postdoc UNIfied multi-scale framework for PLASticity of metals, amorphous and cellular materials

voir l’annonce en pdf

Supervisors : Marc Durand, MSC, Université Paris Diderot ( Oguz Umut Salman, LSPM, Université Paris 13 (

A fundamental question in materials science is identifying the microscopic origin of plasticity. Why do materials display plastic rather than elastic response and can we predict when this will occur ? An improved understanding of plastic deformation is important in a wide range of amorphous materials, such as metallic and polymeric glasses, foams, granular materials, colloids, and emulsions.
In molecular materials with crystalline order, plastic behavior is understood in terms of defect nucleation and dynamics. For amorphous materials, a description in terms of topological defects is not possible due to the inherent structural disorder. Therefore identifying and characterizing local plastic events in amorphous materials is essential for a complete understanding of their structural and mechanical properties. Experimentally, the challenge is identifying systems for which the microscopic events are directly observable. This is one of the main advantages of mesoscopic systems, such as foams, and the reason for the interest in making connections between mesoscopic systems and molecular materials.
Foams are interesting as a model for atomic or molecular systems with tunable structural disorder (either quenched of evolving on large time scales) and interactions between units (from pairwise to many- body interactions). Foams are also a model for other soft cellular materials such as emulsions or confluent biological tissues: these systems are constituted of highly deformable (yet almost incompressible) units (bubbles, drops, cells,. . . ). Interfacial energy is the key ingredient in the cohesion and the rigidity of such systems, often constituted solely of fluids.
The proposal aims to bring a unified approach in the understanding of plastic behavior, for both molecular and cellular materials, with various degrees of disorder (from crystalline to amorphous). We will use in conjunction complementary numerical and theoretical models to study the plasticity of two-dimensional foams and compare it with the plasticity of atomic solids, either crystalline or amorphous.
The recruited post-doc will benefit from a world-class interdisciplinary environment, both within the MSC and LSPM labs which developed expertise in numerical and theoretical modelling of heterogeneous media.
We seek motivated researchers, with theoretical and computational expertise. Candidates should have a background in computer simulation, statistical mechanics, or condensed matter. Postdoctoral position is for a period of one year, with estimated starting date January 2019.
Interested candidates can apply by sending their CV (including publication list) and a short research statement (with plans and motivations) by email to with subject: « Application UNIPLAS ».

Environmental fluid dynamics: confronting grand challenges (Les Houches, Jan 2019)

Dear Colleagues,

We would like to announce the international conference,
Environmental fluid dynamics: confronting grand challenges
that will be held in Les Houches, France from 20-25 January 2019.

** Please distribute widely **

Environmental fluid dynamics underlies a wealth of natural, industrial and,
by extension, societal challenges. In the coming decade, as we strive towards
a more sustainable planet, there are a wide range of ‘grand challenge’ problems
that need to be tackled, ranging from fundamental advances in understanding
and modeling of stratified turbulence and consequent mixing, to applied studies
of pollution transport in the ocean, atmosphere and urban environments.
The objective of the event is to gather leading figures in the field of environmental
fluid dynamics to produce a road map for the scientific community. The meeting
will balance the participation of senior and junior faculty, postdocs and graduate
students, to generate an environment that fosters research ideas and directions.

The list of topics covered at the conference is Stratified flow, Multiphase flow,
Ocean transport, Atmospheric and Urban transport and Predictability.
The list of invited speakers is:

Matthew Alford (San Diego, USA)
Peter Bauer (ECMWF, UK)

Postdoc : reactive fluid dynamics (ULB)

Annonce en pdf

Postdoc fellowship in reactive fluid dynamics

Within the MaSNEC project, the Nonlinear Physical Chemistry Unit (NLPC) of the Université libre de Bruxelles (ULB) invites applications for one Postdoc fellowship to begin in October 2018 or soon after.
MaSNEC (Material Synthesis in Non-Equilibrium Conditions) is a project funded by the European Union (EU) through the M-ERA.NET network. This network has been established to support and increase the coordination of European research and innovation programmes and related funding in materials science and engineering. This project involving 4 european partners is coordinated by NLPC.
General research performed at NLPC focuses on the experimental and theoretical study of spatio-temporal patterns and dynamics emerging from the coupling between chemical reactions and hydrodynamic flows. The research to be developed at NLPC in the context of the MaSNEC project aims to grow innovative materials and control their properties via synthesis in non-equilibrium reactive conditions maintained through convective flows due to injection of one reactant into the other. New experimental protocols are currently developed to take advantage of imposed out-of-equilibrium constraints to synthesize and control the growth of structured surfaces, composite coatings and multilayered tubes.
In this framework, we seek to hire a postdoc who will perform theoretical analyses in the context of flow-driven precipitation in porous media. The successful candidate will develop models based on continuum mechanics (fluid/solid mechanics, reaction-diffusion-convection dynamics) to rationalize experiments where the interplay between solid precipitate and hydrodynamic flows play a central role. He/She will develop models to understand how hydrodynamic flows affect precipitation reactions at the macroscale and to investigate how the amount and spatio-temporal distribution of precipitate depends on the experimental conditions.
Type of appointment

15 months full time. The successful candidate must have appropriate authorization to work in the EU before employment begins.

Approximately 2 400€ net per month.
Required Qualifications

PhD in Chemistry, Physics or related fields. Good oral and written communication skills (in English) to work in a multidisciplinary team environment. Good knowledge of reaction-diffusion(-convection) dynamics. Good knowledge of continuum mechanics (both fluid and solid).
Preferred Qualifications

Good programming skills to develop numerical codes complementing the theoretical analysis and to post-process and analyze experimental data through image analysis. Ability to write scientific publications and deliver scientific presentations in English.
