Mr.Ayad Al-Thuwaynee studied manufacturing system engineering at UPM, Malaysia and graduated as MS in 2010. Then, he joined with research and development (R&D) department in ministry of industrial in Iraq. Currently, PhD student at Brighton university, UK. Undertaken study on the formation of the  nanoparticle by combustion flame synthesis.


Iron oxide nanoparticle (Fe2O3) is an important metal oxide and is expected to play an important role in many diverse applications such as catalysis, optical magnetic recording, gas sensors, electronic device. Particularly, functional iron oxide nanoparticles a highly attractive platform for biomedical application. For instance, drug delivery system, tissue repair, and magnetic resonance imaging, cell therapy, and cancer treatment. combustion synthesis have been commonly used to produce the nanoparticle in both premixed and diffusion flame. Diffusion flames are most commonly deployed by the scientific community for producing nanoparticles from flames. However, diffusion flames have not been used as widely for the synthesis of Fe2O3 nanoparticles as premixed flames. A novel normal diffusion flame (DF) burner was designed and utilized for flame synthesis.

The burner was modified by introducing a central burner tube for mixing fuel /air mixture. This configuration enabled homogenous mixing between the precursor and reactants along the burner zone. As flame conditions was set to stoichiometry at equivalence ratio=1.0. This work present synthesis process for producing functional iron oxide nanoparticles based on diffusion propane-air flame. Also, to evaluate the (DF) burner and its modifications to examine the effect of experimental conditions in diffusion flame on the synthesis of Fe2O3. The iron oxide nanoparticles were produced in propane (C3H8)/air diffusion flames using iron pentacarbonyl Fe(CO)5 and as the precursors. The results shows that the iron oxide nanoparticles are successfully produced in (NDF) burner. Also, The particle size was affected by the precursor rate. The synthesized nanoparticles are characterized using scanning electron microscopy (SEM) with energy dispersive X-ray spectroscopy (EDS) for elemental composition, and x-ray diffraction (XRD).
