Publication of Assist Prof. Dr. Akram Rahim Jaber teaching in the Department of Materials Engineering / Technology University three researches included:
1. Joind research is marked by: Infrastructure and properties of Fright fiber nickel nanoparticles by electric spinning technique
Which was published in the Journal of Advanced Applied Science in 06/02/2016 which included the preparation of Fright fiber nickel nanoparticles at different ratios by using Zinc nitrate hexahydrate, nickel Hydrate Fright, Nonahydride iron nitrate, polyvinyl pyrrolidine and Dimethylformamide. This has been used as materials operational. The crystalline behavior studied of these materials by X-ray powder diffraction (XRD) - Which led to the change of phases nanoparticles from random to frate twirling by depending on the degree of calcination temperature at a temperature of 700 Celsius. Crystal size was calculated by a Shearer formula by 23.75 nm.
2. Joind research is marked by: Fabrication and characterization of polymer electrical conductive from nylon 6 / multi wall carbon nanotubes by electric spinning technique
Which was published in the International Journal of Thin Films Science and Technology on 13.3.2016 , the research included calculation of Electrical conductivity of pure liquid polymer to Nylon 6 and a ratio was obtained of 33.8 × 10-3S / cm, while this percentage increased with the addition of carbon nano-tubes of the liquid polymer, , also the research included the examination of structural membranes prepared by scanning electron microscope (SEM) and calculated the average fiber diameter of nanoparticles and found equal to 140 nm, and increased electrical conductivity of the membranes prepared from pure nylon.
3. Joind research (Assist Prof. Dr. Akram Rahim Jaber, Assist Prof. Dr. Laith Kais Abbas) is marked: Effect of high voltages and data flow velocity on preparation of diameter nanotube by electric spinning technique
Which was published in the Journal of physical sciences and applications in 2016 and the research included use of electric spinning technique to prepare scaffold tissue simulate, biologic polymers, industrial and natural to be used in tissue engineering applications, fluids were prepared from polyvinyl alcohol PVA as biological polymer to manufacture scaffold by electric spinning technique to emulate the ideal shape and size of the fiber spun by changing operational conditions for spinning electric and shedding high voltage of 5-25 kV and a flow rate of the liquid polymer from 0.1 to 10 ml / hr.

In this research nano-powders was prepared from oxide ceramic by chemical-thermal spray technology. Have been manufacturing metal unilateral and bilateral oxides from base metal salts which dissolved in water CuSO4 and Ti (SO4) 2 (for the production of titanium oxide) TiO2 (copper oxide) CuO respectively at a spray temperature reached (700 ± 5 ° C) in different mularriet ( 0.10, 1.0 and 1 mol ). The nanoparticle powders were produced used as an additive material for cement mortar in different ratio weight (5.0, 5.2, 5 and 5.7% ) for use in construction applications including buildings packaging.
The results showed that the nanoparticles prepared powders have size granules (7. 55 nm) for titanium oxide and (8.67 nm) for copper oxide with crystalline structures and systems of Tetragonal and Monoclinic respectively. Since the bulk density has increased and thermal conductivity decreased with increase the ratio of nanoparticles powders added and prepared cement mortar has been improved with adding powders of nanoparticles which makes them useful in future applications, especially modern construction applications
5- Joined research was published marked: mechanical and physical properties of carbon nano-tubes with Kevlar fiber reinforced with resin Polyester by teaching (Assist Prof. Dr. Aseel Basem Abdul-Hussein, Assist Prof. Dr. Imad Abdul-Karim Saadi, Marwa Sobhi Atallah) / Department of Materials Engineering in the Iraqi Journal of Physics on 12/2016
In this research it has been studied hardness (Shore D), water absorbency, Fracture strength testing, Impact test and Durability of Fracture at Nano- composites with the basis of polyester unsaturated resin reinforced Kevlar fiber. Samples processed in a manual casting way according to the base of the mixing of different size fractions from polyester unsaturated resin, fiber and carbon nano tube (1, 1.5, 2.0 %). Polyester unsaturated resin was ground reinforced with 3% volume fractions from Kevlar fiber and (0.5 %) carbon nano tube. The study of the properties of water absorbency, hardness (Shore D) and fracture strength. Results showed that the absorbency of water increases with increases volume fractions for fiber with carbon nanotubes , sample (poly ester + 3% fiber Kevlar + 0.5% carbon nanotubes) has a lower absorbency of water. Fracture test, impact test, Hardness test and durability fraction of the sample (poly ester + 3% fiber Kevlar + 0.5% carbon nano-tubes) has the highest value for the composites of nanoparticles.
