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 ...
Supercapacitor electrode materials based on nanostructured conducting polymers and metal oxides
(University of the Western Cape, 2013)
Supercapacitors are charge-storage devices. Compared to batteries, they have higher power density, more excellent reversibility and longer cycle life. Therefore, supercapacitors have played an increasingly important role ...
Fabrication of type-I indium-based near-infrared emitting quantum dots for biological imaging applications
(University of the Western Cape, 2013)
Semiconductor nanocrystals or quantum dots (QDs) are fluorescent nanometer-sized particles
which have physical dimensions that are smaller than the excitonic Bohr radius, large surface
area-to-volume ratios, broad ...
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, ...
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 ...
Polyamic acid composites for multiiple sensing applications in complex sample matrices
(2013)
Polyamic acid-polypyrrole (PAA/PPy) composite films were prepared and characterised for the use as conducting platforms in the design of biosensor systems. The thin films were synthesised by electrochemical method from a ...
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, optical and morphological characterization of pbse quantum dots for diagnostic studies: a model study
(University of the Western Cape, 2013)
In this study PbSe quantum dots (QDs) were successfully synthesized via the organometallic and aqueous routes. Optical characterization was carried out using photoluminescence (PL) spectroscopy, structural and morphological ...
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 ...
