Graphene-modified pencil graphite bismuth-film electrodes for the determination of heavy metals in water samples using anodic stripping voltammetry
(University of the Western Cape, 2013)
Electrochemical platforms were developed based on pencil graphite electrodes (PGEs) modified with electrochemically deposited graphene (EG) sheets and Nafion-graphene (NG) nanocomposites in conjunction with an in situ ...
Metal nanoparticle modified polysulfone membrane for water treatment
(University of the Western Cape, 2013)
Membrane separation processes have been widely applied in the treatment of wastewater with polysulfone (PSF) polymer membrane being the most frequently used in ultrafiltration of wastewater due to its chemical and structural ...
Synthesis & characterization of yttria-stabilised zirconia (YSZ) hollow fibre support for Pd based membrane
(University of the Western Cape, 2013)
Inorganic based membranes which have a symmetric/asymmetric structure have been produced using an immersion induced phase inversion and sintering method. An organic binder solution (dope) containing yttria-stabilised ...
Novel adamantane derivatives as multifunctional neuroprotective agents
(University of the Western Cape, 2013)
The pathology of neurodegenerative disorders involves multiple steps, and it is probably for
this reason that targeting one particular step in a multi-step process has only yielded limited
results. Nitric oxide (NO) is ...
Multilayer graphene modified metal film electrodes for the determination of trace metals by anodic stripping voltammetry
(2013)
In this study multilayer graphene nanosheets was synthesize by oxidizing graphite to graphene oxide using H2SO4 and KMnO4 followed by reduction of graphene oxide to graphene using NaBH4. The graphene nanosheets were ...
The synthesis and electrochemical studies of chalcones and flavanones: an investigation of their antioxidant activity
(University of Western Cape, 2013)
Flavonoids, one of the biggest classes of secondary metabolites, are found abundantly in
nature in a broad range of fruits, vegetables and beverages such as tea, coffee, beer, wine and fruit drinks. Flavonoids have been ...
The response dynamics of indium telluride quantum dots impedimetric genosensor for telomerase cancer biomarker
(2013)
Cancer, the second most common cause of death after heart disease, is a complex and multifactorial disease that up to date is still under extensive research. To achieve early detection of cancer disease the discovery of ...
Supported metal catalysts for friedel-crafts alkylation
(2013)
The research focused on the synthesis, characterisation and activity of zeolite supported metal catalysts for the Friedel-Crafts alkylation of benzene with t-butyl chloride. Alkyl benzenes are traditionally produced via ...
Preliminary investigation of the natural contamination of agricultural crops with selected mycotoxins in northern rural South Africa (Limpopo and Mpumalanga Provinces)
(University of Western Cape, 2013)
Subsistence farmers may contribute significantly to food production, food
security, and employment in South Africa. However poor storage practices and
contamination with mycotoxins, particularly fumonisins and aflatoxins ...
