Green synthesis of iron oxide nanorods were achieved by utilizing rich polyphenols in
Omani mango tree leaves as a reducing agent. The obtained Iron (III) oxide nanorods
(IONRs) were (15 ± 2) nm in average length and (3.0 ± 0.2) nm in average diameter. These
nanorods were polycrystalline in structure with different diffraction planes indicating the
presence of a specific type of IONRs which are alpha phase, hematite (α-Fe2O3) and
gamma phase, maghemite (γ-Fe2O3). The relatively smaller size, distribution, and heat
conversion make the obtained nanorods a good candidate for heavy crude oil cracking
process. Direct microwave radiation causes a reduction in dynamic viscosity of crude oil
due to the presence of dipole water molecules. The viscosity reduction rate was found
to be higher when impregnated IONRs nanorods were placed within the heavy oil. The
viscosity was reduced by 10% when 0.2 g of IONRs was added to 1 L of heavy oil at T =
30 °C. This reduction increased up to 38% and 49% when 0.4 and 0.6 g/L additives were
added respectively at the same temperature. However, when 0.8 g of IONRs is added to
the heavy oil no noticeable change in the viscosity was found, indicating the oils’ additive
saturation point
Biography
Majid Salim Al-Ruqeishi is a Researcher in graphene and
nanomaterials fabrication field at physics department, faculty
of science, Sultan Qaboos University. He holds a bachelor in
science education (physics) from the Sultan Qaboos University,
SultanateofOman,2001andaMasterDegree inappliedphysics
(Radiation and Plasma) from University of Malaya, Malaysia,
August 2006. He acquired his PhD with full fellowship and a
minimum completion period certificate in solid state physics
(Nanotechnology) from the same university, August 2010. He
worked as a Scientific Researcher in Science division of Oman
National Commission for Education, Culture and Science, MOE,
2010-2012. Moving to sultan Qaboos University inspired him
to build nanofabrication and grapheme lab with his colleagues
where he supervised more than 30 final year students' projects
in the field of nanomaterial synthesis and development of
innovative applications in various energy fields. He published
more than 25 peer reviewed journal articles, 19 as a main
author. He takes keen interest in synthesizing nanomaterials
and graphene by physical and chemical methods especially
chemical vapor deposition technique (CVD) and to develop
smart Nano-based solutions for various energy issues. Most
recently, he received best researcher award in Sultan Qaboos
University for the year 2015-2016, during the University day, 2ed
May 2016. In addition, he was selected the best oral research
presenter inthe4th internationalconference innanoscienceand
nanotechnology, Kuala Lumpur, Malaysia, Jan 2016. Finally, he
awarded a Arab-American Frontiers Fellowship by US National
Academy of Sciences (NAS) to start collaborative research with
graphene research group at mechanical engineering, University
of Illinois at Urbana-Champaign (UIUC), Illinoi, Jan 2017.
