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; ...
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 ...
Isolation and detailed 1H and 13C NMR structural assignment for three trachylobanes from Psiadia punctulata (Asteraceae) grown in Africa
(Elsevier, 2022-04-01)
The first isolation of a trachylobane from an African specimen of Psiadia punctulata (Asteraceae) is presented in this paper. A complete 1H and 13C NMR spectral analysis of this compound and two other trachylobane diterpenes, ...
Utilization of fruit waste substrates in mushroom production and manipulation of chemical composition
(Elsevier, 2022-01)
The current study evaluated the effect of mushroom cultivation using fruit waste substrates on yield performance and antioxidant activities. The total phenolic content and the 2, 2-diphenyl-1-picrylhydrazyl (DPPH) radical ...
The effect of inoculating Bradyrhizobium liaoningense on growth, chlorophyll concentration, nodulation and yield of soya beans
(SciCell publishing company, 2022)
Soya bean is important staple food crops in Western Kenya. Legumes play a significant role in agriculture by fixing nitrogen. Currently Kenya is experiencing low yield of soya beans. Approximately 0.8 t/ha is under production ...
Monoaminergic system involvement in the antidepressant-like and anxiolytic-like properties of novel β-dihydroagarofuran sesquiterpene alkaloid and triterpenes isolated from Gymnosporia heterophylla aerial parts in mice
(Pergamon, 2022)
Gymnosporia heterophylla (synonym Maytenus) is widely used in folk medicine for the treatment of various illness including neurological diseases. This study presents the antidepressant-like and anxiolytic-like effects of ...
Anomalous photovoltaic behavior under illumination of γ-In2Se3 nanostructures used as hole transport layer in organic solar cell
(Pergamon, 2022)
Indium selenide is currently receiving tremendous attention in device application and studies related to two dimensional nanostructured technologies. Non-layered γ-In2Se3, which is a stable phase at room temperature, was ...
Accurate Ab-initio calculation of elastic constants of anisotropic binary alloys: A case of Fe–Al
(Solid State Communications, 2022)
The final formed phases of alloys are functions of the chemical compositions of the mixture. The overall mechanical moduli of the alloy are also functions of the phases present. Most of the previous computed elastic constants ...
Structural and Optical Probe into Rare Earth Doped ZnO for Spectral Conversion in Solar Cells
(Jenny Stanford Publishing, 2022)
This chapter examines the relationship between structure and optoelectronic properties of rare earth doped Zinc oxide (ZnO) thin films fabricated by RF magnetron sputtering for photovoltaic applications. A doped ZnO layer ...
