Missions

We are looking for a motivated candidate for a 6-month contract in the ICGM Polymers Department with 2 stays (2 weeks) in the CBMN laboratory. This contract will allow synthesizing and characterizing of grafted surfactants based on chitosan oligomers. Secondly, these various surfactants will be used to formulate emulsified systems obtained under laminar or turbulent conditions. The stability of the emulsions will be a criterion of choice in the two systems studied. Rheological characterization and accelerated ageing will also be carried out.

Activités

Synthesis of surfactants based on bio-based materials, characterization by NMR, IR, tensiometry and microscopy.... Achievement and rheological characterization of emulsions.

Compétences

Master's level in polymer chemistry with skills in the physical chemistry of polymers. Knowledge of emulsions and their characterization would be good.

Contexte de travail

Through a fruitful collaboration between the Institut Charles Gerhardt Montpellier (ICGM) and AJINOMOTO that began 3 years ago, the project aims to develop new chitosan-based surfactants and to characterize them with the help of a third partner from Bordeaux: the Institute of Chemistry and Biology of Membranes and Nano-objects (CBMN). AJINOMOTO is a multi-national company specialising in the supply of development solutions in various fields of applications such as pharmaceuticals and agrochemicals. In particular, it is developing a range of petroleum-based high-performance surfactants and aims to improve its ecological footprint by developing new bio-based surfactants that can meet the needs of agrochemical formulations.

Le poste se situe dans un secteur relevant de la protection du potentiel scientifique et technique (PPST), et nécessite donc, conformément à la réglementation, que votre arrivée soit autorisée par l'autorité compétente du MESR.
