Oxidovanadium complexes with N-donor heterocyclic chelates.
(2014-02-12)
The growing significance of vanadium in medicinal inorganic chemistry is due to the diverse
biological activities of its metal complexes, as elaborated in Chapter 1. These biological
activities stem from the fact ...
The catalysed activation of n-octane over iron modified hydroxyapatites.
(2014)
This research effort investigated the activation of n-octane by oxidative dehydrogenation and
dehydrogenation over iron substituted and iron supported on hydroxyapatite catalysts. Pure
hydroxyapatite and iron substituted ...
The synthesis of xanthene-based transition metal complexes and their application in the oxidation reaction of n-octane.
(2014)
The oxidation of alkanes into valuable products such as alcohols, ketones and aldehydes is very
important to industry for detergents and perfumes. One of the challenges with alkanes is their
inertness which results from ...
Identification and quantification of chelidonic acid and other ligands with potential for Ni uptake in the hyperaccumulator, Berkheya coddii.
(2014)
B. coddii is a known nickel hyperaccumulator, a plant that is able to take up high levels of Ni (< 37 000 mg kg -1) without exhibiting toxic effects. It grows in serpentine soil and is endemic to the Barberton Region, ...
Enantioselective synthesis of 1-substituted tetrahydroisoquinolines.
(2014-09-15)
Many organic compounds are chiral and they are useful because of the biological
activities associated with them. The biological activities of chiral compounds are often
linked to absolute configuration, i.e. a compound ...
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.
(2014-04-07)
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 ...
Novel ruthenium (ll/lll) complexes with multidentate Schiff base chelates containing biologically relevant moieties.
(2014)
The discovery of novel ruthenium metallopharmaceuticals is highly dependent on its
coordination chemistry. As emphasized in Chapter 1, the biodistribution pathway of
a potential ruthenium metallopharmaceutical depends ...
The influence of physicochemical reaction parameters on the synthesis of multi-walled carbon nanotubes for use as catalyst supports.
(2012)
Multi-walled carbon nanotubes (MWCNTs) and other shaped carbon nanomaterials (SCNMs) were
synthesized by the floating catalyst chemical vapour deposition (CVD) method, using either
ferrocene [1] as the catalyst at 2.5 ...
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 ...
