The scientific research activity is directed over plasma study, particularly over the radiofrequency (RF) plasmas generated at atmospheric pressure in argon, helium, air ... .

The three main study directions:

building of devices for generating of:

Inductively Coupled Plasma (ICP) - 27.12 MHz, 1-3 kW

Capacitively Coupled Plasma (CCP) - 10 MHz, 0.5-80 W

Dielectric Barrier Discharge (DBD) - 20 kHz-2 MHz, 1-20 W
Plasma in/on Liquids - 10 MHz, 16 W

the main principle of generation:

plasma is the intrinsic part of a resonant LRC circuit

fundamental studies over the generated plasmas: plasma parameters, electrical modelling, studies based on Fourier analysis of the influence of the plasma on the waveform of generated oscillations by the RF oscillator.

applications of generated plasmas:

spectral sources for analysis of liquid samples

spectral sources for direct analysis of conductive an nonconductive solid samples

                      treatment of microorganisms by non-thermal capacitively coupled plasma
                    nanoparticle synthesis
                    dyes degradation
