conductivity, grain size, pore fraction and particle – particle contact area as input parameters. It has been tested...

Topological Data Structure: The Fast Marching Example

Sofian Toujja, Thierry Bay, Hakim Belhaouari, Laurent Fuchs

This article lies in the field of front propagation algorithms on a surface represented by triangle meshes. An implementation of the fast marching algorithm using a topological structure, the generalized maps or gmaps, as the data structure of the mesh is presented. G-maps have the advantage of...

Stabilization of the generalized Rao‐Nakra beam by partial viscous damping

Mohammad Akil, Zhuangyi Liu

In this paper, we consider the stabilization of the generalized Rao‐Nakra beam equation, which consists of four wave equations for the longitudinal displacements and the shear angle of the top and bottom layers and one Euler–Bernoulli beam equation for the transversal displacement. Dissipative...

How are alkali-activated materials impacted by incorporating low viscosity organic liquids?

Charles Reeb, Catherine A. Davy, Matthieu de Campos, Jérôme Hosdez, Christel Pierlot, Cyrille Albert-Mercier, David Lambertin

This research determines an adequate alkali-activated material (AAM) for the incorporation of huge amounts (20 or 40% vol) of low viscosity organic liquids (LVOL), e.g. for waste stabilization/solidification. The selected AAM are either based on high-Ca content blast furnace slag, or on low Ca-...

Mg2+, Sr2+, Ag+, and Cu2+ co-doped beta-tricalcium phosphate: Improved thermal stability and mechanical and biological properties

Nicolas Somers, Florian Jean, Marie Lasgorceix, Giovanni Urruth, Sandra Balvay, Claire Gaillard, Laurent Gremillard, Anne Leriche

β-tricalcium phosphate (β-TCP, β-Ca3(PO4)2) is an attractive biomaterial for bone repair applications. However, its sintering and mechanical properties are limited by a problematic phase transition to α-TCP. Cationic doping of β-TCP is able to postpone the formation of α-TCP allowing higher...

Effect of dimensional variations on the manufacturing process and the 3D shrinkage ratio of stereolithographic dental alumina ceramics.

Corentin Denis, Lieven Robberecht, Jérôme Delattre, Etienne Deveaux, Jean-Christophe Hornez, Marion Dehurtevent

The purpose of the present study was to evaluate the influence of height and length variations of alumina ceramics manufactured by stereolithography on deformations caused by the manufacturing process and on the 3D shrinkage ratio to control the final dimensions and improve the adaptation of...

Fabrication of doped β-tricalcium phosphate bioceramics by Direct Ink Writing for bone repair applications

Nicolas Somers, Florian Jean, Marie Lasgorceix, Nicolas Preux, Cathy Delmotte, Laurent Boilet, Fabrice Petit, Anne Leriche

β-tricalcium phosphate (β-TCP, β-Ca3(PO4)2) is one of the most attractive biomaterials for bone regeneration and β-TCP macroporous scaffolds are very promising for both cell proliferation and mechanical support. The Additive Manufacturing (AM) process called Direct Ink Writing (DIW), based on the...

Improvement of Metal-Doped β-TCP Scaffolds for Active Bone Substitutes via Ultra-Short Laser Structuring

Íris Soares, Lamborghini Sotelo, Ina Erceg, Florian Jean, Marie Lasgorceix, Anne Leriche, Maja Dutour Sikirić, Katarina Marušić, Silke Christiansen, Albena Daskalova

Various efforts have been made to develop antibacterial biomaterials capable of also sustaining bone remodulation to be used as bone substitutes and reduce patient infection rates and related costs. In this work, beta-tricalcium phosphate (β-TCP) was chosen due to its known biocompatibility and use...
