Near-surface transport of polymer solutions and time-dependent soft hydraulics Le 23 Février 2023 à 10h30 en salle Margaux

Séminaire d’Antoine Aubret (LOMA)
Sur le thème « Light-driven assembly of active colloids ». Le Jeudi 2 Février 2023 en salle Margaux à 9h30. Cells are prototypical examples of Active Matter, converting energy at small scale to organize at large scale. This biological complexity challenges our ability to engineer synthetic analogs. In this talk, I will show how we can carve […]

Séminaire de Benoit SHEID
Séminaire de Benoit Sheid (ULB, Bruxelles) sur le thème « Raydrop: a universal single/double emulsion generator based on a non-embedded co-flow-focusing ». Le mercredi 30 Novembre 2022 à 9h30 en salle Sauternes. We present a non-embedded co-flow-focusing device for single and double-emulsification in microfluidics. Experimental results demonstrate the universality of the device in terms of the variety […]
Séminaire de Etienne Piantanida
Séminaire de Etienne Piantanida (Institut de Science et d’Ingénierie Supramoléculaires UMR7006 Université de Strasbourg, France.) sur le thème « Nanocomposite hydrogel for biomedical applications ». Abstract: Hydrogels are materials that can entrap a high amount of water (up to 98%) and, thanks to their porous structure that allows oxygen and nutrients permeation [1], they are suitable for […]
Multi-functional hydrogel capsules
During this presentation, I will present our work on shaping hydrogels with a core-shell structure. Features of the hydrogel membrane in terms of permeability and mechanical properties or the ability to make composite hydrogels will be reported. Flow of a concentrated dispersion of capsules, where friction between objects can be tuned, will also be reported. […]
Etude de deux écoulements complexes
Au cours de ce séminaire, j’aborderai deux sujets distincts mettant en jeu des écoulements complexes. Premièrement, je discuterai de la dynamique d’évaporation dans le cas de surfaces étendues qui génèrent un écoulement convectif causé par la différence de densité entre la vapeur et l’air ambiant. Deux géométries seront abordées, le film circulaire horizontal et le […]
Imbibition, drying and cavitation in nanoporous media
Many porous media contain fluids confined at the nanoscale, including a variety of natural (rocks, plant vessels) and industrial (concrete, filters) materials. In this presentation, I will discuss the dynamics of a few specific phenomena that occur in materials containing nanopores, including capillary condensation and cavitation, which I have investigated at Cornell University using model […]
Combining microdevices and functional droplets in the immune context
Oil-in-water emulsion droplets are deformable particles, with a surface that can be functionalized by biologically adhesive molecules. Having a fluid interface, these molecules are laterally mobile, making the whole microparticle able to interact with immune cells and respond to receptor sollicitations. In this talk, I will present how using emulsion droplets in this context, in […]
Ultramicroélectrodes et microfluidique : Vers de nouvelles perspectives en électrochimie analytique
Les progrès en techniques de microfabrication permettent désormais d’implémenter facilement des électrodes à l’intérieur de microdispositifs pour l’exploitation de nouveaux champs d’application en électrochimie analytique. La réduction des dimensions d’électrodes alliée à un confinement des processus permet en effet d’augmenter les performances en électrochimie mais aussi d’envisager des concepts innovants dans le cadre du développement […]
Carbohydrate-based block copolymer self-assemblies : nanoparticles and sub 10 nm highly nanostructured thin films
Current knowledge in macromolecular engineering allows for the preparation of a myriad of tailored block copolymer morphologies, which play distinguished, multifaceted roles in nanoscience and technology. Such systems exhibit a remarkable ability to self-assemble into a great variety of supra-macromolecular structures both in solution (nanoparticles) and in thin films, whose domain spacing span from few […]
