A kinetic and mechanistic study into the substition behaviour of Plantinum (II) Polypyridyl complexes with a series of Azole Ligands.
(2010)
A novel platinum(II) complex, [Pt{4-(o-tolyl)-6-(3˝-isoquinoyl)-2,2´-bipyridine}Cl]SbF6 (Pt4) was synthesized and characterised by means of infrared, elemental analysis, mass spectroscopy, and NMR spectroscopy.
Substitution ...
The preferential oxidation of CO nickel oxide catalysts and the doping effects of platinum in hydrogen rich streams.
(2012)
Hydrogen has now become a suitable candidate for alternative energy generation for small
scale applications with the aid of fuel cells. On-board production of hydrogen from methane
is the most preferred method via a ...
Supported copper oxide catalysts for octanal hydrogenation : the influence of water.
(2010)
Copper oxide supported on alumina (CuO/Al2O3), silica (CuO/SiO2) and chromia
(CuO/Cr2O3) have been synthesized and characterized. These catalysts were
characterized using XRD, SEM, TEM, ICP, BET surface area and pore ...
Synthesis and characterization of new gold and silver complexes based on P/N and P/S ligands : P/S ligand-stabilized gold nanoparticles.
(2013)
This dissertation comprises three distinct studies, two of which concerns molecular inorganic chemistry, and one concerns inorganic materials science.
Firstly, the synthesis and characterization of new dithiophosphonate ...
An investigation of a heterogeneous aminohydroxylation catalyst.
(2010)
Os-Zn-Al hydrotalcite-like compounds (HTlc’s) were synthesised by the co-precipitation method
and characterised using different techniques (powder XRD, ICP-OES, FT-IR spectroscopy,
BET-surface area measurements, SEM and ...
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 ...
Studies on the nutritional value of the oils and mesocarp of avocado (Persea americana) and impact of soil quality on elemental composition.
(2011)
This study covered both the Hass and Fuerte varieties of avocado pears. The quality of
extracted avocado oil produced by different extraction techniques was assessed to determine
the effect the extraction method had on ...
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, ...
Synthesis, characterization and application of supported nickel catalysts for the hydrogenation of octanal.
(2010)
Three nickel based catalysts were prepared by the impregnation method (Ni/Al2O3 and Ni/SiO2)
and co-precipitation method (Ni/ZnO). The catalysts were characterized by XRD, ICP-OES,
BET-surface area and pore volume, SEM, ...
Phytochemical and elemental studies of two indigenous medicinal plants of South Africa, Bridelia micrantha and Sideroxylon inerme.
(2014)
Bridelia micrantha (Euphorbaceae) and Sideroxylon inerme (Sapoacaea) are two indigenous medicinal plants found in KwaZulu-Natal and are both known as ‘uMhlalamagwababa’ in isiZulu. These two plants species have similar ...
