Doctoral thesis discussion in the Department of Physics, Faculty of Education, Al-Qadisiya University, titled (Preparation of Nanoparticles Using PLA Technology and Descriptions in Medical Applications) by Zahra Sahib Shanon and supervised by Asst. prof. Dr. Mushtaq Talib Jassim<\/p>\n
The aim of the dissertation is to present an innovative methodology in the synthesis of nanoparticles, and this study is the first of its kind that uses the pulsed laser ablation technique in liquids (PLAL) to prepare a trimetallic system and a system of metal oxides in the core-shell structure, overcoming the shortcomings of traditional chemical methods.<\/p>\n
The main conclusions in this study are the successful acquisition of the “Core-Shell” structure of two innovative trimetallic systems (Au@Ag@Pd) and (Pd@TiO\u2082@SiO\u2082) with oxides, through the technique Ablation with pulsed liquid laser (PLAL) at a wavelength of 532 nm, and confirming this structure and physical properties using (TEM), (XRD), (EDX) and (UV-Vis) techniques, and proving high stability through zita potential measurements<\/p>\n
Important recommendations Based on these results, more studies can be conducted on the study of the effect of magnetic field application on the properties of nanoparticles during pulsed laser ablation. When studying the effect of trimetallic nanoparticles on normal human skin cell lines (NHF), a killing rate of 53% was observed at the highest concentration.<\/p>\n","protected":false},"excerpt":{"rendered":"
