About COST

COST (European Cooperation in Science and Technology) is a pan-European intergovernmental framework. Its mission is to enable break-through scientific and technological developments leading to new concepts and products and thereby contribute to strengthening Europe’s research and innovation capacities. It allows researchers, engineers and scholars to jointly develop their own ideas and take new initiatives across all fields of science and technology, while promoting multi- and interdisciplinary approaches. COST aims at fostering a better integration of less research intensive countries to the knowledge hubs of the European Research Area. The COST Association, an International not-for-profit Association under Belgian Law, integrates all management, governing and administrative functions necessary for the operation of the framework. The COST Association has currently 36 Member Countries.

Objectives of the Action TD1208

The main objective of this Action is to bring together a high level of experimental, simulation and theoretical expertise available around Europe in order to improve the knowledge of basic processes responsible for initiating and sustaining discharges in/on liquids and as well as to facilitate coordination and interdisciplinary exchange of knowledge and know-how between researchers from different scientific fields and countries in the field of electrical discharge plasmas in contact with liquids. The Action’s participants will exchange relevant scientific results and progress, educate students, share facilities for an optimized use of resources and promote innovation through their industrial links. The overall scientific challenge is the development of control strategies for producing plasma-liquid environments that are capable of delivering useful processes and species. The scientific challenge embodies a number of fundamental questions that relate to the basic principles of discharge generation and their reactive species. These fundamental questions are addressed within the following Action’s secondary objectives:

  1. Understand discharge ignition mechanisms in liquid phase
  2. Identify and understand fundamental physical phenomena in the plasma-liquid interaction
  3. Identify the dominating chemical processes in liquids initiated by plasmas
  4. Develop physical-chemical models linked to the topic
  5. Control and utilize the strong non-equilibrium chemistry initiated by plasma-liquid interactions
  6. Develop strategies for specific interdisciplinary applications of plasma-liquid systems

The complexity of these research topics requires co-operation of scientists from various fields including scientists and engineers from physics, chemistry, materials science and engineering, and additionally needs the involvement a number of equipment facilities. The research topics are strongly inter-linked and their realization will be accomplished through the four Working Groups (WGs) that are outlined below.

Working Groups

WG 1: Plasmas generated directly in the liquid phase

WG1 Leader: Antoine Rousseau, Ecole Polytechnique, Palaisseau, France

This WG focuses on investigation of plasmas generated in liquids and gaseous bubbles and foams and using different electrode configurations and power supplies, discharge plasma diagnostics, physical phenomena associated with electrical breakdown in liquid environment, and chemical characteristics of the discharge plasma products in liquid and gaseous phase.

WG 2: Atmospheric plasmas interacting with liquids

WG2 Leader: Petr Lukes, Institute of Plasma Physics AS CR, Prague, Czech Republic

This WG focuses on plasmas that are generated in the gas phase but in contact with a liquid, including configurations where one or both electrodes are outside the liquid and configurations where the plasma-liquid interactions occur due to droplets introduced into the plasma environment. The main topics include research of fundamental physical phenomena in plasma-liquid interactions, discharge diagnostics, chemical processes and analyses of the discharge products in liquid and gaseous phase and at gas-liquid interfaces.

WG 3: Elementary physical and chemical processes initiated in liquid phase by electrical discharges

WG3 Leader: Dragana Maric, Institute of Physics, Belgrade, Republic of Serbia

This WG focuses on research of elementary physical and chemical processes initiated in liquid phase by electrical discharge, elementary kinetic reactions, measurement/calculation of cross section sets for electron driven processes, transport rate coefficients, transport in liquids, elementary processes at plasma-liquid boundary, and numeric modeling of physical and chemical processes in plasma-liquid systems.

WG 4: Interaction of plasma reactive species with materials and surfaces

WG4 Leader: Stephan Reuter, Leibnitz Institute for Plasma Science and Technology (INP Greifswald), Greifswald, Germany

This WG pays particular attention to developing new technologies. These include decomposition of hardly destructible water pollutants, and water sterilization, nanoparticle synthesis and surface treatment of materials will be performed under various specially designed configurations. The synthesis of various organic compounds will be studied with respect to their possible future applications. The treatment of biological matter (bacteria, moulds, skin) will also be examined, leading to new medical treatment procedures. Based on the application field area the WG4 is divided into 4 subgroups:

WG4.1: Applications in water treatment and advanced oxidation processes.

WG4.1 Leader: Mirosłav Dors, The Szewalski Institute of Fluid Flow Machinery Polish Academy of Sciences, Gdansk, Poland

WG4.2: Biomedical applications.

WG4.2 Leader: Stephan Reuter, Leibnitz Institute for Plasma Science and Technology (INP Greifswald), Greifswald, Germany

WG4.3: Applications in surface treatment and in nanosciences.

WG4.3 Leader: Davide Mariotti, University of Ulster, Ulster, United Kingdom

WG4.4: Organic chemistry applications.

WG4.4 Leader: Felipe Iza, Loughborough University, Loughborough, United Kingdom
