Determination of Thallium and Indium with an Electrochemically-reduced Graphene Oxide-Carbon Paste Electrode by Anodic Stripping Voltammetry
(University of the Western Cape, 2018)
In this study, graphene oxide was synthesized by oxidizing graphite using the modified
Hummer's method. The graphene oxide was characterized by Raman Spectroscopy, Fourier
Transform Infrared Spectroscopy, High Resolution ...
Synthesis and Luminescence of Zinc Oxide Nanorods-Blended Thiopheno-Organosilicon Polymers
(University of the Western Cape, 2017)
The increasing cost of fossil fuel energy production and its implication in environmental
pollution and climate change created high demand for alternative and renewable sources of
energy. This has led to great interest ...
Complexation and Bioavailability of Dissolved Mercury Evaluation by Hplc and a Novel Au-Hydrogel Analytical Sensor Protocol.
(University of the Western Cape, 2017)
Anthropogenic sources as well as natural contributions (e.g. volcanic activity and evaporation
from the oceans) have increased mercury levels in the environment. Mercury deposits mainly in
sediments, and it finally ends ...
Phytochemical studies of extracts from Aloe succotrina
(University of the Western Cape, 2017)
Global climate change and geographical differences are two major parameters known to
have, either, direct or indirect influence on the production of secondary metabolites in plants,
which in-turn may affect the quality ...
Porous metal complexes for CO2 capturing
(University of the Western Cape, 2017)
The need in energy has resulted in the burning of fossil fuels at an increasingly high level.
The consequence is a release of high volumes of carbon dioxide gas (CO2) in the atmosphere.
This gas is a major greenhouse gas ...
Electrochemically enhanced ferric lithium manganese phosphate / multi-walled carbon nanotube, as a possible composite cathode material for lithium ion battery
(University of the Western Cape, 2019)
Lithium iron manganese phosphate (LiFe0.5Mn0.5PO4), is a promising, low cost and high energy density (700 Wh/kg) cathode material with high theoretical capacity and high operating voltage of 4.1 V vs. Li/Li+, which falls ...
Optical and electronic properties of methylammonium lead halide perovskite solar cells
(University of the Western Cape, 2017)
Organic-inorganic hybrid perovskite solar cells have emerged as promising materials for next-generation
photovoltaics with certified efficiency of 22.1%. Despite rapid developments, achieving precise control
over the ...
Electro-Luminescent and Photovoltaic Responses of poly (propylene imine) dendritic CuInSe2 (CIS) Quantum Dots
(University of the Western Cape, 2019)
The development of renewable energy has attracted more attention due to the increasingly serious energy and environmental crisis in the world nowadays. Second generation photovoltaics based on thin films of binary semiconductor ...
p- and e- type Semiconductor layers optimization for efficient perovskite photovoltaics
(University of the Western Cape, 2019)
Perovskite solar cells have attracted a tremendous amount of research interest in the
scientific community recently, owing to their remarkable performance reaching up to 22%
power conversion efficiency (PCE) in merely 6 ...
Synthesis of metal modified Mesoporous Zeolites catalysts: application in conversion of Olefins to Valuable liquid products
(University of the Western Cape, 2016)
The effects of temperature, synthesis duration and silica source were studied to obtain
suitable conditions for our laboratory experiment concerned with the synthesis of MCM-41
catalyst. The transformation of 1-hexene was ...
