Electrospinning of porous composite materials for hydrogen storage application
(University of the Western Cape, 2016)
Due to the rapid depletion of fossil fuel reserves and the production of environmentally harmful by-products such as carbon dioxide, there is an urgent need for alternate sustainable clean energy. One of the leading ...
Designing next generation high energy density lithium-ion battery with manganese orthosilicate-capped alumina nanofilm
(University of the Western Cape, 2015)
In the wide search for advanced materials for next generation lithium-ion batteries, lithium manganese orthosilicate, Li₂MnSiO₄ is increasingly gaining attention as a potential cathode material by virtue of its ability to ...
Detection of selective tyrosinase inhibitors from some South African plant extracts of lamiaceae family
(University of the Western Cape, 2016)
Various dermatological disorders, such as formation of black pigmented patches on the surface of the skin arise from the over-activity of tyrosinase enzyme's degenerative action. This enzyme is further implicated in the ...
The preparation of an immunosensor for the detection of microcystins and nodularins by immobilisation of a labelled antibody onto a polymer modified electrode
(University of the Western Cape, 2011)
South African dams and reservoirs are increasingly showing the propensity to support sustained populations of Cyanobacteria (blue green algae). These photosynthetic bacteria occur throughout the world and can rapidly form ...
Electrochemical in-situ polymerization of graphene oxide/conducting star copolymer nanocomposite as supercapacitor electrode
(University of the Western Cape, 2017)
These days there are deep concerns over the environmental consequences of the rate of
consumption of energy from non-renewable sources because of the accelerated increase in greenhouse effect. There is, therefore, increasing ...
Overoxidized polypyrrole-osmium telluride quantum dots immunosensor for prostate specific antigen – A cancer biomarker.
(University of the Western Cape, 2014)
Prostate cancer is a deadly disease that occurs in the male’s prostate gland. A prostate gland is a walnut structure that forms part of the male’s reproductive system. Prostate cancer is caused by high level than normal ...
Chemical and biological evaluation of palythoa tuberculosa collected from the red sea
(University of the Western Cape, 2015)
A chemical study on the total extract of the zoanthid Palythoa tuberculosa, collected
from the Red Sea, resulted in the isolation of seven polyhydroxylated sterols viz:
palysterols A-G, six of which are new. Their chemical ...
Graphene supported antimony nanoparticles on carbon electrodes for stripping analysis of environmental samples
(University of the Western Cape, 2015)
Platinum Group Metals (PGMs), particularly palladium (Pd), platinum (Pt) and rhodium (Rh) have been identified as pollutants in the environment due to their increased use in catalytic converters and mining in South Africa ...
Zeolite encapsulated metal complexes as heterogeneous catalysts for oxidation reactions
(University of the Western Cape, 2012)
This study describes the synthesis and characterisation of Cu(II) and V(IV) complexes of tri- and quadridentate ligands L1 and L2 formed by condensation of ethylenediamine with acetylacetonate in 1:1 and 1:2 molar ratio, ...
Nanoparticles-infused lithium manganese phosphate coated with magnesium-gold composite thin film - a possible novel material for lithium ion battery olivine cathode.
(University of the Western Cape, 2014)
Architecturally enhanced electrode materials for lithium ion batteries (LIB) with permeable morphologies have received broad research interests over the past years for their promising properties. However, literature based ...
