Cold plasma brush generated at atmospheric pressure
Review of Scientific Instruments, 2007A cold plasma brush is generated at atmospheric pressure with low power consumption in the level of several watts (as low as 4W) up to tens of watts (up to 45W). The plasma can be ignited and sustained in both continuous and pulsed modes with different plasma gases such as argon or helium, but argon was selected as a primary gas for use in this work ...

Microbiological treatment of water by cold plasma at atmospheric pressure
Global NEST International Conference on Environmental Science & Technology, 2022Ensuring the world's population access to drinking water is one of the millennium's challenges, for although our planet is made up of 70% of water, poor distribution and water quality are problems that concern world leaders, being among the objectives of development 2030 agenda set by the ONU. The proposed work aimed at the microbiological treatment of

DC-excited cold atmospheric pressure plasmas
Czechoslovak Journal of Physics, 2006In view of the increasingly wide range of applications, different approaches are nowadays being investigated to generate non-thermal plasmas operating at atmospheric pressure. In this paper the focus is on DC-excited atmospheric pressure discharges in air. The basic electrode configuration is that of a pin-to-plate corona.

Atmospheric pressure cold plasma as an antifungal therapy
Applied Physics Letters, 2011A microhollow cathode based, direct-current, atmospheric pressure, He/O2 (2%) cold plasma microjet was used to inactive antifungal resistants Candida albicans, Candida krusei, and Candida glabrata in air and in water. Effective inactivation (>90%) was achieved in 10 min in air and 1 min in water.

Characteristics of RF Cold Plasma at Atmospheric Pressure
Plasma Science and Technology, 2007The characteristics of a stable discharge at atmospheric pressure is investigated. The plasma source consisted of two closely spaced parallel-plated perforated electrodes, driven by a radio frequency power to generate a uniform cold plasma in Helium at atmospheric pressure. Both alpha and gamma modes were clearly observed.
