▼ On a per capita basis, cement is the second most widely consumed product in the world and its demand is increasing globally due to population growth and urbanisation. Manufacturing plants produce cement kiln dust (CKD) as one of the by-products while coal provides the dominant energy source in the manufacturing process. Various meta ls are found in CKD and some of these are micro nutrients with potentially toxic effects. If these are present in large quantities, they pose a direct threat to vegetation, animals and humans. The aim o f this study was to quantify a selected number of trace metal concentrations in vegetation, soil , dust and water samples near a cement manufacturing pl ant in the North West Province. Thirty-one samples at various distances from approximately 500m to 2700m from where the cement factory is situated, were collected. In addition, similar samples (except for water) were taken from a control site situated 72 kilometres in a north-western direction from the factory. The water control sample was collected from the Ditsobotla municipal water supply. Soil. plant and dust samples as well as the sediment from the water sample were acid digested to obtain total metal concentrations . The acid digested samples were analyzed for selected metal concentrations using the ICP-MS. The relationship between soil metal concentrations and particle size distribution as well as the relationship between dust concentrations and Ca concentrations was established to determine the link with the presence on a CMP in the area. The control samples, reference standards and results from similar research performed were used to compare with metal concentrations found in this study. The study revealed that Ni and Cu concentrations are higher in the silt fraction of the soil whilst V, Co, Zn and Pb in the silt fraction are only marginally higher than the complete soil sample. Only Cr and Mn concentrations were higher in soil samples than the control and reference values, while metal concentrations for Cr, Cu, Pb and Mn were higher in the dust samples than the control and the Emission Limit Value (EL V). Moreover, metal concentrations in the vegetation samples are not a concern as the concentrations a re lower than reference values. Cadmium and As levels are of no concern in this study area especially since dust samples had undetectably low levels. The condition of the environment m relation to pollution from the cement factory was established. Although some metals revealed lower concentrations, the study demonstrated the potential of metal contamination particularly Ni, Mn and Cr to the environment vis-a vis on the surrounding vegetation, animals and possibly on humans. It was therefore recommended that ELV limits for South Africa should be established and monitored for cement factories in South Africa coupled with sustainable land management policies.

▼ World wide urban rivers are the most utilised and degraded. A variety of everyday sources of metal pollution exist that is entrenched in the modern way of life. Lately there has been a tremendous growth in the establishment and development of human settlements, both formal and informal in the Cape Town area. The surroundings of the Kuils River are not excluded from this. There are various communities in close proximity to the Kuils River. Due to this, more industries are also being established. This has caused an increased production of potential environmental pollutants, including metals. The aim of the study was firstly, to identify potential sources of metal pollution along the entire length of the Kuils River, in order to identify sampling sites. Secondly, to identify the metals contaminating the water and sediment of the Kuils River. Thirdly, to determine the bioaccumulation of metals in freshwater snails (Physa ecuta). Four sampling sites were identified along the Kuils River. Freshwater snails (P. acuta), sediment and water were collected every 2 months for a period of one year. The following metals were investigated: Aluminium (AI), Cadmium (Cd) Cobalt (Co), Chromium (Cr), Copper (Cu), Iron (Fe), Lead (Pb), Manganese (Mn), Nickel (Ni.) and Zinc (Zn). Samples were digested with 55% nitric acid. The Inductively Coupled Plasma - Atomic Emission Spectrometer (ICP-AES) were used for metal analyses. The results were statistically analysed by means of ANOVA on ranks using the Sigmastat statistical package. Results revealed that most metals found in water, sediment and snails had significantly higher concentrations at site 1. This is possibly due to input from the surrounding urban area and nearly agricultural activities. Water concentrations of AI, Cu, Mn and Zn were higher than the DWAF (1996) guidelines. Sediment was mostly contaminated with AI, Fe, Pb and Zn, while the snails contained significant levels of Cu, Fe, Mn and Zn. Further investigations involving toxicity testing should be conducted to determine the toxicity of these metals to (Physa acuta). Advisors/Committee Members: Odendaal, J. P (advisor), Snyman, R. G (advisor).

▼ Nanotwinned metals have exhibited enhanced mechanical properties, including ultra-high strength, good ductility and remarkable fracture toughness. In this dissertation, we used large-scale atomistic simulations to investigate deformation and fracture behaviors of nanotwinned metals, in forms of bulk, thin films and nanopillars. The work is organized in three parts. In the first part (Chapter 4), we performed large-scale atomistic simulations to study deformation mechanisms in equiaxed- and columnar-grained polycrystalline nanotwinned bulk Cu. Three dislocation-based mechanisms are revealed. In the equiaxed-grained nanotwinned Cu, it was found that dislocation cutting through or pileup on twin boundary (TB) is a controlling mechanism, leading to strength hardening. However, when TB spacing falls below a critical size, the strength softening governed by nucleation and motion of partial dislocations parallel to TBs was observed in our simulations. To characterize such twin size-mediated softening, we have proposed a scaling law (including two microstructural dimensions, i.e. mean grain size and TB spacing) based on kinetic theory of dislocation nucleation. For columnar-grained nanotwinned Cu, when the tensile axis is parallel to TBs, the movement of threading dislocations confined inside twin lamellae dominates plastic deformation. The second part (Chapter 5) is dedicated to interpret a novel toughening mechanism (crack bridging) observed in in-situ experiments on nanotwinned Cu thin films. Atomistic simulations showed that during plastic deformation, initially clean TB can transform to a dislocation wall which can block further dislocation activity and resist crack propagation, leading to experimentally observed crack-bridging behavior, i.e. nanoscale twins serve as uncracked ligaments. The formation of dislocation wall is attributed to interaction between dislocations emitted from crack tip and TBs. The third part (Chapter 6) is devoted to investigate mechanical responses of nanotwinned Cu nanopillars with different TB orientations. Atomistic simulations showed that the strain localization (such as necking or shear banding) is a governing deformation mechanism in nanotwinned nanopillars with orthogonal TBs, while the detwinning dominates plastic deformation of nanopillars with slanted TBs. The difference in deformation mechanisms leads to substantially different strengths in corresponding nanopillars. Atomistic simulations also demonstrated that TB-surface intersection is a preferential dislocation nucleation site in nanopillars with different TB orientations.

▼ The ligands di(2-pyridyl) ketone (DPK) and cis-1,2 di(2-pyridyl) ethylene (DPE) are N,N,Odonor ligands that can undergo nucleophilic addition and become more flexible for coordination. The reaction between the lanthanide thiocyanate salt and DPK gave rise to seven novel complexes of the general formula [Ln(NCS)3(DPKOH)3], where Ln = La, Ce, Nd, Eu, Tb, Dy and Ho. 1H NMR spectroscopy verified that the ligand underwent nucleophilic addition upon coordination. This was further confirmed using UV-Vis spectroscopy which showed a shift in the absorption bands due to conjugation of electrons within the pyridyl ring upon coordination. UV-Vis spectroscopy was also utilised to test the covalent character of the neodymium and holmium complexes. X-ray diffraction and IR spectroscopy showed that three DPK ligands coordinated bidentately through a pyridinic nitrogen and a hydroxyl oxygen, while three isothiocyanato molecules completed the coordination environment around each metal. Furthermore, X-ray diffraction also revealed that these complexes are isostructural, ninecoordinate and the polyhedron which encloses each ion is of trigonal tricapped prismatic shape with D3h symmetry. Micro-analysis on all the complexes, except lanthanum and holmium confirmed the molecular formulae produced from the crystallographic data of each complex. The reaction between the lanthanide thiocyanate salt and DPE produced poor quality crystals which could not be detected by X-ray diffraction. The lanthanide salts used for this reaction were lanthanum, neodymium, europium, dysprosium and holmium. Upon coordination, conductivity measurements detected the presence of lanthanide ions in each solution. 1H NMR and IR spectroscopic studies showed that the ethylenic moiety of DPE underwent nucleophilic addition upon coordination. UV-Vis spectroscopy further confirmed nucleophilic addition upon coordination due to shifts in absorption bands. IR spectroscopy verified the possibility of a bidentate coordination to each metal through a pyridinic nitrogen and a hydroxyl oxygen as well as a monodentate coordination through isothiocyanato ligands. A micro-analysis on all the complexes provided the molecular formulae that can best fit each complex. The effect of the solvent molecules on the bonding parameters of the lanthanum complex was investigated. An analysis of the results produced from crystallographic data revealed the presence of intermolecular forces which interacted and stabilised the complex.

▼ The reactions of Ln(NO3)3∙6H2O (Ln = Pr, Nd or Er) with the potentially tridentate O,N,O chelating ligand 2,6-pyridinedimethanol (H2pydm) were investigated, and complexes with the formula, [Ln(H2pydm)2(NO3)2](NO3) (Ln = Pr or Nd) and [Er(H2pydm)3](NO3)3 were isolated. The ten-coordinate Pr(III) and Nd(III) compounds crystallise in the triclinic space group P-1 while the nine-coordinate Er(III) complex crystallises in the monoclinic system (P21/n). The reaction of PrCl3∙6H2O with H2pydm yielded the compound, [Pr(H2pydm)3](Cl)3, that crystallises in the monoclinic system, space group P21/c with α = 90, β = 98.680(1) and γ = 90°. The nine-coordinate Pr(III) ion is bound to three H2pydm ligands, with bond distances Pr-O 2.455(2)-2.478(2) Å and Pr-N 2.6355(19)-2.64(2) Å. X-ray crystal structures of all the H2pydm complexes reveal that the ligand coordinates tridentately, via the pyridyl nitrogen atom and the two hydroxyl oxygen atoms. The electronic absorption spectra of complexes show 4f-4f transitions. Rare-earth complexes, [Ln(H2L1)2(NO3)3] [Ln = Gd, Ho or Nd], were also prepared from a Schiff base. The X-ray single-crystal diffraction studies and SHAPE analyses of the Gd(III) and Ho(III) complexes shows that the complexes are ten-coordinate and exhibit distorted tetradecahedron geometries. With proton migration occurring from the phenol group to the imine function, complexation of the lanthanides to the ligand gives the ligand a zwitterionic phenoxo-iminium form. A phenolate oxygen-bridged dinuclear complex, [Ce2(H2L1)(ovan)3(NO3)3], has been obtained by reacting Ce(NO3)3∙6H2O with an o-vanillin derived Schiff base ligand, 2-((E)-(1-hydroxy-2-methylpropan-2-ylimino)methyl)-6-methoxyphenol (H2L1). Hydrolysis of the Schiff base occurred to yield o-vanillin, which bridged two cerium atoms with the Ce∙∙∙Ce distance equal to 3.823 Å. The Ce(III) ions are both tencoordinate, but have different coordination environments, showing tetradecahedron and staggered dodecahedron geometries, respectively. The reaction of salicylaldehyde-N(4)-diethylthiosemicarbazone (H2L2) in the presence of hydrated Ln(III) nitrates led to the isolation of two novel compounds: (E)-2[(ortho-hydroxy)benzylidene]-2-(thiomethyl)-thionohydrazide (1) and bis[2,3-diaza4-(2-hydroxyphenyl)-1-thiomethyl-buta-1,3-diene]disulfide. The latter is a dimer of the former. For this asymmetric Schiff base, 1 and the symmetric disulfide, classical hydrogen bonds of the O–H∙∙∙N as well as N–H∙∙∙S (for 1) type are apparent next to C–H∙∙∙O contacts. 4-(4-Bromophenyl)-1-(propan-2-ylidene)thiosemicarbazide was also prepared upon reacting 4-(4-bromophenyl)-3-thiosemicarbazide with acetone in the presence of ethanol and La(NO3)3∙6H2O. The C=S bond length was found to be 1.6686(16) Å which is in good agreement with other thioketones whose metrical parameters have been deposited with the Cambridge Structural Database. Classical hydrogen bonds of the N–H∙∙∙N and the N–H∙∙∙Br type are observed next to C–H∙∙∙S contacts. All synthesised compounds were characterised by…

▼ During the creation of this work, I identified and acquired various contemporary objects relating to branding, consumerism, and fads. Through a process of artificial aging, ranging from abrading, cutting, and sandblasting to burying them in soil and chemical treatments of bleach, salt and ammonia, I made the objects appear as if they had been removed from an archeological site after centuries under ground. I incorporated these apparently ancient contemporary consumer items into new compositions using mostly silver and aluminum. These new objects are created using traditional metal-smithing techniques and bearing a resemblance to classicism in form as well. The designs reference ritual objects from a variety of world cultural and religious traditions combined with a retro-futurism science fiction aesthetic. By combining these new items that look old with fine metalwork that is classical but looks new I am creating an ambiguity of time, place, and tradition in order to transport the observer into a viewpoint that forces questioning of our own place in history. Like all science fiction literature or film, I am using the past and future to speak about contemporary issues. What I am interested in exploring is the functions and purpose of myth, ritual, and religion in past culture systems and identifying, in our modern world of science and reason that has been for centuries becoming increasingly secular, how it is that we have managed to fill the void created by the absence of the old rules. Whatever one chooses to call it, whether it is myth or ritual or religion, it has served an important functional role in the growth and sustainability of all cultural systems. These belief structures provided our ancestors (and many people still today) with a level of perceived objectivity, social cohesion and cooperation, order, stability, hierarchies, and a way to guide the members of cultural systems through the turmoil of birth, the pains of growing, the tension of adulthood, and finally through the mystery of death. What I am interested in identifying is what it is in our modern, secular cultural system that has filled the void created by secularization and replaced the old mechanism with new to provide similar functions. Through the process of ideation and creation of this body of work the major system I have identified as filling the role played previously by myth is that of consumerism, capitalism, and wealth. This question of the new mythic structure in the modern world is not a new question and I am not the first person to identify capitalism and its bi-products as filling this role, but through this body of work and its method of display I aim to bring the concept to a more literal and digestible examination.

▼ This thesis describes the synthesis and coordination chemistry of bicyclic phosphorus-nitrogen (PN) ligands containing the rigid and preorganised bicyclo[3.3.1]nonan-9-one framework. The PN ligands were prepared via the Mannich condensation reaction of four different phosphorinanone classes with amines and aldehydes. The phosphorinanone compounds, 2,6-dimethyl-3,5-diphenyl-4-phenyl-4- phosphacyclohexanone (isomers 50 and 51), 3,5-diphenyl-4-phenyl-4- phosphacyclohexanone (44, 45) and 4-phenyl-4-phosphacyclohexanone (42) were prepared by literature methods, whereas the isomers of 4-t-butyl-2,6- di(carbomethoxy) - 3,5 - bis(p - dimethylaminophenyl) - 4 - phosphacyclohexanone (53, 54) were synthesised by the reaction of ButPH2 with 2,4-di(carbomethoxy)- 1,5 - bis(p - dimethylaminophenyl)penta - 1,4 - dien - 3 - one (38). The Mannich reactions of phosphorinanones 50 and 51 were not successful, whereas the reactions of 44, 45 and 42 produced unidentifiable products. The reaction of phosphorinanone 53 with methylamine and formaldehyde produced the bicyclic PN compound 7-t-butyl-1,5-di(carbomethoxy)-6,8-bis(p-dimethylaminophenyl)- 3 - methyl - 3 - aza - 7 - phosphabicyclo[3.3.1]nonan - 9 - one (65). The identical Mannich reaction of phosphorinanone 54 also yielded 65, as well as the PN compound 4-t-butyl-6-carbomethoxy-5-(p-dimethylaminophenyl)- 2-methyl-2-aza-4-phosphacyclohexanone (66) and the E/Z isomers of 3-(p-dimethylaminophenyl)methyl-2-propenoate (67). The bicyclic PN ligand 65 adopts a chair-chair conformation in solution and the solid state as confirmed by X-ray crystallography. The coordination chemistry of this ligand was comprehensively explored with rhodium, palladium and platinum, and a wide range of complexes were synthesised including [ML2(65)] (M = Pd, Pt; L = Cl, Me), [ML(65)] (M = Rh, Pd, Pt; L = C2H4, cod, dba, norb) (cod = cycloocta-1,5-diene, dba = trans,trans- dibenzylideneacetone, norb = norborn-2-ene), [Pd(n3 -C3H5)(65)]X (X = Cl, SbF6) and [PtL(65)]CH(SO2CF3)2 (L = 1-o,4-5-n-C8H13, 1-3-n-C8H13). Cycloplatination at the ortho-position of the 6,8-dimethylaminophenyl sub- stituents was an interesting feature of the coordination chemistry of PN ligand 65. Ortho-metallation at both dimethylaminophenyl groups led to the formation of complex [Pt(C2H4)(65-2H)] (76), whereas metallation of only one aryl group produced the complex [Pt(C8H13)(65-H)] (87). Further reaction of complex 76 yielded the trans- and cis-hydroxo-bridged dimers [Pt2(u-OH)2(65-H)2] (98, 101). The nitrogen donor atom is not coordinated to the platinum metal centres in the cyclometallated PN complexes. Protonation of [Pt(C2H4)(65)] (75) with CH2(SO2CF3)2 produced the hydride complex [PtH{CH(SO2CF3)2}(65)] (92) and the agostic ethyl complex [Pt(C2H5)(65)]CH(SO2CF3)2 (93). Similarly, protonation of [Pt(norb)(65)] (74) with CHPh(SO2CF3)2 gave the norbornyl agostic complex [Pt(C7H11)(65)]CPh(SO2CF3)2 (94) as confirmed by X-ray crystallography. In addition, hydrated analogues of some of the coordination complexes of PN ligand 65 mentioned… Advisors/Committee Members: Spencer, John.

▼ This thesis incorporates reports of research on the development and application of innovative chemical and biochemical techniques to the study of mechanisms of metal toxicity m simple single-celled organisms and more complex multicellular organisms including humans. The thesis is based on research undertaken over the last 10 years and published m 26 refereed scientific papers Single-celled algae are the foundation of most aquatic food chains and account for much of the productivity of aquatic ecosystems Marine and freshwater algae are particularly sensitive to a wide range of metals and organic compounds, and their viability can be used as an indicator of environmental change. Chrome toxicity tests, based on algal growth and enzyme inhibition, have been developed and applied to assessments of the bioavailability and toxicity of metals in aquatic systems Specific applications of the algal bioassays for assessing mine-derived contaminants in natural systems has been described Knowledge of modes of action of different metal species at a sub-cellular level is essential to understanding and predicting the bioavailability and toxicity of metals in natural waters. Research on the mechanisms of toxicity of copper and zinc to microalgae has been described, with particular emphasis on the link between chemical speciation and toxicity Research on the mechanisms of toxicity of metals was extended from the study of simple unicellular organisms to investigating metal toxicity in humans. Novel methods for analysing metals in human sweat, urine and hair were developed, with particular emphasis on lead and manganese These techniques were used to study skin absorption of lead in occupationally-exposed workers and in the study of manganese toxicity in Australian aborigines from Groote Eylandt, Northern Territory Skin absorption was identified as a new route of exposure to inorganic lead in humans The ability of lead salts to enter the body through the skin without significantly raising blood lead levels has important implications for occupational health control because measurement of lead in blood is the main criterion which has previously been used to assess exposure Additional biological monitoring techniques that can detect skin-absorbed lead are now required by occupational health and safety authorities. The research described in this thesis has shown that the mechanisms of toxicity of metals is largely dependant on the chemical form of the metal. By taking into account the speciation of the metal and its mode of action within the cell, it is now possible to predict the toxicity of metals and to identify those factors which ameliorate toxicity in natural waters and biological systems, thus facilitating timely and cost-effective remediation.

▼ This study investigates the coordination behaviour of potentially bi- and tridentate O,O- and O,N,O-donor Schiff base ligands with trivalent lanthanide ions. The reactions of lanthanide nitrates with 2-((E)-(tert-butylimino)methyl)-6-methoxyphenol (HL1) have yielded five complexes that are described by the general formula [Ln(HL1)2(NO3)3] (Ln = Ce, Nd, Gd, Ho and Er) and were characterised using physico-chemical techniques including single-crystal X-ray diffraction spectroscopy. The cerium complex crystallised in a triclinic (P-1) space group, while the rest of the complexes crystallised in the monoclinic (P21/c) space group. All the complexes are ten-coordinate adopting a tetradecahedron geometry with two HL1 molecules coordinated through the phenolic and methoxy oxygen atoms. The coordination sphere is completed by six oxygen atoms from three bidentately coordinated nitrate ligands. Electronic data reveals that only the neodymium, holmium and erbium complexes exhibit weak f-f transitions in the visible region. The redox behaviour of the complexes was also investigated and reported. Five novel complexes were prepared by reacting 2-((E)-(tert-butylimino)methyl)phenol (HL2) with [Ln(NO3)3∙xH2O] (Ln = Gd and Dy ; x = 5 or 6) and [LnCl3∙6H2O] (Ln = Nd, Gd and Dy). The crystal structures of the former two complexes are isostructural and the coordination sphere is composed of three HL2 ligands bonded to the metal centre through the phenolic oxygen atom and three nitrate ions coordinated in a bidentate fashion. Both complexes are nine-coordinate and SHAPE analysis reveals that they adopted a muffin geometry. The average Ln-Onitrate and Ln-Ophenolate bond lengths are 2.5078 and 2.2814 Å, respectively. The complexes derived from the chloride salts exhibited an octahedral geometry with four monodentate ligands [Ln-Ophenolate distances range from 2.224(4) to 2.2797(17) Å] coordinating in the equatorial positions and two chloride ions [average Ln-Cl bond length is 2.6527 Å, and average Cl-Ln-Cl angles is 180o] in axial positions. The ligand coordinated through the phenolic oxygen with the phenolic proton migrating to the imino nitrogen to give a zwitterionic form of the ligand. There are weak C-H∙∙∙Cl interactions present and O-H∙∙∙N hydrogen bonds are also observed in the crystal packing. The synthesis of lanthanide complexes with methoxy-6-((E)-(phenylimino)methyl)phenol (HL3) was carried out in methanol to yield two mononuclear complexes with the formulae [Nd(HL3)2(NO3)3] and [Ho(HL3)(NO3)3(DMF)(H2O)]. Single-crystal crystallographic studies shows that the neodymium complex contains two HL3 ligands coordinated bidentately through its methoxide and phenolic oxygen atoms, with three nitrate ions also bonded to the metal in a bidentate manner. The coordination geometry in the holmium complex is composed of only oxygen atoms from the various ligands. Both complexes are ten-coordinate and exhibit a tetradecahedron geometry.
