Phytochemical investigation and biological studies of some South African plant species (Asteraceae and Hyacinthaceae)
(2021)Plants used in conventional medicine for the treatment of different ailments have been the bedrock for modern therapeutics. Scilla nervosa from the Hyacinthaceae family and Helichrysum panduratum and Helichrysum actutaum ... -
Synthesis, characterization and evaluation of ionic liquids and polymeric ionic liquids/functionalized multiwalled carbon nanotubes for Cr(VI) adsorption.
(2019)In this study, a series of imidazolium and pyridinium-based ionic liquids (ILs), polymeric ionic liquids (PILs), and their carbon nanotubes-functionalized composites were synthesized, characterized and applied as potential ... -
Synthesis structural and optical studies of copper sulphide and silfide nanoparticles from Cu(II) and Ag(I) dithiocarbamate single source precursors.
(2018)Eight dithiocarbamate ligands were synthesized from butylamine, diallylamine, N-ethyl aniline, N-methyl benzyl amine, piperidine, morpholine, dibenzyl amine and phenyl piperizine. Eight copper(II) dithiocarbamate complexes ... -
Synthesis of nitrogen-, oxygen- and phosphine- donor palladium(II) complexes for the catalytic hydrogenation and methoxycarbonylation of alkenes and alkynes.
(2019)Reactions of N-(1H-benzoimidazol-2-ylmethyl-2-methoxy)aniline (L1) and N-(1H-benzoimidazol-2-ylmethyl-2-bromo)aniline (L2) with p-TsOH, Pd(AOc)2 and two equivalents of PPh3 or PCy3 produced the corresponding palladium ... -
An instrumental evaluation of selected metal functionalised semiconductors in the facilitation of photo-organic transformations.
(2019)Throughout this research study, various strategies to design, synthesise and test the photo-reactivity of attenuated wide band gap semiconductors in alcohol oxidation studies have been explored. An alizarin red-sensitised ... -
The rates and mechanisms of substitution from Ru(II) complexes with different non-leaving ligand environments.
(2019)Results from multiple studies have confirmed that the nature of ligands on the metal centre determines the properties of an anti-cancer agent in a biological environment. Ligands affect solubility, substitution reactivity, ... -
Understanding the reactivity of ruthenium (II) complexes kinetics and mechanistic studies.
(2019)Abstract available in pdf. -
The control, manipulation and detection of surface plasmons and cold atoms.
(2017)Cold atoms and surface plasmons are now widely recognised as having a vast potential as sources for future quantum information technologies, including in quantum simulations, quantum computing and quantum-enhanced ... -
Controlling the reactivity of mononuclear palladiun (II) complexes. Substitution kinetics and mechanisms.
(2019)Abstract available in PDF. -
A study of modified mesoporous silica for the adsorption of selected organic pollutants.
(2016)Water is an essential natural resource the world over. Only one-tenth of the world’s water is pol-lution free and hence there is a need for remediating polluted water. These pollutants, some of which are organic (dyes and ... -
Phytochemical investigation and tissue culture studies on the South African knob trees, Zanthoxylum Capense and Senegalia Nigrescens.
