Mezinárodní insolvenční právo / International insolvency law

Smržová, Martina January 2012 (has links)
Martina Smržová, 2011/2012 Abstract International Insolvency Law Key Words: COMI, Establishment, Vis Attractiva Concursus With regard to the broad extent of international insolvency law, the author focuses mainly on the Court's jurisdiction in the context of the European insolvency law. The subject of interest is therefore the EC Regulation No. 1346/2000 on insolvency proceedings (the "insolvency regulation"). The aim of this thesis is (1) to summarise development of interpretation of the most important terms concerning the court's jurisdiction to open the main insolvency proceedings, the secondary proceedings and proceedings which relate to the insolvency proceedings; and (2) to propose amendments to the insolvency regulation especially regarding the Report which will be prepared by the Commission on application of the insolvency regulation no later than the 1 June 2012. The work is divided into five main chapters. A short introduction in the first chapter is followed by the second chapter which deals with an introduction on the international insolvency law. The theories and the most important legal instruments on this area of law are introduced. The third and key chapter deals with the European insolvency law; it consists of eight subchapters. In the first subchapter the development and principles of...

Part I: The Synthesis and Characterization of Scorpionate Ligands for Lanthanide Complexation for Potential PARACEST Applications. Part II: The Synthesis and the Characterization of New and Old Organic Dyes

Nicholls-Allison, Emma 21 April 2015 (has links)
Reported in Chapter 2 of this thesis is the reliable and tolerant synthesis of a small library of pyrazole and triazole heterocycles. This synthesis was achieved in two steps in good yields from the reaction of acetophenone and benzamide derivatives with dimethyl formamide-dimethyl acetal followed by a cyclization with hydrazine. Also reported is the synthesis and characterization of their corresponding scorpionate ligands. Preliminary co ordination chemistry was done with a variety of lanthanide metals and was studied by standard spectroscopic methods as well as variable temperature 1H NMR, which revealed that Curie-Weiss behaviour was followed for these complexes in solution. An X-ray crystal structure of a nine co-ordinate ytterbium metal centre with eight nitrogen atom (four pyrazole, four pyridine) donors and one chloride atom was obtained, which may have been a product of decomposition during crystal growth. The bond lengths of this structure were compared with other lanthanide complexes of similar structural motifs. This comparison supported the theory of decomposition as the pyridine nitrogen atom-ytterbium bond lengths were longer than the average ytterbium-nitrogen atom bond length. Reported in Chapter 4 of this thesis is the synthesis and partial characterization of a new organic dye named perinaphthindigo. Perinaphthindigo was synthesized with adapted iv Baeyer-Drewson reaction conditions for the synthesis of indigo which involved the treatment of 1,8-nitronaphthaldehyde with acetone under basic conditions, and was found to be an intense green colour in solution. Perinaphthindigo was produced in poor yields, so efforts were undertaken to improve the yields through an alternative two-step synthesis, first between 1,8-nitronaphthaldehyde and nitromethane in a Henry reaction followed by oxidative coupling. The synthesis of perinaphindigo was adapted so as to structurally modify the final compound, either through incorporation of solubilizing tert-butyl groups or bromine atoms for future cross-coupling chemistry. The brominated derivatives of perinaphthindigo were also synthesized in low yields so cross-coupling conditions were scanned on model precursor compounds. The brominated perinaphthindigo compounds were found to have a bathochromically shifted absorbance maximum from the parent perinaphthindigo. This bathochromic shift was more pronounced in our compounds than in the comparison of indigo and 6.6’-dibromoindigo which indicates our compounds are more sensitive to perturbation by substitution. Reported in Chapter 5 of this thesis is the study of the acid and base chemistry of Nindigo, a previously reported compound. The treatment of Nindigo with a series of strong acids led to an interesting “protoisomerization”, or trans to cis isomerization of the central olefin, with ultimate structural determination through X-ray crystallographic methods. This isomerization was studied through absorbance stopped-flow methods which identified a probable pathway of the isomerization through a neutral, cis species. The investigation of neutral Nindigo was undertaken to attempt to identify two peaks which are red-shifted from the π-to-π transition at 586 nm. These two peaks appear at 657 nm and 741 nm and are present in all solvents. The preparative acid chemistry allowed us to assign the first red shifted peak at 657 nm to the cationic species. Aggregation studies showed concentration dependent behaviour of the ratio between the peaks at 586 nm and 657 nm with little effect on the species at 741 nm. In order to probe whether an autoionization process was occurring, variable temperature NMR and UV-Vis experiments were performed which did not provide a definitive answer to the species at 741 nm. / Graduate

Nanomaterials Self-Assembly Driven by Beta-Amyloid Peptides

Tanase, Maria Elena 20 May 2005 (has links)
Nanomaterials such as gold nanowires and gold nanoparticles were self-assembled with several peptides derived from betaamyloid peptide. The peptides propensity to form fibrilar structures was exploited. The products obtained by aggregation of the peptides with the nano materials were studied using HPLC, UV-vis spectroscopy, TEM and optical light microscopy.

The voltammetric results suggest that CuNi is electroplated, forming a solid solution. By cyclic voltammetry, the influence of different electrolytic bath in the electroplating of CuNi was investigated, where if it observed the formation of more noble alloys in sulphate baths and tartarate and less noble alloys in citrate and citrate/tartarate medium. Hydrodynamic experiments had been carried through, where it was verified for CuNi in sulphate and tartarate a transport of diffusional mass; for CuNi in citrate and citrate/tartarate was not observed the formation of diffusional plateau, suggesting a transport of mass by charge transference. By dispersive energy of rays-X, the atomic percentage of the constituent of the alloy was determined, where CuNi alloy in sulphate bath and tartarate present a percentage of nickel about 20% and in citrate and citrate/tartarate medium, the percentage of nickel falls espectively for 2% and 4%. By spectrometry of absorption of UV-Vis it was calculated the _ values for individual metals and CuNi, being found low values, indicating that as much the individual metals as the alloy in the different electrolytic transitions d-d type. It was made a comparative study between the electrochemical techniques (Linear Sweep Voltammetry, Chronoamperometry) and Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES), for copper determination. The copper taxes determined for both methods are near, presenting small variations, where the gotten errors are distributed in a random way presenting an average value of 2,56%. The carried through statistical tests had shown that the gotten results are in a reliable band of 95%. Based in these results it is possible to affirm that the used electrochemical techniques are efficient in the copper determination, making possible, thus, the validation of these for ICP-OES. / O interesse pela eletrodeposição de CuNi e suas múltiplas camadas é principalmente devido às propriedades destes materiais, tais como: resistência à corrosão, propriedades mecânicas (alta força de tração, maleabilidade e ductilidade) e magnéticas, além de suas propriedades catalíticas. Os resultados voltamétricos deste trabalho sugerem que a liga de CuNi é eletrodepositada formando uma solução sólida. Por voltametria cíclica, foi investigada a influência de diferentes banhos complexantes na eletrodeposição de CuNi, onde se observou a formação de ligas mais nobres em banhos de sulfato e tartarato e ligas menos nobres em meio de citrato e citrato/tartarato. Foram realizados experimentos hidrodinâmicos, onde severificou que CuNi em meio de sulfato e tartarato apresentam transporte de massa difusional. Para CuNi em meio de citrato e citrato/tartarato, não foi observado a formação de patamares difusionais, onde se sugere um transporte de massa por transferência de carga ou misto. Pelos resultados obtidos observou-se que o meio complexante influência na nobreza e no tipo de transporte de massa da liga formada. Por Energia Dispersiva de Raios-X, foi determinado o percentual atômico dos constituintes da liga, onde as ligas CuNi em banho de sulfato e tartarato apresentam um percentual de níquel em tono de 20% e em meio de citrato e citrato/tartarato, o percentual de níquel cai para 2% e 4%, respectivamente. Por espectrometria na região de absorção do UV-Vis, foram feitos curvas de calibração e calculado _ para os metais individuais e para CuNi, sendo encontrado baixos valores, indicando que tanto os metais individuais como a liga nos diferentes meios complexantes apresentam transições do tipo d-d. Foi feito um estudo comparativo entre as técnicas eletroquímicas (VLDA, Cronoamperometria) e ICP-OES para determinação de cobre. Os teores de cobre determinados para ambos os métodos encontram-se bem próximos, mostrando pequenas variações, onde os erros obtidos estão distribuídos aleatoriamente, apresentando um valor médio de 2,56%. Os testes estatísticos realizados mostraram que os resultados obtidos estão numa faixa de confiança de 95%. Baseado nestes resultados é possível afirmar que as técnicas eletroquímicas utilizadas são eficientes na determinação de cobre, possibilitando, assim, a validação destas por ICP-OES.
