Low-energy linear oxygen plasma source [PDF]
Review of Scientific Instruments, 2007 A new version of a constricted plasma source is described, characterized by all metal-ceramic construction, a linear slit exit of 180mm length, and cw operation (typically 50kHz) at an average power of 1.5kW. The plasma source is here operated with oxygen gas, producing streaming plasma that contains mainly positive molecular and atomic ions, and to a ...

A reaction mechanism for oxygen plasmas
Plasma Sources Science and Technology, 2023 Abstract This work presents a reaction mechanism for oxygen plasmas, i.e. a set of reactions and corresponding rate coefficients that are validated against benchmark experiments. The kinetic scheme is validated in a DC glow discharge for gas pressures of 0.2–10 Torr and currents of 10–40 mA, using the 0D LisbOn KInetics simulation tool ...

Oxygen plasma modification of polyurethane membranes
Journal of Materials Science: Materials in Medicine, 2002 Polyurethane membranes were prepared under nitrogen atmosphere by using various proportions of toluene diisocyanates (TDI) and polypropylene-ethylene glycol (P) with addition of no other ingredients such as catalysts, initiator or solvent in order to achieve medical purity. Effects of composition on mechanical properties were examined.

Electron energy loss in oxygen plasmas
The Astrophysical Journal, 1994 The results of calculations of the energy deposition of energetic electrons in oxygen plasmas are given. In a pure oxygen plasma even with large fractional ionization, much of the electron energy results in the production of additional ionization and excited electronic states.

Effect of Microwave Plasma Pre-Treatment on Cotton Cellulose Dissolution
Molecules, 2022 The utilization of cellulose to its full potential is constrained by its recalcitrance to dissolution resulting from the rigidity of polymeric chains, high crystallinity, high molecular weight, and extensive intra- and intermolecular hydrogen bonding ...
