Experimental study of model plastic micro-particles motion in urban hydrosystems
In the context of urban micro-plastic wastes management in sewer networks and combined storms overflows, this PhD project studies plastic micro-particles dynamics in flows typical of urban hydrosystems. In this study, model particles will be manufactured with varying properties (shape, size, density…) and placed in open channel flows in order to study their dynamic (transport, entrapment…) in different flow configurations.

The objective of the thesis is to develop multifunctional metal-organic molecular materials with magnetic and transport properties (electrical conductivity). The thesis project involves the synthesis of ligands of borazine type substituted by nitroxide radicals to be complexed with magnetic metal ions (3-5d or 4f). We expect these architectures to have ferri- or ferromagnetic and conduction properties by delocalization of the radical electrons on the borazine core. The compounds will be structurally characterized by X-ray diffraction and their magnetic and electrical properties will be studied with a focus on understanding the relationships with the structure of these systems.


Morgane Zimmer - INL/IMP


The objective of the thesis is to develop new eco-responsible processes adapted to industrial production for the fabrication of microfluidic systems allowing the study of spheroids. The first phase of the project involves the use of biopolymers, such as chitosan, functionalized or not, in association with other biopolymers or natural molecules, to form microstructured and sealed structures. The second phase of the project consists of providing permanent magnetisation properties to these structures by incorporating magnetic nanoparticles organised under a magnetic field. Finally, the last phase of the project will be the realisation of a microfluidic system comprising a magnetic channel allowing the selective separation of cells, and a perfused micro-culture chamber allowing the study of spheroids in a controlled environment.

Mathias Desseaux - LMI/ILM

The objective of the thesis is to propose new experimental investigations and thermodynamic modelling for the phase equilibrium diagrams of different Magnesium - Transition Metal (Mg-X; X = Fe, Mn ...) binary systems.
First, the thesis will focus on the High Temperature (HT) study of these binary systems. In particular, the Liq-Liq miscibility gaps, which have been little studied experimentally until now.
Then, a study under High Pressure (HP) will be carried out in collaboration with the ILM through the use of the experimental park proposed by the PLECE.
Finally, the acquired experimental data will be used for a thermodynamic modelling (CALPHAD) with pressure and temperature variables.

Arne Bahr - LPENSL/LCENSL

Magnetic resonance spectroscopy can be used to detect and identify paramagnetic species and usually relies on detecting the absorption or emission of microwaves by their spins. As these spins are weakly coupled to the microwave field, its use is restricted to sufficiently concentrated samples. Using quantum circuits techniques developed in the Quantum Circuits group of the Laboratoire de Physique à l’ENS de Lyon, the detection sensitivity can be considerably improved. This allows to measure samples available only in small volumes, such as the diamagnetic molecular probes conceived by the group Chimie-BioOrganique of Laboratoire de Chimie à l’ENS de Lyon, which might lead to precious new insights in their structures and internal processes.

Pauline Bregigeon - AMPERE/ILM

The subject of the thesis consists in developing a solution enabling culture and monitoring of spheroids of controlled size and shape, easy introduction of fresh medium and reagents and subsequent electroporation inside a unique device. This involves the study of fluid transport within microstructured hydrogels and of the effects of pulsed electric fields on spheroids. These effects will be characterized by impedance spectroscopy and by confocal microscopy and the results will guide the design and fabrication of an integrated bioreactor using 3D plastronics. This device will enable the manipulation of hundreds of spheroids in parallel, thereby providing a unique tool for evaluating in vitro the efficacy of treatments based on electroporation, such as electrochemotherapy or electro-gene therapy.

Louis Combe - ILM/MATEIS

We are experimentally studying the slow shear of a compressed granular medium, where energy continually accumulates in the structure of the medium and is released by sudden and intermittent reorganizations, called avalanches. A combined approach of fracture mechanics, statistical physics and artificial intelligence will allow a better understanding of the dynamics of catastrophic avalanches.

Thermochemical energy storage in hygroscopic salts - ceramics architectured composites
Thermochemical energy storage is a promising technique for storing intermittent thermal energy (of solar origin for example). It is based on the hydration and dehydration of hygroscopic salts. However, during the cycles of use, the efficiency of the storage devices decreases, in particular because of an uncontrolled agglomeration of the salts.
This thesis project aims to propose porous ceramic matrices, able to trap very large quantities of salts while avoiding their aggolmeration, and therefore to increase the efficiency and lifespan of thermochemical energy storage systems.

Laura Vanessa Reyes Villamizar - LGPC/IRCELYON

In the framework of Biorefinery and the long-term production of raw materials from renewable resources, this project aims to design and implement a reactive distillation process for the recovery of carboxylic acids from black liquor. For this purpose, solid acid catalysts based on mixed oxides materials will be prepared, characterized and implemented in stirred tank reactors and in a lab-scale distillation column.
