    The Institute of Materials Science of Mulhouse (IS2M) is a joint research unit CNRS-University of Haute-Alsace (UMR 7361). Thanks to its multidisciplinary character, its scientific impact and its interactions with other fields, the laboratory is one of the structuring forces of the materials landscape and their applications in the academic and industrial world, both at the regional and national levels. IS2M has been able to define its identity and acquire an undeniable visibility in the highly competitive international research landscape.

    IS2M owes its reputation to the excellence of its research, to the scientific influence of its researchers and teacher-researchers and to the great professionalism of its research support staff. It also owes it to the attractiveness of the training courses in which the teachers/researchers are involved and to the professional success of its doctoral and post-doctoral students.

    The general objective of the Institute is to advance the knowledge front in the field of materials.

    The research project will be conducted in the PHOTON team led by Olivier Soppera. This team develops materials and associated processes of micro- nanostructuring by photochemical processes. The project is part of the team's sol-gel photostructuring activities.

    This theme will be conducted in collaboration with a team at the University of Marseille (IM2NP / AMU) in the framework of an ANR project.

    Among the major technological achievements of the last century in nanofabrication, laser-assisted processing methods are undoubtedly the most advanced. They have enabled significant progress in the elaboration of nanostructures, but great challenges remain to improve performance in terms of quality, versatility, resolution, throughput, cost and achievable morphologies. One of the current trends, but still limited in practical applications, is their use to pattern inorganic materials. Among other works, a method based on Deep-UV laser irradiation for patterning and curing hybrid materials into metal oxide nanostructures has been developed at IS2M. In the particular case of TiO2, fully inorganic metal oxide patterns can be obtained at room temperature. So far, these results have been limited to basic dense 2D structures. In parallel, 3D printing technology has emerged as a powerful additive manufacturing (AM) approach for the rapid, precise, and customized fabrication of objects with complex geometries at the macro, meso, and microscopic scales. Until today, different techniques have been developed. Among others, the 3D printing of polymers by UV assisted techniques or by wire fusion has developed a lot. Concerning the shaping of inorganic materials such as metal oxides, only a few works have been reported. The main difficulty comes from the processing of these materials, which makes them difficult to use in powder or solution fusion technologies. In this thesis project, we propose a new approach to realize the fabrication of 2D and 3D metal oxide structures, from solutions, using direct laser writing. We aim at multi-scale structural control and hierarchical functionalities, with a very high control and versatility on the material structure.

    Additional comments

    The candidate should have a Master 2 level (or equivalent) in chemistry- physics, chemistry or physics. Theoretical knowledge in materials chemistry, nanomaterials and physical chemistry is required. Practical experience in a research laboratory on processing and characterizing (nano)materials by laser technologies is desired. Qualities such as autonomy, ability to work in a team, ability to communicate (including in English) are essential.
