Polyamic acid-graphene oxide nanocomposite for electrochemical screening of antibiotic residues in water
(University of the Western Cape, 2015)
Pollution of water sources, aquifers and wetland systems caused by industry, agriculture, and municipally treated wastewater is a worldwide problem that contributes to the scarcity of clean and potable water. Rivers, ...
Electrochemical in-situ polymerization of graphene oxide/conducting star copolymer nanocomposite as supercapacitor electrode
(University of the Western Cape, 2017)
These days there are deep concerns over the environmental consequences of the rate of
consumption of energy from non-renewable sources because of the accelerated increase in greenhouse effect. There is, therefore, increasing ...
Polyanilino-graphene oxide intercalated with platinum group metal nanocomposites, for application as novel supercapacitor materials
(University of the Western Cape, 2014)
Supercapacitors are one of the important subjects concerning energy storage which has proven to be a challenge in this country. Currently, the electrodes of most commercial supercapacitor are made of carbon which is known ...
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 ...
Graphene based nano-coatings: synthesis and physical-chemical investigations
(UWC, 2012)
It is well known that a lead pencil is made of graphite, a naturally form of
carbon, this is important but not very exciting. The exciting part is that
graphite contains stacked layers of graphene and each and every layer ...
Graphene based materials for carbon capture
(University of Western Cape, 2020)
The adverse effects of CO2 and greenhouse gas emissions into the atmosphere is
believed to be one of the causes of climate change. The seriousness of global warming
is encouraging the development of technologies designed ...
Determination of paracetamol at the electrochemically reduced graphene oxide-metal nanocomposite modified pencil graphite (ERGO-MC-PGE) electrode using adsorptive stripping differential pulse voltammetry
(University of Western Cape, 2020)
This project focuses on the development of simple, highly sensitive, accurate, and low cost electrochemical sensors based on the modification of pencil graphite electrodes by the electrochemical reduction of graphene ...
Graphene-modified pencil graphite mercury-film electrodes for the determination of trace metals by cathodic adsorptive stripping voltammetry
(University of the Western Cape, 2018)
This project focuses on the simple, fast and highly sensitive adsorptive stripping voltammetry
detection of Nickel and Cobalt complexed with DMG and Nioxime respectively at a Reduced
Graphene Oxide modified pencil graphite ...
Spectroelectrochemical graphene-silver/zinc oxide nanoparticulate phenotype biosensors for ethambutol and pyrazinamide
(University of the Western Cape, 2019)
Tuberculosis (TB), a deadly disease second to HIV/AIDS, is a global health problem.
Diagnosis of active tuberculosis is tedious and requires expensive procedures since there is
no recognizable method for sole detection ...
Graphenated organic nanoparticles immunosensors for the detection of TB biomarkers
(University of the Western Cape, 2017)
Pulmonary Tuberculosis (TB) a disease second to HIV/AIDS is a global health problem that
arises in two states; as an active state and as a latent state. Diagnosis of active TB is tedious
and requires expensive procedures ...
