The College of Engineering at the University of Baghdad held the public defense of master’s student Hassan Mohammed Ibrahim<\/strong> from the Department of Energy Engineering<\/strong> on Thursday, June 19, 2025<\/strong>, in the Petroleum Engineering Hall, for his thesis titled:
\n\u201cPreparation and Analysis of the Effect of Partial Substitution of Cadmium Nanoparticles on the Structural, Electrical, and Dielectric Properties of the Superconductor Pb\u2082\u208b\u2093Cd\u2093Ba\u2082Ca\u2082Cu\u2083O\u2081\u2080.\u201d<\/em>
\nThe thesis was supervised by Asst. Prof. Dr. Moayad Khalil Ibrahim<\/strong> and Prof. Dr. Kareem Ali Jassim<\/strong>.<\/p>\n

The study focused on examining the structural, superconducting, and dielectric properties<\/strong> of the compound Pb\u2082\u208b\u2093Cd\u2093Ba\u2082Ca\u2082Cu\u2083O\u2081\u2080<\/em>, synthesized via the solid-state reaction method. The primary goal was to understand the impact of cadmium substitution on the material’s characteristics.<\/p>\n

The results indicated that cadmium improves the compound’s properties at a concentration of x = 0.1<\/strong>, where the highest critical temperature (Tc = 148 K<\/strong>) and best phase purity (82.48%<\/strong>) were achieved. X-ray diffraction (XRD) and Atomic Force Microscopy (AFM) analyses showed enhancements in the crystalline structure and magnetic flux pinning at this concentration. However, increasing the cadmium concentration beyond x > 0.1<\/strong> led to a deterioration in properties due to lattice contraction and the formation of secondary phases.<\/p>\n

These findings suggest that x = 0.1<\/strong> is the optimal concentration to achieve a balance between crystal structure and electronic performance, offering valuable insights for designing more efficient superconducting materials.<\/p>\n

Based on the study\u2019s findings, the researcher made the following recommendations:<\/p>\n

    \n
  1. Synthesize and test the optimal compound (x = 0.1<\/strong>) in larger quantities for a comprehensive evaluation of its properties.<\/li>\n
  2. Explore potential applications of the compound in emerging fields such as sensors<\/strong> and energy storage devices<\/strong>.<\/li>\n
  3. Assess the economic feasibility<\/strong> of large-scale industrial production to support the broader use of such materials in Iraq.<\/li>\n<\/ol>\n

    Following a detailed public discussion by the committee members and after evaluating the student\u2019s defense and the quality of the research, the examining committee awarded the student a Master\u2019s degree in Energy Engineering with a grade of \u201cExcellent.\u201d<\/strong>[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column][vc_gallery interval=”3″ images=”8513″ img_size=”large” css=””][\/vc_column][\/vc_row]<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"
