On 19/11/ 2017 Master thesis of the student Amna Jalal Sadek which titled,

“ Manufacture of new polymeric membranes for waste water treatment”,

 has been discussed and the members of discussion’s committee are listed below

The letter included the use of PVC polyvinyl chloride with the addition of a modified mixture of Graphene oxide and multi carbon nano tube MWCNTs-g-GO using phase inversion. Four polyvinyl chloride membranes were manufactured with the addition of MWCNTs-g-GO at different rates (0,0. 006, 0.12, 0.22). Two polyvinyl chloride  were also fabricated by addition  0.12 (GO, MWCNTs).

It was confirmed that the activation of the acidity of MWCNTs-g-GO, GO and MWCNTs was successful by using the necessary tests. The results showed the appearance of effective groups and interaction between the carbine oxide and the MWCNTs-g-GO.

This thesis had been scientific evaluation by Assistance Prof Dr. Saad Hanash Ammar, Nahrain University, Faculty of Engineering, Department of Chemical Engineering and linguistically by Prof Dr. Arkan Khalkhal Hussein / University of Technology/ Mechanical Department. The discussion of the thesis had been performed at the Fadul Attya hall, and the discussion’s committee agreed to award the student master degree.

Master thesis of Aynoor Ibrahim Alijan, who is one of high studies student in department of materials engineering, which titled “green concrete property by using recycled materials” had been discussed

Discussion committee members was as listed below

The thesis studied using: tiles’ powder, lamps’ glass, gray glass powder, rice peel ash, and two types of wood powder, as partial cement replacement. Various weight fractions,(11,13,15) % had been used with basic plain concrete ,which had (3/1.5/1) mixture (fine aggregate/cement/water), and (0.45) water/cement, with different curing times, (7, 14, 28) days. According to the replacement materials that used 19 categories of specimens included basic mixture concrete (plain concrete) had been prepared with grain size of all mixtures’ ingredients range (75-600) µm. the work’s results show that only few replacement types of those used as partially cement replacement can improve mechanical properties of concrete.

The discussion of the thesis had been performed at the Fadul Attya hall, and the discussion’s committee agreed to award the student master degree.

The Iraqi Journal of Mechanical Engineering and Materials in Issue No. 2, Vol. 17 of 2017, published two research papers on materials engineering, the University of Technology. Assist. Prof. Dr. Akram Rahim Jabr.

The first research (synthetic and magnetic properties of nickel-ferrite nanoparticles) dealt with the microscopic structure of the fiber produced by the electrospine method for solution polymer (PVP) by addition to nickel nitrate and iron nitrate to formation of fiberglass nanometers nickel-ferrite, which were studied using electronic microscopes SEM and X-ray examination and proved a phase transformation from random to syntactic depending on the temperature of the burn as well as the magnetic flux measured by the magnetic vibration scale.

The second research (Nanocomposite membrane from Titanium Dioxide - Nylon 6 to improve the discharge of salts under low pressure for water filtration of nanotubes) . Study the procedure of the electrospine  Nylon 6 with nano-titanium oxide. The membrane had a nanoscale network with a radius of 123 nm and the properties of the contact angle, wetting, mechanical tensile, water purification, antibacterial and salt repellant were improved.

On 14/11/ 2017 Master thesis of the student Shahd Abdul Azem for her thesis titled,

“Effect of reinforcing rod of reinforced polymer by glass fiber on the properties of Portland cement)”,

 has been discussed and the members of discussion’s committee are listed below

The thesis study use of polymer reinforced by fiber as an alternative to reinforcing steel. reinforcing rod are manufactured by using long glass fibers (reinforced material) and unsaturated polyesters (base material) with 1% methyl acetone peroxide by a manual process similar to continuous molding. . Reinforcing rod of the composite material with a diameter of 12.5 mm, which is equivalent to half of inch, which is more common in construction applications after many attempts of using different types of glass fiber. The surface finish of the reinforcing rod of the composite material was two types (smooth and the other rough by sand treatment to increase bond strength between reinforcing material and concrete). The results showed that the tensile strength of the composite material was high and the bending properties were acceptable at the expense of the bending coefficient. Compression strength was within a close range of all concrete samples, this is due to the fact that the concrete itself shows high compressive strength as well as reinforced concrete with coarse sand-coated material rod showing high compression resistance due to increased compression coefficient. The bending resistance of the un-reinforcing concrete is low and the reinforced concrete with the reinforcement rod of the coarse sand graded material shows a significant improvement in bending resistance as a result of increased bonding with the concrete and higher interaction from iron-reinforced concrete at the expense of bending coefficient.
