Opening of two PhD positions

All-cellulose composites and phase-change materials for insulation

(CELLPHI)

The CELLPHI project aims at developing all-cellulose composites comprising phase change materials for insulation purposes. These materials will be biobased and biodegradable. Their aim is to harvest low grade thermal energy, which enables real energy economies when used for building insulation. The CELLPHI project will be carried out in two laboratories (LCS and LOMC), each laboratory bringing its own expertise.

The first laboratory (LOMC, Le Havre Normandy University) will focus on the manufacturing of cellulosic materials called all-cellulose composites, in which a phase change material will be added. The composites will ultimately be manufactured in the form of filaments by the wet-spinning method, similarly to the mass-produced viscose fibers. The microstructure of the dope, gel and of the final dry materials will be analyzed by X-ray diffraction, small-angle X-ray scattering (SAXS), Atomic Force Microscopy in immersion, and polarized optical microscopy under thermally regulated environments.

The second laboratory taking part in this project is the LCS (Caen Normandy University/ENSICAEN) and the work conducted there will be centered around the use of advanced spectroscopy techniques and thermal analysis. Machine learning will be used to assess the relationships between structure, properties and processing. Diffusion RMN will be used to assess the diffusive aspects of the phase-change material in the cellulosic matrix early on in the process, when it is still in the semi-dilute or anisotropic states. The thermal performances of the materials through heating/cooling cycles will be scrutinized using a combined IR-DSC operando technique.

The two laboratories are therefore expecting two PhD positions: one will be essentially localized at the LOMC, and the other at the LCS. These two thesis will nevertheless strongly interact and this interaction will be paramount for the success of the project. As an example, the diffusive aspects of the materials during processing will be analyzed using two complementary techniques: SAXS and diffusion RMN. The candidates will therefore need a good knowledge in polymer physical chemistry and/or any of the above-mentioned analytical techniques. They will also need to be good communicants. This project is funded by the laboratory of excellence LABEX EMC3 (Energy Materials Clean Combustion Center), and trips to international conferences are forecasted. The project will start in September 2022. The grants will cover 36 months of work for each thesis.

LOMC PhD position:

The candidate will have a Master degree or equivalent and will have a basic knowledge in polymer physical chemistry, crystallography or materials engineering. He or She will prepare samples and implement crystallographic techniques (SAXS and WAXD). More specific skills in one of these fields will be an asset, as well as preliminary knowledge on the Python programming language.

Location: The position is based at Le Havre University (Le Havre, Normandy, France), with frequent travels to ENSICAEN.

Funding: LABEX EMC3

Starting date of the thesis : September 2022

Contact: Please send your CV – including the contact details of at least two references – and cover letter to : Benoît Duchemin benoit.duchemin@univ-lehavre.fr (02.35.21.71.54)

LCS PhD position:

The candidate will have a Master degree or equivalent and will have a basic knowledge in physical chemistry and in spectroscopy. He or She will implement spectroscopic characterization techniques (in particular FTIR and NMR) and multivariate data analysis using python or matlab codes. More specific skills in one of these fields will be an asset.

Location: The position is based at ENSICAEN (Caen, Normandy, France).

Funding: LABEX EMC3

Starting date of the thesis : September 2022

Contact: Please send your CV – including the contact details of at least two references – and cover letter to : Arnaud TRAVERT – arnaud.travert@ensicaen.fr
