Characterization of Vibrio cholerae Bacteriophages Isolated from the Environmental Waters of the Lake Victoria Region of Kenya
(2013)
Over the last decade, cholera outbreaks have become common in some parts of Kenya. The most recent cholera outbreak occurred in Coastal and Lake Victoria region during January 2009 and May 2010, where a total of 11,769 ...

Surface Photovoltage Study of Surface Defects on Co-Doped TiO2 Thin Films Deposited by Spray Pyrolysis
(University of Nairobi, 2016)
Surface photovoltage (SPV) spectroscopy is a powerful tool for studying electronic defects
on semiconductor surfaces, at interfaces, and in bulk for a wide range of materials. Undoped and
Cobalt-doped TiO2 (CTO) thin ...
Identification and Sorting of Materials With Portable Libs Before Decommissioning
(University of Nairobi, 2016)
Laser Induced Breakdown Spectroscopy (LIBS) is a technique of elemental analysis. A laser beam is
focused on the surface of the sample to be analyzed. A small quantity of matter is ablated and a plasma
formed by the ...
A Simplified Simulation Procedure and Analysis of a Photovoltaic Solar System Using a Single Diode Model
(University of Nairobi, 2020)
A single diode model for a photovoltaic solar module is the most ideal and
quick way of analyzing the module characteristics before implementing them
in a solar plant. Solar modules manufacturers provide information for ...
A Simplified Method for Parameter Determination of a Photovoltaic Module using Manufacturer’s data
(University of Nairobi, 2020)
Accurate and fast modelling and simulation of Photovoltaic module
requires careful determination and identification of the unknown
parameters required in fitting the voltage-current and power-voltage
curves to replicate ...
Optical properties of amorphous Se90-XIn10SbX thin film alloys
(University of Nairobi, 2016)
Ternary thin film alloys of Se90-XIn10SbX (x = 1, 4, 10, 15 and 20) were synthesised by flash evaporation of the pre-melt quenched bulk samples under a vacuum of 10−5 Torr. Optical absorption analysis pointed to indirect ...
Angle resolved photoemission study of surface states on the Pt(997) vicinal surface
(University of Nairobi, 2010)
One-dimensional atomic chains can be synthesized on stepped surfaces and the electronic structure of the high vicinal surface plays an essential role in determining the physical properties of atomic chains grown on top of ...
