Master's degree in the field of manufacturing nanomaterials from environmentally friendly materials

 

 

The Department of Materials Engineering at the University of Technology awarded a master's degree to the student, Ali Hussein Abdul Jabbar, Department of Materials Engineering / University of Technology for his thesis titled

"Green Synthesis and Surface Modification of Nanoparticles for Wastewater Treatment"

Abstract

This study focused on the green synthesis of silver nanoparticles using two separate heating techniques—hotplate and microwaves—with turnip root extract as the reducing and stabilizing agent. Furthermore, the green synthesis of graphene foam using date syrup carbon source, combined with potassium chloride as a substrate. The foam was modified with the prepared silver nanoparticles to enhance heavy metal removal and antibacterial efficiency. Silver nanoparticles with an average size of 47.5 nm, confirmed by scanning electron microscopy (SEM), demonstrated stability via zeta potential analysis. The graphene foam's morphology and structure were characterized using SEM and Raman spectroscopy. Filtration tests by atomic absorption indicated high removal efficiencies for cadmium (68%) and lead (39%), with lower efficiencies for zinc (10%) and chromium (27%). The addition of silver nanoparticles improved removal efficiencies for Cd²⁺ (75%), Zn²⁺ (22%), and Cr²⁺ (33%). The antibacterial efficacy test showed a 100% bacterial-killing rate post-modification.

Abstract

The study aims to fabricate geopolymer concrete with high mechanical properties and acceptable thermal insulation using waste materials like fly ash, Kufa cement plant waste, and glass waste powder. The concrete's mechanical properties were evaluated using tests like hardness, compressive strength, flexural strength, and splitting tensile strength. In contrast, water absorption, porosity, and thermal insulation tests used to evaluate physical properties, X-ray techniques, infrared spectroscopy, and scanning electron microscopy were used to evaluate the structure and chemical composition. The results show the possibility of manufacturing environmentally friendly concrete using some waste that has better mechanical and thermal insulation properties with minimal CO2 emissions than ordinary Portland concrete.

Abstract

This study involved the green synthesis of copper oxide and iron oxide nanoparticles three times using peel extracts from orange, cherry, and sidr. It also included creating a nanocomposite of these oxides from cherry and sidr peels. The nanoparticles' structural, biological, physical, and toxicity properties were analyzed. The impact of adding these oxides on concrete’s mechanical and physical properties was examined. Electrochemical tests showed that copper-iron oxide nanoparticles significantly improved the corrosion resistance of reinforcing steel, with a corrosion efficiency of 86.8% and a 57% improvement in concrete containing this oxide.
