Wall friction and Janssen effect in the solidification of suspensions
Brice Saint-Michel, Marc Georgelin, Sylvain Deville +1
We address the mechanical effect of rigid boundaries on freezing suspensions. For this we perform the directional solidification of monodispersed suspensions in thin samples and we…
Sedimentation of self-propelled Janus colloids: polarization and pressure
Felix Ginot, Alexandre Solon, Yariv Kafri +3
We study experimentally-using Janus colloids-and theoretically-using Active Brownian Particles- the sedimentation of dilute active colloids. We first confirm the existence of an ex…
Influence of particle size on ice nucleation and growth during the freeze-casting process
Sylvain Deville, Eric Maire, Audrey Lasalle +4
The solidification behaviour of suspensions of alumina particles during directional solidification is investigated here by in situ observations using X-ray radiography and tomograp…
Metastable and Unstable Cellular Solidification of Colloidal Suspensions
Sylvain Deville, Eric Maire, Guillaume Bernard-Granger +5
Colloidal particles are often seen as big atoms that can be directly observed in real space. They are therefore playing an increasingly important role as model systems to study pro…
Freezing-induced ordering of block copolymer micelles
Jérémy Dhainaut, Giulia Piana, Sylvain Deville +2
We demonstrate here the ordering of block copolymer micelles by ice templating, below 0 °C. We used this for the preparation of silica monoliths that present an ice-templated macro…
Freezing-induced self-assembly of amphiphilic molecules
P. A. Albouy, S. Deville, A. Fulkar +6
The self-assembly of amphiphilic molecules usually takes place in a liquid phase, near room temperature. Here, using small angle X-ray scattering (SAXS) experiments performed in re…
