High frequency gas discharge plasma reactions of styrene and methyl methacrylate at low pressure have been studied mass spectrometrically. When styrene was used as a monomer, the most important reaction was plasma state polymerization; some decomposition of styrene and the formation of a small amount of C2H4 were detected. Under the same conditions, methyl methacrylate was decomposed mainly to CO, CO2 and C2H4.

A Study of Crystallization in Plasma Modified Polypropylene Mansuroglu, Dogan; Mecit, Giray; Uzun Kaymak, İlker Ümit (2019-01-01) A capacitively coupled radio-frequency plasma discharge is used to improve the surface properties of Polypropylene. The changes in the surfaces are investigated for various plasma discharge parameters. After the plasma modification, the polypropylene material transforms into a para-crystalline form and shows the properties of the monoclinic crystals dominantly, observed using the X-ray diffraction measurements. The results indicate significant improvements in the crystallinity after the plasma exposure. The...
Micro processing by intense fast electron beam Goktas, H; Kirkici, H; Oke, G; Udrea, M (2001-06-22) Generation of intense electron beams by superposing two discharges, namely a low pressure do glow discharge and a high current pulsed discharge at pressures and voltages very similar to that of the pseudo-spark gap devices, has been reported previously [1, 2]. The small diameter, high peak current and short pulse length are the characteristics of the electron beam generated using this technique. In this technique, no high vacuum facilities are necessary, and many applications such as micro processing, X-ray...
One-dimensional fluid and hybrid numerical analysis of the plasma properties in the discharge channel of a Hall thruster YUNCULER, Cinar; Rafatov, İsmail; Ulusen, DEMET (2018-01-01) One-dimensional fluid and hybrid fluid-kinetic numerical codes are developed and applied to the analysis of axial distributions of plasma properties in the discharge channel of a Hall-effect thruster. Within the hybrid model ions are described by the kinetic Vlasov equation, while electrons and neutral atoms are treated as fluids. The results obtained from fluid and hybrid models are compared. Different operating regimes such as damped, periodic, and aperiodic irregular oscillations about the stationary sta...
Self-consistent treatment of gas heating in modeling of a coaxial DBD in atmospheric pressure CO2 Zhou, Chen; Yuan, Chengxun; Kudryavtsev, Anatoly; Yasar Katircioglu, T.; Rafatov, İsmail; Yao, Jingfeng (2023-01-01) This work is devoted to the numerical study of characteristics of dielectric barrier discharge maintained in a coaxial reactor in atmospheric pressure CO2. The numerical model is based on the drift-diffusion theory of gas discharges, and takes into account the gas heating in a self-consistent manner. The effect of incorporating gas heating into the discharge properties, specifically, on CO2 decomposition, is investigated for wide range of amplitude and frequency of the applied voltage. Calculations revealed...
Transition from homogeneous stationary to oscillating state in planar gas discharge-semiconductor system in nitrogen: Effect of fluid modelling approach Rafatov, İsmail; Yeşil, Cihan (2018-08-01) A laterally extended dc-driven system of planar gas discharge with a high-ohmic semiconductor electrode is considered. Numerical models are based on the fluid equations of plasma with drift-diffusion approximation for particle fluxes. The effect of different modelling approaches (with simpler and more detailed treatment of the electron transport and plasma chemical reactions) is analyzed. Bifurcation diagrams separating stable stationary states of the system from oscillatory states are derived and compared ...
