Instructor at the University of Samarra publishes a scientific research paper in a journal indexed in Scopus and Clarivate

Dr. Osama Ahmed Yassin, an instructor on the faculty of the College of Education for Pure Sciences at the University of Samarra, has published a scientific research paper in the Journal of Molecular Structure, published by the international publishing house Elsevier in the Netherlands and classified in the first quartile (Q1) in both Scopus and Clarivate databases.

The research is titled \”Schiff base complexes involving manganese (II), nickel (II), cobalt (II), copper (II), and zinc (II) cations: Synthesis, density functional theory (DFT) calculations, and biological activity.\” In it, the researcher sought to study how the type of metal ion affects the physicochemical properties and antibacterial activity, and to prepare a new Schiff base derivative (HCPfide) and a homologous series of its metal complexes with manganese, cobalt, nickel, copper, and zinc ions.

The results proved that the zinc complex had the highest inhibitory capacity against various types of bacteria (such as S. aureus and E. coli), with effectiveness approaching that of the standard antibiotic tetracycline. Calculations showed that the manganese complex has the smallest energy gap (3.334 eV), indicating high chemical reactivity.

Spectroscopic data and TD-DFT calculations revealed that the prepared complexes possess octahedral geometries.

Additionally, the chelation process increases the lipophilicity of the compounds, facilitating their penetration of bacterial cell membranes and stabilizing their effectiveness.

In turn, the Department of Media and Government Communication congratulates Dr. Osama Ahmed Yassin on his new scientific achievement, wishing him continued success in his academic and research career.
