Operation • Electrodeless inductive coupling allows use with chemically reactive gases • Low power (300 mW 3 W), low voltage (< 20 V) • Gas pressure: 0.1 10 Torr (13 1300 Pa) • Argon ion density: 1010 1011 cm-3 • Electron temperature: 20,000 50,000 K • Non-equilibrium plasma allows operation near room temperature, however. MEMS Plasma Generator A low power, electrodeless plasma source on a chip...

Significant progress has been made in the characterization of the necessary parameters required to create an effective Radio Frequency (RF) plasma based electron source. Such a device has the promise of comparable current densities to and longer operational lifetimes than hollow cathodes. The operational lifetime of hollow cathodes is ultimately limited by cathode deterioration. RF sources prov...

AIMS To describe the use of argon plasma coagulation (APC) for radical resection of lipomas and hamartomas in large airways. METHODS Eight patients (7 males and 1 female) were retrospectively reviewed. Data extracted included patient demographic characteristics, type and location of lesion, type of anesthesia used, number of APC sessions required, complications, length of hospital stay, and o...

Plasma environments constitute powerful tools in materials science due to their operation as thermal and chemical reactors. A microwave, atmospheric argon plasma driven by surface waves has been used for synthesizing carbon nanostructures by passing vaporized ethanol through the plasma. Graphene sheets and carbon nanoparticles have been selectively synthesized through the control of the outlet ...

Dye sensitized solar cell was assembled using TiO2 nanoparticle with argon-nitrogen plasma treatment and CuBi2O4 sputtering electrode prepared by plasma irradiation. The electric property of the solar cell fabricated by plasma treated TiO2 nanoparticle was improved because the physical and chemical property of TiO2 particles affected from the nitrogen plasma treatment

Introduction. Technologies related to the use of low-temperature atmospheric plasmas are developing at a rapid pace. Creation new plasma sources for specific applications requires monitoring dynamic processes in such discharges with high time resolution. Electron concentration is one most important characteristics, which can be very low pressure plasma. However, methods currently available diag...

INTRODUCTION Endoscopic argon plasma coagulation (APC) is gaining widespread usage but its risk is underreported. CLINICAL PICTURE A 74-year-old man who received radical radiotherapy for gastric carcinoma 6 months ago was admitted for anaemia and maelena. Gastroscopy revealed haemorrhagic radiation gastritis. Endoscopic APC was performed but terminated when he complained of severe epigastric ...
