The growing global economy resulted in an incessant increase in transportation and exploitation of oil. Hence, the oil spillage has been considered a serious threat to aquatic and terrestrial ecosystems. Therefore, water purification has been considered a major challenge around the world. There are numerous classical methods available for oil remov...

The interest in solar energy applications doubles due to the necessities of the stage, and because of it, the interest in heat storage materials expands, the most important of which is paraffins. Paraffins suffer from low thermal conductivity, so many researchers have added nanomaterials that improve this property. In this study, nano-TiO2 and MgO...

In this study, a nano-adsorbent was prepared for kerosene removal from water. Multiwalled carbon nanotubes (MWCNTs) were functionalized with concentrated HNO3 (nitric acid). Subsequently, Fe3O4 (magnetite) nanoparticles were deposited on the MWCNTs to prepare a magnetite/MWCNTs (Fe-MWCNTs) nanocomposite. Then, polyethylene was added to the Fe-MWCNT...

Abstract. The polymeric materials in this study underwent mechanical tests (tensile test, impact resistance and hardness), which explained the use of polymeric materials in engineering and industrial applications that need good mechanical properties compared to metals, ceramic materials and woods, and this is a good thing because it is characterize...

To date, numerous oily contaminants have posed a significant risk of severe pollution to the environment. In this study, functionalized multi-walled carbon nanotubes (MWCNTs) were impregnated with 2wt.% metal oxides (MxOy= TiO2, V2O5), respectively. The modified MWCNTs were successfully studied and characterized to determine the structure and chemi...

In this practical study, the thermal conductivity and compressive strength of a number of cement mortar and sawdust mixtures were measured. This study aims to analyze the possibility of using these mixtures as thermal insulators in the building parts. The materials used in the study were ordinary Portland cement available in the local Iraqi market,...

Abstract- The use of polymeric materials that have good mechanical properties compared with metals, ceramic materials and woods is a good thing because they are characterized by low cost and high efficiency with the application performance that has been studied. Therefore, the study of these properties reflected the good application of the material...

Abstract- There is no doubt that oil products have a clear effect on all materials, especially building materials, including concrete, so we must strive to improve the properties of chemical resistance and mechanical resistance in order to reduce the impact of oil, making it serviceable. Where it was studied how to reinforce concrete with wood ash...

Two types of polymer-based composite materials were made from locally available materials in the University of Technology-Iraq laboratories. The mechanical behavior of this new composite material (e.g., tensile, hardness and compressive strength as well as wear resistance) were tested under corrosive environment. Results showed an increase in wear...

Photovoltaic cells today have spread widely around the world and have begun to be popularly accepted and their stations have increased dramatically. The electricity provided by solar cells has become a significant part of the world's generated electricity. Because they are located outdoors, they are exposed to all weather variables such as air temp...

The deposition of dust on the solar cell surface causes an obvious degradation in its performance efficiency, and as the cell is always exposed to outdoor conditions the dust always accumulates on it. The recent study aimed to investigate the photovoltaic cells pollution with dust. As dust consists of several components, the formation of the deposi...
