New insights into phosphate based materials for the immobilisation of actinides
Stefan Neumeier,Yulia Arinicheva,Yaqi Ji,Julia M. Heuser,Julia M. Heuser,Piotr M. Kowalski,Philip Kegler,Hartmut Schlenz,Dirk Bosbach,Guido Deissmann +9 more
TL;DR: In this paper, a perspective on the recent advancements in the understanding of phosphate-based ceramics and their properties with respect to their application as nuclear waste forms is provided, highlighting the benefits gained from synergies of state-of-the-art experimental approaches and advanced atomistic modeling tools for addressing properties and stability of f-element-bearing phosphate materials.
Journal ArticleDOI
Why natural monazite never becomes amorphous: Experimental evidence for alpha self-healing
Anne-Magalali Seydoux-Guillaume,Xavier Deschanels,Cedric Baumier,Stefan Neumeier,Willlliamam John Weber,Willlliamam John Weber,Sylvain Peuget +6 more
TL;DR: In this paper, the existence of the α-healing mechanism was demonstrated experimentally for the first time in monazite, acting in this structure due to electronic energy loss of α particles.
Journal ArticleDOI
Zeolite based trace humidity sensor for high temperature applications in hydrogen atmosphere
TL;DR: In this paper, the authors presented a humidity sensor based on H-ZSM-5 type zeolite that is suitable to detect traces of humidity (∼10-110ppmV) under harsh conditions, e.g. reducing atmosphere (H2) and high temperature (up to 600°C).
Journal ArticleDOI
Thermochemistry of La1−xLnxPO4-monazites (Ln = Gd, Eu)
Stefan Neumeier,Philip Kegler,Yulia Arinicheva,Anna Shelyug,Piotr M. Kowalski,Christian Schreinemachers,Alexandra Navrotsky,Dirk Bosbach +7 more
TL;DR: Enthalpy of formation (ΔH°f) of single phase orthophosphate solid solutions La 1−xLnxPO4 (Ln = Eu, Gd; 0).
Journal ArticleDOI
Determination of the Solubility of Rhabdophanes LnPO4·0.667H2O (Ln = La to Dy)
Clémence Gausse,Stéphanie Szenknect,Dan Wen Qin,Dan Wen Qin,Adel Mesbah,Nicolas Clavier,Stefan Neumeier,Dirk Bosbach,Nicolas Dacheux +8 more
TL;DR: In this article, a systematic study of the solubility of the rhabdophanes LnPO4·0.667H2O (Ln = La-Dy) was performed through oversaturation and undersaturation experiments at different temperatures (298-363 K) to demonstrate the reversibility of the equilibria.
