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 ...
Immunosensors developed on clathrate platform compounds
(University of the Western Cape, 2013)
Organic noncyclic compounds were used in the development of immunosensor for rapid fish species detection. Flourene derivatives show unique chemical and physical properties because they contain a rigid planar biphenyl unit, ...
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 ...
Electrochemical and optical modulation of selenide and telluride ternary alloy quantum dots genosensors
(University of the Western Cape, 2012)
Electroanalytical and optical properties of nanoscale materials are very important for biosensing applications as well as for understanding the unique one-dimensional carrier transport mechanism. One-dimensional semiconductor ...
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 ...
Lithium manganese oxide modified with copper-gold nanocomposite cladding- a potential novel cathode material for spinel type lithium-ion batteries
(University of the Western Cape, 2014)
Spinel lithium manganese oxide (LiMn2O4), for its low cost, easy preparation and nontoxicity, is regarded as a promising cathode material for lithium-ion batteries. However, a key problem prohibiting it from large scale ...
Synthesis and characterization of pt-sn/c cathode catalysts via polyol reduction method for use in direct methanol fuel cell
(2013)
Direct methanol fuel cells (DMFCs) are attractive power sources as they offer high conversion efficiencies with low or no pollution. One of the major advantages DMFCs has over PEMFCs is that methanol is a liquid and can ...
The chemical and biological characterization of South African helichrysum species
(University of the Western Cape, 2015)
South Africa has immensely rich natural flora diversity with more than 20 000 species of higherplants. Asteraceae is one of the biggest families of flowering plants with about 246 genera and 2,300 species in southern Africa. ...
The composition of photocatalytic nanofibres through electrospinning
(University of the Western Cape, 2014)
The aim of this study was to enrich electrospun fibres with the active mineral
phase TiO2 nanoparticles and then to evaluate how well the composite fibres
performed in the photocatalytic degradation of methylene blue ...
