Argon and nitrogen plasma modified polypropylene: Surface characterization along with the optical emission results MANSUROĞLU, DOĞAN; Uzun Kaymak, İlker Ümit (Elsevier BV, 2019-01-25) This study focuses on the surface modifications of polypropylene using a capacitively coupled radio frequency gas discharge system. Improvements on the polymer surface properties are investigated for the case of argon and ...
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 mod...
Investigation into Ex-Situ and In-Situ Iodine Doped Plasma Polymerized Fluorene-type Thin Films Mansuroglu, Dogan; Uzun Kaymak, İlker Ümit (2019-01-01) Effect of doping is investigated by applying iodine dopant to plasma polymerized fluorene (C13H10)-type thin films utilizing two separate techniques: ex-situ and in-situ doping. In this study, the thin films are produced u...
Characterization of high microwave power atmospheric pressure plasma torch TÜRKYILMAZ, BAHADIR; MANSUROĞLU, DOĞAN; Uzun Kaymak, İlker Ümit (Canadian Science Publishing, 2018-07-01) An atmospheric pressure microwave plasma torch operating at 2.45 GHz frequency using a surfaguide waveguide fed by argon gas at a constant rate is characterized at various microwave power settings. Coarse optical emission ...
A study on changes in crystallization of plasma modified polypropylene Mecit, Giray; Mansuroğlu, Doğan; Uzun Kaymak, İlker Ümit (2017-09-19)
Enhancement of electrical conductivity of plasma polymerized fluorene-type thin film under iodine and chlorine dopants MANSUROGLU, Dogan; Uzun Kaymak, İlker Ümit (2017-08-31) Electrical and optical properties of plasma-polymerized fluorene-type (C13H10) iodine-and chlorine-doped thin films are investigated. Fluorene-type thin films are produced using a mixture of biphenyl (C12H10) and methane (...
An experimental approach to period doubling bifurcations in plasmas Uzun Kaymak, İlker Ümit (2017-01-01) Summary form only given. A direct current (dc) driven semiconductor-gas discharge system is designed to study nonlinear behavior and period doubling features experimentally. Numerical analysis and theoretical studies show ...
SURFACE MODIFICATION OF PET, PS, PE POLYMERS BY SINGLE RF PLASMA DISCHARGE Mansuroglu, Dogan; Uzun Kaymak, İlker Ümit (2017-01-01)
Investigation of Planar Barrier Discharges for Coherent Nonlinear Structures Uzun Kaymak, İlker Ümit (2016-09-09) Nonlinear pattern formations are ubiquitous in nature. One of the analogous configurations in laboratory experiments to such nonlinear systems is the current filament formations observed in glow plasmas. These filaments ca...
Detection of far-infrared radiation using glow discharge detectors Takan, TAYLAN; ALASGARZADE, Namig; Uzun Kaymak, İlker Ümit; Sahin, Asaf B.; Altan, Hakan (2016-05-01) The plasma medium, created inside the neon indicator lamp, enables the detection of a wide wavelength range of differential or modulated EM signals. The interaction between the plasma and various frequency EM waves are sti...
