The effects of capping agents on the synthesis of magnetic-luminescent Fe₃O₄ -InP/ZnSe nanocomposite material
(University of the Western Cape, 2015)
Magnetic luminescent nanoparticles of an iron oxide (Fe₃O₄) superparamagnetic core and an indium phosphide/zinc selenide (InP/ZnSe) quantum dot shell are reported. The magnetic nanoparticles (MNP’s) and quantum dots (QD’s) ...
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 ...
Nanocomposite-graphene based platform for heavy metal detection
(University of the Western Cape, 2010)
This study reports the synthesis of graphene by oxidizing graphite to graphite oxide using H2SO4 and KMnO4 and reducing graphene oxide to graphene by using NaBH4. Graphene was then characterized using FT-IR, TEM, AFM, XRD, ...
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 ...
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 ...
Electrochemical deposition of Graphene Oxide- metal nano-composite on Pencil-Graphite Electrode for the high sensitivity detection of Bisphenol A by Adsorptive Stripping Differential Pulse Voltammetry
(University of the Western Cape, 2018)
Electrochemical platforms were developed based on pencil graphite electrodes (PGEs) modified
electrochemically with reduced graphene oxide metal nanoparticles (ERGO–metalNPs) composite
and used for the high-sensitivity ...
Scalable synthesis of innovative silicon/carbon nanocomposite for next generation lithium-ion battery anodes
(University of the Western Cape, 2022)
Silicon is the most promising lithium-ion battery (LIB) anode due to its ultra-high capacity
(4200 mAh/g), which is 10 times greater than commercially available graphite anodes (372
mAh/g). Utilizing this large capacity ...
Carbon dot – polythionine nanocomposite sensor for the remediation of antibiotics in water
(University of the Western Cape, 2022)
Antibiotics are a necessary part of the world today where their main purpose is to
counter bacteria and diseases. Antibiotics are used in many areas which include
apiculture, domestic, livestock and medically. Since ...
