1. Computational framework for studying charge transport in high-voltage gas-insulated systems
Abstract : Electrical switchgear industry dealing with transmission and distribution of power is strongly affected by the changing dynamics of climate control. Their main contribution to the global warming is through SF6 gas, having a GWP of 23500 (times of CO2). SF6 plays an important role in providing electrical insulation for these high voltage systems.

2. Modelling of cathode-plasma interaction in short high-intensity electric arc : Application to Gas Tungsten Arc Welding
Abstract : In arc welding the quality of the weld is strongly influenced by the thermal history of the workpiece which is itself governed by the electric arc heat source. The models for predicting weld properties thus need a good evaluation of the distribution of the heat input from thearc to the workpiece. READ MORE

3. Optical Diagnostics of Non-thermal Plasmas and Plasma-assisted Combustion
Abstract : Non-thermal plasma is regarded as a collection of free electrons, ions and neutral particles that are not at local thermodynamic equilibrium. The high-energetic electrons formed in non-thermal plasmas are capable of generating chemically active species and modifying chemical kinetics in practical applications. READ MORE

4. Engineered ion-bombardment as a tool in thin film deposition
Abstract : Energetic-ion bombardment has become an attractive route to modify the crystal growth and deposit high quality thin films. In high-power impulse magnetron sputtering (HiPIMS) where the discharge is characterized by a significant amount of ions of the sputter-ejected atoms, energetic-ion bombardment effects could not be underestimated.

5. Quantitative Spectroscopy of Gas Phase Reactions at Elevated Temperatures
Abstract : Gas phase reactions at elevated temperatures are versatile tools for material manufacturing and energy conversion. They are of great commercial interest, but they often entail hazardous impacts on the environment. There is consequently a pronounced need for the further develpment of processes utilising these types of reactions. READ MORE
