Nitrogen Doping of Hexagonal and Cubic Ge2Sb2Te5 Nanocrystals: An Ab Initio Study
(World Scientific Publishing Company, 2018)
The effect of nitrogen doping on the structural, electronic and optical properties of hexagonal and cubic Ge2Sb2Te5 (GST) has been investigated from first principles. The nitrogen content was set to 10 at.% and 25 at.%, ...
Effect of Reverse Bias on Dye-Sensitized Technology: Lessons for Application in PV-Integrated Textile Fabric Designs Useable in Wajir, Vihiga, Kitui and Kajiado Counties in Kenya
(Journal of Technology Innovations in Renewable Energy, 2018)
This paper reports on the effect of reverse bias (RB) on dye-sensitized solar cells (DSSCs) that were investigated outdoor in Wajir (1o4450 North, 40o 4 8 East), Vihiga (35o0 East, 0o15 North), Kitui (3o 0 South, 37o 50 ...
Morphological Characterisation of Global Finger Millet (Eleusine coracana, L. Gaertn) Germplasm Reaction to Striga in Kenya
(journaajbgmb, 2018)
Finger millet (Eleusine coracana, L. Gaertn) is an important food crop in Africa and Asia. Its grain is richer in protein, fat and minerals than other major cereals. The parasitic weed Striga hermonthica (Del.) Benth ...
Spatial distribution and habitat characterization of mosquito species during the dry season along the Mara River and its tributaries, in Kenya and Tanzania
(Bio Med Central, 2018-12)
Vector-borne diseases are increasingly becoming a major health problem among
communities living along the major rivers of Africa. Although larger water bodies such as
lakes and dams have been extensively researched, ...

Optimizing production of biodiesel catalysed by chemically tuned natural zeolites
(Elsevier, 2018-12-31)
The twin crises of fossil fuel depletion and environmental degradation coupled with their unpredictable prices is a reality. Biodiesel is a promising, viable and environmentally friendly alternative. However, production ...
Efficient adsorption of lead (II) and copper (II) from aqueous phase using oxidized multiwalled carbon nanotubes/polypyrrole composite
(Taylor & Francis, 2018-01-12)
Polypyrrole coated oxidized multiwalled carbon nanotubes (oMWCNT/Ppy) were applied to determine the adsorption characteristics of Pb(II) and Cu(II) from their aqueous solutions. Structural and morphological characterization ...
Inorganic Chenistry 1
(2018-03-10)
Introductory Chemistry 1 undepins the concepts of matter, measurements, structure and periodicity of the atom, Molecules and compounds, and their chemical reactions. This study builds on the aforementioned concepts by being ...
