Optical properties and Raman studies of amorphous se-bi thin films
(The African Review of Physics, 2014)Flash evaporated amorphous Se Bi (x = 0, 1, 2, 3, and 4 at. %) thin films of 350 ± 10 thickness have been investigated in the wavelength range of 200nm − 3000nm. It is found that the effect of increasing bismuth content ... -
Optical Properties of Seloo-Xbix Thin Films Deposited On Glass Substrates by Flash Evaporation Method
(Maseno University, 2014)The global need for sustainable energy production is pushing scientific research towards the development of inexpensive thin film solar cells which can compete with established commercial silicon-based technologies. These ... -
Optimal investment strategies of a defined Contribution pension fund
(Maseno University, 2019)The issue that a pension fund manager faces is how to optimize his/her investment strategies. The question we solve is the optimal design of the minimum guarantee in a defined contribution pension Fund Scheme. We study ... -
Optimised germination protocol for jackfruit seeds and evaluation of methods for extraction of DNA suitable for genetic analysis
(African Crop Science Society, 2022-08-18)Jackfruit (Artocarpus heterophyllus) is an underutilised plant that is promising in curbing food and nutritional security in sub-Saharan Africa. However, high level of secondary metabolites in its tissues significantly ... -
Optimising fermentation time in black tea manufacture
(Elsevier, 1986)A comparative study using in-line theaflavins analysis (ILTF), theaflavins of made-tea analysis (TFMT) and tasters' evaluations, to optimise fermentation during tea manufacture, was carried out. All methods obeyed a quadratic ... -
Optimization of biodiesel synthesis from Jatropha curcas oil using kaolin derived zeolite Na–X as a catalyst
(Royal Society of Chemistry, 2022)Biodiesel is an alternative renewable green fuel obtainable from the reaction of plant or animal oil with a low molecular weight alcohol in the presence of a catalyst. However, the cost of its production remains high due ... -
Optimization of Bioethanol Production from Sweet Sorghum Stalk (Sorghum bicolor (l.) Moench) Juice Using Response Surface Method
(Science publishing group, 2022)The use of fossil fuel as a source of energy has been unsustainable and has adverse effects to the environment. Bioethanol is a suitable alternative due to its exceptional properties. Bioethanol production can be done ... -
Optimization of Graphene oxide with methyl-β-Cyclodextrin and carbon Nanotubes with Polypyrrole for removal of lead (ii) and copper (ii) ions from water
(Maseno University, 2018)ABSTRACT Heavy metals pose risks to the humans and the environment. Lead (II) and copper (II) are of particular concern because they can cause irreversible damage to vital body organs. Their sources include leaded paints, ... -
