- Les Journées de la Diffusion Neutronique (JdN), organisées par la SFN, auront lieu à Biarritz du 14 au 17 novembre 2022. Cette édition particulière des JDNs est organisée avec la participation de la Société Espagnole de Diffusion Neutronique.
En parallèle des sessions, la SFN et la 2FDN vous proposent une journée d’exposés et de réflexion sur la diffraction en temps de vol, pour commencer à préparer la future génération d’utilisateurs de l’ESS.
Inscriptions jusqu’au 15 octobre ! Plus d’informations sur : https://jdn-conference.net/index.htm

Edge-On (Cellulose II) and Face-On (Cellulose I) Adsorption of Cellulose Nanocrystals at the Oil–Water Interface: A Combined Entropic and Enthalpic Process.
Nanocelluloses can be used to stabilize oil–water surfaces, forming so-called Pickering emulsions. In this work, we probed the organization of native and mercerized cellulose nanocrystals (CNC-I and CNC-II) adsorbed on the surface of hexadecane droplets dispersed in water by coupling small-angle neutron scattering with contrast variation experiments and molecular dynamics simulations. We showed that there exists a preferred interacting crystalline plane for both allomorphs that exposes the CH groups (100 and 010) and is therefore considered hydrophobic. This study suggests that whatever the allomorph, the migration of CNCs to the interface is spontaneous and irreversible, leading to highly stable emulsions.
