The lecturer from the Department of Physics (Lect. Haider Fahim Saber) obtained a doctorate for his thesis entitled (Study of the phenomenon of the Permian transition in some iron-based compounds using electron Permian resonance techniques) from the Department of Physics / College of Science / University of Basra. The aim of the thesis was to explain how temperature affects the phenomenon of Permian transition, considering temperature as a foreign catalyst that modifies what is observed under coordination complexes, especially for iron fines, studying thermally induced transformations of solid matter between high-permian and low-permian states in Permian transition systems, and looking at thermodynamics. It also addressed the practical aspect of studying nanomolecular layers of iron 1,10-phenanthroline: This study uses the structure of iron 1,10-phenanthroline as a probe to prepare molecular nanolayers. The study included the study of iron-based compounds and the study recommended: This field includes multiple elements and future applications, including surface modification, spectroscopy, modeling, device testing, biomedical uses, and environmental applications, all aimed at enhancing efficiency and effectiveness. The thesis recommended that this process is complex and characterized by several methods, including: (electron spin resonance), (vibrating sample magnetometer), ultraviolet spectrophotometer, photodetector evaluation, (energy dispersion spectroscopy), and X-ray diffraction. Field emission scanning electron microscopy, Raman, and infrared scanning are some of the methods used here that aim to gain a better understanding and appreciation.
