postdoc kirigami sheets in flows (LadHyx)

Dear colleagues,
I am currently looking for a 2-year postdoc to work on the ANR-funded project FLORIGAMI. This project lies at the interface of two exciting domains that are fluid/structure interaction and mechanical metamaterials. The work concerns the experimental and theoretical study of the behavior of kirigami sheets in flows.

Potential candidates should contact me by email. For further details and information on how to apply, see the attachement.
I would be grateful if you could forward this announcement to any potential candidate.

Thank you very much,
Best regards,

Sophie Ramananarivo, Ladhyx, Polytechnique

Dear colleagues,

Please find attached an offer for a temporary teaching assistant (ATER) position in soft matter physics at ESPCI in Paris.
The teaching part includes 135 hours of tutorial classes and practical works in statistical physics
and soft matter physics (phase transitions, soft interfaces) for the ESPCI students.
The research part will be held at SIMM-UMR7615 lab and deal with interfaces, mechanics and cavitation.

Best regards,

post doc Shear thickening Pipe Flow (IUSTI-Marseille)

Adding a sufficient quantity of small repulsive particles (e.g. cornstarch, CaCO3 + additives) to a Newtonian liquid triggers spectacular behaviors: the suspension flows under low shear stresses and jams, i.e. solidifies, at larger stresses. Recently, this sharp transition has been shown to result from the sudden establishment of frictional contacts between the particles as the repulsive stress is overcome1,2, and to trigger a new type of waves (‘Oobleck’ waves)3. However, its consequences on such a simple and ubiquitous flow as the flow in a straight pipe is still an open question.

The post-doc will precisely tackle this, apparently, simple question: How does a shear-thickening suspension flow inside a pipe? Using experiments with model shear-thickening suspensions, the goal is to address how the resistance and structure of the flow depend on the level of stress and pipe dimensions. The sliding of the particles at the wall and their migration across the pipe will be considered. In the footprints of Reynolds4, addressing the transition to the shear-jamming of the suspension will also demand to probe the stability of the flow – both in terms of steadiness and laminarity.

This research will be performed in partnership with Chryso, a company developing additives (super- plasticisers) for high performance, high-flowability concretes. The results, first obtained with model shear thickening suspensions, will then be compared to the behavior of calcium carbonate + superplasticizers suspensions, with the aim to improve fluidizing additive characteristics and concrete pumping conditions.

Context: The work will be mostly experimental involving advanced pressure-imposed rheological charac- terizations, pressure measurements and X-Ray imaging technics. It will be performed at IUSTI under the supervision of H. Lhuissier, P. Boustingorry, B. Metzger and Y. Forterre. This PostDoc is part of the ANR project ScienceFriction which also comprises theoretical and numerical approaches in collaboration with M. Wyart at EPFL, Switzerland, and with R. Mari at LiPhy, Grenoble. One other post-doc and two other PhDs will simultaneously work on other aspects of the project. We thus expect synergetic interactions and constructive collaborations between the partners and the students of this project.

Candidates having a background in Physics, Fluid Mechanics, Soft Matter, Physical chemistry and with a strong taste for both experiments and theoretical analysis are invited to apply (CV+Letter of support).
