Ce travail s'inscrit dans l'activité de production de câbles électriques en cuivre par l'entreprise NEXANS. La coulée continue, située sur le site de Lens, permet d'obtenir des demiproduits se présentant sous forme de fils de cuivre de diamètre 8mm. Si à l’origine ce genre de système de production utilise du cuivre « pur », qualifié d’ETP-1 (pureté >99,99%), aussi appelé cathodes électrolytiques, afin d’obtenir du fil de cuivre, ces derniers années, la coulée continue de Lens a élargi son activité vers le recyclage en introduisant des déchets riches en cuivre sur leur système. On distingue ainsi deux grandes familles de demi-produits ; la première, classée ETP-1, obtenue à partir de cuivre « pur » (Cu-ETP-1), et la deuxième, classée ETP-A, obtenue en introduisant un certain pourcentage de cuivre issu de déchets qualifiés de propres (déchets relativement purs). Cependant, dans cette optique environnementale et économique forte, le retour d'expérience de la chaîne de production a montré ces dernières années des problèmes de fissuration à chaud lors de l'élaboration des demi-produits. Ces problèmes concernent principalement le cuivre ETP-A, donc a priori le cuivre le plus riche en impuretés. Ainsi ces travaux de thèse ont pour but d’expliquer les raisons de ce problème sur la coulée continue en identifiant le(s) facteur(s) responsable(s) et en expliquant leur rôle sur le(s) mécanisme(s) de fissuration. Afin de répondre à cette problématique, après avoir étudié l’influence de l’oxygène et du plomb sur la microstructure par l’intermédiaire des diagrammes de phases binaire Cu-O et ternaire Cu-O-Pb, nous concentrons notre étude sur l’influence de ces impuretés sur les propriétés mécaniques du cuivre. Des essais de traction in situ au Microscope Electronique à Balayage ont été réalisés sur des échantillons à différentes compositions chimiques et à différentes températures afin d’observer leur évolution microstructurale au cours de la déformation tout en reproduisant le phénomène de fissuration observé sur le système de production. Au préalable de chaque essai de traction, des analyses EBSD sont effectuées afin de pouvoir déterminer la localisation de l’amorçage de fissures et d’acquérir de nombreux paramètres pouvant jouer un rôle sur les propriétés mécaniques (texture, facteur de Schmid…). Ces nombreux essais montrent des différences notables de propriétés mécaniques et de mécanismes de fissuration en fonction de nombreux paramètres que nous identifions (température, état de porosité, désorientation associée aux joints de grains, état de précipitation…).

This study takes place in the context of electric wires production using waste copper. Oxygen and sometimes lead are present in small amount in these products. We decide to study their influence on the microstructure and mechanical properties. After studying the influence of oxygen and lead on the microstructure using the binary phase diagram Cu-O and the ternary phase diagram Cu-O-Pb, we focused our work on the influence of these impurities on mechanical properties.…

▼ Mechanistic investigation of copper-oxygen intermediates relevant to the oxygenation reactions of copper monooxygenase enzymes is a long-standing goal of bioinorganic chemists. To elucidate and understand the key species in copper monooxygenase pathways, small molecule synthetic chemistry has been employed to discretely generate and characterize individual species of interest. In Chapter 1, previous enzymatic and modeling work with respect to copper monooxygenase chemistry is discussed and current mechanistic proposals are explored in detail. Chapter 2 describes modeling studies of monocopper sites and the influence of secondary sphere hydrogen bonding interactions on their redox behavior. A series of monocopper complexes with secondary sphere hydrogen bond interactions were determined to result in large increases of the electrochemical potentials of the CuIII/CuII redox couple when compared to non-hydrogen bound analogs. The hydrogen bonding model systems provide evidence for the structure-function relationship of secondary coordination influences on metal-containing active sites. Chapter 3 discusses development of a previously undescribed dinucleating macrocyclic ligand, designed to support dicopper-oxygen cores relevant to the enzyme particulate methane monooxygenase (pMMO). Attempts to generate dicopper-hydroxo type cores resulted in hydrolytic products found to be dicopper complexes that were crystallographically characterized. Observed “paddle wheel” type configurations with cis-labile coordination sites in the dicopper complexes represent a class of compounds with diverse coordination chemistry. The final chapter (Chapter 4) describes the synthesis and characterization of a formal CuIII-alkylperoxo core utilizing spectroscopic and computational methods. The CuIII-alkylperoxo complex has been shown to undergo proton-coupled electron-transfer (PCET) reactions with weak O-H bond substrates. The CuIII-alkylperoxo core is considered to be a model system of a CuIII-OOH core, proposed to be a possible reactive intermediate in lytic polysaccharide monooxygenase (LPMO).

▼ Recent increases in the production of copper by acid-leaching techniques have depleted the supply of iron and de-tinned cans as sources of precipitant for copper from solution. Previous investigators of the iron cementation process have indicated that high purity iron powder, although more costly than detinned cans, has several properties which render it a potential precipitant of copper from leach solutions but few data have been published on the subject. The purpose of this thesis is to investigate the variables encountered in the cementation of copper with iron powder and to obtain data to substantiate indications that the iron consumption could be reduced and a higher grade cement copper could be produced which would compensate, at least in part, for the higher cost of the precipitant. A vertical column mounted on an inverted cone was used as the reaction vessel in the experiments. The pregnant solution was forced into the precipitator through the apex of the cone and the iron powder was added from the top of the column through a small diameter tube. The copper product was removed from the reaction vessel by the effluent solution and collected in a settling tank. Several series of experiments were conducted.to study the influence of variations in the velocity of solution flow through the precipitator, the concentrations of free acid ferrous and ferric ion in the pregnant solution, and the temperature of the pregnant solution on the iron consumption and the grade of the cement copper product. A velocity of solution flow in the column of approximately one centimeter per second was found to be suitable for iron powders retained on a 200 mesh screen. The capacity of the precipitator was reduced considerably with iron powder passing through a 200 mesh screen because iron of that size fraction was easily forced to overflow the precipitator before cementation.is complete. Neither temperature nor ferrous ion concentrations within the normal ranges of operation had any significant effect on the cementation process. Free acid concentrations up to twenty grams per liter were tested with no significant increase in iron consumption. The presence of ferric ion in solution during cementation enhanced the consumption of excess iron appreciably. Excess iron consumption was due to the reaction between metallic copper and ferric ions. The cupric ion produced in the reaction consumed additional iron by the normal cementation reaction. The reaction between metallic iron and ferric ions was not a major contributor to excess iron consumption. The consumption of ferric ion was not excessive at the beginning of experiments, when the surface area of metallic iron was at a maximum, but increased in approximate proportion to the increase in surface area, of metallic copper in the reaction vessel. Although the experiments were conducted with batch additions of iron the results indicated that the cone-column precipitator could be operated continuously by adding precipitant at a rate equal to its consumption. With continuous operation the…

▼ In the cold spray (CS) process, solid powder particles accelerated to several hundred meters a second impact the substrate and deform into splats that are stacked up to form dense coatings on the substrate. However, these deposited splats are not fully bonded to each other, making deposited materials less ductile than wrought materials. In this dissertation, a series of characterization studies of CS deposits of Cu and Cu-alloys are presented, addressing both single-traverse and multi-traverse deposition. Single-traverse deposits were created to investigate the thickness profile and deposition efficiency distributions in single-traverse deposition. Multi-traverse two-spray layer coatings were deposited to investigate the effects of spray parameters, powder characteristics, and post-spray heat treatment on the densification and bonding in the deposited material.; An ultrasonic washing test, developed in this study to determine the locations and extent of poor-bonded splats in coatings deposited multi-traverse CS, revealed that poor-bonded splats were concentrated along the boundaries between successive spray traverses and spray layers. Multi-traverse, two spay-layer Cu coatings sprayed on Al substrates in nitrogen gas at 200 800 °C (473 1073 K) all had virtually full density but their splats were not fully bonded, particularly along spray and spray-layer boundaries. The occurrence of poor-bonded splats decreased with increasing spray gas temperature. Post-spray heat treatment did not improve splat bonding suggesting that oxidation may have had counter effects at the splat boundaries. Use of small powder particles with irregular shape was found to promote splat bonding.; Cu-36Zn-1Mn and Cu-9Al-4Fe coatings sprayed at 400 °C (673 K) and 600 °C (873 K) all had nearly full density but exhibited poorly bonded splats along spray and spray-layer boundaries. Tensile test showed virtually no ductility, also indicating partial splat bonding in these coatings. Pre-annealing of Cu-36Zn-1Mn powder changed the initial β-brass microstructure to a two-phase α+β microstructure, which improved densification through powder softening effects but also degraded bonding due possibly to oxidation. Pre-annealing Cu-9Al-4Fe powder dissolved the intermetalllics in the matrix or transformed them to more stable forms, which improved both densification and bonding.; Models were developed based on a Gaussian mass flow rate distribution in CS to simulate the deposit thickness, the deposition efficiency, the location of poor bonding and the thickness of poor-bonded layers in multi-traverse CS coatings. The poor-bonded layers along spray and spray-layer boundaries and at the interface with the substrate may amount to as much as 24% of the total coating volume, posing an important concern in the fabrication of thick coating by cold spray deposition.

▼ Semiconductors are a broad class of materials and by extension present a large array of possibilities for potential research. This thesis looks at two different areas of semiconductor research. The first is electronic doping of semiconductor nanocrystals and the second is the deposition of copper aluminum oxide via atomic layer deposition (ALD). Semiconductor nanocrystals are semiconductor particles with diameters less than 10 nm. At these size ranges, semiconductor nanocrystals display several unique electrical and optical characteristic due to quantum confinement. Quantum confinement is a phenomenon that arises when the physical size of the nanocrystal is smaller than the wavefunction size of the electrons and holes that allow electrical conductivity in semiconductors. These quantum confinement effects are tunable based on the size of the nanocrystal, which allows one material to have a broad range of possible uses. Even greater control could be had if semiconductor nanocrystals could be doped with heterovalent dopants, as is seen in traditional semiconductors. This thesis look at incorporating group 13 dopants into cadmium selenide nanocrystals and found that while the dopants had effects on the electronic structure of the nanocrystals they were not successfully incorporated into the nanocrystals. The dopants instead were bound to the surface of the nanocrystal. Copper aluminum oxide has generated interest as a potential p-type transparent conductive oxide. Thin films of this material have been deposited via physical vapor methods. Depositing this material via ALD provides a great level of film thickness control, which is critical in many thin film devices. Deposition of copper containing films via ALD has been hampered by a lack of suitable copper precursor. As a solution to that problem, this thesis demonstrates the construction of an ALD deposition system that can use both solid and liquid ALD precursors. This system with its extended capabilities was then used to deposit thin films of copper aluminum oxide using solid copper precursors.

▼ The structures of Cu(II) (DTH)2(BF4)2 (where DTH = 2,5-dithiahexane) and Cu(I) (DTO)2BF4 (where DTO = 3,6-dithiaoctane) have been investigated by single crystal X-ray diffraction techniques. After full matrix least squares refinement of the structures, with anisotropic temperature factors for all non hydrogen atoms in the Cu(II) structure, and for all atoms larger than fluorine in the Cu(I) structure, the conventional R factor converged to a final value of 0.057 for the Cu(II) structure, and 0.082 for the Cu(I) complex. The dark red crystals of the Cu(II) complex belong to the centrosymmetric monoclinic space group P2 1/c. with a = 8.082(3)Å, b = 10.282(3)Å, c = 11.893(4)Å and β = 115.3 degrees. Two dithiahexane ligands and two BF4-ions were found to co-ordinate to the Cu(II) ion to form a tetragonally distorted octahedron, with four Cu(II)-S bonds averaging 2.317Å in length, and two longer Cu(II)-F bonds averaging 2.576Å. The four sulphur atoms are part of two five membered Cu(II)-S-C-C-S rings in which both carbons are on the same side of the plane containing the copper and sulphur atoms. The colourless crystals of the Cu(I) complex were obtained in the non-centric orthorhombic space group Pna2 1, with a = 14.581(2)Å, b = 13.421(2)Å and c = 10.781(2)Å. The molecules exist as discrete monomeric species, with no co-ordination of the BF4- ion to the metal ion. The two ligand molecules co-ordinate to the Cu(I) ion to form a distorted tetrahedron, with the S-Cu(I)-S angles varying between 94.0 and 121.1 degrees. The four Cu(I)-S bonds average 2.307Å in length, and hence are approximately equal to the Cu(II)-S bonds (within experimental error). The two five membered Cu(I)-S-C-C-S rings are both in a gauche conformation, with one carbon below the plane containing the Cu(I) and S atoms, and the other above. The BF4- ion was disordered and was refined using rigid group restrictions. Cu-S co-ordination is thought to occur in some copper containing oxidation-reduction proteins. The observation of similar Cu-S bond distances when Cu(I) and Cu(II) are co-ordinated to thioether ligands (resembling the side chain of the amino acid methionine) may therefore be of direct relevance to the copper co-ordination in such proteins.

▼ In order to test the apparently conflicting predictions of some current theories of strain hardening, slip line length measurements were made on a series of oriented copper single crystals, identically prestrained at 673°K, polished and incrementally strained at temperatures between 573°K and 4.2°K; slip lines formed during low temperature increments were found to be longer than those formed during strain increments at higher temperature (Garner and Alden, 1974). The result is shown to be in conflict with any theory of strain hardening in which slip lines are blocked by specific obstacle configurations, such as Lomer-Cottrell barriers, ribbons of converted pile-ups or dislocation cell walls. In contrast, the result is shown to be consistent with theories of strain hardening in which slip lines are blocked by statistical interaction between expanding glide loops and forest dislocations, on the condition that, within the framework of such a theory, the glide loops are able to expand athermally over a newly available free area of slip plane, after a thermally activated process. Two possible thermally activated processes are discussed. A unified view of slip lines properties is presented which is shown to provide a self-consistent explanation of the temperature variation of slip line length, slip band formation, the existence of multipole carpets and the variation of flow stress with temperature. The statistical aspects of this interpretation were investigated further by obtaining 77°K microstrain curves from a series of oriented copper single crystals, prestrained at temperatures between 1000°K and 77°K, to produce dislocation microstructures with differing degrees of regularity, yet with approximately the same overall density. The forest dislocation microstructures of an identically prepared series of crystals were examined using a dislocation etch on the primary slip plane. A statistical sampling technique was devised, which was used to measure local dislocation densities. In addition, new parameter is introduced, namely the ratio of the sampled standard deviation, to mean local dislocation density, which quantifies the degree of regularity of a dislocation micro-structure. All microstructures were found to have a smaller degree of regularity than a random distribution. For crystals prestrained at temperatures above 293°K, at any given fraction of the 77°K yield stress, the amount of microstrain was found to increase as the microstructures became less regular. Crystals prestrained at and below 293°K exhibited the Haasen-Kelly effect, which was attributed to restricted source operation. However, once sources begin to operate, the amount of microstrain anticipated from the degree of regularity was indeed detected.

▼ This dissertation is divided into two major chapters. The first chapter covers the geology of the Encuentro deposit with emphasis in the intrusion sequence, vein mineral assemblages and distribution, and age of mineralization. The data used for this section includes field mapping, petrography, elemental analysis of biotite, and isotopic geochronology. The second chapter focuses on the pressure-temperature evolution of the magmatic-hydrothermal system at Encuentro and reconstruction of the evolution path for the mineralizing fluids. The basis of this chapter is the application of different geothermometers in both porphyry dikes and different veins present in the deposit. The Encuentro porphyry Cu-Au-Mo deposit is part of the middle Eocene to early Oligocene porphyry copper belt of northern Chile. New core logging observations, together with geologically constrained U-Pb and Re-Os geochronology documents the intrusion sequence and the timing of Cu-Au and Cu-Mo mineralization. A sequence of five porphyry dikes (Eep-1 to Eep-5) of dacitic composition is synchronous with and genetically related to mineralization. The Encuentro porphyry Cu-bearing dikes span from 42.3 ± 0.7 Ma to 41.2 ± 0.6 Ma, based on U-Pb zircon ages via LA-ICP-MS. The earliest intrusion (Eep-1) contains the highest Cu and Au grades; the metal content decreases systematically from oldest to youngest porphyry intrusions. Each porphyry intrusion developed a similar sequence of veins: (1) biotite, (2) early dark micaceous halos (EDM), and (3) a series of A-type quartz-K-feldspar-anhydrite veins (A1 to A5). In each sequence, biotite veins and EDM halos are cut by A-quartz veins. Cu-bearing sulfides are present in all these veins; however, A-type quartz veins contribute most of the Cu-Au and are the most voluminous vein type in the deposit (up to 56 vol.%, averaging 5 vol.% in rocks with >0.3 wt.% Cu). A-type veins are most abundant within and surrounding the upper parts of the porphyry dikes, and displays a concentric distribution in which the volume % of A-type veins is well-correlated with the Cu and Au ore grade. Other veins that are also stable with K-silicate alteration, include the vein sequence (4) B- type quartz-chalcopyrite±molybdenite, (5) quartz-anhydrite-molybdenite ± Cu-sulfides (QAM), and (6) magnetite±chalcopyrite veins. These veins postdate all porphyry intrusions, and offset all earlier biotite veins, EDM halos, and A-quartz veins. QAM veins and to a lesser extent B-type veins contribute the bulk of molybdenum mineralization in the deposit. Four Re-Os ages of molybdenite in different veins types range from 41.3 ± 0.2 Ma to 40.9 ± 0.2 Ma. These dates are consistent with crosscutting vein relationships and also with the 41.2 Ma age of the youngest porphyry (Eep-5) that B-type veins and QAM veins cut. Hence, most of the Mo mineralization likely occurred as a protracted single event immediately following the emplacement of porphyry phase Eep-5. Late veins include the sequence (7) chalcopyrite-pyrite±sericite veins, (8) chlorite-… Advisors/Committee Members: Dilles, John H (advisor), Tepley, Frank (committee member).

▼ Copper (Cu) is crucial for cell function and survival and plays important roles in enzyme-catalyzed metabolic processes, transport of cargo through cellular membranes, and protein breakdown. The mitochondria are home to two important Cu-containing enzymes: cytochrome c oxidase (COX) and superoxide dismutase 1 (Sod1). Delivery of Cu to COX, the terminal electron acceptor in the respiratory chain, is suggested to happen in a bucket brigade fashion via the proteins Cox17, Sco1, and Cox11. Sod1, the other major mitochondrial cuproprotein, is thought to obtain Cu from its chaperone, Ccs1. Because the mitochondria are a central player in Cu storage and regulation, our goal in this study is to analyze how changes in extracellular Cu concentration impact mitochondrial function in Saccharomyces cerevisiae. Our results showed that Cox17, Sco1, and Cox11 responded differently to excess and limiting Cu, suggesting alternate functions for these proteins in mitochondria unrelated to COX assembly. During Cu deficient conditions we noticed an interesting redistribution of mitochondrial Cu: retention of Cu in mitochondrial Sod1 is accompanied by a complete loss of COX activity. This phenotype suggests a regulatory mechanism where Cu is preferentially donated to mitochondrial Sod1 instead of COX when Cu is limited. Interestingly, we also find that Cu redistribution in the mitochondria is affected when we change the primary carbon source from glucose to galactose. We propose that Cu distribution in mitochondria is controlled by an affinity gradient. Analysis of cell cycle progression showed that in excess Cu, yeast displayed a cell cycle defect while Cu deficient conditions did not affect cell cycle progression. Strikingly, changing the primary carbon source to galactose led to a cell cycle defect in the presence of a Cu specific chelator. Overall, we suggest that the presence of mitochondrial Sod1 is essential for cell cycle progression. The protein machinery responsible for Cu homeostasis has been well characterized, however the transport of Cu to cellular compartments and regulatory mechanisms involved in Cu import and export are not fully understood. We now demonstrate a novel phenotype that provides insight into regulation of Cu within the mitochondria. Additionally, we find that mitochondrial Cu distribution is affected by carbon source, and is associated with changes in cell cycle progression. These findings further our understanding of Cu homeostasis in yeast, and will likely have implications on Cu-related disorders, such as Menkes disease.

▼ Marked differences in the sensitivity among fish life-stages and species have been observed for cadmium (Cd) and copper (Cu), two contaminants of particular concern in Canadian surface waters. White sturgeon (Acipenser transmontanus) are highly sensitive to metals such as Cu. Moreover, white sturgeon have also shown significant life-stage-specific differences in sensitivity to metals. When compared to rainbow trout (Oncorhynchus mykiss), white sturgeon are more sensitive to waterborne acute Cu exposure, whereas the trend in sensitivity is reversed with Cd exposure. The mechanisms of life-stage- and species-specific differences in sensitivity among fish species are not well understood, especially for data-poor, non-model species such as white sturgeon. Hence, the overall objective of this study was to characterize the physiological, biochemical and molecular drivers of species-specific differences in the sensitivity of white sturgeon and rainbow trout to Cd and Cu over three different early life-stages. During acute waterborne exposure to Cd and Cu, the most important mechanisms of toxicity are the disruption of calcium (Ca) and sodium (Na) homeostasis, respectively. Therefore, I compared the effect of Cd and Cu on uptake and whole-body levels of Ca and Na, respectively, between rainbow trout and white sturgeon across multiple early life-stages. I showed that the greater sensitivity of white sturgeon to Cu was explained by greater reduction of its sodium Na uptake compared to rainbow trout, when exposed to same waterborne Cu concentration. Similarly, higher sensitivity of rainbow trout to Cd was explained by significantly higher reduction in Ca uptake relative to white sturgeon. With both Cu and Cd, reduction in whole-body ion uptake resulted in reduction of whole-body levels of Na and Ca, respectively, and the response level was significantly higher in the more sensitive species. Additionally, I analysed Cd/Cu accumulation, Cd/Cu induced oxidative stress, metallothionein and heat shock protein responses and compared these parameters between rainbow trout and white sturgeon across multiple early life-stages. Species-specific differences in these parameters were evaluated because they are known to be important pathways through which Cd and Cu cause toxicity. In larval and swim-up life-stages, white sturgeon showed greater Cu-induced oxidative damage (lipid hydroperoxide (LPO) induction) than in rainbow trout, which explained the greater sensitivity of white sturgeon to Cu in early life-stages. Similarly, exposure to Cd showed that rainbow trout, the more sensitive species to Cd, had significantly greater LPO induction at the swim-up and juvenile life-stages as compared to LPO levels in the respective life-stages of white sturgeon. Mechanisms such as antioxidant enzymes, antioxidant molecules, metal accumulation and metallothionein could only partially explain the patterns observed in Cd or Cu induced LPO levels with no consistent response across life-stages. Regardless of the underlying mechanism, LPO seems to be a… Advisors/Committee Members: Janz, David, Krone, Pat, Jardine, Tim, Ferrari, Maud.

▼ This study presents a significant advancement in the understanding of the uptake of Cu2+ by nanostructured calcium silicate (NCaSil) and to develop a strategy of using it in a continuous manner using packed columns. The NCaSil structure consists of micro-sized agglomeration of nanometre-sized platelets of calcium silicate. This arrangement grants the material a large surface area of 400 to 600 m2 g-1. The kinetics and thermodynamics of the adsorption of Cu2+ onto NCaSil in batch were studied at temperatures ranging from 277 to 333 K. The reaction between Cu2+ and NCaSil occurred rapidly, being endothermic and exhibiting an increase in the entropy meaning that the adsorption process became more spontaneous when the temperature was increased. Furthermore, the uptake resulted in the formation of copper sulfate hydroxide minerals in the form of Cu4(OH)6SO4·nH2O, where n is equal to 2 for wroewolfeite, 1 for posnjakite and 0 for brochantite. Using powder X-ray diffraction and scanning electron microscopy it was proven that at temperatures between 293 and 313 K wroewolfeite and posnjakite were intermediates in the formation of brochantite. Specifically at high temperatures of 333 K and Cu2+ concentrations higher than 15.7 mmol L-1 the reaction proceeded directly to the formation of the thermodynamically stable compound brochantite. A kinetic study of the crystal growth was carried out using powder-XRD which showed that the rate determining step towards the formation of brochantite is the nucleation of SO4 2-. Additionally, a value for the activation energy of 42 kJ mol-1 using powder-XRD data was obtained for the formation of the crystallographic plane 420 in the brochantite crystal. A sample of a real mining waste was collected and analysed. Based on this sample an emulated waste was generated. The NCaSil was tested for the uptake of Cu2+ ions from this emulated mining waste, showing that the use of NCaSil is feasible at pH values greater than 3. The production and use of NCaSil may be coupled to existing mining waste treatment processes in order to remove dissolved copper from solution and produce a copper rich solid as the by-product. NCaSil was packed inside a conventional axial flow column and a radial flow column, which was developed as part of this project. The former proved to be impractical due to a large pressure drop through the column, while the latter was impractical due to short operational times before breakthrough. Nonetheless, the radial flow column was operated by immersion in a tank exhibiting similar kinetics of copper ions uptake to those observed in batch processes. Therefore, the scale-up of this process was proposed including the necessary equations keeping the ratio of the tested radial flow column. Advisors/Committee Members: Johnston, James.

▼ Studies done on Mimbula ore have been on agitation leaching, high temperature and pressure leaching and treatment of refractory ore (TORCO) process. However these methods attracted significantly high capital investment leaving heap leaching as a more economically attractive method to be investigated. This research was aimed at assessing the amenability of Mimbula refractory ore to heap leaching and to understand the conditions under which copper dissolution can be enhanced. The specific objectives were to determine the optimum conditions for agglomeration, the optimum bed height that gave the best leaching efficiency and to establish the relationship between bed height and leaching efficiency. Ore characterisation was done to establish the chemical and mineralogical compostion of the ore. Agglomeration and column leaching experiments were carried out in agglomeration drum and PVC pipes respectively. In order to validate the experiments, each experiment was repeated three times. The soak test, agglomerate size distribution and visual inspection were used as the tools for evaluating the agglomerates quality. For all the column leaching experiments, a chemical and mineralogical composition analyses of feed (ore) and leach residues was carried out in order to measure the extent of copper dissolution. The optimized agglomeration parameters were 600 gpt binder dosage, 14 % moisture content of ore, 20 rpm agglomeration speed and 3 min residence time. Agglomeration greatly improved the leach efficiency and kinetics. The highest leach efficiency of 60 % was obtained with agglomerated ore in 12 days compared to 32 % for unagglomerated ore in 94 days. The mineralogical analysis showed that about 90 % of the cupriferous mica dissolved into solution whilst chrysocolla and pseudomalachite completely dissolved in solution. However, sulphides, especially chalcopyrite were difficult to leach under the conditions employed. It was concluded that Mimbula refractory copper ore is amenable to heap leaching. Further studies to improve dissolution of sulphide minerals using acidified ferric sulphate and/or bioleaching were recommended.

▼ Copper is one of a minimum of thirteen known essential metals in eukaryotic biology, there are some prokaryotic and archae for which copper is likely not essential. This essentiality derives from the one-electron redox couple provided by the change between its di- and mono-valent forms and is utilised by a number of key redox enzymes. However, the same redox couple is responsible for the toxicity of copper, if its transport is uncontrolled within the cell. Imbalance between intake, storage, and excretion of copper can harm the cell and ultimately lead to the death of the organism. General mechanisms of copper homeostasis are understood but many details remain unclear. This work examines the chemistry and interaction of key proteins of copper’s pathway through mammalian cells to the trans-Golgi network. Glutaredoxins (Grxs) have been characterised as enzymes regulating the redox status of protein thiols via the cofactors glutathione (GSH) and glutathione disulphide (GS-SG). However, such a function has been demonstrated in model systems only using low molar mass compounds as substrates. It has not been demonstated with physiologically relevant protein substrates. The active sites of Grxs frequently feature Cys-xx-Cys motifs. Such motifs are also present as high affinity copper binding sites in copper-transporting proteins such as Atox1, a human cytosolic copper metallo-chaperone and in the metal binding domains of the copper transporting ATPases ATP7A and ATP7B. However, it has been predicted that this motif in hGrx1 does not bind copper. The aim of this study was to determine crucial thermodynamic properties of the proteins involved and to highlight their differences and similarities. These properties are essential to an understanding of functions of these proteins. In this work, it is demonstrated that: - (i) The active site Cys23-Pro-Tyr-Cys26 in human glutaredoxin 1 (hGrx1) can bind Cu(I) tightly with femtomolar affinity (KD = 10-15.5 M) and possesses a reduction potential of E°’ = -118 mV at pH 7.0. In contrast, the Cys12-Gly-Gly-Cys15 motif in Atox1 has a higher affinity for Cu(I) (KD = 10-17.4 M) and a more negative potential (E°’ = -188 mV). (ii) hGrx1 efficiently catalyses interchange of the dithiol and disulfide forms of the Cys12-Gly-Gly-Cys15 fragment in Atox1 but does not act upon the isolated single residue Cys41; (iii) The direction of this catalysis is regulated by the reduction potential imposed by the redox couple GS-SG/2GSH ratio and the availability of Cu(I). The final chapter describes the optimization of cell-free expression of the human copper transporter (hCtr1) and some initial characterization of its oligomeric state in detergent-solubilised form. Additionally, initial results for the incorporation of hCtr1 into lipid bilayer systems are presented. This step will be crucial for future copper binding and translocation assays.

Depuis des décennies, la chimie du fluor est un domaine suscitant un fort intérêt. Bien que de nombreuses méthodologies originales et élégantes aient été développées pour introduire des groupements fluorés variés, le résidu CF2PO(OEt)2 reste encore peu étudié. Cela contraste avec ses propriétés uniques et à hautes valeurs ajoutées. En effet, le motif CF2PO(OEt)2 s'est avéré être un bioisostère métaboliquement stable du groupement phosphate, ce dernier étant particulièrement instable in vivo en comparaison. En conséquence, des approches pour incorporer ce motif au sein de molécules ont été développées bien qu'encore limitées à un nombre restreint de transformations. Dans le cadre de cette thèse, nous souhaitons proposer une méthode générale et directe pour accéder à des molécules contenant le groupement CF2PO(OEt)2. La première partie de cette thèse a été dédiée à l'introduction du motif CF2PO(OEt)2 sur des sels d'iodonium comportant un substituant aryle, heteroaryle, ou dérivés d'alcènes et d'alcynes, mettant en jeu la génération d'une espèce de type CuCF2PO(OEt)2 (Chapitre II). Puis, l'utilité et la généralité de cette transformation a été démontrée lors de la fonctionnalisation de dérivés de type R-X (R = vinyle, allyle et benzyle) ainsi que des disulfures en tant qu'électrophiles. Par ailleurs, une réaction de couplage de type Ullmann réalisée à température ambiante a été étudiée. Finalement, la réactivité divergente de l'espèce CuCF2PO(OEt)2 envers les α-diazoesters, par un simple changement du sel de cuivre, a été examinée (Chapitre III). Cette approche a été étendue par la suite aux dérivés d'α-bromocétones afin d'offrir une voie d'accès aux cétones contenant un motif SCF2PO(OEt)2 en position α (Chapitre IV).

Since several decades, the organofluorine chemistry is a research area of strong interest. While plenty of original and elegant methodologies were developed to introduce various fluorinated groups, the CF2PO(OEt)2 residue was scarcely spotlighted. This contrasts with its unique and highly valuable properties. Indeed, the CF2PO(OEt)2 moiety proved to be a metabolically stable bioisoster of the in vivo unstable phosphate group. As a result, approaches to incorporate this motif onto molecules were developed albeit still restricted to few transformations. In this PhD thesis, we would like to propose a general and straightforward method to access CF2PO(OEt)2-containing molecules. A first part was dedicated to the introduction of the CF2PO(OEt)2 motif on aryl, heteroaryl, vinyl and alkynyl iodonium salts, by generating the CuCF2PO(OEt)2 species (Chapter II). Then, the utility and the generality of this transformation were further demonstrated using R-X (R = vinyl, allyl and benzyl) as well as disulfides as the electrophiles. Besides, a Ullmann-type cross-coupling reaction proceeding at room temperature was also studied. Finally, the divergent reactivity of the CuCF2PO(OEt)2 species toward α-diazoesters, by a simple change of copper salt, was investigated (Chapter III). This approach was then extended to…

▼ The redox chemistry of copper in natural aquatic systems is of great interest due to its significance to the biogeochemistry of copper, an essential micronutrient, and also due to the formation of reactive oxygen species (ROS) during these redox reactions. Despite this, many knowledge gaps pertaining to the redox transformations of copper exist, particularly in systems containing oxygen where copper species may be simultaneously oxidized and reduced. In order to improve our understanding of copper redox chemistry under conditions typical of oxic natural waters, the oxidation kinetics of nanomolar concentrations of Cu(I) in NaCl solutions was firstly investigated over the pH range 6.5 – 8.0. The overall apparent oxidation rate constant was strongly affected by chloride, moderately by bicarbonate and, to a lesser extent, by pH. Two kinetic models have been developed, using both the speciation-based approach and the so-called “CuL” approach with both models validating the conclusions that i) the oxidation of Cu(I) by oxygen and superoxide are important pathways at all pH values and chloride concentrations considered and ii) the simultaneous oxygenation of Cu+, CuClOH– and CuCO3– is the rate-limiting step in the overall oxidation of Cu(I) with the back reduction of Cu(II) by superoxide only becoming important at low chloride concentrations.As electron-transfer mediators, quinone moieties play important roles in essential biogeochemical processes and serve as a vital link in the movement of electrons through cells and tissues. Copper has previously been shown to catalyze the oxidation of hydroquinones and enhance the hydroquinone-induced cytotoxicity. As such, in the second phase of the project, the oxidation of 1,4-hydroquinone (H2Q) and 1,4-naphthohydroquinone (NH2Q) in the absence and presence of nanomolar concentrations of Cu(II) in NaCl solutions at circumneutral pH has been investigated. While the autoxidation of H2Q is slow under the conditions studied, the autoxidation of NH2Q is significant with the apparent oxidation rate increasing with increasing pH and the initial NH2Q concentration. The results also show that under aerobic conditions, copper is capable of catalyzing the oxidation of H2Q and NH2Q, with concomitant oxygen consumption and peroxide generation. The presence of O2 facilitated the catalytic role of Cu(II) with regeneration of Cu(II) via continuous oxidation of Cu(I) and rapid removal of semiquinone radicals resulting in the generation of superoxide. Detailed kinetic models have been developed to describe the predominant mechanisms operative in these systems. The half-cell reduction potentials of different redox couples indicated good agreement between thermodynamic and kinetic considerations of various key reactions involved, further providing confirmation of the veracity of the proposed models describing the interactions of copper and quinone species in circumneutral pH saline solutions.

▼ Employing copper (Cu) plating as an alternative to screen-printed silver (Ag) for silicon (Si) solar cells can offer significant cost benefits. However, concerns that Cu may penetrate through nickel (Ni) barrier layers into Si where it impacts cell performance and module durability have contributed to the limited adoption of plated metallisation in manufacturing. This thesis aimed to investigate the thermal stability of Cu-plated Si solar cells with a particular focus on cells with Ni/Cu grids plated on openings formed by selective-ablation of the antireflection coating using a UV ps laser.The formation of Cu precipitates in float-zone-Si was investigated using advanced lifetime spectroscopy of temperature and injection-dependent lifetime curves, with two defect levels identified at Et-Ei = −(0.14-0.16) eV and Et-Ei = (0.08-0.11) eV. Different capture cross-section ratios were obtained for Cu precipitates formed under illumination (k = 1.4 ± 0.2) and ingot-grown precipitates (k = 5.6 ± 1.4). A power-law dependence of the capture cross section was identified (with α=1.35-2.54) and α was observed to increase with increasing precipitate size/density, the latter being theorised to be related to the faster precipitation rate under illumination generating smaller precipitates.A physics of failure methodology was used to characterise Cu diffusion from plated contacts and degradation in Cu-plated p-type PERC and n-type PERT solar cells during thermal testing. Significant Cu diffusion through Ag capping layers was observed during treatments at 200 °C, the extent of the diffusion depending on the capping layer microstructure. Voids which formed as a result of Cu diffusion distorted Suns-VOC measurements, leading to 5-10% errors in the measured pseudo fill factor of the cells. Cross-sectional imaging (FIB/TEM/EDS) and LA-ICP-MS were used to identify that Ni and Cu can penetrate into Si on heating, with increased Ni/Cu detection correlated with increased electrical degradation. Finally, thermal treatments both in the dark and under illumination revealed increased degradation of p-type PERC cells under illumination due to Cu-LID, whilst non-uniformities in the laser-ablation and Ni barrier formation were proposed as the most probable reasons for the observed variable thermal stability of Cu-plated contacts to the p-type PERC and n-type PERT cells.
