Tuning the photoinduced charge transfer from CdTe quantum dots to ZnO nanofilms through Ga doping
(Elsevier, 2019)Tuning the charge transfer rate between quantum dots (QDs) and metal oxide (MO) is important for improving the performances of QDs-MO devices. And tailoring the energy band of MO is one way to tune the charge transfer rate. ... -
Turbulent Natural Convection in an Enclosure at Varying Aspect Ratio
(International Institute for Science, Technology and Education (IISTE), 2017)Energy transfer mechanism in most technical flows is through turbulent natural convection due to low viscosity of the fluids used in technical applications. Consequently, there is need to establish the parameters that ... -
Turbulent Natural Convection in an Enclosure at Varying Rayleigh Number
(International Journal of Science: Basic & Applied Research, 2017)Most fluids used in technical applications are of low viscosity; hence, fluid flows encountered in engineering applications are mostly turbulent. Parameters that influence the distribution of the ... -
Two new genera in Magnaporthaceae, a new addition to Ceratosphaeria, and two new species of Lentomitella
(2008)Ceratosphaerella is described as a new genus for C. castillensis and C. rhizomorpha. The genus is related to Ophioceras but distinguished by ascomata with a basal stroma and shorter, fusiform ascospores. Muraeriata is ... -
Two new genera in the Magnaporthaceae, a new addition to Ceratosphaeria and two new species of Lentomitella
(Taylor & Francis, 2008)Ceratosphaerella is described as a new genus for C. castillensis and C. rhizomorpha. The genus is related to Ophioceras but distinguished by ascomata with a basal stroma and shorter, fusiform ascospores. Muraeriata is ... -
Two new xylariaceous species from Kenya
(Mycotaxon, 2009)A survey of wood rotting ascomycetes in Kenya produced taxa in Biscogniauxia and Kretzschmaria that did not match descriptions of any known species and are hereby described as new species. The species of Biscogniauxia ... -
Use of zeolites in wastewater remediation
(Meru University of Science and Technology, 2022-06)Huge amounts of wastewater in low and lower-middle-income countries is released into the environment in untreated forms due to an increase in anthropogenic activities and disposal in water bodies. Pollution in water ... -
Variance Estimation for Poverty Indicators via Linearization Technique
(2018-08-24)In this study, an assessment of precision of poverty indicators is made with a view to improving its performance. A multiplicative bias reduction density function is used in estimating the poverty indicators and compared ... -
Variance Estimation in Stratified Random Sampling in the Presence of Two Auxiliary Random Variables
(International Journal of Science and Research, 2014)The objective of this paper is to develop an improved population variance estimators in the presence of two auxiliary variables in stratified random sampling adapting the family of estimators proposed by Koyunchu and ... -
Velocity Profiles of Unsteady Blood Flow through an Inclined Circular Tube with Magnetic Field
(Journal of Advances in Mathematics and Computer Science, 2017)The present paper is devoted to study the flow of incompressible viscous, electrically conducting fluid (blood) in a rigid inclined circular tube with magnetic field. The blood is considered to be Newtonian fluid and the ... -
Wide visible emission and narrowing band gap in Cd-doped ZnO nanopowders synthesized via sol-gel route.
(Elsevier Ltd., 2016)Cd doped ZnO nanopowder (Zn1−XCdXO, 0.15≤ X ≤0.45) has been synthesized by facile sol-gel method. The X-ray diffraction (XRD) shows the powder possess polycrystalline with hexagonal wurtzite structure of ZnO without formation ... -
(μ-Ethane-1, 2-diamine-κ2N: N′) bis [dicarbonyl (η5-cyclopentadienyl) iron (II)] bis (tetrafluoridoborate)
(International Union of Crystallography, 2011)The asymmetric unit of the title compound, [Fe2(C5H5)2- (C2H8N2)(CO)4](BF4)2, contains two half-cations, each located on a center of symmetry, and two tetrafluoridoborate anions. The iron atoms adopt a three-legged ... -
(μ-Formato-κ2O: O′) bis [dicarbonyl (η5-cyclopentadienyl) iron (II)] tetrafluoridoborate
(International Union of Crystallography, 2011)In the structure of the title compound [Fe(2)(C(5)H(5))(2)(CHO(2))(CO)(4)]BF(4), each Fe(II) atom is coordinated in a pseudo-octa-hedral three-legged piano-stool fashion. The cyclo-penta-dienyl ligand occupies three fac ...
