The head of Materials Engineering Departments obtain a patent

The head Materials Eng. Dep. at UOT, Assist. Prof. Dr. Hussein Alaa Jaber obtained a patent titled (Synthesis of nano-sized substituted hydroxyapatite by using rare earth elements, magnesium, and zinc for bio-applications). The patent included creation of a new bio-material, which is hydroxyapatite compensated for with rare earth elements, magnesium and zinc, prepared in nano-size through wet chemical precipitation method, where 5% of the calcium ions in the hydroxyapatite were replaced by neodymium, cerium, magnesium and zinc ions. Numerous tests were carried out to characterize the prepared materials, and the biological properties were evaluated by examining the resistance of the substituted hydroxyapatite to bacteria and fungi, in addition to testing the effect of the substance on normal cells and bone cancer cells. The results showed a new structure of hydroxyapatite after the replacement process and a significant improvement in the material's resistance to bacteria and fungi and bone cancer cells compared to the original material before the replacement process.
