Activated carbon obtained from the cotton processing wastes

Külümkan SARTOVA | Emil ÖMÜRZAK | Bakıt BORKOYEV

Activated carbon (AC) was obtained from the cotton (Gossypium malvaceae) processing waste materials. The process was carried out by carbonization at 500–800 °C and subsequent activation at 800 °C by water stream. Cotton biomass is a renewable, low-cost alternative source for textile and food products; however, it hasn't been used for manufacturing of an activated carbon by carbonization in a boiling layer method. Characterization of adsorbents by means of Scanning Electronic Microscope and FT-IR showed that high porosity of carbonized products which was achieved and functional groups were form ...Более

Preparation of stabilized silver and tin nanocomposites by electrical discharge

Emil ÖMÜRZAK

In this study silver and tin nanocomposites were synthesized by electro spark dispersion in ethanol. Resulting nanocomposite was characterized by using the powder x-ray diffraction and emission scanning electron microscopy. It was found by X-ray phase analysis that the product obtained by electro spark joint dispersion of silver and tin in ethanol consists of two phases: Ag3Sn and beta-Sn. The results of processing SEM micrographs of the product of the Ag-Sn system show that the obtained phases are spherical nanostructures with sizes of 30-60 nm. This size of nanostructures was associated wit ...Более

Effect of surfactant materials to nanoparticles formation under pulsed plasma conditions and their antibacterial properties

Emil ÖMÜRZAK | Ruslan ADİL AKAY TEGİN

Pulsed plasma between two Zn rods submerged into aqueous solution of cetyl trimethylammonium bromide (CTAB) and sodium dodecyl sulphate (SDS) surfactants resulted in formation of pure ZnO nanorods, while the pulsed plasma between two Zn rods in water without surfactant yielded a mixture of ZnO and Zn nanoparticles. Carbon coated ZnO nanorods with about 20 nm thickness and 150 nm length were synthesized by this method using different surfactant materials such as CTAB and SDS. Cu nanoparticles of about 10 nm in size were also synthesized by the pulsed plasma in aqueous solution of 0.2 % gelatine ...Более
