A non-thermal plasma (NTP) is a promising tool against the development of bacterial, viral, and fungal diseases. The recently revealed development of microbial resistance to traditional drugs has increased interest in the use of NTPs. We have studied and compared the physical and microbicidal properties of two types of NTP sources based on a cometary discharge in the point-to-point electrode configuration and a corona discharge in the point-to-ring electrode configuration. The electrical and emission properties of both discharges are reported. The microbicidal effect of NTP sources was tested on three strains of the bacterium Staphylococcus aureus (including the methicillin-resistant strain), the bacterium Pseudomonas aeruginosa, the yeast Candida albicans, and the micromycete Trichophyton interdigitale. In general, the cometary discharge is a less stable source of NTP and mostly forms smaller but more rapidly emerging inhibition zones on agar plates. Due to the point-to-ring electrode configuration, the second type of discharge has higher stability and provides larger affected but often not completely inhibited zones. However, after 60 min of exposure, the NTP sources based on the cometary and point-to-ring discharges showed a similar microbicidal effect for bacteria and an individual effect for microscopic fungi.

The removal of diesel exhausts by non-thermal plasma technology has been investigated focused on the simulation gas experiment at atmospheric pressure and room temperature for many years. However, the research for real diesel engine is need to be further studied. In the experiments, a non-thermal plasma (NTP) reactor was designed based upon dielectric barrier discharge. NO/NO2 conversion was studied as a function of the specific input energy (SIE) by varying the frequency and voltage applied on the NTP reactor through bench test. Results showed that NTP SIE was increased with the voltage at each frequency. The conversion of NO to NO2 was increased at higher NTP SIE. However, NO will further be converted to other active species but not only NO2.
