The textile industry is a major source of environmental pollution due to the discharge of highly colored and chemically complex wastewater containing toxic, mutagenic, and carcinogenic compounds that are often resistant to conventional treatment. Although conventional chemical coagulants and flocculants such as alum and synthetic polymers are effective, their application raises concerns about excessive sludge generation, residual toxicity, and long-term environmental impacts. This short review c [...]

A new series of bis-quadridentate ligands (L₁-L₃) and their corresponding zinc(II) complexes (Complex 1-3) were rationally designed, synthesized, and characterized. The ligand framework features multiple donor sites that enable stable coordination to zinc(II), yielding well-defined metal complexes. The structures of the synthesized compounds were confirmed using a combination of analytical and spectroscopic techniques. Thermal gravimetric analysis re [...]

Molecular dynamics is an essential tool for studying the formation of surface patterns in their early stages under low-energy bombardment. Recently, it has been shown that semiconductor surfaces such as Si can reorganize under ultra-low-energy conditions to form surface patterns. In this work, we investigate the formation of patterns on metal surfaces under these conditions. To accelerate the process, a longitudinal substrate model was employed, with clusters selected as projectiles. As is well [...]

This study explores the use of plant extract to reduce corrosion on low-carbon steel reinforcement embedded in concrete. It is globally known that structures exposed to corrosive environments can collapse due to deterioration of the steel rods embedded in the concrete. The corrosion-inhibition potential of leaves, bark, and root extracts of Boswelia dalzelia (BD) on concrete reinforcement was investigated using a half-cell potentiometer and scanning electron microscopy (SEM) [...]
