Brine treatment using natural adsorbents
(University of the Western Cape, 2011)
The current study investigated application of natural adsorbents in brine treatment. Brines are hypersaline waters generated in power stations and mining industries rich in Mg2+, K+, Ca2+, Na+, SO4 2- , Cl- and traces of ...
Synthesis and characterizations of nanostructured MnO2 electrodes for supercapacitors applications
(University of the Western Cape, 2010)
The objective of this research was to develop highly efficient and yet effective MnO2 electrode materials for supercapacitors applications. Most attention had focussed on MnO2 as a candidate for pseudo-capacitor, due to ...
Degradation of persistent organic pollutants (pharmaceuticals & dyes) by combined dielectric barrier electrohydraulic discharge system and photo catalysts
(University of the Western Cape, 2019)
Water pollution problems have continued to increase not only in South Africa but worldwide due to human activities. The presence of organic toxins and bacteria in water sources is mostly due to population growth, industrial ...
Carbon supported aluminium trifluoride nanoparticles functionalized lithium manganese oxide for the development of advanced lithium ion battery system
(University of the Western Cape, 2017)
A novel lithium ion (Li-ion) battery cathode material has been investigated for potential mobile
technology energy storage applications. I have successfully synthesized Lithium Manganese oxide
(LMO), reduced Graphene Oxide ...
Chromium and Titanium based Stannum Nanocomposites materials as electron acceptors for next generation bulk Heterojunction photovoltaic cells
(University of the Western Cape, 2018)
Renewable energy has become the centrepiece of research in resolving the energy
crisis. One of the forms of renewable energy is solar energy. This form of energy is
costly to develop. Organic molecules are promising materials ...
Synthesis of sulphonated and transition metal oxide doped polymeric nanocomposites for application in design of supercapacitors
(University of the Western Cape, 2011)
To meet a fast-growing market demand for next generation portable electronic devices with higher performance and increased device functionalities, efficient electrical energy devices with substantially higher energy, power ...
Hydrophilic Polysulfone-Hydrogel Membrane Material for Improved Nanofiltration in Wastewater Treatment
(University of the Western Cape, 2013)
Over the last decade polysulfone membranes have been demonstrated to be one
of the best membrane types in wastewater treatment, especially in ultrafiltration,
owing to its mechanical robustness, structural and chemical ...
Highly selective mesoporous sorbents for mercury removal from industrial wastewater
(University of the Western Cape, 2011)
The results of this study show that novel mesoporous carbons were obtained as inverse replica of SBA-15, HMS and MCM-41 silica templates, with a large pore diameter (2-4 nm), a BET surface area of 1867, 874 and 910 m2g–1 ...
Synthesis and electrochemistry of novel conducting dendrimeric star copolymers on poly(propylene imine) dendrimer
(University of the Western Cape, 2011)
One of the most powerful aspects of conducting polymers is their ability to be nanostructured through innovative, synthetically manipulated, transformations, such as to tailor-make the polymers for specialized applications. ...
Advanced oxygen reduction reaction catalysts/material for direct methanol fuel cell (dmfc) application
(University of the Western Cape, 2014)
Fuel cells are widely considered to be efficient and non-polluting power source offering much higher energy density. This study is aimed at developing oxygen reduction reactions (ORR) catalysts with reduced platinum (Pt) ...
