Evaluating the effect of the substrate on the electrocatalytic performance of Cu2ZnSnS4 and Cu2ZnSnSe4 counter electrodes in dye-sensitized solar cells
(Elsevier, 2022)
The colloidal synthesis of Cu2ZnSnS4 (CZTS) and Cu2ZnSnSe4 (CZTSe) nanoparticles and their application as counter electrodes in dye-sensitized solar cells (DSSCs). In particular, the effect of three substrates namely; ...
Effect of Perceived Self-Vulnerability on Prostate Cancer Screening Uptake and Associated Factors: A Cross-Sectional Study of Public Health Facilities in Western Kenya
(Ubiquity Press, 2022)
Perceived self-vulnerability to prostate cancer is known to influence screening uptake among men in the general population. However, knowledge gap persists on the influence of perceived self-vulnerability to prostate cancer ...
An Analysis of Knowledge, Attitudes and Practices of Communities in Lake Victoria, Kenya on Microcystin Toxicity
(Scientific Research Publishing, 2022)
Exposure to microcystin poses a potential health hazard to humans and other living organisms. This results from eutrophication and warrants an investigation into the problem of microcystin toxicity in Lake Victoria. This ...
Effect of ridging and intercropping on sorghum productivity in arid and semi-arid lands of eastern Kenya
(African Crop Science Society, 2022)
Soil moisture deficit is a key constraint to sorghum (Sorghum bicolor) productivity in arid and semi arid lands globally. The objective of this study was to determine the effect of ridging and sorghum bean intercropping ...
Health care provider practices in diagnosis and treatment of malaria in rural communities in Kisumu County, Kenya
(BioMed Central, 2022)
Accurate malaria diagnosis and appropriate treatment at local health facilities are critical to reducing morbidity and human reservoir of infectious gametocytes. The current study assessed the accuracy of malaria diagnosis ...
Temperature-Dependent Elastic Constants of Substrates for Manufacture of Mems Devices
(Kabarak university, 2022)
We present a comparative computational study of temperature-dependent elastic constants of silicon (Si), silicon carbide (SiC) and diamond as substrates that are commonly used in the manufacture of Micro-Electromechanical ...
