It happened at LIPhy

The 2022 thesis prize of the French Group of Rheology has been awarded to Nicolas Cuny for his thesis entitled "Derivation of constitutive models: from the microstructure to the rheology of soft dense suspensions" carried out at LIPhy and supervised by Romain Mari and Eric Bertin.

Rare events are by definition difficult to observe, and their numerical study is all the more complex. A class of methods, "population dynamics algorithms" allowed progress in this area.

The first GDR IDE Days "Interaction Disorder Elasticity" will be held on the UGA campus.

Parabolic flights for the study of blood microcirculation.

Researcher of the PSM team at LIphy, professor at the University of Grenoble Alpes. See you on November 22 for the awarding of his prize.

Drought is a threat for plants, as it induces gaseous embolisms which can block the circulation of sap in their veins. Recent images at the scale of single leaves have revealed that such embolisms do not invade the vein network smoothly, but rather by intermittent puffs.

Water bubbles have a very sharp acoustic resonance frequency, as evidenced by the sound of bubbling produced in a glass when blowing through a straw. But does this resonance depend on the shape of the bubbles? Although bubbles are most often spherical, they can also be toroidal, like those produced by dolphins in their water games, which are the equivalent of our smoke rings.

L'école d'été Active Matter and Complex Media aura lieu à l'Institut d'études scientifiques de Cargèse (Corse).

Elisabeth Charlaix, CNRS Silver Medal 2009, Professor at the University of Grenoble Alpes, conducting research at the Interdisciplinary Laboratory of Physics (LIPhy, CNRS/UGA), is the winner of the prestigious "Fluid dynamics prize recipient" of the American physical society (APS) which rewards outstanding achievements in the field of fluid dynamics research.

Blue energy from the difference in salinity between fresh river water and salt ocean water is an avenue to explore for the energy transition thanks to the contributions of fundamental research on nanomaterials.

The migration of cells in 3D media is a complex process and plays a key role in the development of cancers. During metastasis, cancer cells develop a strategy and a mode of migration adapted to their environment to invade other tissues. In this study, we analyzed the migration of cancer cells with different metastatic potentials in various collagen matrices.

Researchers have devised an optical architecture to calculate the correlation of radio signals in an analog way. This operation would make it possible to locate radio transmitters with precision, or to improve the performance of optical interferometry in astronomy.

Congratulations to Guillaume Godefroy, winner of the 2022 Thesis Prize in radioscience. His thesis: "New approaches for photoacoustic imaging of blood vessels: quantitative 3D imaging of fluctuations and reconstruction assisted by deep learning", defended on October 12, 2021.

Fluorescence Fluctuation Spectroscopy (FFS) is a widespread technique used to evaluate densities or concentrations of molecules, aggregates or particles in biological environments (cells, solutions, surfaces). In reality, when the species of interest are not uniformly fluorescently labeled, these techniques do not give quantitative results.

The laboratory's mechanics platform has been asked to shape snow corers for the Centre National de Recherches Météorologiques.

Photoactivatable ion channel toxins derived from animal venoms provide the opportunity to control the activity of excitable cells with high spatiotemporal precision.

Dense suspensions of soft particles possess relatively complex rheological properties, such as the existence of a threshold stress to flow. A new statistical physics approach allows to obtain a tensor constitutive model from the dynamics of the soft particles of the suspension, and thus to link the rheology to the anisotropy of the microstructure.
