Dr. Fadhel Attia Jeyad and prof. from the Department of Materials Engineering at the University of Technology. Akram Rahim Gabr and  Sabreen Ali Abd Ali patent entitled:

"Fabrication and classification of functionally functional nanotubes of nanoparticles using prepared nanoparticles"

The patent included the preparation of barium nanotubes and ferrite nanotubes using the liquid gel method to manufacture functionally graded polymer materials where the hardness varied with the change of component properties as well as the fundamental heterogeneity in the microscopic structure and magnetic properties. The electrical properties of the ellipse were affected although the thickness of the solid samples prepared was small This makes nanoparticle materials efficient for use in transformer applications, microwaves, as well as electronic applications.
