Lead-vanadate sorbents for iodine trapping and their conversion into an iodoapatite-based conditioning matrix

Autor: R. Pénélope, L. Campayo, M. Fournier, S. Le Gallet, A. Gossard, A. Grandjean

Publikováno v: Frontiers in Chemistry, Vol 10 (2022)

New lead-vanadate based sorbents were synthesized with the aim to entrap and confine gaseous iodine in off-gas streams coming from reprocessing facilities of spent nuclear fuel. Their synthesis relies on the shaping of a lead-vanadate, lead sulfide a

Reactivity of Ni-Al nanocomposites prepared by mechanical activation: a molecular dynamics study

Autor: S. Le Gallet, Florence Baras, Clara Desgranges, Olivier Politano, A. Fourmont

Publikováno v: Journal of Applied Physics
Journal of Applied Physics, American Institute of Physics, 2021, 129 (6), pp.065301. ⟨10.1063/5.0037397⟩

High energy ball milling of metallic powders leads to high reactivity in the milled mixture. The reaction is often faster and starts at a lower temperature. However, the mechanisms responsible for this high reactivity are not yet completely understoo

Spark Plasma Sintering tool design for preparing alumina-based Functionally Graded Materials

Autor: S. Le Gallet, Frédéric Bernard, C. Morin, Mostapha Ariane

Publikováno v: Ceramics International. 42:3056-3063

A way to produce Functionally Graded Materials (FGM) is by means of Spark Plasma Sintering (SPS) and specifically designated tools. These new tools permit a current density modulation and therefore a temperature variation along the z-axis. The key fe
