▼ Colloidal particles with directional interactions that self-assemble into pre-defined microstructures have the potential to serve as the foundation for a new generation of micro- and nano-structures of remarkable complexity and precision. Dipolar colloid particles tend to align end-to-end and self-assemble into variety of micro- and nano-structures ranging from co-crystals of novel symmetry, to open networks (gels) of cross-linked chains of particles. Quadrupolar colloid particles also tend to self-assemble in a wide variety of structural motifs including sheets, tubes and shells depending upon external conditions. We use molecular dynamics computer simulation to explore the self-assembly, structure, crystallization and/or gelation of systems of colloid particles with permanent dipole moments or quadrupole moments immersed in a high-dielectric solvent. Particle-particle interactions are modeled with discontinuous potentials in order to take advantage of discontinuous molecular dynamics (DMD), a fast simulation technique that is very computationally efficient. We first calculate the phase diagram of monodisperse system of dipolar colloid particles using DMD in the temperature-packing fraction plane. Several types of phases are found in our simulations: ordered phases including face centered cubic (FCC), hexagonal close packing (HCP) and body centered tetragonal (BCT) at high packing fractions, and fluid, string-fluid and gel phases at low packing fractions. The very low volume fraction gel phases and the well ordered crystal phases are promising for advanced materials applications. We then examine how the phase diagram changes upon varying the sizes of the two species as well as their dipole moments. The phase diagrams of an equimolar binary mixture of dipolar colloid particles with different diameter ratios and different dipole moment ratios are calculated in the temperature-volume fraction plane. These systems exhibit six distinct phases: isotropic fluid, string-fluid, gel, FCC, HCP, BCT, and ten coexisting phases: Fluida + String-fluidb, Fluida + Gelb, String- Fluida + Gelb, Gela + BCTb, FCCa + FCCb, FCCa + HCPb, FCCa + FCCb+ Fluid, HCPa + HCPb, BCTa + BCTb, BCTa + BCTb + large voids depending upon size ratio and dipole moment ratio. An interesting aspect of these phase diagrams is the appearance of co-crystals containing large and small dipolar colloid particles at size ratio equal to 0.414. Even more interesting is the appearance of two unique bicontinuous gel structures - the first gel consists of two independent, but interpenetrating, networks of cross-linked chains formed by particles with high dipole moment and chains formed by particles with low dipole moment. The second type of gel consists of network of cross-linked chains formed by particles with high dipole moment, while particles with low dipole moment form a sheath around the chains. Such bicontinuous gels may have unusual rheological and transport properties such as multiple yield stresses and multiple percolation temperatures and could form the… Advisors/Committee Members: Carol K.

Grâce à ses propriétés uniques, le groupement pentafluorosulfanyle (SF5) a récemment retenu beaucoup d'attention. Ce substituant encombrant, hautement lipophile et électro-attracteur est souvent considéré comme un "super groupement trifluorométhyl". Aujourd’hui, la chimie de groupement SF5 est un domaine de la chimie du fluor qui se développe rapidement, et les méthodologies de synthèse des nouveaux « building-blocks » pentafluorosulfanylés sont constamment développées. Néanmoins, les méthodes permettant l'introduction du groupement SF5 dans les hétérocycles restent encore assez limitées. L’objectif de cette thèse était de synthétiser des nouveaux « building-blocks » pentafluorosulfanylés, d’une part, et de développer des nouvelles approches synthétiques, conduisant à des hétérocycles azotés originaux, substitués par un groupement SF5, d’autre part. Dans la première partie de notre travail, nous avons développé une synthèse en 4 étapes, conduisant à de nouveaux esters et amides acryliques substitués par un groupement SF5, à partir des dérivés commerciaux de l’acetate allylique. En utilisant la même stratégie, quelques nouveaux allylsilanes pentafluorosulfanylés ont été synthétisés. Nous avons aussi développé une réaction d’allylation des aldéhydes, catalysée par indium, en utilisant le bromure SF5-allylique, conduisant aux alcools alpha- et gamma-homoallyliques correspondants.Dans la deuxième partie, deux stratégies différentes pour la synthèse de nouveaux hétérocycles SF5-substitués, ont été explorées. La première était la fluoration directe des thiols ou disulfures hétérocycliques, suivant la procédure de Umemoto. La deuxième approche était basée sur les réactions de cycloaddition de nos "building-blocks" pentafluorosulfanylés. Ainsi, nous avons développé avec succès la synthèse des premières pyrrolidines et isoxazolidines pentafluorosulfanylées. Enfin, des post-fonctionnalisations des SF5-pyrrolidines ont été effectuées, conduisant aux plusieurs "plateformes" pentafluorosulfanylées qui pourraient être facilement incorporées dans les molécules d’intérêt biologique.

Due to its unique properties, the pentafluorosulfanyl (SF5) group has recently reached much attention. This bulky, highly lipophilic and electron-withdrawing substituent is often called as a “super-trifluoromethyl group”. Currently, the SF5-chemistry is becoming a fast growing field of the fluorine chemistry and the new pentafluorosulfanylated building-blocks are under continuous development. Nevertheless, the methods for the introduction of the SF5-group into heterocycles remain still quite limited.The aim of this thesis was to synthesize new pentafluorosulfanylated building-blocks, on the one hand, and to develop new synthetic approaches leading to original pentafluorosulfanylated nitrogen-containing heterocyles, on the other hand.In the first part of our work, we have developed an efficient four-step synthesis of new SF5-acrylic esters and amides, starting from commercially available allyl acetate derivatives. Using the same strategy, several new…

▼ Our group has developed different nanomachines over the years, while some of them are designed to perform in solution phase, a group of molecules termed nanocars were designed to specifically operate on solid surfaces. In this work, wheels, designed to yield better surface and molecule interaction for our studies is synthesized. In the past we have used mainly C60 fullerene wheels for our nanocars molecules. But after we decided to integrate a light activated motor into the nanocars, the fullerene wheels had to be phased out since the fullerene is known to quench the light energy used to actuate the motor. Our group then primarily utilized the p-carborane wheel as it does not show the same quenching effect with the motors. To improve the mobility and diffusion constant of the nanocars, a new generation of wheels was developed, featuring adamantane. A four-wheeled and a three-wheeled fluorescent nanocar was synthesized and monitored, showing enhanced performance to the p-carborane wheeled analogue, which we attribute to the lower surface/wheel interactions. The adamantane wheels were then used to synthesize two nanocars with both a fluorescent 4,4-difluoro-4-bora-3a,4a-diaza-s-indacene (BODIPY) core and a MHz frequency light-activated unidirectional rotary motor, one molecule that is angular and expected to operate in circles and one that is straight and expected to primarily move in a single direction. Preliminary experiments have been conducted and show promising results. While the BODIPY core does quench some of the energy that was supposed to be directed to the motor, the motor still accelerates the nanocar to increase the diffusion constant. The same principle was used to synthesize a molecule with BODIPY core and motor (but without wheels) that could operate in solution. Finally, a two-wheeled nanocar was synthesized with a water soluble extension that could fit into cyclodextrin (CD) cavities and serve as wheels. This nanocar is expected to have very high surface interaction and could be used as to modify surface interactions and the resulting mobility and diffusion constants of nanocars on surfaces.

Os compostos mesoiônicos são heterocíclicos notáveis por apresentar as mais diversas propriedades biológicas, físicas e químicas. São definidos como betaínas heterocíclicas planas e não aromáticas estabilizadas por deslocalização de elétrons. Através de uma reação in situ de cicloadição/cicloreversão 1,3-dipolar obtiveram-se dois mesoiônicos, MI-1.1 e MI-1.2, através da interconversão do sistema 1,3-oxazólio-5-olato (Munchnonas) para 1,3-tiazólio-5-tiolato. Uma reação de substituição nucleofílica com excesso de iodeto de metila, CH3I, promoveu a primeira modificação no sistema mesoiônico sendo transformados de base livre para sais iodatos S-metilados formando os derivados mesoiônicos, MI-2.1 e MI-2.2. Estes sofreram uma reação de ciclodesidratação na presença de anidrido acético obtendo-se dois mesoiônicos do sistema 1,3-diazólio-5-tiolato, MI-3.1 e MI-3.2, que por sua vez foram alquilados novamente e originaram dois derivados em forma de sais iodatos S-metilados, MI-4.1 e MI-4.2. Sendo os mesoiônicos e seus derivados: MI-2.1, MI-2.2, MI-3.1, MI-3.2, MI-4.1 e MI-4.2 inéditos na literatura. Suas estruturas foram elucidadas por meio de técnicas espectroscópicas de RMN 1H e 13C e infravermelho através de uma análise comparativa com estruturas já existentes.

Mesoionic compounds are notable heterocyclic for having the most diverse biological properties, physical and chemical properties. Are defined as flat and non-aromatic heterocyclic Betaines stabilized by electron delocalization. Through an in situ cycloaddition/cicloreversion 1,3-dipolar were obtained two mesoionic, MI-1.1 and MI-1.2 through of the interconversion system 1,3-oxazólio-5-olato (Munchnonas) for 1,3-tiazólio-5-tiolato. A nucleophilic substitution reaction with excess methyl iodide, CH3I, promoted the first modification to the mesoionic system were changed of free base to iodates salts, S-methylated forming derivatives mesoionic, MI-2.1 e MI-2.2. These underwent a cyclodehydration reaction in the presence of acetic anhydride yielding two mesoionic system 1,3-diazolium-5-thiolate, MI-3.1 and MI-3.2, which in turn were alkylated again and originated two derived in the form of iodates salts S-methylated, MI-4.1 and MI-4.2. As the mesoionic and its derivatives: MI-2.1, MI-2.2, MI-3.1, MI-3.2, MI-4.1 and MI-4.2 and unpublished literature. Their structures were elucidated by spectroscopic techniques for RMN 1H and 13C and infrared light through a comparative analysis with existing structures.

Dans ce mémoire nous présentons plusieurs études expérimentales des propriétés magnétiques d’un condensat de Bose-Einstein de Chrome chargé dans un réseau 3D, en nous focalisant sur les effets associés aux interactions dipolaires. Nous montrons que dans un réseau 3D, la relaxation dipolaire est un processus résonant du fait de la réduction de la densité d’états orbitaux accessibles. Les résonances sont observées à des champs magnétiques Bres tels que l’énergie Zeeman relâchée soit égale à l’énergie nécessaire à exciter les atomes dans une bande d’énergie supérieure du réseau. Nous pouvons inhiber ce processus en appliquant un champ différent de Bres. L’analyse des résonances a permis de sonder la structure de bande 3D du réseau, ainsi que la mise en évidence de l’effet des interactions entre atomes. Nous avons étudié la dynamique d’échange de spin dans un réseau 3D. Nous présentons en particulier la première observation d’échange de spin entre atomes localisés dans des sites séparés. Ces études permettent une exploration nouvelle du magnétisme en réseau. En variant la profondeur du réseau, nous étudions ces effets dans le régime superfluide, bien décrit par une théorie de champ moyen, et dans le régime fortement corrélé, dont la description théorique est difficile. Enfin, nous étudions l’évolution de deux spins géants interagissant par interaction dipolaire. Le condensat initialement divisé en deux, les atomes des deux nuages sont préparés dans des états de spin opposés formant ainsi deux spins géants ±3xN. Nous montrons que toute dynamique de spin est énergétiquement inhibée pour de grands spins ce qui est bien reproduit par une théorie classique.

This Thesis reports on several experimental studies of magnetic properties of a Chromium Bose-Einsteincondensate loaded into a 3D optical lattice, focusing on the effects induced by dipolar interactions.We show that in a 3D lattice dipolar relaxation is a resonant process due to the reduction of the density ofaccessible orbital states. These resonances are observed for magnetic fields Bres such that the Zeeman energyreleased matches an excitation towards higher-energy bands of the lattice. We can thus inhibit those processes byapplying a field different from Bres. Analyses of the resonances allowed us to probe the lattice 3D band structureas well as to demonstrate the effects of local interactions between atoms.We study spin exchange dynamics in a 3D lattice. We especially observed for the first time spin exchangebetween atoms localized in different lattice sites mediated by dipolar interactions. These studies are the firststep toward a new exploration of magnetism in lattice. Varying the depth of the lattice we study these effects inthe superfluid regime, well described by mean filed theories, as well as in the strongly correlated regime, whosetheoretical description is still challenging.Finally, we study the evolution dynamics of two giant spins interacting through dipolar interactions. Thecondensate being initially splitted in half, atoms from the two clouds are…

In this work we consider a bipartite system consisting of magnetic dipoles, initially characterized by product-states uncorrelated until the dynamics of evolution is established by magnetic dipole interaction. We reproduce the dynamic behavior of the entanglement produced by the magnetic dipole interaction through its temporal dependence, connection with local quantum coherences or symmetries of initial states and interaction parameters, thus establishing criteria that extremize the entanglement. We also investigated the entanglement production capacity of the magnetic dipole interaction for some classes of states with lower purities, with and without initial entanglement, thus identifying relevant aspects between purity, symmetry and necessary local quantum coherences. We show, above all, that some classes of partially entangled states can preserve or generate maximum entanglement under magnetic dipole interaction for different instants of time.

Neste trabalho consideramos um sistema bipartido constituído por dipolos magnéticos, inicialmente caracterizados por estados tipo produto descorrelacionados até que a dinâmica de evolução seja estabelecida pela interação dipolar magnética. Reproduzimos o comportamento dinâmico do emaranhamento produzido pela interação dipolar magnética através de sua dependência temporal, conexão com coerências quânticas locais ou simetrias de estados iniciais e parâmetros de interação, estabelecendo assim critérios que extremizam o emaranhamento. Também investigamos a capacidade de produção de emaranhamento da interação dipolar magnética para algumas classes de estados com purezas menores, com e sem emaranhamento inicial, identificando assim aspectos relevantes entre pureza, simetria e coerências quânticas locais necessárias. Mostramos sobretudo, que algumas classes de estados parcialmente emaranhados podem preservar ou gerar o máximo emaranhamento sob interação dipolar magnética para instantes de tempo distintos.

The present dissertation describes a chemical methodology for the synthesis of three series containing fourteen new molecules of trifluoro(chloro)methyl substituted 1H-1,2,3-triazoles, which are structural analogues to the antiepileptic drug Rufinamide. The protocol used consisted in reactions of 1,3-dipolar cycloaddition of 2,6-difluorobenzyl azide and 4-alkoxy-4-alkyl(aryl/heteroaryl)-1,1,1-trifluoro(chloro)-3-alken-2-ones, where the 4-substituents are H, Me, Ph, 4-OMeC6H4, 4-NO2C6H4,4-FC6H4,2-Thienyle 4,4 -Biphenyl. The optimized reactios were carried-out in absense of solvente, in reaction times of 48 to 96 hours at 100-150°C and in yields of 30-75%. The reactions employing the 4-alkoxy-4-aryl(heteroaryl)-1,1,1-trifluoro-3-alken-2-ones 1and 2,6-difluorobenzyl azidedemonstrated a 4-substituent dependency of the enones precursors (above mentioned) and conducted to the formation of isomeric mixtures of 4-trifluoroacetyl substituted and/or 5-trifluoromethyl substituted triazoles in varying proportions, which were separated and purified by chromatographic columns. On the other hand, the reactions employing the 4-alkoxy-4-alkyl(aryl/heteroaryl)-1,1,1-trichloro-3-alken-2-ones and the same 2,6-difluorobenzyl azide produced exclusively a series of 4- trichloroacetyl substituted triazoles without the detection of the respective 5-trichloromethyl substituted regioisomer. The synthesized triazoles were characterized by 1H, 13C, uni- and two-dimensional NMR Spectroscopy techniques as HMQC, gas chromatography coupled to mass spectrometry (GC-MS), mono-crystal X-ray diffraction, high resolution mass spectrometry (HRMS) and their purity determined by CHN Elemental Analysis.

A presente dissertação descreve uma metodologia química para a síntese de três séries de 1H-1,2,3-triazóis trifluor(cloro)metil substituídos, totalizando quatorze moléculas inéditas, as quais são análogas estruturais do fármaco antiepiléptico Rufinamida. O protocolo consistiu na realização de reações de cicloadição 1,3-dipolares envolvendo 2,6-difluorbenzil azida e 4-alcóxi-4-alquil(aril/heteroaril)-1,1,1-trifluor(cloro)-3-alquen-2-onas, sendo os substituintes 4-alquila(arila/heteroarila) iguais a H, Me, Ph, 4-OMeC6H4, 4-NO2C6H4,4-FC6H4,2-Tienila e 4,4 -Bifenila. As reações otimizadas se processaram na ausência de solvente, em tempos reacionais de 48 a 96 horas a 100-150°C e levaram a rendimentos na faixa de 30-75%. As reações que utilizaram 4-alcóxi-4-aril(heteroaril)-1,1,1-triflúor-3-alquen-2-onase 2,6-difluorbenzil azida apresentaram uma dependência quanto a substituição da posição 4 das enonas precursoras (acima descritos) e conduziram à formação de misturas isoméricas de triazóis 4-trifluoracetil substituídos e/ou 5-trifluormetil substituídos em proporções variadas, as quais foram passíveis de separação e purificação por cromatografia em coluna. Por outro lado, as reações empregando 4-alcóxi-4-alquil(aril/heteroaril)-1,1,1-tricloro-3-alquen-2-onas e a mesma 2,6-difluorbenzil azida…

Nesta dissertação, apresentamos uma aplicação simples de RMN de 1H no domínio do tempo (TD-NMR) de baixo campo para caracterização de dinâmica molecular variando do regime intermediário ao rápido. O método se baseia no filtro dipolar seguido da aplicação do Mixed Magic Sandwich Echo(MSE), o qual denominamos DF-MSE. O filtro dipolar suprime os sinais oriundo de segmentos com mobilidade abaixo de kHz, de modo que somente segmentos móveis sejam detectados. Assim, a dependência com a temperatura da intensidade do sinal mostra diretamente a temperatura em que movimentos moleculares ocorrem ao atingirem taxas maiores que kHz. Para que não ocorra variação da intensidade com a temperatura, mas somente pelos movimentos moleculares, os sinais são normalizados por uma intensidade de referência obtida pela aquisição de DF-MSE sem aplicação do filtro dipolar. A intensidade normalizada DF-MSE pode ser descrita adequadamente por uma expressão analítica baseada na aproximação de Anderson-Weiss, de forma a permitir que parâmetros de ativação de movimentos sejam avaliados. Ademais, também propomos um método baseado na diferença entre sinais DF-MSE normalizados adquiridos com tempos de filtro distintos, permitindo assim quantificar a largura da ditribuição de tempos de correlação de uma forma independente. A aplicação geral foi testada de forma bem sucedida em polímeros monofásicos e multifásicos. De fato, o método apresentado é um prosseguimento da análise feita pelo MSE já presente na literatura, porém sondando movimentos mais rápidos e com uma forma aprimorada para avaliação de heterogeneidades de movimento.

In this dissertation, we present a simple NMR approach for characterizing intermediate to fast regime molecular dynamics using 1H time-domain NMR (TD-NMR) at low magnetic field. The method is based on a dipolar filter followed by a Mixed Magic Sandwich Echo and FID acquisition, which is symbolized DF-MSE. The dipolar filter suppresses the signals of segments presenting sub kHz mobility, so only signals from mobile segments are detected. Thus, the temperature dependence of the signal intensities directly evidences the onset of molecular motions with rates higher than kHz. In order to avoid temperature variation of the signal intensities other than that due to motions, the signals are normalized by a reference intensity obtained in a DF-MSE acquisition without the dipolar filter. The normalized DF-MSE intensity can be well described by an analytical function based on the Anderson-Weiss approach, so the activation parameters of the motion can be evaluated. Furthermore, we also propose a method based on the difference between normalized DF-MSE signals acquired with different dipolar filter times, which provide evaluation of the width of the distribution of correlation times in an independent fashion. The general approach was successfully tested in single and multiphase polymer systems. Indeed, the presented method is a follow up of the MSE analysis previously reported, but probing faster motions and with an improved way…

▼ This work presents the results of various investigations using various techniques of hyperpolarizing the nuclei of atoms. Hyperpolarization implies magnetic order in excess of the thermal order obtained naturally as described by Curie's law. The main portion of this work presents the results of a detailed experimental exploration of predictions arising from a new model of transverse nuclear spin relaxation in quantum systems, based on possible manifestations of microscopic chaos in quantum systems. Experiments have been carried out on a number of hyperpolarized xenon samples, each di ering in its relative percentage of xenon isotopes in order to vary the homonuclear and heteronuclear dipole couplings in the spin system. The experiments were performed under a variety of conditions in an attempt to observe the behaviors predicted by the model. Additionally, much more extensive measurements were made on a number of samples of solid CaF2 in both single crystal and powder forms. These samples, although thermally polarized, were observed with superior signal to noise ratios than even the hyperpolarized xenon solids, allowing for more precise measurements for comparison to the theory. This work thus contains the rst experimental evidence for the majority of the model's predictions. Additionally, this work contains the rst precise measurements of the frequency-shift enhancement parameters for 129Xe and krypton in the presence of spin-polarized Rb. The determination of these important numbers will be useful to many groups who utilize spinexchange optical pumping in their labs. This work built on the prior knowledge of a precise number for the frequency-shift enhancement parameter of 3He in Rb vapor. Finally, I detail work using NMR to detect nuclear-spin polarization enhancement in silicon phosphorus by a novel, photo-induced hyperpolarization technique developed by the Boehme research group at the University of Utah. Signiif cant nuclear polarization enhancements were observed by the Boehme group due to electron-photon interactions in semiconductor soilds; these enhancements were observed by their e ffects on the ambient electrons and measured with electron spin resonance techniques. The work described here details experiments to observe the enhanced nuclear polarization by directly measuring the intensity increase in an NMR measurement.

▼ The large number of inexpensive carboxylic acids found in nature has spurred research to convert carboxylic acids to an assortment of other functional groups for a range of purposes. To accomplish this, researchers employ a variety of strategies ranging from heat and heavy metals to biocatalysts. Ferulic acid decarboxylase (FDC1) from Saccharomyces cerevisiae is a member of the UbiD family of decarboxylase enzymes. The UbiD family of proteins consists of prenylated flavin (PrFMN)-dependent enzymes that catalyze the reversible decarboxylation of a wide variety of aromatic carboxylic acids. The UbiD family attracted interest as a biocatalyst to produce chemical feedstocks from renewable sources and as a potential target for antimicrobial research. The UbiD enzyme, FDC1, and its associated protein partner, PAD1, were identified as being responsible for the detoxification of aromatic carboxylic acids in fungi. How PAD1/FDC1 work together to facilitate the decarboxylation of toxic aromatic acids remains an open question. The genes encoding PAD1 and FDC1 were independently expressed in E. coli with the PAD1 homolog UbiX knocked out. Independently, FDC1 and PAD1 were unable to decarboxylate phenylacrylic acids. Moreover, PAD1 failed to decarboxylate any of the phenylacrylic acids by itself. In contrast FDC1 was able to recover its decarboxylase activity upon the addition of PAD1 or its homolog UbiX, indicating FDC1 was solely responsible for the decarboxylase activity. Co-expression of FDC1 and PAD1 coupled with the sole purification of FDC1 exhibited spectral characteristics of a reduced flavin in an aerobic system. This increased the kcat by 8-fold. The holo-FDC1 crystal structure (PDB 4ZAC) provided insight into the decarboxylation mechanism of FDC1. FDC1 was proposed to perform a unique and controversial 1,3-dipolar cycloaddition mechanism. To address the controversial nature of the proposed mechanism KIE and a Hammett analysis were utilized to ascertain whether FDC1 undergoes the proposed mechanism or a completely different mechanism. The solvent isotope effects, normal secondary isotope effects, and the negative slope of the Hammett analysis are consist with the rate-determining step being the breakdown of the PrFMN-product adduct through a non-concerted cyclo-elimination reaction, and provides evidence in favor of the novel 1,3-dipolar cycloaddition mechanism. The proposed mechanism involves the formation of a novel pentacyclic intermediate through a novel 1,3-dipolar cycloaddition mechanism between PrFMN and the β -γ double bond of the substrate, which serves to activate the substrate towards decarboxylation. In order to trap this hypothesized intermediate, a mechanism-based inhibitor 2-fluoro-2-nitro-vinylbenzene (FNVB) was used to trap the putative cyclo-addition intermediate. Upon incubating FNVB with FDC1, there was a red-shift in the flavin spectrum which is reminiscent of an uncharged N5, C4α dialkyl flavin adduct and is consistent with a 1,3-dipolar cycloadduct. Finally by pushing the… Advisors/Committee Members: Marsh, E Neil G (committee member), Palfey, Bruce Allan (committee member), Koutmou, Kristin (committee member), Walter, Nils G (committee member).

▼ We develop and apply meanfield methods to two systems of significant interest in cold atom physics. The first system, and the main subject of this thesis, is a gas of polarized dipoles, in which the particles have a long range anisotropic interaction. The second system is a toroidally trapped gas that interacts via short range interactions. Dipolar gases: We develop accurate techniques for dipolar Bose and Fermi gases accounting for both direct and exchange interactions. We detail an efficient numerical implementation of the meanfield treatment. We study the thermodynamic and the first and second order correlation properties of the system. We find that exchange interactions cause the correlation functions to be anisotropic in the low temperature regime. We also find that many uniform gas thermodynamic predictions, for which direct interaction effects vanish, are qualitatively unreliable for trapped systems, most notably for oblate traps. Using Hartree-Fock theory and analytic approximations, we examine the magnetostrictive position and momentum space distortions that occur in harmonically confined dipolar Bose and Fermi gases. The Bose gas momentum distribution distorts in the opposite sense to that of the Fermi gas. By relating exchange effects to short range correlations between the particles we discuss the energetic origin of this difference. Introducing local momentum distortion fields, we develop a practical Hartree-Fock theory in which exchange effects are described by a local effective potential. This theory is applicable at zero and finite temperature, and is in excellent agreement with full Hartree-Fock calculations. Contact gases: We show how considerable simplification of numerical results and analytical derivations can be achieved in the local density approximation using a variety of density of states techniques. We examine the process of isentropic loading of a Bose or Fermi gas from a harmonic trap into the scale invariant toroidal regime that exhibits a high degree of system invariance when increasing the radius of the toroid. For bosons a regime of cooling is identified and we find that the Fermi gas is subjected to irreducible heating during loading, caused by the loss of one degree of freedom for thermalization.

▼ The work of this thesis concerns the properties of a Bose gas of polarised dipoles that have long-range and anisotropic interactions. Our work is divided into two parts. First, the stability of a dipolar Bose gas at finite temperature (both above and below the critical Bose-Einstein condensation (BEC) temperature Tc). Second, the fluctuations of a dipolar BEC at zero and small finite temperature (T ≪ Tc) in a regime where rotonic excitations emerge. Part I: Stability of a Trapped Finite Temperature Dipolar Bose Gas: Above Tc we implement a semiclassical Hartree-Fock theory and characterise the dependence of the stability boundary on temperature, trap geometry and the strength of the dipole-dipole interaction and contact interaction. We find that stability is greatly enhanced above Tc and that trap geometry continues to play a key role. Furthermore, we find that for oblate traps a novel double instability feature emerges. To extend our stability analysis to the low temperature regime, T < Tc, we develop a beyond semiclassical Hartree theory. We use this to characterise the stability boundary as a function of geometry. Interestingly, we find large beyond semiclassical effects above Tc for prolate trapping geometries. We characterise thermal effects on biconcave condensate states. Part II: Rotons and Fluctuations in a Trapped Dipolar Condensate: To study density fluctuations we implement a numerical scheme to solve the Gross-Pitaevskii equation and the Bogoliubov de Gennes equations. We find that the phonon and roton gases spatially separate and we characterise the role of the anomalous density on the density fluctuations of the thermally activated rotons. We develop a numerical scheme that calculates number fluctuations within cells of various shapes and sizes, and find a strong peak in the fluctuations when the cell size is around half the roton wavelength, which should be detectable by current experiments. By tailoring the cell shape we predict that experiments should be able to detect the effects of individual roton modes. For the study of zero temperature fluctuations we deploy the Gross-Pitaevskii and Bogoliubov de Gennes equations to calculate the dynamic and static structure factors for a highly oblate BEC. We find a clear signature of the roton gas dispersion relation within the structure factors. This signature should be detectible in current experiments using Bragg spectroscopy.

▼ In 2005 Kobayashi reported the isolation and absolute stereochemistry of Citrinadin A (1) and Citrinadin B (2), novel secondary metabolites of the marine fungus Penicillium citrinum. In addition to their interesting molecular architecture, the citrinadins are biologically active. Both exhibit cytotoxicity against murine leukemia L1210 (IC50 6.2 and 10 μg/mL respectively), and 1 has shown activity against human epidermoid carcinoma KB cells (IC50 6.2 μg/mL). Synthesis of 1 and 2 would allow for further testing of their biological activity and remains the best way to confirm their assigned structures. While, no total synthesis of either natural product has been reported to date, two synthetic approaches toward the citrinadins have been disclosed by Martin and Sorensen. Efforts to synthesize 1 and 2 in the Wood laboratory are based upon a convergent (3+2) dipolar cycloaddition reaction between a spiro-oxindole dipolarophile and a nitrone, where two diastereomeric isoxazolidine cycloadducts are formed. Using the undesired cycloadduct, exploratory studies toward a synthesis of 2 were conducted, resulting in the synthesis of the C3-epi-Citrinadin Core (±)-96. Elaboration of the desired cycloadduct then led to a synthesis of the ent-Citrinadin Core (+)-100. In order gain to access 2, a C7-functionalized spiro-oxindole dipolarophile was employed in the cycloaddition; however, elaboration of the desired C7-functionalized cycloadduct to ent-2 may result in a structural reassignment of 2. Preliminary results suggest that spectral data for the C21-epi-ent diastereomer of 2 (175) match the data reported by Kobayashi for Citrinadin B (2) itself. In an effort to gain access to 1, a (3+2) cycloaddition strategy utilizing a C14-functionalized nitrone was explored. Following the synthesis of three nitrone precursors, a one-pot nitrone formation / (3+2) cycloaddition reaction was developed and one of the cycloadducts was successfully advanced to a key ring-fusion epoxide. Elaboration of this advanced intermediate is expected to eventually provide a total synthesis of Citrinadin A (1). Advisors/Committee Members: Wood, John L. (advisor), Williams, Robert M.

▼ Iminosugars are naturally occurring polyhydroxylated alkaloids. These natural mimics of carbohydrates have found clinical use with their biological activity mainly attributed to their inhibition of glycoprocessing enzymes. The background to this thesis and the intramolecular tandem allylic azide rearrangement – Huisgen cycloaddition are discussed in Chapter 1. Chapter 2 describes the synthesis of iminosugar derivatives from D-glucono-[delta]-lactone which is an extension of work carried out previously in the Murphy group for the preparation of 1-deoxyiminosugars. This route was particularly successful in the highly stereoselective preparation of iminosugars fused to triazoles from an intramolecular rearrangement-cycloaddition between azide and alkyne groups. However the rearrangement-cycloaddition between azide and alkene groups based on intermediates with the glucose configuration suffered from poor yields. An alternative route using a zinc-mediated reductive fragmentation reaction from a variety of commercially available sugars to prepare allylic azide precursors was next explored. This is discussed in Chapters 3-5, which also describe the rearrangement-cycloaddition reactions of these intermediates which lead to iminosugars based on glucose, mannose and galactose. The importance of a conformational constraint to achieve the cycloaddition emerged. Again, the cycloaddition of the glucose intermediates was affected by poor yields. However, results with the mannose and galactose derivatives were more promising. The stereoselectivity was assigned using NMR coupling constants (JH1-H2 and JC1-H1 values), NOEs, X-ray crystallography and comparisons with analytical data for compounds already described in the literature. The stereoselectivities were rationalised with the aid of models built using molecular mechanics. The synthesis of a natural C-glycoside iminosugar was achieved. Overall this thesis demonstrates that an allylic azide rearrangement carried out in tandem with Huisgen cycloaddition is diastereoselective in ring formation and should be useful in organic chemistry.

▼ The focus of the novel research reported in this thesis is the labelling of nucleic acids by catalyst-free 1,3-dipolar cycloaddition reactions. Both nitrile oxide-alkyne cycloadditions (NOAC) and strain-promoted azide-alkyne cycloadditions (SPAAC) were explored. The possiblitity for ‘pre-synthetic’ functionalisation was demonstrated using non-nucleosidic phorphoramidite building blocks generated by NOAC. Three isoxazole phosphoramidites were prepared. Following in situ generation of the nitrile oxides from 1,2-, 1,3- or 1,4-disubstituted hydroxyethoxybenzaldehyde oximes and highly regioselective cycloadditions to a simple alkyne, the isomeric isoxazoles were obtained in excellent yields. Functional group interchange of the pendant hydroxy group to a phosphoramidite functionality facilitated coupling to DNA both by manual and instrument controlled solid phase DNA synthesis. Photoresponsive DNA, incorporating isomeric isoxazole-linked azobenzene moieties, was prepared by ‘post-synthetic’ modification of alkyne-functionalised oligonucleotides by NOAC. The compatibility of the azobenzene functionality with NOAC protocols was first confirmed with small molecule examples; the resulting cycloadducts were characterised by NMR spectroscopy and mass spectrometry (MS). Oligonucleotides incorporating azobenzene moieties at either the 5’- or the 3’- termini, or at an internal position, were subsequently synthesised and the photochemical and kinetic properties of selected examples were determined. A relationship was found between the thermodynamic and photochemical properties of the modified oligonucleotides and the substitution pattern on the aryl rings of the azobenzene moiety. DNA and 2’-OMe RNA sequences conjugated to a variety of chemically and biologically significant ligands were prepared by solid-phase SPAAC. A strained-cyclooctyne phosphoramidite was first conjugated to the 5’-terminus of oligonucleotides. Several azide labels were prepared, including benzyl, cinnamyl, biotinyl, cholesteryl and fluoresceinyl. Conjugation was clean and efficient in all cases. Oligonucleotides were characterised by HPLC and MALDI-TOF MS.

▼ Nanomagnets that exhibit only two stable states of magnetization can represent digital bits. Magnetic random access memories (MRAM) store binary information in such nanomagnets, and fabrication of dense arrays of nanomagnets is also under development for application in hard disk drives (HDD). The latter faces the challenge of avoiding magnetic dipole interactions between the individual elements in the arrays, which limits data storage density. On the contrary, these interactions are utilized in the magnetic quantum-dot cellular automata (MQCA) system, which is a network of closely spaced, dipole-coupled, single-domain nanomagnets designed for digital computation. MQCA offers very low power dissipation together with high integration density of functional devices, as QCA implementations do in general. In addition, MQCA can operate over a wide range of temperatures from zero Kelvin to the Curie temperature. Information propagation and negation have previously been demonstrated in MQCA. In this dissertation room temperature operation of the basic MQCA logic gate, i.e. the three-input majority gate, is demonstrated for the first time. The samples were fabricated on silicon wafers by using electron-beam lithography for patterning thermally evaporated ferromagnetic metals. The networks of nanomagnets were imaged by magnetic force microscopy (MFM), with which magnetization states of the individual nanomagnets were distinguished and mapped. Magnetic dipole-ordering in the networks was investigated in different samples. Average ordering lengths were calculated by statistical analysis of the MFM images that were taken after several independent demagnetization processes. The average ordering length was found to be dependent on shape and size of the nanomagnets, and it was limited by defects introduced during fabrication. The majority gate was demonstrated by employing 30 nm thick NiFe polycrystalline nanomagnets with 70 nm x 120 nm lateral sizes. Inputs were provided by additional nanomagnets fabricated together with the gate, and the operation was tested by MFM. The work presented here is an experimental proof of concept for the MQCA. The theoretical calculations can be found in the dissertation of Gyrgy Csaba.# <h1>Gyrgy Csaba, “Computing with field-coupled nanomagnets," PhD dissertation, University of Notre Dame, 2004.</h1> Advisors/Committee Members: Debdeep Jena, Committee Member, Jacek Furdyna, Committee Chair, Thomas Kosel, Committee Member, Wolfgang Porod, Committee Member, Gary H Bernstein, Committee Member, Vitali Metlushko, Committee Member.

Dans le cadre de cette thèse, j’ai étudié le refroidissement et le piégeage d’un gaz d’atomes de dysprosium dans des potentiels lumineux. Cet atome lanthanide possède dans son état électronique fondamental un moment magnétique très élevé, permettant l’exploration du domaine des gaz dipolaires ultrafroids. Ce caractère dipolaire enrichit la gamme des phénomènes physiques réalisés expérimentalement, en tirant avantage de la nature anisotrope et à longue-portée de l’interaction entre dipôles magnétiques. De plus, grâce à sa structure électronique riche, le Dysprosium offre la possibilité de créer un fort couplage entre le spin atomique et des champs lumineux, tout en gardant un taux de chauffage faible par rapport au cas usuel des atomes alcalins. Ceci ouvre la voie vers l’implémentation de champs de jauge artificiels, qui suscitent un vif intérêt dans le domaine des atomes froids dans un contexte de simulation quantique. Ce travail de thèse consiste en l’étude des mécanismes d’interactions dans un gaz de Dysprosium ultrafroid, allant des collisions assistées par la lumière à la relaxation dipolaire en passant par le refroidissement par évaporation. J’expose également la réalisation expérimentale d’un champ magnétique effectif en utilisant un déplacement lumineux dépendant du spin, permettant de contrôler optiquement la force des interactions atomiques au moyen d’une résonance de Feshbach.

In this thesis, I present the study of the laser trapping and cooling of a Dysprosium atomic gas. This latter belong to the lanthanide family, it exhibits a large angular momentum in its electronic ground state, making it a suitable candidate for investigating dipolar quantum gases. These systems present a major interest as they can lead to the observation of novel quantum phenomena thanks to the anisotropic and long-range character of the interaction between magnetic dipoles. Moreover, Dysprosium has a rich electronic structure offering the possibility to implement strong light-spin coupling with a reduced heating with respect to alkali species, which paves the way toward the realization of synthetic gauge fields.In this work, I present the experimental investigation of different interaction mechanisms occurring in an ultracold gas of Dysprosium, ranging from light-assisted collisions to dipolar relaxation and evaporative cooling. I expose also the experimental realization of an effective magnetic field, using spin-dependent light-shift, allowing optical control over atomic interactions by means of Feshbach resonances.
