▼ The microbial community structure and function in acidic, high-temperature ironoxidizing geothermal springs of Yellowstone National Park was investigated utilizing a variety of complementary approaches including microbial cultivation and characterization, geochemical analysis of aqueous and solid phases, phylogenetic and functional gene analysis, comparative genomics, and protein sequence modeling. Cultivation efforts resulted in the isolation of an Fe(II)-oxidizing chemolithotroph Metallosphaera yellowstonii MK1 T. The distribution and relative abundance of MK1-like 16S rRNA gene sequences was evaluated in 14 acidic geothermal springs containing Fe(III)-oxide microbial mats. Highly related MK1-like sequences (>99% sequence similarity) were consistently observed in Fe(III)-oxide mats across a temperature range of 55 to 80 °C. Quantitative PCR confirmed that organisms highly similar to strain MK1 comprised up to 40% of the total archaeal community of selected sites. Four additional isolates were obtained from thermophilic Fe(III) microbial mats including Sulfobacillus sp. MK2, Sulfolobus sp. MK3, Acidicaldus sp. MK5 and Crenarchaeota sp. MK4, which represents a new taxonomical lineage at the class level or higher. A draft genome has been assembled for M. yellowstonii strain MK1 and comparative studies indicate significant similarity to Metallosphaera sedula in regards to putative genes involved in iron and sulfur oxidation, carbon fixation, oxygen reduction and heavy metal resistance. Analysis of gene sequences reveal 7 heme copper oxidases (subunit I) and a variety of genes with possible importance in Fe(II) oxidation including the foxA-J gene cluster, a cbsA cytochrome b 558/566, and a novel sequence coding for a putative blue multi-copper protein (mco). Expression screens and reverse transcriptaseqPCR on samples from three ASC environments and in cultures grown autotrophically show that the fox gene cluster and mco are important when Fe(II) serves as the electron donor. Protein sequence analysis of foxC indicates a novel lysine-lysine or lysine arginine heme b binding domain and is likely the cytochrome component of a heterodimer complex with foxG as a ferredoxin subunit. Analysis of mco indicates a novel multicopper blue protein with two plastocyanin type I copper domains with only three homologous sequences found in Genbank. Both putative proteins likely play an important role in electron transport from Fe(II) to oxygen through Fox Proteins. Advisors/Committee Members: Chairperson, Graduate Committee: Williams P.

▼ Asphalt paved road is one of the building blocks of the modem world. Flexibility is one of its major advantages; however, this flexibility suffers from asphalt oxidation since the first day of pavement service life. Several elements of binder oxidation have been investigated, such as oxidation kinetics, asphalt hardening in response to oxidation, pavement design, and environmental conditions. Based on understandings on those elements, pavement oxidation models have been developed to predict the oxidation rates in pavements in specific locations. This prediction contributes greatly to reducing the pavement life cost and elongating pavement service life. However, experimental methods to determine required model inputs, values of those oxidation elements, seriously limit the model application. This work focuses on understanding the elements of asphalt oxidation and on exploring applications of the pavement oxidation model. This dissertation presents a detailed investigation of pavement oxidation, two new test methods to obtain the model inputs, and a study on dynamic diffusion-reaction balance. First, a detailed investigation on pavement oxidation was reported to give some general conclusions about asphalt oxidation rates vary largely in different climate zones, and pavement design defines thickness of the asphalt film and thus controls aging. Secondly, new methods to obtain the model inputs were proposed: (1) Aging tests on laboratory made asphalt concretes have been proven as new information sources on asphalt concretes aging to replace sampling field cores. This method makes a pavement oxidation prediction before construction a reality; (2) Aging on recovered asphalt binders have been proven as new information sources on asphalt kinetics and hardening properties. This method solves the problem that original binders are not available in many cases. With the data obtained from these aging tests, long term oxidation predictions for the pavements were made using the pavement oxidation model and validated their accuracies by field data, including one complicated case, a layer-by-layer prediction on a seal coat treated pavement. To better understand the asphalt aging process, the last topic in this dissertation was to study a dynamic balance between oxygen diffusion and oxidation reaction using the pavement oxidation model.

▼ The presence of the hormones estradiol and testosterone in the environment is of concern because they adversely affect vertebrate sexual characteristics. Landspreading broiler litter introduces these hormones into the environment. To determine the fate of these hormones in the soil, two studies were conducted. The first study determined the mineralization of 14C-labeled estradiol and testosterone at three water potentials (-0.03, -0.75 (17 β-estradiol only), -0.075 (testosterone only), and -1.5 MPa) and temperatures (10, 20, and 30°C). Radiolabeled CO2 (from mineralization) was captured in 1 M KOH traps and measured by liquid scintillation. With a few exceptions, the mineralization of estradiol either stayed the same or increased (1.5 to 13.8%) with increasing temperature and increasing soil water content. With a few exceptions, the mineralization of testosterone either stayed the same or increased (19.5 to 48.0%) with decreasing temperature and increasing soil water content. For both hormones, mineralization was dependent on soil type. The second study determined the incorporation of 14C-labeled estradiol and testosterone into a) three soil organic matter (SOM) fractions (fulvic acid, humic acid, and humin) at two water potentials (-0.03 and -1.5 MPa), two temperatures (10 and 30°C), and one sampling time (168 days), and b) at one water potential (-0.03 MPa), one temperature (30°C), and seven sampling times (0, 1, 3, 7, 14, 28, and 56 days). Both incorporation studies were conducted in a Cecil sandy loam. After the hormones (mixed with broiler litter) were mineralized on the soil surface, SOM fractions were extracted and analyzed separately with liquid scintillation and biological oxidation. As time increased, higher temperature and water potential decreased percentages of 14C estradiol and testosterone in water- and acetone-soluble fractions and increased percentages in SOM fractions. However, the distribution of the two hormones in SOM fractions differed. For estradiol, higher temperature and water potential increased the percentage in all three SOM fractions. For testosterone, higher temperature and water potential increased the percentage of hormone in fulvic acid and humin. Because more and more estradiol and testosterone become incorporated into SOM over time, landspreading these hormones may be less of an environmental concern than previously considered.

▼ Lipid autoxidation is one of the central economic concerns to the edible oil and food & beverage industry. The chemistry of this degradation reaction has been understood for many decades, but successful means to predict or optimize oxidative stability have proved elusive. It is speculated here that an ongoing hindrance to these efforts has been the lack of consistency of assay selection, study design, and numerical interpretation technique among scientists attempting to quantify oxidative stability within fats and oils. This study monitored 50 samples of current commercial-use edible fats and oils for the accumulation of lipid autoxidation products according to four distinct assays throughout two months of accelerated storage. This oxidation data was examined for the derivation of a single novel comprehensive quantification of a sample’s exhibition of oxidative stability. This comprehensive term was then used as the basis for the development of predictive models of oxidative stability according to numerous composition factors. Sample unsaturation (as concentrations of monounsaturated fatty acids, diunsaturated fatty acids, and triunsaturated fatty acids) demonstrated a strong correlation (R2 = 91.5%) with the stability term, and indicated the combined presence of multiple double bonds on individual fatty acids to be associated with impaired oxidative stability. A systematic sequential approach to model-building was then employed to negotiate the challenges of inherent redundancies within the composition variables of edible fats and oils. Independent of sample unsaturation, triacylglycerols containing one, two, and seven double bonds were positively associated with stability, and the concentrations of triacylglycerols containing three, four, five, and six double bonds were negatively associated with stability. trans-Fatty acids, sample purity, and α-tocotrienol were also associated with improved stability. Unsaturated fatty acids greater than 18 carbons in length and γ-tocotrienol were both associated with impaired stability. Final models including considerations of these factors were highly predictive of oxidative stability (R2adj = 97.1% for oil blends and R2adj = 96.2% for pure samples).

▼ Two novel arsenite oxidation processes in Mono Lake, CA, and the organisms involved in these processes were identified. Arsenate was produced when anoxic live Mono Lake water samples were amended with arsenite and selenate, but it was not produced in filtered or killed control samples. A pure culture capable of selenate-dependent anaerobic arsenite oxidation was isolated from Mono Lake. Washed cells experiments with this culture demonstrated that the oxidation of arsenite is tightly coupled to the reduction of selenate. Strain ML-SRAO is not autotrophic and grows optimally on lactate with selenate as the electron acceptor. TStrain ML-SRAO is a Gram-positive, non-motile, spore-forming rod that can respire oxygen, nitrate, and arsenate in addition to selenate. The arsenate reductase gene (arrA) from strain ML-SRAO was highly similar to arrA genes from other Mono Lake arsenate reducers. TComparison of 16S rDNA sequences of closely related organisms showed that ML-SRAO and six other classically defined Bacillus species formed a distinct phyletic group The nearest Trelative, Bacillus agaradhaerens DSM 8721, was 96.1% similar based on comparison of nearly full length (>1500 bp) 16S rRNA gene sequences. We proposed that Bacillus agaradhaerans TDSM 8721 and five other closely related species be reclassified to the genus Natrobacillus gen. Tnov. The distinct phylogenetic identity and metabolic capabilities of ML-SRAO suggest that it is a novel species, for which the name Natrobacillus oremlandii sp. nov. is proposed. Tthe effects of sulfide on aerobic arsenite oxidation in alkaline lake water samples and in laboratory enrichment cultures were also examined. Significant arsenite oxidation occurred only in treatments with bacteria present, and production of arsenate was greatly enhanced by the addition of sulfide or thiosulfate. IC-ICP-MS analysis of samples showed that mono- and di-thioarsenate formed in arsenite + sulfide amended lake water. Enrichment culture experiments suggest that sulfur-oxidizing bacteria use free or arsenic-bound sulfur as a growth substrate and directly or indirectly transform arsenite and thioarsenates to arsenate during growth. Sulfur-driven arsenite oxidation and microbial thioarsenate transformation may be important biogeochemical processes in the arsenic cycle of our study site (Mono Lake, CA, USA) and other alkaline environments as well.

▼ The first part of this thesis describes a study of the characteristics of oxidation of a 1:2 iron(III):thiolate system in methanolic solution and in water. This system was investigated as a potential analog for the cysteine- and cysteamine-dioxygenase catalyzed 0₂-oxidation of cysteine and cysteamine, respectively, to the corresponding sulfinic acids. In the neutral pH range, oxidation by 0₂ and H₂0₂ of a stoichiometric mixture of 1:2 iron(III):cysteine in aqueous solution produced cysteinesulfinic acid, (CyS0₂H) and cysteic acid, (CyS0₃H) , reported as CyS0x⁻ (with yields of 4.1-24.6%), in addition to the principal product, cystine (CySSCy). All amino acid material was separated by ion exchange chromatography and detected quantitatively by standard ninhydrin colorimetric analysis or gravimetric analysis. The primary mechanism pertaining to oxidation of CyS⁻ to CyS0x⁻ involves the proposal of an initial four atom "cluster", [-(FeII)₂(SCy)₂-1]n, which on oxidation with 0₂ generates H₂0₂ and [-(FeIII)₂(SCy)₂-1]n⁺². The active oxidant would then in turn react with an available Fe(III)-thiolate bond forming the S-bonded sulfenate ligand. An IR spectrum of the oxidized solid from the product mixture supports this proposal. An alternative mechanism would be the direct 0₂-oxidation of an Fe(III) coordinated thiolate to (Fe-S(0)₂Cy]. This oxidative mode seems to be active at low Fe(III) concentration in the presence of excess thiolate in slightly alkaline medium. Early iron-thiolate studies were carried out using the thiol, penicillamine. Syntheses of penicillaminesulfinic acid were explored. The syntheses of K₃[(S- PenS-N,S)₃] and of yellow K₃[(S-PenS0₂-N,S)₃] were performed. The ¹H nmr and UV-visible spectra are reported. The decomposition of K₃[(S-PenS0₂-N,S)₃] with ethylenediamine provided the best yield of the sodium salt of the penicillaminesulfinate ion. The molecular acid was unstable in acidic or near neutral, aqueous solution, and therefore was not isolated. The second part of this thesis details the synthesis of bis-penicillaminato-N,S,0-cobaltate(III) complex and its stoichiometric H₂0₂-oxidation resulting in isolation of Na[Co(S-PenS-N,S,0)- (S-PenSO-N,S,0)] and Na[Co(S-PenSO-N,S,O)₂]. The UV-visible, IR and ¹H nmr spectra of these cobalt(III) complexes are reported. Techniques were developed and refined during the study which made possible the separation and identification of the oxidation products, using anion exchange chromatography and gel filtration. Determination of the chirality of each sulfenato sulfur atom was made using applications of circular dichroism. Structures for the several complexes are postulated, based on the combined spectral results. The second-order rate constants for oxidation of the thiolato and the sulfenato complexes were measured under pseudo-first-order conditions. By analogy with the results of the oxidation of Fe(III) and Co(III) complexes studied, proposals on the mechanism and stoichiometry of the reaction at the active site of the cysteine… Advisors/Committee Members: Krueger, James H.

▼ This research was on the irreversible oxidation of trimethylamine by copper(II) chloride, which takes place at temperatures of about 75° and higher. The coordination of trimethylamine by copper(II) chloride, which is a preliminary reaction to the oxidation, was studied at 0°. The coordination of trimethylamine by the potential reduction product, copper(I) chloride, was also studied at 0°. High vacuum and dry nitrogen glovebox techniques were used in studying the coordination reactions, the stoichiometry of the oxidationreduction reaction, and the hydrolysis of the redox reaction products. Complexes in the copper(II) chloride - trimethylamine system at 0° are a blue-green solid, presumably CuCl ₂ N(CH₃)₃, with a dissociation pressure of several hundred torr, and the yellow-brown solid CuCl₂N(CH ₃)₃' which has a negligible dissociation pressure. The latter, which had been reported previously, exhibits normal paramagnetism at room temperature. Copper(I) chloride and trimethylamine at 0° form the stable complex CuCl N(CH₃)₃. The following reaction can be written for the irreversible thermally induced oxidation-reduction reaction. 2 CuC1₂+ 2 N(CH₃)₃ – -> 2 Cu Cl + (CH₃)₃NH⁺C1⁻ + (CH ₃) ₂ =CH⁺₂ Cl⁻ When the reactants were present in equimolar amounts the reaction stoichiometry was approximately 1:1. The dimethylmethyleneammonium and trimethylammonium caticais were identified by their characteristic infrared frequencies. The presence of the former was also indicated by the identification of its hydrolysis products, formaldehyde and dimethylamine. When trimethylamine was present in excess, the amine: copper(II) chloride reaction stoichiometry was variable, in the range 1.1 to 1.4:1. This is attributed to various complex equilibria involving copper(I) chloride, and to the reaction of trimethylamine with the dimethylmethyleneammonium cation to give a polymeric product. The results on the trimethylamine coordination complexes of copper(I) and copper(II) chloride differ from some previous reports in the literature. The oxidation of trimethylamine by copper(II) chloride closely resembles its previously described oxidation by vanadium(IV) chloride. Advisors/Committee Members: Yoke, John T. (advisor).

▼ This project was concerned with the evaluation of three potential synthetic routes for 3-tert-butyl-4-methoxybenzaldehyde, a useful fine chemical intermediate and ingredient in many sunscreen agents. The three synthetic routes all involved the selective oxidation of the 3-tert-butyl-4-methoxytoluene to the desired benzaldehyde by (a) catalytic air oxidation, (b) direct electrochemical oxidation, and (c) indirect electrochemical oxidation. In order to decide whether catalytic oxidation should precede the alkylation of 4-methoxytoluene, the selective oxidation using the well-known cobalt(II)- bromide catalyst system in acetic acid solutions were investigated with the view to determine whether increased electron density on the aromatic ring improves selectivity to the desired benzaldehyde or not. In addition, the effect of various important reaction variables was also investigated. These studies showed that increased electron density, hence increased substitution, increases the desired benzaldehyde selectivity. In addition, while reaction conditions such as reaction temperature, catalyst concentration, water concentration, etc. may be optimised for maximum 3-tert-butyl-4- methoxybenzaldehyde yields (~80 percent), such yields can only be achieved at relatively low (<40 percent) alkoxytoluene conversions. The direct electrochemical oxidation of 3-tert-butyl-4-methoxytoluene was investigated in methanol solutions containing various supporting electrolytes and using constant current electrolysis with the intention of optimizing the production of 3-tert-butyl-4-methoxybenzyl dimethyl acetal which can later be hydrolyzed using sulfuric acid to the 3-tert-butyl-4-methoxybenzaldehyde. In this study, various parameters such as supporting electrolyte and electrodes were studied. Previous studies showed undoubtedly that methanol as a solvent gave better results amongst the rest of the solvents. Indirect route was also studied as a method of synthesizing 3-tert-butyl-4- methoxybenzaldehyde and compared to the direct electro synthesis.

▼ The selective, liquid phase oxidation of p-cymene is an important synthetic route for the production of p-cresol via the tertiary cymene hydroperoxide (TCHP). The industrial-scale oxidation process is characterised by slow oxidation rates due to limitations in the mass transfer of oxidant (gaseous oxygen) into the liquid phase. However, like all other autoxidation reactions, the oxidation reaction is exothermic, following the typical free radical autoxidation reaction mechanism, which implies that careful temperature control is critical in order to prevent the further reaction of the initially formed hydroperoxide species. In the presence of metal catalysts, the limiting oxidation rate is the transfer of oxygen from the gas to liquid boundary interface. As a result, low product yields and poor productivity space-time yield are typically experienced. At high substrate conversions, by-products resulting from the decomposition of the formed hydroperoxides predominate. For this reason, the conversion of substrate is restricted to preserve the TCHP selectivity. The slow rates in industrial-scale p-cymene oxidations results in long oxidation times, typically 8-12 h. Substrate conversions are typically between 15-20 percent, and the TCHP selectivity ranges between 65-70 percent. The work described in this thesis concerns the oxidation of p-cymene in a microstructured falling film reactor (FFMSR). These reactor systems facilitate chemical reactors to have high mass and heat transfer rates because of high surface area-to-volume ratios. Due to their small internal volumes, these reactors are inherently safe to operate. These properties were exploited to improve the p-cymene oxidation rate and, consequently, the space-time yield. In order to evaluate the suitability of vanadium phosphate oxide (VPO) catalysts for use as supported catalyst in the FFMSR, different catalysts prepared from VOHPO4∙0.5H2O and VO(H2PO4)2 precursors was first evaluated for the oxidation of p-cymene in a well-stirred batch reactor. The results of the two activated catalysts, (VO)2P2O7 and VO(PO3)2 when used as powders in their pure form, showed a significant improvement in p-cymene oxidation rates with conversions up to 40 percent in 3-4 h reaction time with a TCHP selectivity of 75-80 percent. The (VO)2P2O7 catalyst showed better oxidation rates and selectivity when compared to the VO(PO3)2 catalyst obtained from the VO(H2PO4)2 precursor. The (VO)2P2O7 catalyst was supported on a stainless steel plate and the coated plate used to study the long-term stability and catalytic perfornance of the catalyst during p-cymene oxidations in a batch reactor. Comparable oxidation rates and TCHP selectivity were obtained with the stainless steel coated VPO catalyst when compared to the “free powder” (VO)2P2O7 catalyst. The results also showed that the stainless steel coated catalyst displays a slow, yet significant deactivation over extended reaction periods (250 h onstream). Characterization of the exposed (VO)2P2O7 catalyst to p-cymene oxidation conditions by…

▼ In the first part of this work, the reaction between cis- and trans-2-butenes and oxygen atoms was studied at room temperature in a flow reactor in the essential absence of molecular oxygen. Products were mainly analysed by gas chromatography. These reaction products were found to consist of hydrocarbons and oxygenated products in the ratio of approximately 2:1. The hydrocarbon products were mainly ethane, some ethylene, a little propane and isobutane, and trace amounts of methane, n-butane and isobutene. The oxygenated products were mainly acetaldehyde and propanal, some cis- and trans-2, 3-butene oxide, acetone, isobutanal, butanone-2 and traces of other products. Peroxides were also detected. Cis-trans isomerisation, previously unobserved by other workers, was found to occur during the course of the oxidation reaction. The disappearance of the oxygen atoms could not be accounted for by the amount of oxygenated products nor by the disappearance of the 2-butene, as observed by several previous authors. The reaction order for the rate of production of the various products and for the rate of disappearance of the 2-butene was found not to be simply unity with respect to each of the reactants 2-butene and oxygen atoms. The formation of products is explained in terms of an initial oxygen atom attack at the 2-butene to form a biradical [formula omitted] which is thought to decompose in one of three ways: [formula omitted]. Other products are formed through the interaction of the radicals thus produced, and from the reactions between these radicals and the parent 2-butene. Ring closure occurs to produce epoxides. Cis-trans isomerisation is effected by rotation about the centre C-C bond in the biradical and subsequent scission of the C-0 bond. The disappearance of oxygen atoms is explained through an olefin-catalysed recombination of oxygen atoms via a complex (π or charge transfer) formation between 2-butene and the oxygen atom [formula omitted] or by way of a 4-centre reaction scheme involving the biradical [formula omitted]. The formation of peroxides is thought to be due to the reaction between the radicals present and molecular oxygen thus produced. In the second part of this work, the thermal oxidation of. cis- and trans-2-butenes by molecular oxygen was investigated in a conventional static system. Pressure-time studies were made at 289°C and at a total initial pressure of 51 mm Hg. Cool flames were observed at the end of an induction period when the ratio (po₂/p₂-butene) was greater than unity but not very large. When this ratio became very large, no cool flame was observed but the pressure-time curve took on a simple S-shape. When this ratio became less than unity, no pressure increase was detected at the end of the induction period. The relationship between the overall pressure increase and the initial pressure of 2-butene at a total initial pressure of 51 mm Hg was found to be ΔP/p₂-butene = 1.66 - 6.0xl0⁻² p₂-butene where ΔP is the overall pressure increase and p₂-butene the initial 2-butene…

Oxidation of unsaturated lipids is the most active chemical reaction leading to deterioration of food quality and shortening of shelf life. Lipid oxidation is known to be a free radical chain reaction driven by lipid peroxyl and alkoxyl radicals abstracting hydrogen atoms from neighboring molecules to form stable hydroperoxide intermediates and transfer a radical to a new molecule. In this process, products accumulate only after hydroperoxides decompose. However, this simplistic reaction fails to account for observed kinetics and compounds generated. Recently, a more complex reaction scheme for lipid oxidation was proposed which integrates traditional hydrogen abstraction with alternate reactions of peroxyl and alkoxyl radicals – internal rearrangement, double bond addition, scission, dismutation. The alternate reactions run simultaneously and in competition with hydrogen abstraction, and alter the overall picture of lipid oxidation under different conditions. This dissertation research seeks to provide experimental proof of principle that these alternate pathways exist in lipid oxidation and have important consequences to timing and types of products developed. Lipid oxidation was studied in pure methyl linoleate incubated for 20 days under a range of conditions to investigate early reactions. Four types of major oxidation non-volatile products (conjugated dienes, hydroperoxides, epoxides, and carbonyls) were measured to determine product distributions and impact of reaction conditions on pathways. Two observations supported activity of reaction pathways other than hydrogen abstraction. First, epoxides were the dominant product under all conditions, with levels higher than hydroperoxides and in some cases almost as high as conjugated dienes. Second, all products began accumulating immediately at start of oxidation, although at different rates. Carbonyls were produced at much lower levels than other products. Coordinated analyses of volatile products suggested that these unusual patterns could be explained by competitive activity of two alternate reactions: 1) peroxyl radicals add to double bonds, forming a dimer that decomposes to an epoxide and an alkoxyl radical which can either form more epoxides or undergo scission to carbonyl products; 2) alkoxyl radicals add to an adjacent double bond to form epoxides and transfer the free radical down chain to a new site. Environmental conditions mostly affected initial oxidation rates.

▼ Metal-oxo species constitute an important type of metal-ligand multiple-bonded complexes and play a key role in metal-catalyzed/mediated oxidation reactions including oxidation processes in biological systems. This thesis describes the synthesis, characterization, electrochemistry and reactivity or catalytic properties of a number of iron and ruthenium complexes supported by nitrogen atom donor neutral multidentate ligands, with particular reference to the formation, spectroscopic characterization and reactivity studies of iron- and ruthenium-oxo species including an oxoiron(IV) ligand cation radical species and a cis-dioxoruthenium(VI) complex. Firstly, a series of iron(III) complexes supported by a combination of neutral tridentate and mono-anionic bidentate ligands were synthesized, and their catalytic properties for oxidation of alkanes with Oxone were examined. [(Me3tacn)FeIII(Cl-acac)Cl]ClO4 (Me3tacn = 1,4,7-trimethyl-1,4,7-triazacyclononane; Cl-acac = 3-chloro-acetylacetonate) catalyzed the oxidation of ethane and propane with Oxone at room temperature for 30 min to give oxidized products with total turnover number (TON) of 3.0 and 20.4 respectively; oxidation of cyclohexane afforded cyclohexanol and cyclohexanone with total TON up to 41 for a 5-min reaction. 18O-Labeling experiments, kinetic isotope effects on cyclohexane oxidation, and log krel vs. CH bond dissociation energy plot suggest the involvement of a high-valent oxoiron intermediate. A reaction mechanism on alkane oxidation reminiscent of the Cytochrome P-450 chemistry is proposed, which involves hydrogen atom abstraction followed by rapid oxygen atom rebound. Various spectrometric/spectroscopic studies by ESI-MS, EPR and UV-Vis, and also DFT calculations, on the reaction intermediate point to [(Me3tacn)FeIV({Cl-acac}•+)(O)]2+ as the active species in the catalytic oxidation of hydrocarbons. Secondly, a new method for the synthesis of ruthenium complexes bearing pyridylmethyl- and/or quinolyl-amine is described. This method has been utilized to synthesize the cis-diaquoruthenium(II) complexes of different chiral ligands including BQCN (N,N-dimethyl-N,N-di(quinolin-8-yl)cyclohexane-1,2-diamine) and its derivative Me2BQCN. Electrochemical studies show that cis-[(PDP)RuVI(O)2]2+ (PDP = 1,1-bis(pyridin-2-ylmethyl)-2,2-bipyrrolidine) is a strong oxidant with Ef = 1.13 V vs. SCE and a strong H-atom abstractor with a calculated DO–H = 90.8 kcal/mol. The catalytic activity of Ru(PDP) complexes toward oxidation of water, alkanes or alkenes was examined. In alkene oxidation with sodium periodate, reaction monitoring by ESI-MS revealed facile C=C bond cleavage. Using cerium(IV) ammonium nitrate as the oxidant, cis-[(PDP)RuII(OH2)2](OTs)2 catalyzed the oxidation of unactivated C–H bonds (e.g. ethane) with bond dissociation energies up to 100.5 kcal/mol. Finally, the electrochemistry of [(L-N4Me2)FeIIICl2]ClO4 (L-N4Me2 = N,N-dimethyl-2,11-diaza[3.3](2,6)pyridinophane), in both aqueous and non-aqueous media, has been established. In aqueous…

▼ Protein arginine methylation is an abundant post-translational modification catalyzed by protein arginine methyltransferases (PRMTs). Arginine methylation plays important roles in a variety of cellular pathways and human diseases. PRMT1, the predominant PRMT, catalyzes approximately 85% of all protein arginine methylation in vivo. While many details of how PRMT1 functions have been uncovered through the past two decades, there are many details which remain unclear, including how arginine methylation is regulated, how PRMT1 binds substrates, and what role PRMTs play in RNA surveillance. Our recent data presented in this thesis showed that reduction of the PRMT1 enzyme, following recombinant expression and purification, changes both enzymatic activity and oligomeric state. A cysteine residue(s) was found to be responsible for the observed redox chemistry in PRMT1 and at least one parameter in the kinetic mechanism, S-adenosylmethionine (AdoMet) binding, was faster with a reduced enzyme. This work suggests exciting potential for the regulation of PRMTs in vivo by oxidative stress. In addition to studying the effects of reduction/oxidation on PRMT1, a foundation for future experiments was laid. These experiments investigate substrate recognition by PRMTs and what the role arginine methylation may play in RNA processing and surveillance. To better understand how PRMTs selectively bind a wide variety of substrates, I have designed and preliminarily characterized several Hmt1 (the S. cerevisiae homologue of PRMT1) variants. These variants will be used for crystallization trials of a homogeneous complex, containing Hmt1, AdoMet, and a peptide substrate, capable of revealing specific chemical interactions between Hmt1 and the peptide substrate. To further our understanding of Hmt1's role in RNA processing and surveillance, particularly in RNA degradation pathways, I extracted yeast RNA from both wild type and Hmt1-null cells. The RNA was probed using a S. cerevisiae whole-genome microarray. This analysis revealed that Hmt1 exhibits statistically significant effects in several broad areas including molecular function, biological processes, cellular components, and some KEGG pathways. The presented studies have revealed the exciting potential for an in vivo regulatory mechanism of PRMT1 and each study is primed for further investigation both in vivo and in vitro.

▼ Surface modification is a process that is applied to the surfaces of titanium substrates in order to improve the biocompatibility after implanting in the body. Two methods were used in the present work: Anodisation and gel oxidation. Anodisation was performed at room temperature in strong mineral acids (sulphuric acid (H2SO4) and phosphoric acid (H3PO4)), an oxidising agent (hydrogen peroxide (H2O2)), mixed solutions of the preceding three, and a weak organic acid mixture (β-glycerophosphate + calcium acetate). The parameters used in anodisation were: Concentrations of the electrolytes, applied voltage, current density, and anodisation time. Gel oxidation was carried out by soaking titanium substrates in sodium hydroxide (NaOH) aqueous solutions at different concentrations (0.5 M, 1.0 M, 5.0 M, and 10.0 M) at 60°C for 24 h, followed by oxidation at 400°, 600°, and 800°C for 1 h.Conceptual models representing changes in the microstructure as a function of the experimental parameters were developed using the anodisation data. The relevant parameters were: Applied voltage, current density, acid concentration, and anodisation time: The model for anodisation using the strong acid (H2SO4) illustrates the growth rate of the film, identification of the threshold for the establishment of a consistent microstructure, and prediction of the properties of the film. For the oxidising agent (H2O2), two models were developed: Current-control and voltage-control, the applicability of which depends on the scale of the current density (high or low, respectively). These models are interpreted in terms of the coherency/incoherency of the corrosion gel, arcing, and porosity. The model for the strongest acid (H3PO4) is similar to that of H2O2 in current-control mode, although this system showed the greatest intensity of arcing and consequent pore size. Anodisation in mixed solutions uses Ohms law to explain four stages of film growth in current-control mode. These stages describe the thickness of the gel, its recrystallisation, and the achievement of a consistent microstructure. Anodisation in weaker organic acids allows the most detailed examination of the anodisation process. Both current density and voltage as a function time reveal the nature of the process in six stages: (1) instrumental response, (2 and 3) gel thickening, (4) transformation of the amorphous gel to amorphous titania, (5) recrystallisation of the amorphous titania, and (6) subsurface pore generation upon establishment of a consistent microstructure.Gel oxidation was done at low and high NaOH concentrations followed by oxidation. Three models were developed to represent the gel oxidation process: (1) Low concentration, (0.5 M and 1.0 M NaOH), (2) Medium concentration (5.0 M NaOH), and (3) high concentration (10.0 M NaOH). For the low concentrations with increasing temperature, the model involves: (1) amorphous sodium titanate forms over a layer of amorphous anatase and (2) a dense layer of rutile forms. For the high concentrations with… Advisors/Committee Members: Sorrell, Charles, Materials Science & Engineering, Faculty of Science, UNSW.
