The GREMI laboratory (Research Group on the Energetics of Ionized Media) is a Joint Research Unit (UMR 7344) of the CNRS (INSIS, section 10) and the University of Orléans, created in 1982. The GREMI has been located on the Orléans campus, in the same building as the Polytech Engineering School, since 1998. In 2009, the Bourges-based LASEP joined the GREMI. Part of the laboratory is now located in Bourges (IUT site).
The laboratory has 22 teacher-researchers, 8 researchers, including 1 on permanent contract, and 11 permanent IT/BIATSS staff, as well as around 20 fixed-term contracts (doctoral students, post-docs and engineers).
The GREMI's research focuses on plasmas, as well as plasma and laser processes.
Approaches are built on a multidisciplinary basis in physics, optics, chemistry, materials and energy. They cover a wide range of applications, mainly in engineering for energy, electronics, biology, pollution control, metrology, flow modification and aeronautical safety.
Research is both fundamental and applied in the spirit of “understanding in order to design”, in response to societal challenges. While research is based on a wide range of instruments, modeling and digital simulation are becoming increasingly important.
Scientific organization
Research activities focus on:
- Plasmas created by all types of discharges and their applications, from their fundamental properties to the development of complete processes.
- New materials (thin films and nanomaterials), surface modification by plasma and/or laser to exacerbate or change their properties, the design of reliable specific benches for determining these properties, and assembling to obtain demonstrators.
The laboratory is structured around 2 main scientific axes:
