The Construction and Projects Department is completing the construction of a bridge linking the two buildings of computer science

The Construction and Projects Department at the University of Technology has completed construction work of a bridge linking the two buildings of the Department of Computer Science in a style consistent with the facade of the two buildings coated with stone, which gives an aesthetic in the unification of packaging materials between the past and the present.

The bridge consists of a metal structure installed with four main pillars and a casting floor coated with plastic rugs and plastic panels for the walls as it contains six windows for the purpose of lighting and ventilation as well as external packaging with (sandwich panel) and final packaging with a Styrofoam stone style in order to impart an architectural style that is consistent with the requirements Structural and urban era.

The student, Shanaz H.Ahmed, obtained a master’s degree for her thesis entitled "Preparation of nanocomposite polymers as building materials" in the field of materials science.

The discussion committee consisted of Dr. Waham M. Hamid, chairman of the committee, Dr. Hana J. Kazem, Ban A. Youssef, as members and Dr. Rana M. Salih as supervisor.

 This work aims to enhance acoustic and thermal insulation properties for polymeric composite by adding nanoclay and rock wool as reinforcement materials with different ratios.  A polymer blend of (epoxy+ polyester) as matrix materials was used, and hand lay-up technique was used to manufacture the castings. Epoxy and polyester were mixed in different weight ratios (50:50, 60:40, 70:30, 80:20, and 90:10) wt. % of (epoxy: polyester) respectively. The optimum mixing ratio (OMR) was decided upon the highest value of impact test carried out on the blends of the above mentioned ratios, which showed that the (80:20)wt.% epoxy: polyester respectively had the highest impact strength value, hence was selected as a matrix for the composite.Nano clay (Kaolinite) with ratios (5 and 7.5% ) wt.% , also hybrid reinforcement materials involving (Kaolite 5 & 7.5 % wt.% + 10% volume fraction of rockwool ) were added as reinforcement materials to the optimum sample.

The results show that the addition of nanoclay in a percentage of 7.5 wt.% Leads to the highest sound insulation, such that the sound intensity for low frequencies was 99.8 dB, reaching to 101 dB at high frequencies (10000 Hz), suggesting much lower values than the unreinforced blend, of which the sound intensity started from 107.2 dB to 108.7 for the same range of frequencies.

Thermal conductivity results showed that the composite with 7.5 % wt. has the lowest value (about 0.443 W/m.°C). The result of water Absorption showed that the diffusivity varied according to the type of material and its temperature. Mechanical properties (bending behavior, compressive strength, impact strength and flexural strength) were studied for these specimens. The results showed that the blend reinforced with nano clay in a weight fraction 7.5% and hybridized with rockwool volume fraction 10% had the lowest deflection and the highest value of Young’s modulus (1889.49)MPa in bending, while blend reinforced with 5%wt. nanoclay and 10%vol. rockwoolshowed the highest value of compressive strength (396.95) MPa. The reinforcement with nanoclay reduced the impact strength, such that the lowest impact strength was 0.0055KJ/m² for (blend+5% nanoclay). The results of flexural test showed that the (polyester+ epoxy) blend have the highest value of flexural strength(57.4MPa). The reinforcement with 5%wt. fraction of nanoclay and 10%vol. fraction of rockwool have led to a reduction in flexural strength to the lowest value, which was 16.53 MPa.

The Department of Laser Engineering awards a master's degree in hybrid polymers to a nanoscale superposition of high refractive index contact lenses

The Department of Laser and Optical Electronics Engineering at the University of Technology awarded the master's degree to the student Lina Mohamed Shaker on her tagged message (Hybrid polymers of nanocomposite for high refractive index contact lenses).

The results showed that (PMMA-Tio₂) is the best material for the manufacture of contact lenses and the effect of deformation was verified by using nanoparticles. The highest refractive index and the best Abi number were obtained with a concentration of 01.0 w / v. All evaluation criteria showed that eye vision improved with the use of the lens Concentration of 01,0 w / v The highest contrast was obtained in the MTF function, the highest inclination value in the aggregated power scheme, the smallest spot size, and the best clarity of the image formed on the grid.

The Department of Petroleum Technology hosted a meeting of the Committee of Experts chaired by Prof. Ali Mohsen Al-Mashat and in the presence of the head of the department Prof. Dr. Fadhel Sarhan Kazim and Head of the Department of Petroleum Engineering / Baghdad University Prof. Dr. Faleh Al-Mahdawi and Dr. Ahmed Khalil and the scientific assistant of the Department Dr. Najem Abdel-Kazim, Prof. Ahmed Abdullah Ramadan and Prof. Ramzi Sihoud, on 5/1/2020, in the Hall of the Department Council.

The meeting discussed the completion of the system of scientific decisions in the department and consideration of the agenda sent by the Ministry of Higher Education and Scientific Research to the committee.

The Department of Petroleum Technology held a workshop for engineers and technicians entitled (General Geology) delivered by the teacher, Dr. Hussein Elibi Zamil, on Tuesday 7/1/2020 at the Geology Laboratory. The workshop aimed to introduce the engineering cadre to the basic principles of synthetic physical geology and the importance of identifying the vocabulary of this specialization that is closely related to the engineering side and specifically the engineering of oil technology, especially geology and oil reservoirs and drilling operations of wells and reservoir pressures and the difficulties they face in terms of hardness and quality of rocks and the type of hydrocarbons and traps Petroleum scattered in large areas of Iraq, as the engineering cadre was defined by physical and chemical factors that affect the processes of formation of the Earth's crust and its fiery and sedimentary rocks as well as a study of Metals in
