Highly Transparent BaAl4O7 Polycrystalline Ceramic Obtained by Full Crystallization from Glass
Mathieu Allix,Salaheddine Alahrache,Franck Fayon,Matthew R. Suchomel,Florence Porcher,Thierry Cardinal,Guy Matzen +6 more
TL;DR: It is shown for the first time that fully dense transparent polycrystalline ceramics can be simply obtained by direct and complete crystallization from glass for the previously unreported composition, BaAl 4 O 7.

Tuneable nanostructuring of highly transparent zinc gallogermanate glasses and glass-ceramics
Sébastien Chenu,Emmanuel Véron,Cécile Genevois,Guy Matzen,Thierry Cardinal,Auriane Etienne,Dominique Massiot,Mathieu Allix +7 more
TL;DR: In this article, a new nanostructured gallogermanate-based glass materials exhibiting high transparency in the visible and infrared regions are fabricated by conventional melt-quenching.

Long-lasting luminescent ZnGa2O4:Cr3+ transparent glass-ceramics
TL;DR: In this paper, a simple heat treatment of a 55SiO2−5Na2O−17ZnO−23Ga2O3 parent glass composition is proposed to explain the crystallization process occurring in a spinodal phase separated glass.

Therapy modifies cystine kidney stones at the macroscopic scale. Do such alterations exist at the mesoscopic and nanometre scale
TL;DR: Powder neutron diffraction analysis and/or scanning electron microscopy examination of cystine stones provide evidence that usual alkalinization by sodium bicarbonate associated with high diuresis significantly reduces the size of both nanocrystals and crystallites, while for other treatments, including alkalinizing drugs and thiol derivatives, the data suggest mainly changes in the topology of crystallites.
First transparent oxide ion conducting ceramics synthesized by full crystallization from glass
Marina Boyer,Xiaoyan Yang,Alberto José Fernández Carrión,Quanchao Wang,Emmanuel Véron,Cécile Genevois,Louis Hennet,Guy Matzen,Emmanuelle Suard,Dominique Thiaudière,Celia Castro,Denis Pelloquin,Ling Bing Kong,Xiaojun Kuang,Mathieu Allix +14 more
TL;DR: In this article, the authors used full crystallization from glass as an innovative process to elaborate completely dense transparent oxide conductors, such as Ln1+xSr1−xGa3O7+δ (Ln = Eu, Gd or Tb) ceramics with bulk conductivity greater than 0.02 S cm−1 at 500 °C.
