Institute of Materials Science of Mulhouse (IS2M)
The Institute of Materials Science of Mulhouse (IS2M) is a joint research unit CNRS-University of HauteAlsace (UMR 7361). Thanks to its multidisciplinary character, its scientific impact and its interactions with other fields, the laboratory constitutes one of the structuring forces of the Materials and their applications landscape 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 brings together nearly 200 people. There are 93 permanent staff including 15 CNRS researchers, 48 teacher-researchers, 24 CNRS ITA, 6 UHA BIATSS and ~80 PhD and post-doctoral students/year.
IS2M is attached to two CNRS Institutes: the main one is the Institute of Chemistry and the secondary one is the Institute of Physics. Section 15 of the CNRS is the main section of the laboratory. The CNRS researchers are attached to sections 3, 11, 13, 14 and 15 and the teacher-researchers to sections 28, 31, 32, 33, 62 and 68. In addition, more than 100 trainees/year are added to this staff, from Bac + 1 to Bac + 5.
The results of our research are the subject of ~190 publications/year. The work is also valorized through patents (~6/year) and CNRS press releases (~5/year).
An asset of IS2M is its dense network of academic and industrial collaborations. Nearly 30 academic partnerships, including 10 international ones, and 20 industrial partnerships are established each year.
Finally, IS2M, labeled Carnot Institute, is a member of the Carnot Institute MICA (Materials Institute Carnot Alsace), of the Research Federation ‘Materials and Nanoscience of the Grand-Est’ (FR 3627), of the National Laboratory of Excellence ‘Store-Ex’ in the field of electrochemical energy storage and of the Interdisciplinary Thematic Institute Hierarchical and Functional Materials ‘HIFunMat’ for health, environment and energy of the University of Strasbourg.
PHOTON Research Team at IS2M
The IRP project will involve the team PHOTON headed by Dr. Olivier Soppera. The research activity of thisteam is focused on the development of materials and processes for micronano-fabrication, assisted by light. Basically, the concept is to use light as a tool to shape the matter in photo-activated additive fabrication processes. One aspect of his research was devoted to develop new strategy for photofabrication. The main objective is to push forward the limits of conventional photolithography:
Extending the wavelength range towards…
- Deep-UV for high resolution/wide area patterning for advanced photoresists for microelectronics (Adv. Mater. 2009), modification of surface chemistry at nanoscale (Langmuir 2010), directed selfassembly (Langmuir 2013) or biosurfaces (Langmuir 2009)
- Near-IR (800 nm to 1550 nm) for integrating self-written optical elements for photonic applications (Opt Lett 2009, patent EP15307046 2015), direct write metal oxide from sol-gel thin films (Adv. Mater. 2018, ACS AMI 2020, Adv. Opt. Mater. 2021).
- Confining the photopolymerization to the nanoscale. Optical Near-Field Photopolymerization is used to confine the photopolymerization far below the diffractions limits. Not only light induced polymerization was demonstrated with dimensions down to several nanometers (Phys. Rev. Lett. 2007, ACS Nano 2010) but also the photochemistry at the nanoscale was investigated, revealing new processes due to the high spatial confinement of photoinduced reactions (J.Am.Chem.Soc. 2011, JPhysChemC 2021). The concept was recently applied to photoATRP and Quantum Dots
(Materials Today2020, Nat. Comm2020). - From 2D to 3D fabrication. Strategies for 3D fabrication have known an increasing interest during the last years. I am involved in projects using conventional 3D printers (laser direct write, Digital Light Processing, 2-photon stereolithography) or for developing new strategies like frontal photopolymerization for optical object fabrication. (J Polym Sci Pol Chem 2008, patent PCT/FR2017051784 2017 with Essilor International).
The second aspect is related to the development of new photoactivable functional materials that are compatible with this advanced micro-nano-fabrication setup. The idea is to shape functional materials with light so that the final properties of the micro-nano-objects will be given by the material constitution and microstructure. In this field, some advances can be highlighted on :
- Hybrid organic/inorganic materials for their optical (Adv. Mater. Interfaces 2016), electrical (patent EP15166292 2015) or magnetic properties (Adv. Mater. Interfaces 2017). Metal-oxo clusters can also be convert to metal-oxide at room temperature for electronic (Sci. Rep. 2015). This topic is developed in collaboration with prof. Zan.
- Photocrosslinkable Molecularly Imprinted Polymers allowed to produce selective and sensitive biosensors thanks to microstructuration (Adv. Mater. 2013, Angew. Chem. Int. Ed. 2013, Adv. Mater. 2016).
- Green materials and processes: developing sustainable materials and green technologies is integrated in the new research projects. Recent example includes the development of recyclable photoresist (Angew. Chem. Int. Ed 2022) or biosourced photoresists such as chitosan (ACS Appl. Polym. Mater. 2022).
In all cases, the work starts from the understanding of the fundamental photoinduced processes at the molecular scale. Specificities linked to the spatially controlled irradiation are taken into account (diffusion processes for example). Special care is devoted to the analysis of the final material. Finally, applications in optics, photonics, biosensors, gaz sensors or biology are also motivation for all this research.
