Plasma processing of PET in an oxygen decoupled plasma source
2014 IEEE 41st International Conference on Plasma Sciences (ICOPS) held with 2014 IEEE International Conference on High-Power Particle Beams (BEAMS), 2014Samples of poly(ethylene terepthalate) (PET), 200 mm, were exposed to an energetic oxygen discharge from a decoupled plasma source, in order to modify local surface properties. Samples were placed at two distances, 13 cm and 20 cm, from the top of the discharge coil to assess the interaction between the sample and the DPS discharge.

Plasma Leakage of Oxygenators in ECMO Depends on the Type of Oxygenator and on Patient Variables
The International Journal of Artificial Organs, 2005This study was conducted to identify the causes of plasma leakage of oxygenators in extra corporeal membrane oxygenation (ECMO). From 1996 through 2002, 91 oxygenators were used in 62 patients undergoing ECMO for respiratory and/or cardiac failure. Several types of oxygenators were used (Medtronic Maxima, Minima, PRF, Medos Hilite).

Selective Anodic Oxidation of Silicon in Oxygen Plasma
IEEE Journal of Solid-State Circuits, 1980Plasma-enhanced oxidation process at low temperature was studied for the selective oxidation of silicon. Silicon dioxide films as thick as 1 /spl mu/m were routinely obtained at the substrate temperature of 600/spl deg/C. The oxidation was found to proceed through the motion of both oxygen and silicon ions and/or their vacancies under the electric ...

Proton and oxygen plasmas at Uranus
Journal of Geophysical Research: Space Physics, 1987Despite the presence of several large, icy moons within the Uranian magnetosphere, the Voyager 2 spacecraft did not detect any heavy ion plasma. This paper estimates the heavy ion density that would be consistent with a heavy neutral torus formed by photosputtering, charged particle sputtering, and micrometeoroid impact vaporization of icy surfaces on ...

Oxygen Plasma-Treatment Effects on Si Transfer
Langmuir, 2005Oxygen plasma-treatment is commonly used to increase the hydrophilicity of poly(dimethylsiloxane) (PDMS) stamps used for microcontact printing (muCP) aqueous-based inks. Review of the literature reveals that a wide range of plasma parameters are currently employed to modify stamp surfaces.

Anodization of Silicon in RF Induced Oxygen Plasma
Japanese Journal of Applied Physics, 1979Silicon dioxide films were grown on Si substrates by anodization in RF induced oxygen plasma at the pressure of 0.2 Torr and temperature of 600°C. SiO2 films of 1 µm in thickness were obtained within one hour. The selective oxidation was studied and Al2O3 was found to be effective in masking against the oxidation.

Macroscopic modeling of oxygen plasmas
Journal of Vacuum Science & Technology A: Vacuum, Surfaces, and Films, 1990This paper describes a macroscopic model of parallel-plate, radio frequency (rf), oxygen plasma discharges. The model predicts fundamental plasma characteristics as a function of controllable parameters such as pressure, power, and electrode spacing.

Influence of oxygen in plasma nitriding
International Heat Treatment and Surface Engineering, 2009AbstractThe development of low temperature nitriding treatments to enhance wear resistance over the past 40 years is reviewed. The progress achieved is illustrated with evidence from extensive laboratory investigations and industrial trials on textile machine components and other parts.

Platelet Storage: An Assessment of the Requirements for Plasma and Oxygen
Transfusion, 1981Platelets from several units of plasma were pooled, and then resuspended either as platelet concentrate (PC) (60 ml) or as platelet rich plasma (PRP) (220 ml) and followed during 72 hours of storage at 22 C. Aggregation, pH, and hypotonic shock response are better maintained in the larger volume of plasma.

Cleaning of Porous Aluminium Titanate by Oxygen Plasma
Plasma Chemistry and Plasma Processing, 2006The removal of organic contaminants from porous Al2TiO5 during treatment in oxygen plasma was studied by optical emission spectroscopy (OES). The samples of Al2TiO5 were immersed into water emulsion of mineral oil for 3 hours to get soaked. Then they were thoroughly cleaned in ultrasound to remove oil from the surface.
