LETTER OF COMMENDATION FROM THE GOVERNING COUNCIL

 My Research Focus and Contribution to Knowledge

Since 2005, my research efforts have been directed towards: (1) Synthesis and application of POSS hybrid nanocomposite with applications in various functional industrial and engineering materials (2) Living polymerization of olefins (3) Nanoporous membrane materials for water filtration (4) Synthesis and applications of nanobimetallics (Ag and its allied metals) using wet chemistry (sol gel) (5) Synthesis and application of nanosilver using chemical and “green nanotechnology” (6) Electrospun nanofibrous materials for crude oil separation and spillage remediation. (7) Forensic: Fingerprinting and Anticounterfeiting (8) I have been involved in few other co-opted and collaborated research subjects outside nanotechnology and materials. My major scientific contribution to knowledge and breakthrough lies on:

  • Development of novel process for POSS nanocomposite synthesis.

POSS is a hybrid nanocomposite material possessing nanoscopic size with Si – Si distance of 0.5 nm and an R – R distance of 1.5 nm characterized with various reactive groups at the periphery of the cage [Figure 1].

Figure 1: POSS Anatomy

Extensive research on POSS as semiconductors, light emitting diodes and other electronic have been done by many Companies and Universities, including Dow Corning, IBM computer, e.t.c. These materials have been extensively used in semiconductors owing to its tunable periphery functionalities. With electronic getting smaller and smaller, the need for materials that keep these devices from short-circuiting is growing in demands. POSS properties have the ability to prevent short-circuiting by acting as rigid and providing durability for devices —  However, in-spite of the aforementioned importance of these great materials, its synthetic process and conversion rate leaves much to be desired in which Octavinyl-POSS and H-POSS were obtainable in yield of 7% and 21% respectively before 2006. Breakthrough: In the years 2006, Prof. Liu, James Peng and I innovatively moved the yields of Octavinyl-POSS and H-POSS to 41% and 72 % respectively by adopting a novel modified synthetic procedure as detailed in a Royal Society of Chemistry, UK Journal (Dalton Transaction) (PAPER NO 12). Since then, several efforts have been put to create functional materials (e.g. hydraulic lubricant for off-road machines, silicon oxycarbide special glass) from POSS nanocomposites as detailed (PAPERS NO. 2 – 12).

  • Nanoporous water filter membrane for water purification and its impact on health status of a local community

As you know, a new paradigm for approaching environmental and quality of life is unfolding —– Nanotechnology. Provision of affordable and clean water services to the “unconnected” in rural areas is a prerequisite to poverty alleviation which determines quality of life. I was privileged to be a major contributor to the national and international clarion call for the development of nanoporous water filter from agricultural wastes (saw dust, rice husk ash) and clay. My previous invited research visit to Princeton University, NJ, USA prompted a return visitation of our collaborators to my laboratory in Nigeria. Within one months of their stay in Abeokuta, a program tagged “Grand Challenges Programme on Ceramic Filter for Portable Water”  (http://sig.ias.edu/files/pdfs/USAMI-RISE-Presentation.pdf) was organized. A preliminary research in this direction and application of the filter device on a local community in Abeokuta, Ogun state, offered us a value – added – product [PAPER NO 18, 24, 25, 48, 95], which, however, my indigenous research group and I were positively disposed to improve upon. Several improvements have been made leading us to some developmental stages [Figure 2].

Figure Y: Nanoporous Water filter developed [Paper No. 95]

It is noteworthy that effort put towards stage C credited my group with an award as the second best in a National University Commission (NUC) – organized research innovation competition (see attachment).

(C)  Nanobimetallic and Green nanotechnology : Using various nanostructuring methods, I have been able to

synthesized and evaluate properties of silver nanoparticles. Many of these nanosilvers found inhibition against

offensive bacterials, virus and fungi.. However, providing synergy to nanosilver via “green  nanotechnology” using various medicinal plant extracts vis-à-vis mopholine, potentially, would be a “hopeful future” toward Ebola  containment. This, I have started working on with records of success stories [PAPERS NOS 38, 43, 51-56, 71, 94]. I have also synthesized various hybrids-silver nanoparticles using wet chemistry and they have found applications in catalysis and sensors [Papers nos 41, 42, 44, 45, 54].

(D): Surface Science: Crude Oil Spill Remediation vis-à-vis CRUDE OIL SEPARATION

         

Figure 3: Crude oil separation prototype developed (repacked as boom or pad) [Paper No. 53 – 55 + Patent]

We have objectively achieved this in this project leading us to electrospun nanoporous sorbent boom that is cheap, reusable and sustainably suitable for wider crude oil dewatering/deoiling (figure 3, Paper No. 57-60, 65, 69). Furthermore, we have been able to innovatively create several novel functional POSS, which have proven record of excellent surface properties. The combination of the inorganic group in the hybrid system and the microcrystalinity of the material make it one of the lowest surface energy materials known, imparting hydrophobic and oleophobic properties. Indeed, my research group [Papers No: 43-46] has also developed modified procedure leading to a number of derivatized POSS possessing hydrophobic/oleophobic properties for crude oil purification. Lately, a switchable dual functional nanofibrous sorbent that reversibly switch as it dewatered – deoil crude oil was proposed.

(E) Petroleum fingerprinting: In order to circumvent incidental danger arising from adulterated petroleum products which has led to severe explosion and environmental disorder, we did use the concept above (electrospun nanoporous sorbent) to develop sustainably reuseable materials capable of correlating and differentiate adulterated petroleum via it geochemical fingerprint (Papers no. 60, 65 ). Dr. Samson Alayande and Prof. Msagati are major contributor.

F: FORENSIC SCIENCE: Human Fingerprinting, Anti-counterfeiting and Geochemical fingerprinting: Public, social

     and environmental security remain a global phenomenon. The advancement of forensic science has drastically

improved public and environmental security. To contribute in this direction, we have adopted fluorescently labeled

materials for the detection of fingerprints and anti-counterfeiting bar codes in criminality detection.

Environmental security requiring detection of adulterated petroleum products has been mentioned in (E) above

(Papers no: 60, 65) as part of my contribution to knowledge

G: Transdermal Drug Delivery: I have also looked into Transdermal Nanoemulsion (Figure 4) as an effective

      controlled insulin delivery system (Papers no: 63, 68, 91) using nanoemulsion as carrier.

Figure 4: Transdermal drug delivery approach

 

H: Theoretical Chemistry: I am not limited to experimental chemistry (A – G) above. First-principles study of

      zinc-blende BxAlyIn1-x-yN quaternary alloy was achieved using Alchemical mixing approximation approach. The

results indicate that Zinc- blende alloys are suitable candidates for deep ultra- violet light emitting diodes (LEDs),

laser diodes (LDs) and modern solar cell since the concentrations x and y make the bandgap and lattice constant of

the quaternary alloys tunable to desirable values (Paper no. 64, 70). Prof. G.A. Adebayo is one of the major

contributor.
