GREMI • UMR 7344
Energetics of Ionised Environments Research Laboratory

The GREMI laboratory (Research Group for the Energetics of Ionised Environments) is a Joint Research Unit (UMR 7344) of the  CNRS (INSIS, section 10) and the University of Orléans, created in 1982. The GREMI is mainly located on the University of Orléans campus. In 2009, the LASEP located in Bourges joined the GREMI. Part of the laboratory is therefore located in Bourges (IUT site).

Cosmétosciences research topic:

Biological activity and safety

The approaches have been built on multidisciplinary foundations in physics, optics, chemistry, materials and energetics. They cover a set of applications that mainly fall within engineering for energy, electronics, biology, decontamination, metrology, the flow modification and aviation safety.
The research is of a fundamental nature and is applied in a spirit of ‘understanding to design’ in order to rise to societal challenges. While the stock of instruments is rich, the research also rests on modelling and digital simulation, which are becoming increasingly important.

The GREMI’s research is conducted by 2 teams. One team is involved in Cosmétosciences

Plasmas team for the environment, the living and safety (PEVS)
The topics studied in this area of focus relate to the development of plasma sources for specific applications. They include all the issues related to the safety of property, people or the environment.:

  • Plasma-living environment interaction (microbiological safety)
    – Sterilisation and decontamination ;
    – Bioengineering: treatment/prevention of bacteria and biocorrosion, plasma medicine (anti-tumour effect), cosmetics;
    – plasma/plant interaction (agro-food).
  • Thermal plasma processes (safety of property and people)

    – Pulsed arcs (lightning, arcs from faults, arcs from power cuts, arc tracking);
    – Electrode phenomena;
    – Laser induced plasmas (LIBS, fuel lighting).
  • Treatment and enhancement of effluents (environmental safety)
    – Decontamination and cleaning of gases (treatment of exhaust gases), liquids (residues of medicinal products) and surfaces;
    – enhancement of gases (biomass products) and liquids (activated water for agriculture or to prevent biofouling);
    – Plasma ignition, aids combustion, controls flow.
