A solution and solid state study of vanadium complexes
(University of the Free State, 2014-09-17)
English: Vanadium is an early first-row transition metal that is known for the beautiful coloured compounds that it forms in a wide range of oxidation states. In high oxidation states, vanadium is very oxophilic whilst ...
Method validation for the quantification of impurities in Zirconium metal and other relevant Zr compounds.
(University of the Free State, 2012-11)
English: Zirconium occurs in nature as a component of the lithosphere in various molecular fractions within a number of mineral ores. Since its discovery in 1789, many chemical processes have been developed to have ...
Computational, structural and electrochemical properties of metal (III) tris-betadiketonato complexes
(University of the Free State, 2012)
English: A series of MnIII(β-diketonato)3 complexes (β-diketonato = acac, ba, dbm, tfaa, tfth, tffu, tfba and hfac) were synthesized and characterized with the aid of mass spectroscopy, elemental analysis, X-ray diffraction ...
A solution and solid state study of niobium complexes
(University of the Free State, 2012-01)
English: This research project focused on the investigation and identification of various niobium(V) complexes containing selected O,O’-bidentate ligands that could potentially be used for the selective separation of ...
