Fabrication and Characterization of Germanium Doped Titanium Dioxide (Ge:TiO2)Thin Film for Photovoltaic Application
(2012)This study intends to realize 3 novel thin film material for photovo ltaic appl ications. Ti02 that has a I3rge band gap of 3.2eV is sensitized to visible light via the use of dyes in the Gratzel cell. The dye monolayer when ... -
Design and Construction of a Fishing Light Attractor
(2011)It has been known for a long time that light attracts fish: shrimp and insects at night In order to art rac 1 fish at night the fisherman needs to have a light attractor based on the biology of \ isual receptors of the fish ... -
Chemometric Trace Analysis and Spectral Imaging Approaches to Disease Diagnostics: Forays into Malaria and Cancer
(2014)The levels and speciation alterations, as well as correlations of trace chemicals (elements, metabolites) in human body tissues and fluids can be used as biomarkers for spectral diagnosis of disease as diseases lead to ... -
Niobium Doped Ti O, (Nb:Ti02) Effects of Doping Concentration on the Optical Properties of Ti O2
(28-04-14)The optical band gaps and crystal structure were inve stig ated on niobium doped TiO~ (for atomic niobium concentrations ranging from 0.02 -0.06 at. % in the composite) prepared by high temperature diffusion method. The ... -
Effect of Sn Doping on the Electrical Properties of as Prepared and annealed ZnO thin films Prepared by Reactive Evaporation
(28-04-14)Layers of transparent and conductive Sn-doped Zinc oxide (lnO) have been prepared by reacti. e evaporation on glass substrates. The deposition has been done at various doping levels ranging from J % to 8%. Annealing of ... -
Morphological and Stru crural Ch a r a cter iz.a tion of Ti02/N b20S Composite Electrode Thin Films Synthesized by Electrophoretic Deposition (EPD) Technique
(28-04-14)Composite electrodes of titanium dioxide (Ti02) and niobium (v) oxide (Nb?05) have been deposited onto glass substrates by electrophoretic deposition (EPO) technique. The mechanism of EPO involves charged particles in a ... -

Supporting Greater Access To Pre- And Post-Natal Information And Services For Women In Rural Kenya
(University of Nairobi, 2011)We present initial findings of on-going work, which examine pre- and post-natal services available to women in rural Laare, Kenya as well as cell phone appropriation by service providers and consumers as initial steps in ... -
A conceptual framework for designing mHealth solutions for developing countries
(University of Nairobi, 2013)Though mHealth is still at its formative stages, it is undeniably the next big thing in addressing healthcare challenges being experienced in developing countries. However, the complexity of implementing mHealth to address ... -
Assessing alignment of an e-government project in the context of a developing country: a Heideggerian perspective
(University of Nairobi, 2009)E-Government has increasingly become an alternative for enabling public governance at various. The situation is especially poignant in developing countries where there are increasing calls to improve governance for improved ... -
