Vos missions en quelques mots
You will be in charge of:
This postdoctoral position is part of the Bio-Electro project, funded by the M-ERA.NET, which involves 8 European partners. The Bio-Electro project aims at preparing bio-based and biodegradable electrodes intended for sustainable electrophysiology, using electrocardiography (ECG) as a user case. The new biodegradable electrodes will be composed of nanocellulose (NC) hydrogels or aerogels in combination with biodegradable electroconductive additives and nanoinks allowing efficient ion-to-electron transduction. The electrodes will be produced following new sustainable manufacturing technologies adapted to the generated materials.
The postdoctoral position will focus on the preparation and characterization of cellulose-based aerogels, showing different pore size and morphology.
Aerogels are materials derived from hydrogels in which the liquid phase is replaced by a gas in mild conditions. They are ultra-light, highly porous (> 90%) and present a high specific surface area. Nanocellulose aerogels and their composites have already demonstrated conductivity for electrode fabrication, however, they have not been explored for ECG applications. The postdoctoral position will therefore focus on controlling directional porosity and 3D stability of nanocellulose-based aerogels that facilitate conductivity for electroconductive materials.
This postdoctoral position aims at investigating the arrangement of nanocelluloses as porous architectures. Nanocellulose-based porous materials will be prepared by the freeze-drying process. Two strategies will be used to control pore size and morphology: non-directional (ND) and unidirectional (UD) freezing.1, 2 In the ND procedure, ice crystals grow from the outside to inside the gel in an isotropic manner leading to a honeycomb structure. In the UD procedure, ice crystals are growing from the bottom to the top inside the gel (anisotropic manner), so that CNF densification occurs between ice crystal monoliths leading to lamellar structuration of CNFs wall. For this purpose, we propose the following objectives:
1. To prepare nanocellulose-based aerogels with controlled porosity by non-directional (ND) and unidirectional (UD) freezing.
2. To characterized the properties of aerogels: mechanical, water responsiveness, conductivity.

Qui sommes-nous ?
The French National Research Institute for Agriculture, Food, and the Environment (INRAE) is a public research establishment. It is a community of 12,000 people with more than 200 research units and 42 experimental units located throughout France. The institute is among the world leaders in agricultural and food sciences, in plant and animal sciences, and is 11th in the world in ecology and environment. INRAE’s main goal is to be a key player in the transitions necessary to address major global challenges. In the face of the increase in population, climate change, scarcity of resources and decline in biodiversity, the institute develops solutions for multiperformance agriculture, high quality food and sustainable management of resources and ecosystems.
Descriptif du service
You will be welcomed in the unit Biopolymers, Interactions and Assemblies (BIA) from INRAE. BIA is located at Géraudière campus (3 impasse Yvette Cauchois, 44316 Nantes). The BIA unit works with those involved in bioresource production to study the biological mechanisms that influence the quality of bioresources. At the heart of its expertise, BIA analyses the evolution of compositions and structures via fractionation, the impact of processes or formulation, and assesses product functionalities, both in technological terms and in terms of their environmental and human health impacts (https://eng-ur-bia.angers-nantes.hub.inrae.fr/).
