L’AGENDA CHIMIE PARISTECH - PSL

NMR over orders of magnitude of magnetic field... in each experiment Prof. Dr. Fabien Ferrage, Laboratoire des biomolecules (CNRS/SU/ENS) Department of Chemistry, Ecole Normale Supérieure, PSL University Where: Préfabriqué 1 de Chimie ParisTech - PSL Abstract: High-resolution, high-field NMR is a powerful tool to investigate matter, with broad applications in chemistry, material science, structural biology…

Physico-chemical characterization of complex colloidal systems Lingsam Tea, Forschungszentrum Juelich Where : Amphi Holweck A colloid consist of a dispersion of small objects (from few nanometers to few micrometers) in a continuous phase. This broad definition include emulsions, suspension,  foams, or gels. These systems are widely used in everyday life, for example mayonnaise, tooth paste,…

DNA DRIVE: a new technology for sustainable data storage Stéphane Lemaire, Sorbonne Université & Biomemory   The storage of digital data is a major challenge in our modern societies. Current digital media stored in data centers are fragile, bulky and energy-intensive. The ongoing digital transformation of our societies requires a major disruption of our digital…

Rheology and stress-induced dynamics of vitrimers Fardin Khabaz, Université d'Akron Where : Amphithéâtre Holweck Vitrimers are a class of polymers that bring together desirable mechanical properties of thermosets with the reprocessing of thermoplastics. This ability arises from the rearrangement of the vitrimer network via a bond shuffling mechanism while its cross-link density remains preserved. As…

Statistical mechanics of large scales in turbulent flows Stephan Fauve, ENS In many turbulent flows, scales larger than the forcing scale display equipartition of energy. This familiar result of equilibrium statistical physics could look surprising in turbulent flows which are considered as a canonical example of an out of equilibrium dissipative system. After displaying several…

Writing in Water Thomas Palberg, Johannes-Gutenberg Universität   Writing is an ancient cultural technique, typically performed by leaving some trace in or on a solid surface. We here explore the possibilities of leaving well formed letters in a liquid medium. We employ micron sized particles suspended in water as ink and ion exchange resin beads…

25ème Journée de Chimie Organique et Chimie Organique Biologique de la Montagne-Ste-Geneviève Où : Institut Curie (12 rue Lhomond, 75005 Paris, Amphithéâtre Constant Burg) Quand : le 31 mai 2022 Cette journée scientifique destinée aux jeunes chercheurs a pour but de leur permettre d’exposer leurs travaux de recherche et d’échanger en confrontant leurs résultats à…

Les dérivés d’hydroxylamines en tant que précurseurs de nitrènes de fer : fonctionnalisations d’alcènes et développement récents   Guillaume Prestat, Université de Paris Cité   Où : Salle Ondes   A l’instar des carbènes, les nitrènes sont des intermédiaires réactionnels hautement réactifs. Le développement des métallo-nitrènes a permis de contrôler cette réactivité pour en faire…
