Abstract Cold physical plasma is a partially ionized gas that generates various components identified as potential anticancer compounds. Due to its topical application, cold plasmas are suitable, especially in dermatological applications. We, therefore, tested the effects skin cancer cells vitro . An atmospheric pressure argon jet was used source. The exposure alone reduced metabolic activity a...

This study analyses the in uence of the argon ow on the Plasma Enhanced Chemical Vapor Deposition (PECVD) of silicon oxide thin lms by using TEOS as silicon source. The argon ow increases the deposition rate, however it also can creates some defects in the deposited lm. Several characterization techniques were used to analyze the deposited lms. The presence of argon, in the gas phase, modi es t...

OBJECTIVE To evaluate the efficacy, safety and medium-/long-term clinical course of patients undergoing endoscopic treatment with argon plasma coagulation for hemorrhagic radiation proctopathy. DESIGN Descriptive, retrospective study with medium- and long-term follow-up. PATIENTS, MATERIAL AND METHODS Ten patients were treated with argon plasma coagulation for hemorrhagic radiation proctopa...

Dental plaque critically affects the etiology of caries, periodontitis and periimplantitis. The mechanical removal of plaque can only be performed partially due to limited accessibility. Therefore, plaque still represents one of the major therapeutic challenges. Even though antiseptic mouth rinses reduce the extent of biofilm temporarily, plaque removal remains incomplete and continuous usage c...

A magnetically enhanced radio-frequency (rf) plasma source operating on water vapor has an extensive list of potential applications. In this work, the use of a rf plasma source to dissociate water vapor for hydrogen production is investigated. This paper describes a rf plasma source operated on water vapor and characterizes its plasma properties using a Langmuir probe, a residual gas analyzer, ...

Polystyrene nanoring arrays with outer diameters ranging from 130 to 230 nm were fabricated using low cost and simple fabrication techniques, including nanosphere lithography, argon plasma treatment, immersion in organic solvents and sonication. These nanorings were developed from polystyrene nanospheres pre-assembled on substrates. Scanning electron microscopy revealed that the argon plasma tr...

In this work, applicability of Particle in Cell-Monte Carlo Collisions (PIC-MCC) simulation method for better understanding of the plasma physical mechanisms and real important aspects of a plasma column driven by surface wave plasma discharges that is used in plasma antennas is examined. Via the implementation of geometry and physical parameters of the plasma column to an Object Oriented PIC-M...
