Prof. Przemysław Sanecki and Piotr Skitał are focused on research in the field of electrode kinetics, in particular investigation and numerical modelling of complex multi-electron electrode processes [1-15]. The catalysis/inhibition of electrode process and adsorption phenomena is also in the area of interest. The team cooperates with prof. Krysztof Kaczmarski, the specialist in numerical modelling in physical chemistry and technology.
