Abstract:

In this research, thin films were prepared for nanocomposite materials deposited on quartz substrates by the pulsed laser deposition (PLD) method. The percentage of copper in the target material (3, 5 and 7%), the laser energy (600, 700 and 800 MJ) and the substrate temperature were used. (200, 300 and 400 Cᵒ) as variables for this technique. The design of experiments (DOE) using Taguchi was used, which designed (27) experiments according to these three factors. The prepared films were examined using (XRD, AFM, FESEM, EDX, Uv-Vis, Nanoindentation) to know The structural, optical and mechanical properties of the prepared thin film films and the knowledge of the optimum thin film using (Composite Desirability), which works towards increasing the hardness and reducing both the energy gap and the  surface roughness and it was (11.23 Gpa, 2.79 ev and  1.25 nm) respectively , and (ANOVA) analysis showed that the most influential factor was In the results, the value is the percentage of copper in the target material..

The discussion of the dissertation was conducted in a scientific atmosphere and a master's degree with grade of pass was awarded to the student after the completion of all the corrections that have been decided by the examiners.

The Department of Materials Engineering / University of Technology, under the patronage of the President of the University of Technology, Dr. Prof. Ahmed Mohamed Hassan Al-Ghabban, and with the supervision of the head of the Materials Engineering Department, Asst.

The symposium included a number of lectures:

- The first lecture: by Asst. Prof. Dr. Muhammad Rumeid Gharkan and lecturer  Hashem Sharif Al-Jazaery)/University of Technology/Department of Materials Engineering/ Title of the lecture: "Technical Guidelines for Fire Hazards for Sandwich  Panels"

- Second lecture: Lt. Colonel Raed Hokan / General Directorate of Civil Defense / Title of the lecture
"The Hazards   of Using Insulating Panels"

- Third lecture: Asst.Prof.Dr. Muhammad Abdul-Hussein Al-Zuhairi/University of Technology/Department of Materials Engineering/The title of the lecture is "Sustainability of sandwich panels in Iraq between reality and the future"

The symposium aimed at diagnosing the problem of using sandwich panels in construction, and searching for immediate and future solutions to manage fire risks when using such materials, while addressing the incorrect uses of them and the resulting damage to come up with recommendations and appropriate implementation solutions, with the necessity of activating them when using them. Sandwich panels in various construction operations. At the end of the seminar, certificates of appreciation were distributed to the guests and lecturers.

The Department of Materials Engineering at the University of Technology awarded a doctoral’s degree to Alaa Sabeeh Tayeh,, Department of Materials Engineering/ University of Technology, for his tagged dissertation (Fabrication of Advanced Ceramics Materials for Medical Applications"

Where the discussion took place in the postgraduate hall in Building B in the department on Thursday, 08/09/2022 at nine in the morning, and the discussion committee consisted of:

Abstract

The advanced ceramic ZTA (biolox) is used in artificial joints. ZTA (biolox) was synthesized and modified by using (0.25, 0.5, 0.75, and 1) wt. % of CaF2 and MgO. The sol-gel technique was utilized to make a nanocomposite powder using aluminum, zirconium, strontium, and chromium salts. The characterization, physical, mechanical, and biological properties were studied. The results show that CaF2 improved the mechanical properties of ZTA except for hardness, which decreased with increasing CaF2 concentration from ~16.84 to 14.50 GPa. However, MgO has two effects on ZTA properties depending on its concentration: below 0.75 wt.%, the effect enhances ZTA properties, but above this concentration, the effect reverses and causes a significant reduction in properties.

The discussion of the dissertation was conducted in a scientific atmosphere and a master's degree with grade of pass was awarded to the student after the completion of all the corrections that have been decided by the examiners.

Abstract

The aim of this study is to evaluate the possibility of using waste rubber tires as a substitute for sand and gravel. The physical and mechanical properties of rubber concrete have been tested for various sizes of rubber chopped by proportions different, so the properties that rubber concrete can gain by using this alternative are low cost, lightweight, toughness, shock absorption, and heat insulation, and preserving the environment by providing a safe solution.

The discussion of the dissertation was conducted in a scientific atmosphere and a master's degree with grade of pass was awarded to the student after the completion of all the corrections that have been decided by the examiners.
