These materials are available in large quantities and with a large diversity considering dimensions – cell diameters from µm to mm – and nature – metals, ceramics, plastic,.. . Solid open-cell foams are highly porous (from 60 to 97 %) monolithic media with a continuous cross-linked strut network resulting in a quite irregular structure. These structures enable a considerable reduction of pressure drop combined to very high geometrical specific surface areas. Fluid flow can proceed in all the directions resulting in a good radial mixing.

Indeed, performances in odor perception of the animal kingdom outperform artificial sensors derived from micro and nano-technologies by several orders of magnitude (electronic noses, NEMS/MEMS sensors, MOX sensors). This Ph.D. position, right at the interface between biology and microtechnology aims at understanding and re-creating some of the functions observed
in mammals for capture of odors molecules in small amount, with a focus the “integrated systems” that constitutes living organisms. Indeed the work will not be centered on technological development but will rather focus on a “co-evolution” of the different system’s components. The Ph.D. student will share his time between LETI/Carnot Institute in Grenoble for the microfluidic and sensors part and Tours University/CNRS for the biological part and flux imaging experiments.

Applications are invited for the above post to work on the project “NECtAR: Nanofluidic Energy Conversion using reActive suRfaces”, funded by the French National Research Agency (ANR). Water desalination and sustainable energy harvesting are among the greatest challenges of our society, and nanofluidics offers promising solutions to address them. Nanofluidic energy conversion systems rely on electrokinetic (EK) effects, which couple different types of transport (hydrodynamic, electric, ionic, thermal…) at interfaces. EK effects are sensitive to the molecular detail of interfaces, and should thus depend on their physical chemistry. Yet the possibility to couple surface reactivity and EK transport to enhance the performance of nanofluidic devices has never been studied to the best of our knowledge.

Currently we investigate the mechanics of plant growth and the fluid dynamics enabling the slime mold Physarum polycephalum to adapt its network-like body to its environment. Our approach is primarily theoretical and closely interacting with experiments. On the theoretical side, we use analytical and numerical methods from mechanics, fluid dynamics, statistical physics and non-linear dynamics. On the experimental side, we have our own laboratory where we investigate the adaptation dynamics of Physarum polycephalum and enjoy collaborations around the world.
