Synthesis, Characterization, Electrochemical and Antibacterial Studies of Half-sandwich Ru(II) Complex of 4-fluoro-N-(2-pyridiylmethylene)-aniline Schiff Base
(2018-10)
The 4-fluoro-N-(2-pyridiylmethylene)-aniline Schiff base ligand (L) and its complex has been synthesized and successfully characterized by 1H NMR, elemental analysis, UV/VIS spectroscopy. Electrochemical properties were ...
Synthesis and insecticidal activities of some selected hydroxytriazenes
(2011-10)
Eight hydroxytriazenes were synthesized and then subjected to spot tests. The composition of these hydroxytriazenes was analyzed using elemental analysis and their physical characteristics like melting point, crystal shape ...

Geochemical and Mineralogical Characteristics of Geophagic Materials from Kiambu, Kenya
(Modern Scientific Press Company, Florida, USA, 2012-09)
Geophagia is the deliberate consumption of soil and clay. The practice of geophagia is due to reasons of culture, medicinal, religious and mineral deficiency. Geophagy is widespread among pregnant and ...
Effect of Human Activities and Seasonal Variation on Water Quality of Nkenye (Chikuu) Stream in Chuka, Kenya
(2013-01)
Composite water and sediment samples were taken from Nkenye stream at five different sampling stations during wet and dry seasons. Water quality parameters were analyzed using standard methods to ascertain ...
Spectrophotometric Determination of Iron(III) by New Analytical Reagents Derived from Coupling Arylhydroxylamine and Aryldiazonium Salt
(2012)
A highly sensitive and selective spectrophotometric method is developed for the determination of iron(III) in aqueous solution with hydroxytriazenes. In this work, the effect of pH variation, the composition of the complex ...
A study of new half-sandwich Osmium(II) complexes with bidentate N,N-chelating ligands and their use in the transfer hydrogenation of ketones
(2016-11)
The reaction of appropriate N,N-bidentate ligands with the [(η6-p-cymene)Os(μ-Cl)Cl]2 dimer, followed by metathesis reaction with NH4PF6, gave the new osmium(II) arene complex salts [(η6-p-cymene)OsCl(C5H4N-2-CH=N-R]PF6, ...
