Production and high temperature treatment of syngas.
(2010)
Gas cleaning is an essential step in many chemical processes. The reason for cleaning is to remove components that can damage equipment or inhibit further reactions. The treatment can include the removal of particulates, ...
Layered double hydroxides : synthesis and application in gene delivery to mammalian cells in culture.
(2010)
Layered double hydroxides (LDHs) or hydrotalcite-like compounds (HTLcs) are classified as anionic clays in which their structure is based upon brucite and are represented by the following general chemical formula:
[MII1-xMIII ...
Characterisation and quantification of wood extractives and their impact on pitch.
(2011)
The aims of this study were to characterise and quantify wood extractives in E. grandis and E.
nitens and determine the impact of wood extractives on pitch formation. Initially a comparison
was made with individual solvent ...
Ozone initiated oxidation of organic pollutants, m-xylene and 2-chloroethanol.
(2010)
A variety of hazardous organic compounds are present in leachate from landfill sites that accept medical and industrial chemical waste. Most of these compounds find their way into nearby streams, rivers and dams, posing a ...
The synthesis and application of heteroatom boralanes containing nitrogen, oxygen and sulfur.
(2013)
There is a constant need for robust and highly reactive hydroborating reagents which will be able to yield stable organoborane compounds upon their hydroboration with olefins. These stable organoborane compounds can be ...
Synthesis and characterisation of novel oxovanadium(IV) Schiff base complexes: A study of their electronic spectral properties, peroxide binding affinities, DFT-calculated geometries and spectra, and cytotoxicity towards human carcinoma cells.
(2012)
A series of five, tetradentate Schiff-base ligands were synthesised and chelated to vanadyl to form
oxovanadium(IV) complexes. The ligands, 4,4’-{benzene-1,2-diylbis[nitrilo(1E)phen-1-yl-1ylidene]}-
dibenzene-1,3-diol ...
Phytochemical and anti-drepanocytosis studies of Cajanus cajan, Callistemon viminalis, Melaleuca bracteata var. Revolution Gold and Syzygium guineense.
(2010)
All over Africa, traditional healers use medicinal plants to prepare medicines to treat a
wide range of illnesses. One of these illnesses is sickle cell anaemia or drepanocytosis
or sicklemia. This disease is particularly ...
The isolation, structure elucidation and biological testing of compounds from Plectranthus hadiensis.
(2010)
Three diterpenes of the abietane class, 7b-acetoxy-6b-hydroxyroyleanone (I), 6b,7b-
dihydroxyroyleanone (II) and ent-pimara-8(14),15-diene-3b,11a-diol (III) and three
triterpenes, 2a,3a,19 -trihydroxyurs-12-en-28-oic ...
Synthesis and characterization of gold (I) complexes of bis(diphenylphosphino)-acetonitrile.
(2010)
This study comprised the synthesis and characterization of select phosphine ligands and their
complexation to gold(I). An initial approach was the reaction between Ph2PCl in "wet" organic
solvent and [ClAu(tht)] (tht = ...
Tuning the reactivity of mononuclear tridentate platinum (II) complexes : a detailed kinetic and mechanistic approach using Azole Nucleophiles.
(2014-09-04)
The kinetic substitution reactions of two different sets of mononuclear Platinum(II) complexes with heterocyclic bio-relevant azole nucleophiles, viz. Imidazole (Im), 1-methylimidazole (MIm), 1,2-Dimethylimidazole (DIm), ...
