As part of its ongoing research activities aimed at fostering scientific innovation, the Department of Physics at the College of Science conducted the comprehensive doctoral examinations, during which PhD candidates presented distinguished scientific research addressing the development of advanced materials and their applications in the fields of "energy and optics.
First Project: Hybrid Materials for Advanced Optical Applications**

PhD candidate "Hind Hamed" delivered a research presentation as part of her comprehensive examination entitled: “Synthesis of Hybrid Particles Based on Calcium Titanate: A Spectroscopic and Computational Study as a Promising Material for Optical Applications.”
The examination committee was chaired by Prof. Dr. Ahmed Salman Obaid, with the membership of Assist. Prof. Dr. Sattar Salim Ibrahim, Assist. Prof. Dr. Moayad Mahmoud Mutlak, and **Asst. Prof. Dr. Auras Abdulhadi Hussein.
The research was supervised by Prof. Dr. Adel Naama Ayash and Prof. Dr. Omar Hamad Shehab.

The project aims to synthesize and investigate hybrid particles based on **calcium titanate (CaTiO?) through integration with optically active metal oxides, specifically **titanium dioxide (TiO?) or **tungsten trioxide (WO?). The study seeks to develop new hybrid systems with enhanced optical and electronic properties, supported by precise spectroscopic analyses and experimental and computational calculations, with the ultimate goal of exploiting the results in future **photonic applications*.

Second Project: Nanotechnology for the Development of Metal-Ion Batteries

In a related energy-focused context, PhD candidate "Sarah Ali Abdul Karim" presented her research entitled: “Synthesis of Polymer–GaN Nanofibers via Electrospinning for Battery Anodes: A Systematic Study of Deposition Parameter Effects.”
The examination committee was chaired by Prof. Dr. Jamal Malallah Razeeg**, with members Assist. Prof. Dr. Hatem Abdul Razzaq Taha, Assist. Prof. Dr. Alaa Ahmed Dayeh, and Assist. Prof. Dr. Jamal Fadel Mohammed.
The research was supervised by Prof. Dr. Ismat Ramzi Abdul Ghafoor and Assist. Prof. Dr. Yusra Mahmoud Hamadi.

This study focused on fabricating composite nanofibers containing gallium nitride (GaN) nanoparticles embedded within a polymer matrix using the electrospinning technique, ensuring uniform distribution of the active material. The research aimed to assemble enhanced battery cells using GaN/CNF composites as anode materials and to evaluate their electrochemical performance. The results demonstrated that optimal voltage, low flow rates, and moderate deposition distances contributed to the production of uniform, fine nanofibers with high deposition efficiency.
These research projects reaffirm the University of Anbar’s commitment to rigorous scientific research and to linking academic output with practical applications in the fields of technology and renewable energy.
