Actualités
Le workshop « Neutrons and Quantum Matter » qui s’est tenu le 21 novembre à Grenoble a réuni 70 participants provenant d’une dizaine de laboratoires français avec une forte représentation du Laboratoire Léon Brillouin, de l’IRIG, de l’Institut Néel et de l’Institut Laue Langevin. Le financement a été assuré par la 2FDN et la fédération de recherche Quantalps.
Les exposés invités étaient répartis sur trois thèmes : les concepts émergents, la supraconductivité et le magnétisme. Une session poster portée par les étudiants en thèse et les post-doctorants a complété ce programme. La forte participation montre le dynamisme de la communauté et les longues plages de temps réservées aux discussions (pauses, repas, session posters) ont permis des échanges fructueux. Les participants ont salué cet évènement de façon très positive.
Prochaines dates limites :
- ILL appel à propositions : 17 fév. 2025.
- 2FDN appel à propositions : 1 mars 2025.
- ISIS appel à propositions : 3 mars 2025.
Actualité scientifique du mois
Insertion de nanoparticules anisotropes dans des phases lamellaires tensioactives
Isabelle Grillo (1973-2019) était responsable de l’instrument de DNPA D33 à l’ILL, et appréciée de la communauté des neutrons. Elle était particulièrement connue pour déceler les phénomènes physiques fondamentaux à l’œuvre dans des systèmes d’apparence ordinaire, comme la stabilité du Pastis. Elle a publié environ 225 articles, dont 3 articles sur le sujet de sa thèse de doctorat dédiée à l’étude des mécanismes d’insertion d’argiles dans des phases lamellaires, une problématique importante dans le monde industriel, mais une vue d’ensemble finale manquait encore. Un quart de siècle plus tard, l’article présenté ici vise à combler cette lacune et à faire connaître des résultats issus de sa thèse qui restent d’actualité.
