In this study, copper oxide nanostructures were prepared by an easy, simple, short time and economical electrochemical method using polyvinyl pyrrolidone (PVP) and polyvinyl alcohol (PVA) as stabilizing agents. Copper is used as precursors as melt anode electrodes during electrolysis to prepare CuO particles. The characterization of the prepared CuO NPs was studied by field emission scanning (FE-SEM), transmission electron microscopy (TEM) and atomic force microscopy (AFM). The FE-SEM images of CuO / PVA and CuO / PVP were both rectangle and regular cube shapes respectively. TEM images were prepared from CuO / PVA and CuO / PVP. They had an average size of 30-50 nm. The XRD results revealed the hexagonal structure of CuO nanoparticles. The optical properties of the prepared CuO / PVA and CuO / PVP nanoparticles were studied through UV / VIS spectroscopy. The optical band gap was found to be 3.60 eV and 3.75 eV for CuO / PVP and CuO / PVA. Dye solar cells were designed using CuO / PVA and CuO / PVP as positive electrodes (front electrode) and graphite as cathode (back electrode) deposition on the surface of ITO glass in the presence of two types of natural dyes, these are cabbage and spinach dyes, and iodine / iodine electrolyte solution. The PV cells prepared using spinach dye were more efficient. It is noticed from the data that the dye has a very important role in increasing the efficiency of the solar cell, as the cells made from spinach gave a much higher efficiency than the cells prepared from the red cabbage dye in all cases.

The Department of Chemical Engineering at the College of Engineering - University of Kufa organized a scientific trip for students of all levels to the Kufa Cement Factory affiliated to the Ministry of Industry and Minerals, on Monday 20/3/2023, under the supervision of a group of lecturers (Assistant Professor Asma Hassan Diaa, Assistant Professor Susan Ahmed Diaa, Assistant Professor Zainab Shaker Radeef, Assistant Professor Haider Abbas Ali, Assistant Professor Fouad Kazim Mahdi, Assistant Professor Adnan Abdul Jabbar, Assistant Professor Karar Jassim Ramadan, Assistant Professor Sahar Mahdi Jabbar, Assistant Professor Zainab Talib Abdul, Assistant Professor Lara Asim Kazar). The visit aimed to link the theoretical aspect with practical application, as the training, maintenance and quality officials in the factory provided detailed explanations of the different stages of cement production using the wet method, the mechanism of operation of the production units, as well as clarifying the most important chemical and physical properties of the final product (clinker). The students were also introduced to the use of modern technologies that rely on combustion with gas supplied by the Najaf Gas Power Plant as an alternative to black oil, in addition to periodic maintenance procedures that ensure the continuity of work in the various production departments. The laboratory currently operates in accordance with the international quality standards ISO 9001:2015 obtained from the French company Bureau Veritas and the Central Organization for Standardization and Quality Control, which has placed it among the leading laboratories locally and regionally in terms of product quality.

A workshop was organized in the Department of Chemical Engineering, where Ms. Lara Asim Kazar gave a workshop on Monday, March 10, 2025, entitled “Chemical Reactions in Solutions: Environmental Impacts and Industrial Applications.” She explained that chemical reactions in solutions greatly affect the environment through pollution and chemical waste, and are widely used in industrial applications such as water treatment and chemical manufacturing.

Ms. Lara Asem gave a workshop entitled “Working Women and the Art of Time Management,” in which she explained the most important challenges facing working women and how to manage their tasks between work and other duties.
