Research areas

Dr Slikboer focuses on experimental techniques to investigate the physics governing cold plasmas at atmospheric pressure and their applications. Cold plasmas are studied for a wide range of applications: for example, sterilization and treatment of biomedical samples (living tissue, wounds, cells, etc.), surface functionalization (wettability), and agriculture (green fertilizers). The reason for these numerous applications is the reactivity of the energized free electrons in the plasma while the heavy particles stay at ambient conditions. This means these plasmas are safe to touch while a cocktail of reactive species is produced (e.g. radical oxygen and nitrogen species in the air) combined with electric fields, metastables, ions and surface charges.

The experimental techniques used to investigate the breakdown dynamics and behaviour of the cold plasma include Mueller polarimetry, Thomson scattering, optical emission spectroscopy and flow visualization techniques like Schlieren imaging. Mueller polarimetry is used to exploit the Pockels effect of electro-optic targets, which allows the investigation of induced electric fields by the plasma when it interacts with a surface. Thomson scattering focuses on the electron properties of the discharge, giving an opportunity to measure the electron density and temperature. A recurring research goal involves gaining a better understanding of the physics that govern these plasmas with respect to breakdown dynamics, stability, and production of species. This aims to reach better controllability of the plasma-surface interaction, which is beneficial to all current and future applications.
