b-tricalcium phosphate (b-TCP, b-Ca 3 (PO 4 ) 2 ) is one of the most attractive biomaterials for bone repair since it shows an excellent biological compatibility, osteoconductivity, and resorbability. It is already commercialized under granules or preforms for bone filling but there are still some...

Novel Portland cement matrices incorporating a gamma -MnO2 /Ag2O hydrogen/tritium getter -structure changes and trapping performance

Sandy Lanier, Catherine Davy, Cyrille Albert-Mercier, Oriane Farcy, Céline Cau Dit Coumes, David Lambertin

This study investigates novel Portland cement-based mortars, developed for hydrogen/tritium trapping and radioactive waste immobilization. They incorporate a γ-MnO2/Ag2O getter powder at 10% wt (i.e. 6.8 to 7.1% vol). Compared to former patented materials, no drying or heat treatment of the...

Morphological, structural, electrical, and piezoelectric analysis of hydrothermally grown ZnO nanowires on various substrates

Abderrahmane Hamdi, Ahmad Hamieh, Mervat Alamri, Karim Dogheche, M.M. Saj Mohan, Rachel Desfeux, Denis Remiens, El Hadj Dogheche

In this present work, we have successfully fabricated a piezoelectric structure based on ZnO nanowires (ZnO NWs) using a simple, low cost and environmentally friendly hydrothermal method. This structure forms the basis to fabricate vertically integrated nanogenerator device. This paper attempts to...

Mechanical and optical properties of MgAl2O4 ceramics and ballistic efficiency of spinel based armour

Caroline Gajdowski, Raffaele d'Elia, Norbert Faderl, Judith Böhmler, Yannick Lorgouilloux, Sébastien Lemonnier, Anne Leriche

This study was devoted to the understanding of the influence of MgAl2O4 ceramic properties on their ballistic performances. By modifying the processing parameters, ceramics with different microstructures were obtained. Among them, a transparent MgAl2O4 spinel with an in-line transmission between 77...
