The public discussion of the master's student (Safaa Mahmood Atallah) Department of Chemistry - College of Science - University of Anbar took place on Monday 11/28/2022 in Jaber Bin Hayyan Hall in the College of Science for his thesis tagged:

((Preparation of saline Nano composites and utilize in improving the thermal decomposition products of polymeric wastes)).

The aim of the study is to prepare nickel oxide and Barium Oxide Nanoparticles by using cold plasma technology, and then use the resulting nanoparticles in the preparation of saline Nano composites with different concentrations of nickel oxide and Barium Oxide Nanoparticles with 3 gram of sodium chloride salt. The resulting nanoparticles in different concentrations are used to improve the thermal decomposition products of polypropylene and polystyrene polymers by simple distillation, and better results were obtained with polypropylene, especially when using a nickel oxide nanocomposite at a concentration of 50.6 ppm, and the results obtained at 280 °C were better than distillation at 350 °C.
