🔍 Research Focus: A Greener Pathway for Nanowire Synthesis
This study presents a pioneering method for synthesizing zinc oxide (ZnO) nanowires using a low-cost, scalable, and environmentally friendly technique known as Hot Water Deposition (HWD). Unlike conventional methods that require toxic chemicals, high vacuum, or extreme temperatures, the HWD method relies solely on hot deionized water and uses no chemical additives or catalysts. Zinc acts as the metal source, releasing ZnO molecules that migrate and form highly crystalline nanostructures on various substrate surfaces, including copper and indium tin oxide (ITO)-coated glass.

Key Research Outcomes:

• Development of a sustainable, low-temperature process for growing ZnO nanowires
   
• Successful deposition on various substrate types and geometries including Cu foam, mesh, and ITO/glass
   
• Structural validation using SEM, TEM, and XRD confirming high-quality, wurtzite-phase ZnO nanowires
   
• Introduction of an eco-friendly method compatible with real-world applications in sensing, electronics, and photonics
   

📈 Strategic Relevance to UOD
This study underscores UOD’s commitment to global research excellence and environmentally responsible innovation, aligning directly with the university’s Strategic Plan 2023–2038. The development of green nanotechnology supports UOD’s goals of advancing scientific knowledge, boosting interdisciplinary collaboration, and addressing sustainability through science and engineering. Furthermore, Dr. Saadi’s international collaboration with researchers from the University of Arkansas at Little Rock and Oak Ridge National Laboratory exemplifies UOD’s expanding role in global academic partnerships.

🗣 Dr. Nawzat S. Saadi remarked:
“HWD is a truly green route to metal oxide nanostructures that could transform the fabrication of next-generation sensors, electronic components, and biomedical surfaces. Our findings place UOD at the frontier of sustainable nanomaterials research.”
