Ab initio insights into Graphene-Zirconium disulfide/diselenide heterostructure as electrode material for alkali-ion batteries
(Surfaces and interfaces, 2021)In the search for an energy storage medium with higher electronic conductivity, rate performance and moderate volume expansion, van der Waals heterostructures are a promising alternative. Herein, the potential of graphene ... -
Breeding Grain Sorghum for Tolerance to Aluminium Toxicity
(AER Journal, 2020)Aluminium (Al) toxicity is a common problem in acid soils where sorghum (Sorghum bicolor (L.) Moench) is grown. It contributes to grain yield reduction of between 30-40 % in sorghum and other cereals. Al interferes with ... -
On Unitary Invariance of Some Classes of Operators in Hilbert Spaces
(Pure Mathematical Sciences, 2020)It is a known fact in operator theory that two similar operators have equal spectra but they do not necessarily have to belong to the same class of operators. However, under the stronger relation of unitary equivalence ... -

Two-dimensional graphene–HfS2 van der Waals heterostructure as electrode material for alkali-ion batteries
(The Royal Society of Chemistry, 2020-07)Poor electrical conductivity and large volume expansion during repeated charge and discharge is what has characterized many battery electrode materials in current use. This has led to 2D materials, specifically multi-layered ... -
SYNTHESIS AND CHARACTERISATION OF NICKEL AND PALLADIUM BIMETALLIC COMPLEXES AND THEIR CATALYTIC APPLICATION IN OLIGOMERISATION OF 1-HEXENE
(University of Eldoret, 2022)In this work, typical homobimetallic complexes derived from N,O-salicylaldimine ligands were investigated for their catalytic potential in oligomerisation of 1-hexene. Catalysts of monometallic nature, that is, those ... -
INTEGRATION OF VCSEL WITH MODULATED RAMAN PUMP FOR DATA AND CLOCK TRANSMISSION IN OPTICAL COMMUNICATION
(University of Eldoret, 2022)The evolution of ultrafast optical technologies has led to the realization of low cost, low latency and high speed optical networks. Existing telecommunication infrastructure does not provide sufficient capacity to satisfy ... -
THE SPATIAL AND TEMPORAL VARIATION OF SELECTED HEAVY METALS, NITROGEN AND PHOSPHORUS IN WATER AND SOILS OF YALA SWAMP, KENYA
(University of Eldoret, 2013)Studies involving pollutants in the environment have been used as an indicator of their accumulation resulting from human activities. A study of spatial and temporal variation of pollutants involving forty four water and ... -
DETERMINATION OF BACTERIAL LOAD AND DIVERSITY IN SELECTED SITES IN LAKE NAKURU, KENYA AND THEIR ABILITY TO DEGRADE PLASTICS AND PETROLEUM OIL
(University of Eldoret, 2013)Halophilic bacteria have been largely omitted from ecosystem studies of saline Lakes, especially with regard to their importance in decomposition process under aerobic conditions. Plastics are widely used as packaging ... -
EFFICIENCY OF UNIVERSITY OF ELDORET SEWAGE TREATMENT SYSTEM USING BIOLOGICAL INDICATORS
(University of Eldoret, 2016)At the University of Eldoret, wastewater is treated using sewage treatment ponds. These ponds were constructed to cater for a few students when the university was a Teacher’s Training College. Since then, the treatment ... -
FIELD DEPENDENCE OF THE PROPERTIES OF HIGH-TEMPERATURE SUPERCONDUCTORS
(University of Eldoret, 2016)High temperature superconductivity mechanism has remained an elusive concept for a long time. Field dependence of the properties of high temperature superconductors could be on the brink of solving this puzzle. This Study ... -
