Second annual meeting of the GDR SoPhy

Second annual meeting of the GDR SoPhy

The meeting will take place at the Centre Paul Langevin in Aussois from May 21st (Tuesday) to May 24th (Friday).

This year, two invited speakers will discuss their research field, and two invited lecturers will deliver 1h30 introductory lectures on shaping routes for porous materials and synchrotron X-ray micro- and nano-analysis.

Invited speakers:

  • Wiebke Drenckhan, Institut Charles Sadron et CNRS Univ. Strasbourg: “Elucidating the effect of fluorocarbons in reducing the pore size of polyurethane foams”
  • Marie Albéric, Laboratoire de Chimie de la Matière Condensée de Paris: “From amorphous calcium carbonate precursors to mineralized biological materials: the case study of sea urchin biominerals”

Invited lecturers:

  • Cédric Boissière, Laboratoire de Chimie de la Matière Condensée de Paris: “Shaping porous materials”
  • Julie Villanova, ESRF: “Synchrotron X-ray micro- and nano-analysis”

Rhéologie pour la fabrication additive de matériaux durs

Rhéologie pour la fabrication additive de matériaux durs

Date: 28-29 mars 2024, Campus de la DOUA, Villeurbanne

RHEO-FAB est un atelier scientifique qui traite de la rhéologie appliquée à la fabrication additive de matériaux durs. Il est porté par le laboratoire MATEIS de l’INSA-Lyon et le groupe de recherche SoPhy. Il a pour ambition de créer des passerelles entre la rhéologie fondamentale des suspensions colloïdales et des pâtes d’une part, et les techniques d’impression 3D de matériaux durs d’autre part.

L’événement consiste en un colloque de deux jours comprenant

  • des ‘oraux invités’ sous forme de cours et,
  • deux sessions de conférences ouvertes où les participants auront l’occasion de présenter leur travaux originaux.

Liquid to solid foam workshop

Liquid to solid foam workshop

The workshop will take place in Paris (MSC lab) on Monday 18th of December 2023.

Foams are made of liquid or solid containing gas bubbles. Liquid foams comprise many liquid-gas interfaces, so their structure and dynamics are ruled by liquid surface tension. Solid foams are porous materials used for properties like their lightness, their low thermal conductivity or their permeability. Solid foams are generally elaborated from liquid foams that solidify, and the intermediate solidifying foams have specific properties —structure, ageing, mechanical and rheological properties, etc.- ruled both by surface tension and bulk elasticity.

The objective of this workshop is to better understand them and therefore to gather scientists from both liquid and solid foam communities.

Registration is open until November 17th 2023.

Invited speakers

  • Samuel Forest (Centre des Matériaux, CNRS - Mines Paris PSL): “Mechanical properties of metallic foams”
  • Aurélie Hourlier-Fargette(Institut Charles Sadron, CNRS - Université de Strasbourg): “Foams and intruders: from liquid systems to polymeric architected materials”
  • Olivier Pitois (laboratoire Navier, Université Gustave Eiffel - CNRS - Ecole des Ponts): “From model foam to materials”

First annual meeting of the GDR SoPhy

First annual meeting of the GDR SoPhy

The very first annual meeting of the GDR SoPhy will take place at ENS de Lyon from June 5th (Monday) to June 7th (Wednesday).

Among the topics relevant to the GDR SoPhy, we will address the following ones:

  • Synthesis and characterization of elementary building blocks for the synthesis of soft solids serving as precursors
  • Control of the organization processes of the elementary building blocks and/or self-assembly
  • Use of external fields to texture soft solids - memory effects
  • Transformation of a soft solid into a hard material: analysis of the properties inherited from the soft precursor

Invited speakers:

  • Annie Colin, ESPCI: “Fluidification de suspensions non-browniennes: rôle de la formulation et rôle des ultrasons”
  • Laurence Rozes, LCMCP: “Design or organic-inorganic networks from nano building units: the “hybrid” effect on dynamic properties of polymers”
  • Franck Artzner, Institut de Physique de Rennes: “Control of the Hierarchical organization processes between complementary building blocks by irreversible Self-Assembly: a few examples of local and macroscopic rules”
  • Damien Montarnal, CP2M: “Sol-gel synthesis of vitrimers with high glass transition temperatures”
  • Sophie Senani, SAFRAN Tech: “From Soft matter to hard materials: Applications and Stakes of this transformation for Aeronautical Materials”
