Functionalisation of polymer nanofibres and track-etched membrane removal of organic and and inorganic pollutants from water
(University of the Western Cape, 2017)
Organic and inorganic pollutants are two broad classes of pollutants in the
environment with their main sources from waste waters that are indiscriminately
dumped from chemical related industries. Among the organic ...
The effect of flow field design on the degradation mechanisms and long term stability of HT-PEM fuel cell
(University of the Western Cape, 2018)
Fuel cells are long term solution for global energy needs. In current fuel cell
technologies, Proton Exchange Membrane (PEM) fuel cells are known for quick start-up
and ease of operation compared to other types of fuel ...
Hydrogel encapsulated biosensors for the detection of biologically significant vanadium and selenium
(University of the Western Cape, 2017)
Vanadium and selenium salts are toxic in large amounts, but trace amounts are
necessary for cellular function in many organisms. Exposure to high level of selenium
has been linked to delays in early childhood development ...
Aluminium and gold functionalized graphene quantum dots as electron acceptors for inverted Schottky junction type rainbow solar cells
(University of Western Cape, 2020)
The main aim of this study was to prepare band gap-engineered graphene quantum dot (GQD) structures which match the different energies of the visible region in the solar spectrum. These band gap-engineered graphene quantum ...
Thermochemical Storage and Lithium Ion Capacitors Efficiency of Manganese-Graphene Framework
(University of the Western Cape, 2018)
Lithium ion capacitors are new and promising class of energy storage devices formed from a combination of lithium-ion battery electrode materials with those of supercapacitors. They exhibit better electrochemical properties ...
Graphenated electrode protocol for electrochemical nanosensing of 17β- estradiol as an environmental estrogeneous endocrine disruptor
(University of the Western Cape, 2016)
17β-Estradiol can be defined as an endocrine disruptor chemical with estrogenic activity, which
can bind to the estrogen receptor in the body and potentially alter the normal physiological
function of the endocrine ...
Advanced materials on the basis of nanostructured catalysed magnesium hydride for hydrogen storage
(University of the Western Cape, 2019)
Magnesium hydride has long been regarded as a promising candidate for lightweight hydrogen storage applications, owing to reasonably high theoretical capacity (7.6 wt. %). It is burdened by slow absorption/desorption ...
Treatment of persistent organic pollutants in wastewater with combined advanced oxidation
(University of the Western Cape, 2019)
Persistent organic pollutants (POPs) are very tenacious wastewater contaminants with negative
impact on the ecosystem. The two major sources of POPs are wastewater from textile industries
and pharmaceutical industries. ...
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 ...
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 ...
