Actualités
La SFN et la 2FDN vous souhaitent le meilleur pour cette nouvelle année 2025 ! Avec autant de neutrons que de besoin pour développer de nouveaux outils et des recherches porteuses de résultats originaux…
- La SFN organise comme chaque année les Journées de la Diffusion Neutronique (JDN). Les JDN 2025 se dérouleront au village de vacances « Les Balcons du lac d’Annecy » à Sévrier, en Haute-Savoie, du 2 au 5 juin 2025. Réservez les dates !
Les journées seront organisées autour de 5 sessions thématiques : matière molle, matière condensée, magnétisme, biologie & environnement et Instrumentation. Une session thématique sera organisée sur les synergies entre grandes infrastructures de recherche. - La conférence ICNS (International Conference on Neutron Scattering) aura lieu à Copenhague du 6 au 10 juillet 2025. La date limite pour la soumission des résumés est fixée au 15 janvier.
- Prix de thèse SFN. Ce prix, d’un montant de 1500 euros, récompense un travail de thèse de qualité pour lequel l’apport de la diffusion neutronique est déterminant. L’attribution du prix de thèse est accompagnée d’une invitation à présenter son travail de thèse lors des prochaines JDN.
La date limite de candidature est fixée au 31 janvier 2024.
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
Measuring the bending rigidity of microbial glucolipid (biosurfactant) bioamphiphile self-assembled structures by neutron spin-echo (NSE)
Neutron spin echo (NSE) is used in this work to measure the bending rigidity, k, of self-assembled nanostructures prepared with new glycosylated lipids of biological origin, a class of molecules better known for their surface active properties than for their membrane-forming properties. NSE was chosen as essentially being the only technique allowing to measure k on nanoscale objects of three different shapes, vesicles, membranes, fibers. The use of neutrons is here critical for the structure which is probed by scattering while the dynamics, from which k is derived, is probed by the magnetic interaction between neutrons (spin-1/2) and matter.
