Nanosecond Plasmas in Liquids - How do they ignite ?

Discharges in liquids gained a huge interest over the last decades as they can be used for example for wastewater treatment, for nanoparticle formation as well as for biomedical applications . These types of discharges are appealing, because they produce a range of reactive species like OH and H2O2 inside water. The in-liquid discharges are usually ignited in a pin-to-pin or pin-to-plate configuration using a high voltage (HV) pulse applied to an electrode.
