Plasma modification of PMMA films: surface free energy and cell-attachment studies
Ozcan, Canturk; Hasırcı, Nesrin (2007-06-01)
The surface of a material is the most important part determining the acceptance by and compatibility with the environment. In many cases, although the bulk properties are excellent for a specific application, the surface may require to be modified and engineered in the desired direction. This is especially important for materials used in biological media, since the surface charge, hydophilicity and wettability are important for thrombosis formation, cell attachment or cell proliferation. In this study, poly...
Plasma-Induced, Solid-State Polymerization of N-Isopropylacrylamide
Unver, Alper; Akovali, Guneri (Wiley, 2010-03-15)
The radio-frequency plasma-initiated polymerization of N-isopropylacrylamide (NIPAM) in the solid state was performed. The isolated linear polymer was characterized by C-13-NMR, H-1-NMR, and Fourier transform infrared spectroscopy, and the effects of selected operational plasma parameters (discharge power and time) on the conversion rates were studied. Reversible transitions at the volume-phase-transition temperatures of the swelled poly(N-isopropylacrylamide) hydrogels were investigated by differential sca...
Plasma polymerization of selected organic compounds
Dilsiz, N; Akovali, G (1996-01-01)
Plasma polymerization reactions and plasma polymers of xylene/air, xylene/argon, xylene/air/argon, toluene/air/argon, dioxane and allyl cyanide were compared with respect to discharge power (between 50 and 500 W), where all other plasma operational parameters were kept constant. In plasma polymerization, the glow characteristics are known to play an important role depending on the factor W/F,where W is the discharge power and Fis the monomer flow rate. In plasma polymerization reactions, it is known that de...
Plasma Synthesis of AlNiCo Core/Shell Nanopowders
Genç, Ayşe Merve; Öztürk, Tayfur; Kalay, Yunus Eren (2018-11-26)
Aluminum-nickel-cobalt (AlNiCo) permanent magnets revolutionized the permanent magnet industry in 1920’s but has not been thoroughly studied after the development of powerful rare-earth permanent magnets. As compared to rare-earth magnets, AlNiCo magnets have high remanent force (Br), better corrosion resistance and higher Curie temperature but lack high coercivity. If the coercivity is improved, BHmax value may increase up to values that would potentially fill the gap in between rare-earth and rare-earth f...
Plasma Generation in a Gas Discharge System With Irradiated Porous Zeolite
Ozturk, Sevgul; Ozner, Metin; Bulur, Enver; Salamov, Bahtiyar G. (2015-06-01)
The influence of pressure [from atmospheric pressure (AP) to 10(-2) torr] and beta-radiation (1-kGy beta doses) on the current-voltage characteristics, charge trapping effects in porous surfaces, and breakdown voltage (UB) in AP microplasmas are discussed for the first time. This is due to the zeolite cathode (ZC) exposure to beta-radiation resulting in substantial decreases in the UB, discharge currents, and conductivity due to increase in porosity of the material. Results indicated the enhancement of plas...
