2,4,6-Trichloro-1,3,5-triazine as a triorthogonal chemoselective linker.
(2019)Abstract available in PDF. -
Amino-, amido- and oxy-bipyridyl complexes of copper, ruthenium, molybdenum and rhodium.
(1996)The work described in this thesis concerns the synthesis and study of the coordination behaviour of the 6-anilino-2,2'-bipyridyl (Habipy), 6-N-methylanilino-2,2'-bipyridyl (mabipy), 6-piperidyl2,2'.- bipyridyl (pipbipy) ... -
Amperometric determination of selected persistent organic pollutants and heavy metals using horseradish peroxidase biosensor.
(2010)Persistent organic pollutants and heavy metals are released into the environment through different anthropogenic processes. They are of concern because they tend to bioaccumulate in the food chain and show adverse health ... -
The analysis of organometallic compounds using SFC-ICPMS.
(1994)Supercritical fluid chromatography has recently been coupled to an ICPMS detector. The method has been shown to be suitable for the speciation and analysis of organometallic compounds at trace levels. This study ... -
An analysis of Sappi Saiccor's effluent streams.
(2003)SAPPI SAICCOR is a pulp and paper mill situated in Umkomaas, 50 kms south of the port of Durban in South Africa. It was the first company to produce high grade dissolving pulp from the Eucalyptus tree and is currently the ... -
Analysis of targeted pharmaceuticals and metabolites at a wastewater treatment plant in KwaZulu-Natal, South Africa.
(2022)Globally, surface water bodies are shown to be severely contaminated by chemical compounds as a result of human activity. Some of these compounds are inclusive of pharmaceuticals and their metabolites which are classified ... -
Analytical and biochemical studies of selected seaweeds obtained from the eastern coast of South Africa`s Indian Ocean in KwaZulu-Natal.
(2015)Abstract available in PDF file. -
Antidiabetic compounds from Hypoxis colchicifolia and Terminalia sericea.
In this project two medicinal plant species, namely Hypoxis colchicifolia Bak (Hypoxidaceae) and Terminalia sericea Burch. (Combretaceae), have been investigated and different compounds isolated and characterised. The aim ... -
Antioxidant activity of Maillard reaction products.
(1994)The use of natural antioxidants to improve the oxidative stability of food lipids has received special attention because of the worldwide trend to avoid the use of synthetic food additives. A wide range of natural sources ... -
Application of analytical chemistry and waste minimisation techniques in a paint drier plant.
(2009)Environmental sustainability, strict Municipal bylaws, ever-increasing waste disposal -
Application of analytical chemistry to waste minimisation in the powder coating industry.
(2005)A local company instituted a new chemical procedure in their spray phosphating system used in the pretreatment of large components for industrial racking systems. An inorganic conversion coating is deposited on the ... -
Application of chemical analysis as an aid to waste minimisation in the electroplating industry.
(2009)A chromium plating line used by a local company was monitored to identify any potential waste minimisation opportunities. Plating of the workpiece surface is carried out by immersing the workpiece in seven process (treatment) ... -
Application of cobalt complexes containing SNS ligands as catalysts for biomimetic paraffin activation.
(2012)A series of SNS ligands have been successfully synthesised and characterised by IR, NMR and MS. The ligands are divided into two groups and represented by the general formulae: 2,6- bis(RSCH2)pyridine [R= methyl, ethyl, ... -
Application of metallocenes for the synthesis of multiwalled carbon nanotubes.
(2016)Abstract available in PDF file. -
An application of modern analytical solution techniques to nonlinear partial differential equations.
(2014)Many physics and engineering problems are modeled by differential equations. In many instances these equations are nonlinear and exact solutions are difficult to obtain. Numerical schemes are often used to find approximate ... -
Application of N-doped TiO₂/Bi₂O₃/rGO nanocomposites as a photoanode material in dye- sensitized solar cells.
(2021)Abstract available in PDF. -
Application of the Noyori annulation reaction to the cephalotaxine spirocycle.
(2001)Cephalotaxine is a naturally occurring alkaloid which is the structural motif of a number of compounds which have shown promising anti-cancer properties. This fact together with its relatively complex pentacyclic structure, ... -
Application of triazolium-based metal complexes for catalytic oxidation of octane.
(2014)A series of related 1,2,3-triazole compounds were synthesised and characterised by spectroscopic methods including NMR, IR, MS and X-ray diffraction. N-alkylation of the triazole compounds yielded 1,4-disubstituted triazolium ... -
An approach to the synthesis of chiral carbamates.
(1996)An attempt to obtain chiral induction across the carbamate linkage (-NCOO-), using chiral amines and the benzyl carbamate, was embarked upon. Initial studies centred around the benzyl carbamate protected form of ...
