Welcome to the Digital Repository for the Faculty of Education

The Digital Repository for the Faculty of Education is a dedicated platform for preserving and providing access to academic and research resources for faculty members, students, and researchers. This repository aims to promote knowledge sharing, facilitate access to studies and academic projects, and support research collaboration.

The faculty comprises four academic departments and postgraduate programs in the near future

Explore a wealth of studies and research, and become a part of advancing scientific knowledge and contributing to innovation through our digital repository.

Novel preparation method of fullerene and its ability to detect H2S and NO2 gases
(Results in Chemistry, 2023) Mohammed Faiad Naief; Samar Naser Mohammed; Yasser Naji Ahmed; Ahmed Mishaal Mohammed; Sura Naser Mohammed
In this study, a new system for fullerene preparation was designed based on the incomplete combustion of liquid asphalt. Transmission electron microscopy, field emission scanning electron microscopy and energy-dispersive X- ray (EDX) techniques were used to characterise fullerene. The sizes of the synthesised fullerene ranged from 48.20 nm to 73 nm. The EDX technique was used to determine the amounts of elements in a component, thereby revealing the formation of fullerene. The produced fullerene was evaluated as a gas sensor for H2S and NO2 gases at various temperatures and time intervals. The sensitivity of the gas sensor decreased with the increased operating temperature reaching 150 ◦C. Then, the sensitivity increased as the temperature increased. The maximum gas sensitivities for NO2 and H2S were 72.86% at 25 ◦C and 75.89% at 200 ◦C, respectively.
Synthesis and characterisation of MWCNTCOOH and investigation of its potential as gas sensor
(journal homepage, 2023) Mohammed Faiad Naief; Samar Naser Mohammed; Yasser Naji Ahmed; Ahmed Mishaal Mohammed
Monitoring and control of hazardous gases have been a top concern because they lead to serious public health issues, such cardiovascular diseases, respiratory illnesses, central nervous system abnormalities and other ill nesses. These gases are also linked to global warming, which affects the surrounding environment. Therefore, harmful emissions should be limited and neutralised. Traditional gas sensors have slow speed, expensive oper ation, labour and capital intensive and invasive. Scholars need to develop an inexpensive, rapid, efficient, highly sensitive, portable sensors with a low power consumption and a high level of reliability. In this study, multi- walled carbon nanotubes (MWCNTs) were synthesised using plant byproducts. TEM, FE-SEM and AFM were employed to identify MWCNTs. Gas test showed that the sensor had high sensitivity levels of 5.6 and 8.8 and response times as low as 24.3 and 21.6 s for H2 S and NO 2 , respectively.
