RESEARCH INTERESTS:

 Efficiency increase of solar panels using solar concentrator, cooling and dust cleaning procedure. With solar concentrator the output can be increased manifold using much smaller solar panel and thus the soiling & cooling effect on output can be easier to model and handle.  New Clean Energy Technology- Which can capture cost effectively the industrial emissions using only electrical power and no chemicals/reagent. Upon deep theoretical research together with an engineer we have invented the best cost effective cryogenic technique of separating & capturing each component of the flue gas from coal and natural gas power plants. The technique is expected to be the best answer for mitigating climate change & global warming to have the cleanest coal and natural gas power. A pilot plant project is planned for the best design of the capture plants for Indian thermal plants. A brief summary of the competitiveness of this technology over the existing technology is attached separately. Page 3 of 16

 Materials for high quality cost effective, energy efficient solid state natural white lighting. My Ph.D student and I have invented a new phosphor that gives the best natural white light to date in terms of chromaticity coordinates and color temperatures over broad band optical excitation. My focus is to come up with prototype working models of natural white light sources using LED that would ensure high energy saving and cost effectiveness. My plan is to use concentrated photovoltaic so that using a small solar panel and a parabolic concentrator and such energy efficient natural white LED{when finally produced [by my plan of research], we should be able to light a house at night without electricity from the main grid. Such lighting system would reduce stress on thermal power generation and hence promote clean air/ environment.  Modeling thermionic emission from nano-materials and solar thermionic power conversion with emitter of nano-materials. Our theoretical work shows that solar energy can be converted to electrical power with 50% efficiency using thermionic energy converter (TEC) with emitters of graphene and collectors of carbon nanotube, if we can tackle space charge problem using new innovations and by keeping the collector temperature around 800 K with emitter temperature above 3000 K. Work function engineering is going to play an important role in this thermionic solar energy conversion. My focus is to work on overcoming the associated theoretical and practical challenges and come up with a working solar TEC, using emitters of graphene and carbon nano tube.  Carbon capture and climate mitigation- In this area I am particularly working on patent

application of cryogenic capture of industrial toxic emissions and capturing CO2 from coal and natural gas fired power plants to ensure clean energy environment using no external cryogen and chemical reagents. This is a revolutionary invention I have made along with an engineer. I am currently making efforts to come up with prototype working equipment that can freeze all the emissions into frozen solids using only a small

percentage of output power. The frozen solids (CO2,SO2, NOx etc.) have tremendous industrial applications including future low cost refrigeration and air cooling systems, wildfire fighting systems.  Cost effective and energy efficient applications of renewable and conventional energy sources and energy storage devices.  Phase Transition and Jahn-Teller Effect in crystalline materials containing 3d transition metal ions, by EPR and allied techniques. Experimental and theoretical studies of effects of impurities on phase transition of solids. EPR and magnetic studies of effect of Jahn- Teller ions in properties of colossal magneto resistance (CMR) materials and multi- ferroic materials.  High Q and off resonance rejection, low insertion loss, Planar film YIG microwave resonators, notch filters, low phase noise wide band microwave oscillators. This is an area of research there is a great possibility of combining high Tc superconducting materials and YIG technology for advanced microwave devices.

Curriculum Development: I developed & implemented B.S, M.S. & Ph.D degree programs in Physics in several Universities. These include:

 Undergraduate Courses: Physics with electronics, Energy Physics, Industrial physics.  Graduate Courses: Medical Physics, Solid State Physics with Electronics; Energy Physics. Page 4 of 16

With the introduction of above courses, the undergraduate enrolment in Physics increased from 15 to 100 and the postgraduate enrolment increased from nil to 30 within two years in Federal University of Technology, Yola, Adamawa State. I have taught most of the courses on above subjects. The numbers continued to increase thereafter. I have reviewed curriculum for undergraduate & post graduate programs in Physics in five Universities over a period of 24 years. The review was required for accreditation of the academic programs every three years by national University Commission, Nigeria.

THESIS SUPERVISION I have supervised seven Masters and ten PhD students on various projects such as the energy dynamics of solar power conversions with metallic and nano emitters, MRI applications in blood flow estimation, nano-particle size effects on band gap, dependence of surface tension & viscosity coefficients of solution on solute concentrations, EPR studies of effect of 3d transition ion Jahn-Teller and non-Jahn-Teller impurities in phase transition of crystalline solids, electron-lattice non-equilibrium temperatures with nano and femto second pulsed laser pulses in metallic and semiconducting thin films etc.. I worked on applications of high-Tc superconductor that resulted in three US patents. I have also supervised about 100 undergraduate students' projects. My experience in the academia has allowed me help hundreds of students over the years and to develop a unique and effective approach to teaching.
