Applied Plasma/ Plasma Enhanced Reactive Systems

PhD student: Daniel Söderström
The applied plasma research is directed to novel concepts in plasma sources and to development of Plasma Reactive Systems and plasma processes. Non-conventional high density plasma sources based on the hollow cathodes and microwave and hybrid plasmas were developed by the group. Mechanisms of plasma reactive processes/systems and their relation to properties of process products are studied and evaluated in different applications.
The research covers both the low pressure reactive systems and plasma reactive technologies based on non-equilibrium (cold) plasmas at atmospheric pressure. Cold atmospheric plasma shows potential for applications in many areas, from nano- and bio- to material and combustion technologies and fuel reforming.
The program aimed to conversion and destruction of hazardous gases and other polluting and contaminating agents embraces plasma science, plasma chemistry and plasma chemical kinetics. The processes of gas treatment are developed for important environmental applications linked to energy production, automotive and aerospace industries, to metallurgy and to paint, dyeing and printing industries. The objective of the project is to contribute to effective pollution control.
Plasma can also be used for surface plasma treatment , structure modification, coating, cleaning, activation, passivation, disinfection, decontamination and synthesis of new materials. Vaporized and plasma activated species are delivered to the substrate or particles. Plasma gasification of particulate matter is being solved within the program devoted to energy efficient exhaust reduction. Plasma activated species can also condense, react and form coatings – functional, decorative, permeation barriers, protective coatings, etc. New biocompatible coatings are evaluated within the program testing high density plasma PVD.
Concepts developed by the Group:
- Magnets-in-Motion (M-M) concept
- in linear Hollow Cathodes
- Hollow Cathode Discharge
- Hollow Cathode Arc
- Target metal vapor discharges
- Metastable assisted processes
- Microwave Antenna (MWA) discharge
- Fused Hollow Cathode (FHC)
- Cold Atmospheric Plasma
- Hybrid Hollow Electrode
- Activated Discharge (H-HEAD)
- Cold Atmospheric Plasma applications
Our plasma reactors and systems are installed in the Ångström laboratory cleanroom and/or in a special laboratory devoted to cold atmospheric plasma research.
Plasma Science and Plasma Engineering deal with applications of gas discharge plasma to processes and devices. The Applied Plasma Group has been involved over the years with R&D in plasma sources, plasma processes and plasma applications ranging from surface plasma treatment to solution of environmental pollution problems.
