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, ...
Investigation of anti-cancer potential of Pleiocarpa pycnantha leaves
(University of the Western Cape, 2013)
The Apocynaceae family is well known for its potential anticancer activity. Pleiocarpamine isolated from the Apocynaceae family and a constituent of Pleiocarpa pycnantha has been reported for anti-cancer activity. Prompted ...
Silver-coated polyethene terephthalate membrane for detection of pharmaceuticals using surface-enhanced Raman spectroscopy
(University of the Western Cape, 2017)
Surface-enhanced Raman spectroscopy (SERS) has emerged as one of the
analytical tools for detection of micro pollutants in the aquatic environment. The
SERS technique is touted to have fingerprinting capability, specificity, ...
Nano silver-iron-reduced graphene oxide modified titanium dioxide photocatalyst for the remediation of organic dye in water systems
(University of the Western Cape, 2018)
Drinking water with high concentrations of inorganic and organic contaminants can cause
adverse health defects. Specifically methyl orange dye is an organic water contaminant that has
been known (along with others like ...
Fabrication of luminescent nanocomposites for diagnosis of breast cancer
(University of the Western Cape, 2016)
In this study we were able to synthesize separately iron oxide magnetic nanoparticles, InP/ZnSe
and CdTe/ZnS quantum dots. The iron oxide nanoparticles were coupled with InP/ZnSe QDs to
form the luminescent magnetic ...
Factors influencing fuel cell life and a method of assessment for state of health
(University of the Western Cape, 2018)
Proton exchange membrane fuel cells (PEMFC) converts chemical energy from the electrochemical reaction of oxygen and hydrogen into electrical while emitting heat, oxygen depleted air (ODA) and water as by-products. The ...
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 ...
Re-use of South African fly ash for CO2 capture and brine remediation.
(University of the Western Cape, 2013)
Coal combustion accounts for 95% of electricity generation in South Africa while globally coal combustion for energy generation stands at 42%. It has been predicted that coal utilization for energy generation will continue ...
Application of Sutherlandia flutescens in cosmetic skin industry (phytochemical fingerprinting and its activity against skin immune diseases.
(University of the Western Cape, 2019)
Hyperpigmentation disorders such as melasma, freckles and black-pigmented spots on the
surface of the skin are often a result of increased over production and accumulation of melanin
pigments in the skin. In melanin ...
Brine treatment using natural adsorbents
(University of the Western Cape, 2011)
Studies involving the use of natural clays such as bentonite, montmorillonite and natural zeolite clinoptilolite in water treatment have been reported. Researchers suggested cost effective processes, such as ion-exchange ...
