Synthesis and bioassays of Chilo partellus female sex pheromones and their analogues
(Depatment of Chemistry, University of Nairobi, 1994)Synthetic sex pheromones could provide valuable alternative means of pest control in Integrated Pest Management (IPM) strategies. Their uses could include population monitoring with pheromone traps to guide other control ... -
Synthesis and characterization of iron nanoparticles using banana peels extracts and their application in aptasensor
(University of Nairobi, 2016-11)Bio-inspired Iron nanoparticles were successfully synthesized by reduction of ferric chloride solution using aqueous solution of banana peel extract (BPE). The method was non-lethal, simple, eco-accommodating and relatively ... -
Synthesis and Characterization of Monomeric Magnesium and Zinc complexes supported by 1,5,9-Trimesityldipyrromethene for use in polymerization studies
(College of Physical and Biological Sciences, 2011)Magnesium and zinc complexes supported by a bulky bidentate ancilliary ligand have been synthesized and characterized. The compounds (pyac)MgnBu(THF),1; (pyac)Zn(nBu),2; (pyac)Mg(CH2CH2Ph)(THF), 3; (pyac)ZnEt, 4; and ... -
The synthesis and reactivity of 1,5-dioxaspiro[3.2]hexanes
(2001)A general synthesis of 1,5-dioxaspiro[3.2]hexanes is described. This was accomplished via epoxidation of 2-methyleneoxetanes with dry dimethyldioxirane. A study on the chemoselectivity of the epoxidation of the double bond ... -
Synthesis of Antimicrobial Benzene-1,4-diol Analogues of a Benzoquinone Metabolite From the Endophytic Fungi Xylaria Sp. Pbr 30
(University of Nairobi, 2017)The ever increasing problem of microbial resistance to currently available antimicrobial agents has led to a pressing need for development of new therapeutic and disinfecting agents. Although bioactive natural products ... -
Synthesis of Clay Derived Nanosilicates Impregnated With Prosopis Juliflora Biochar for Removal of Selected Heavy Metals in Water
(University of Nairobi, 2023)Due to growing urbanization, population growth, and industrial activity, heavy metals are now entering water bodies at a faster pace. The current treatment methods are ineffective, and this has detrimental effects for ... -
The synthesis of Vernolamides from Vernonia Galameinsis oil
(Depatment of Chemistry, University of Nairobi, 1998) -
Synthesis, Characterization and Anti-cancer Application of Platinum(Ii) Thiosemicarbazone Complexes
(UON, 2021)Coordination compounds have great potential as drug molecules. However, their instability, poor water solubility, and multi-drug resistance limit their use. Unstable coordination compounds may undergo unnecessary ligand ... -
Synthesis, Characterization and Application of Novel Palladium Complexes
(University of Nairobi, 2021)Palladium(II)thiosemicarbazone complexes are known to be good anticancer agents. However, their stability is a challenge during biological application because of faster ligand exchange kinetics. This research focused on ... -
Synthesis, Characterization and Photophysical Studies of Novel Porphyrin-based Compounds for Application in Photodynamic Antimicrobial Chemotherapy (Pact)
(University of Nairobi, 2020)There are a number of techniques employed to rid microbial contaminants from water. The inefficacy of some of these methods in removing microorganisms in contaminated water, has resulted to increased incidences of water-borne ... -
Synthesis, Characterization And Testing Of Titanium (iv) Oxide Tungsten (vi) Oxide Compound As Potential Catalysts For Water Purification
(University of Nairobi, 2013-07)The objective of this study was to synthesize Titanium (IV) Oxides tungsten (VI) oxide compound and subsequently test them for use as photo catalysts in water purification. The synthesized compound was calcined at 575DC. ... -
Synthesis, Structure Elucidation and Reactivity of Palladium(Ii) and Platinum(Ii) Complexes for Anticancer Applications
(University of Nairobi, 2020)The objective of the work was to come up with stable metal complexes with bulky ligands coordinated to the metal center and test them in anticancer studies. Literature reports that bulky ligands and trans geometry for ... -
A System for Credit Appraising - An application of the LogitBoost Algorithm
(School of Computing and Informatics, 2011)Mitigation of credit risk is a key aspect of portfolio management in any financial institution. This is chiefly due to difficulties in uncovering uncertainties in information provided by credit applicants and also due ... -
