The PEVS Approach in Short

Themes developed in this approach focus on the development of plasmas for specific applications. They all concern issues regarding the safety of goods, persons or the environment:

The plasma/medicine field has undoubtedly become a strength of the laboratory. Research is now more broadly focused on the plasma/living interaction (cells, bacteria, microorganisms) including sterilization, anti-biofouling (curative), help for germination, etc.

In most cases, this plasma/ living substance interaction takes place through an aqueous layer, and therefore involves a plasma/liquid interaction stage. Common plasma/liquid interaction phenomena are also found in the treatment and recovery of liquid effluents: elimination of drug residues, activated water for decontamination or agriculture (production of nitrates, etc.). Whatever the application and the type of discharge (plasma jet, non-thermal plasmas at atmospheric pressure, etc.), the study of the physical chemistry of this complex interaction is a subject that brings together researchers from the PEVS approach. This joint fundamental research on plasma/liquid interaction, which has already begun on a number of projects, is set to expand.

The laboratory's long-standing “thermal plasma processes” theme is moving in new directions, drawing on the experience gained in understanding and controlling steady-state discharges. The aim is to study impulse arcs (cut-off arcs, fault arcs, lightning) and their effects on their environment (thermal damage, ablation and aging of contacts, energy transfer to electrodes, radiation, etc.), with a view to their remediation. In this sense, the research carried out will relate to the electrical safety of people and equipment.
