Eric read BSc with major in Chemistry at Jomo Kenyatta University of Agriculture and Technology (JKUAT), followed by Postgraduate Diploma in Education at Moi University, conducting a final year project in the field of subject methods under the supervision of Prof. J. Agak. Eric progressed to study an MSc Nanoscience at the University of Nottingham undertaking a project under the supervision of Prof Martyn Poliakoff, FRS, CBE. Eric began his PhD studies at the University of Nottingham under supervision of Prof Robert Mokaya. During this time, his research concerned the probing optimal parameters for design, synthesis and characterise novel inorganic and carbonaceous at a nanometre (10-9 m) scale materials and study their structure-properties-applications relations. In September 2012, Eric conducted a postdoctoral research in the same group. In December 2013, Eric relocated to Kenyatta University upon appointment to the position of Lectureship/Researcher.
Research Summary
Exploration of novel materials that have improved properties, are cheap as well as environmentally benign. The materials under investigation in the emerging field of Nanotechnology are yet to be fully understood and in particular for Kenya’s situation that is not different from other developing economies. The insight into nanomaterials is vital in embracing of benefits that come with structure-property controlled synthesis of materials. Current research focuses on the optimal synthesis of Titania nanoparticles and silica for battery electrodes and water purification, respectively.

• Sigei Kipkirui Enock B.Ed (Sc. ) – REG No. 156/22808/2012; Topic: Low cost nanostructured silicon for high performance Li-ion battery anodes from rice husks (RH)
There is demand for powerful electrochemical energy conversion and storage devices of which Lithium ion technology is the most promising and is attracting a lot of attention due to its high energy density over other rechargeable technologies. However there is need to improve the electrode materials so as to achieve the highest possible energy capacity. The general goal for battery development is to increase energy and power densities, while minimizing volumetric and mass constraints. Nano-Si has attracted considerable attention as a promising anode material in next generation Li-ion batteries for electric vehicles and portable electronics. This interest is primarily due to its large theoretical specific charge storage capacity of 4,200 mAh g-1, which is more than ten times the theoretical capacity of conventional graphite anodes. While many guidelines for designing high-performance silicon anodes have been established, the existing methods for producing nano-Si anodes are still limited, complex, costly and energy intensive. Alternative fabrication methods that avoid the use of expensive processing are needed to produce Si anodes with comparable cost and scalability to graphite anodes. The recovery of useful materials from earth-abundant substances is of strategic importance for industrial processes. Pure Si nanoparticles (SiNPs) can be derived directly from rice husks, abundant agricultural byproduct. In this study new types of silicon nanoparticles will be extracted from rice husk by combustion and acid leaching for rechargeable batteries. Silica content and the amount of metallic impurities in the samples will be estimated by X-Ray Fluorescence spectroscopic technique. Crystallinity will be probed by powder X-Ray diffraction. The morphology and structure of Si nanoparticles will be characterized using Transmission Electron Microscopy and Scanning Electron Microscopy respectively. Galvanostatic cycling will be done using an MTI 8 Channels battery tester. The study is specifically geared towards providing documented information on amounts of elemental silicon from rice husk varieties available in Kenya and its suitability for high performance Li-ion battery anodes.

• Odhiambo Markus Okoth B. Ed (Sc. ) – REG No. I56/CE/ 21449/2012; Topic: The Thermo-chemical characteristics of peat as a potential gasfier fuel in the Lake Victoria region.
Gasification technology is one of the most efficient ways of converting biomass into energy; however, its scale up has failed to take off in a number of developing countries. East Africa and by extension the Lake Victoria Basin happens to be in this category. The Lake Victoria Basin (LVB) relies mostly on hydroelectric power for provision of modern energy. While hydroelectric power is sensitive to climate change, gasification technology has a high potential for reducing biomass energy consumption and increasing access to electricity and cooking facilities hence improving livelihoods and income. The key aspect for failure is the insufficient adaptation of gasification equipment to fuels characteristics, fuel specification and inadequate material choice of system components. The study will investigate the thermo-chemical characteristics of four peat fuels sampled from Yala in Nyanza province Kenya, Northern Rwanda province, Southern Rwanda province and from Uganda within the LVB. The proximate analysis involves moisture content, ash content and volatile matter, this will be determined in an oven and muffle furnace. Heating for calorific values will be determined using Gallenkamp Auto bomb calorimeter. The ultimate analysis will be determined using flash 2000 elemental analyzer.
