The person recruited as a post-doctorate will carry out research work within the framework of the PLAS4CHEM project, funded by the ANR. Its activities will concern the development and experimental study of plasma sources in microfluidic processes for chemical synthesis.
The PLAS4CHEM project is based on the development and use of microstructured chemical reactors in order to be able to carry out chemical synthesis reactions without catalyst and without solvent thanks to a precise manipulation of high energy radical species. Microstructured reactors have been attracting interest for several years because of the unprecedented level of control they can bring when conducting chemical reactions and the promise of a rapid scale-up obtained by simple parallelization. The generation of a plasma within microfluidic processes has presented many advantages over the past ten years: the plasma science allows the generation of radicals species, excited neutrals, metastables, photons,… at atmospheric pressure and ambient temperature, and the microfluidics makes it possible to control the transfer of highly reactive chemical medium with a great precision. To succeed in controlling the reactivity of such species and properly carry out selective reactions, the precise control of the radical species formation and the fast extraction of product is an absolute requirement.


The objective will be to study the potential offered by different high voltage sources in order to allow the generation of plasma in microchannels with characteristic dimensions of hundreds of microns, in two-phase gas / liquid mixtures. Several types of high voltage sources, industrial or developed within the laboratory, can be studied: sinusoidal excitation (10 Hz-> 70 kHz), nanosecond pulsed source, etc.
The coupling between the high voltage source and the micro-reactor, in particular in terms of energy deposited within the plasma, will be studied as a function of operating conditions (composition of the gas and of the liquid for example). Experimental studies to assess the temperature of the gas at the center of the plasma will also be carried out.


Experimental knowledge of plasma generation at atmospheric pressure or in liquids is required in order to carry out this study.

Work Context

The work will be carried out at the Laboratory of Process and Materials Sciences (LSPM). In the framework of the PLAS4CHEM project, the LSPM works in collaboration with the Processes Plasmas Microsystems team of the Pierre Gilles de Gennes Institute for microfluidics (https://www.institut-pgg.fr/).
