Synthesis of Nanomaterials by the Pulsed Plasma in Liquid and their Bio-medical Applications

Emil ÖMÜRZAK | Ruslan ADİL AKAY TEGİN

Pulsed plasma in liquid is a simple, ecologically friendly, cost-efficient method based on electrical discharge between two metal electrodes submerged into a dielectric liquid. We synthesized carbon-encapsulated Fe (Fe@C) magnetic nanoparticles with low cytotoxicity using pulsed plasma in a liquid. Body-centered cubic Fe core nanoparticles showed good crystalline structures with an average size between 20 and 30 nm were encapsulated in onion-like carbon coatings with a thickness of 2–10 nm. Thermal gravimetric analysis showed a high stability of the as-synthesized samples under thermal treatme ...More

Copper Nanoparticles: Synthesis and Biological Activity

Emil ÖMÜRZAK | Tinatin DOOLOTKELDİEVA | Saykal BOBUŞOVA

By means of XRD and FESEM analysis, it is established that copper nanoparticles with sizes less than 10 nm are formed during the chemical reduction, which form aggregates mainly with spherical shape. Presence of gelatin during the chemical reduction of copper induced formation of smaller size distribution nanoparticles than that of nanoparticles synthesized without gelatin and it can be related to formation of protective layer. Synthesized Cu nano-powders have sufficiently high activity against the Erwinia amylovora bacterium, and the bacterial growth inhibition depends on the Cu nanoparticles ...More

Synthesis of biologically active silver and copper nanocomposites

Tinatin DOOLOTKELDİEVA | Emil ÖMÜRZAK

In the joint chemical reduction of silver and copper ions in the presence of gelatin, regardless of the composition of the reaction medium, a nanocomposite was formed consisting of nanodispersed silver and copper particles. In this research, the dependence of phase composition and dispersity on the synthesis conditions, as well as antibacterial activity of synthesized silver and copper nanocomposites were studied. It has been established that the most highly dispersed silver and copper nanocomposites were formed in an alkaline medium. We have revealed that nanocomposites of Ag-Cu system which ...More
