Повний текст джерелаWater is one of the most common compounds on earth and is essential for all biological activities. Water has, however, been a mystery for many years due to the large number of unusual chemical and physical properties, e.g. decreased volume during melting and maximum density at 4 °C. The origin of the anomalies behavior is the nature of the hydrogen bond. This thesis will presented an x-ray absorption spectroscopy (XAS) study to reveal the hydrogen bond structure in liquid water.
The x-ray absorption process is faster than a femtosecond and thereby reflects the molecular orbital structure in a frozen geometry locally around the probed water molecules. The results indicate that the electronic structure of liquid water is significantly different from that of the solid and gaseous forms. The molecular arrangement in the first coordination shell of liquid water is actually very similar as the two-hydrogen-bonded configurations at the surface of ice. This discovery suggests that most molecules in liquid water have two-hydrogen-bonded configurations with one donor and one acceptor hydrogen bond compared to the four-hydrogen-bonded tetrahedral structure in ice. This result is controversial since the general picture is that the structure of liquid water is very similar to the structure of ice. The results are, however, consistent with x-ray and neutron diffraction data but reveals serious discrepancies with structures based on current molecular dynamics simulations. The two-hydrogen-bond configuration in liquid water is rigid and heating from 25 °C to 90 °C introduce a minor change in the hydrogen-bonded configurations. Furthermore, XAS studies of water in aqueous solutions show that ion hydration does not affect the hydrogen bond configuration of the bulk. Only water molecules in the close vicinity to the ions show changes in the hydrogen bond formation. XAS data obtained with fluorescence yield are sensitive enough to resolved electronic structure of water molecules in the first hydration sphere and to distinguish between different protonated species. Hence, XAS is a useful tool to provide insight into the local electronic structure of a hydrogen-bonded liquid and it is applied for the first time on water revealing unique information of high importance.

Повний текст джерелаThis study examines whether ‘climate bonds’ are achieving the desired investment scale to tackle climate change and whether those bonds are being issued with features that are attractive to institutional investors. Several cases of climate bond issuances, especially by companies were analyzed. While investor’s interest in climate bonds exists, this market is still small and investors are not being offered with an attractive investment scale. As the results indicate, both credit enhancements and aggregation vehicles to enable scale investments are possible solutions to boost the climate bond market.

Повний текст джерелаThis thesis investigates photoinduced transient dynamics of small molecules in solution with the use of time-resolved wide angle x-ray scattering (TR-WAXS). The core of the thesis is the precise determination of transient structures with the use of various structural optimization schemes. Some of the TR-WAXS results are supplemented with transient absorption optical spectroscopy (TOAS) and time-resolved x-ray emission spectroscopy (TR-XES) measurements allowing for a more complete description of the systems.par The work includes four different projects which can be grouped into two classes according to the type of reaction appearing upon photoexcitation: dissociation and electron transfer. The first class includes the simple triatomic molecules mercury halides and triiodide where we study the recombination dynamics of the free photofragments. This part of the thesis demonstrates the possibility to gain new knowledge about the dynamics of these model systems such as new recombination channels and reaction intermediates appearing in less than 100 ps, the xray pulse length from the synchrotron, by the use of time-slicing technique. The second class of systems includes transition metal complexes that are highly relevant for light harvesting applications, [Fe(NHC)2]2+ and Ru=Co, where the spin and structural dynamics are investigated. These projects extend previous work to a family of more complex systems constituted of relatively low-Z atoms (first row transition metals) and bring new insights into the photochemistry of the compounds

Повний текст джерелаThis paper deals with how the financing in real estate companies has developed after the recentfinancial crisis, how the financial crisis specifically has affected the financing in real estatecompanies and to what extent real estate companies have started to use alternative ways to finance their operations. This subject is of high interest because the financial crisis has had a huge impact on the global economic climate, which also affects Swedish real estate companies andbanks. The paper combines a quantitative survey of the capital structure in all Swedish publicly listed realestate companies with a qualitative survey consisting of a number of interviews withrepresentatives from a number of real estate companies and banks. The quantitative survey shows that big changes have occurred in the financing of real estatecompanies. The use of alternative ways to finance them, such as preference shares, bonds, MTN and certificate programs have become much more common in real estate companies. A big reason to this is that banks in many cases have wanted to restrict their lending to real estate companies whilst the credit margins have increased due to, among other things, higher capitalrequirement rates for the banks. The fast development of financing in real estate companies will continue for years to come andalternative ways to finance real estate companies will continue to get stronger as a complement to bank loans and common stock equity.

Повний текст джерелаAstatine (At, Z = 85) is a scarce halogen element, all of its isotopes being radioactive. Due to the limited available quantities, no spectroscopic tool is applicable to identify the molecular nature of At species. Consequently, the chemistry of At remains poorly known. One of its isotopes, ²¹¹At, is a potential candidate for the treatment of cancers by targeted alpha therapy. However, the limited knowledge of its chemical properties has hindered attempts to label ²¹¹At with disease targeting carrier molecules. This led to the development of a research program on the basic chemistry of At. This thesis focuses more particularly on the Pourbaix diagram of astatine and the characterization of halogen bonds with the AtI species, by means of various experimental tools (ion chromatography, competition method and electromobility). In the first part, speciation studies of At in alkaline medium confirm the presence of the At⁻ species under reducing conditions. As the potential increases, the AtO(OH)₂⁻ species is formed. The speciation change between these two species is described for the first time. In a second part, the formation of halogen bonds between the AtI species and various organic compounds was studied. The reactivity is summarized by a newly established basicity scale, with the strength between the donor (AtI) and the acceptor atom following the order of C≤ O ≤ S (≈ Se)

Повний текст джерелаThe relative disposition of applicative molecular systems by an advanced organization method is a well-defined strategy (core-shell type crystals). It is aimed at developing innovative materials.The presented study deals with the elaboration of a new organization method concerning the crystalline matter to obtain “network of crystals”. This strategy of materials processing occurs at a macroscopic scale and in a hierarchical way.Firstly, series of isostructural crystalline molecular networks have been designed with a molecular tectonics approach. These series, formed by hydrogen bonds, are then used for the study of the epitaxial growth of crystal. The preparation of a single crystalline architecture with a defined sequenced area of different compositions is demonstrated: core-shell crystals and welded crystals.Finally, the developed strategy is applied to coordination networks exhibiting luminescent properties in order to generalize the described process

Повний текст джерелаThe structure of DNA molecule and the interactions with its surrounding water is a hot topic for long time. In this thesis, we employ the nonlinear spectroscopy, including femtosecond pump-probe and two-dimensional infrared (2D IR) experiment, to study the vibrational dynamics of the systems. Double-stranded DNA short oligomers containing 23 alternating adenine-thymine base pairs were studied at different hydration levels by femtosecond 2D IR spectroscopy. For a DNA film at 0% relative humidity, the transient spectra enable a separation of the NH stretching mode of thymine from the symmetric and asymmetric NH2 stretching modes of adenine and determine the individual line shapes. For the NH stretch of thymine, the spectra demonstrate an essential homogeneous broadening, whereas for the symmetric and asymmetric NH2 stretches a pronounced and time-independent inhomogeneous broadening suggests a disorder in DNA structure. An energy transfer from the asymmetric NH2 stretch of adenine to the NH stretch of thymine is also observed. When the relative humidity increases, the increased water molecules have limited influence on the positions and line shapes of NH stretching frequencies, suggesting the spectral dynamics governed by DNA rather than water fluctuations. In contrast, the OH stretching mode of water shell around hydrated DNA undergoes a spectral diffusion on a 500 fs time scale, which is slower than the neat water. The guanosine-cytidine (GC) base pairs in chloroform solution were investigated to understand the interactions within base pairs. A local mode representationof NH stretching mode is adopted, consisting two free NH groups of G and C and three hydrogen bonded NH groups. The coupling and relaxation dynamics of the NH stretching excitations are studied by femtosecond pump-probe and 2D IR experiments. The results demonstrate a lifetime shortening upon the formation of hydrogen bonds, and an energy transfer between two hydrogen-bonded NH stretches.

Повний текст джерелаDie Gasphasenthermolyse ist eine lang bekannte und etablierte Methodik zur Synthese reaktiver Spezies. Sie ist allerdings auf flüchtige Substanzen mit einer guten Verdampfbarkeit beschränkt. Für schwerflüchtige Verbindungen, welche sich selbst im Hochvakuum nur mäßig oder gar nicht in die Gasphase bringen lassen, wurde in der vorliegenden Arbeit die Solution-Spray-Technik für die Anwendung im präparativen Maßstab entwickelt. Unter Verwendung von Ölzerstäuberdüsen, wie sie in der Heizungs- und Brennertechnik Anwendung finden, wurde die Erzeugung eines stabilen Lösungs-Sprays in die vorhandene Blitzvakuumpyrolyse-Technik integriert. Der Einfluss verschiedener Variablen, wie Flussrate, Druck, Temperatur und Lösungsmittel wurde untersucht. Die Solution-Spray-Technik wurde für die [3,3]-sigmatrope Umlagerung bestimmter Propargylthiocyanate zu Allenyl-isothiocyanaten angewendet. Des Weiteren wurde Propa-1,2-dienylisothiocyanat – das einfachste Allenylisothiocyanat – mit diversen sterisch anspruchsvollen primären und sekundären Aminen in mäßigen bis exzellenten Ausbeuten zu 2-Amino-1,3-thiazolen umgesetzt. Darauf aufbauend konnte eine Vier-Zentren-drei-Komponenten-Reaktion entwickelt werden. Es entstehen in hohen Ausbeuten 2-Amino-1,3-thiazole mit komplexen Substituenten an der 5-Position des Heterocyclus. Reaktionsmechanismen werden diskutiert um die alternative Bildung einer hochsubstituierten 1,3-Thiazinstruktur zu erklären. Der Einfluss von Reaktionstemperatur, Konzentration und Lösungsmittel auf das Produktverhältnis wurde ebenfalls untersucht und wird diskutiert. Es konnte gezeigt werden, dass 2-Amino-5-methyl-1,3-thiazole als offenbar erste aromatische Substanzklasse sehr gute Substrate für die Bildung von 1,3-Dioxanen nach Prins darstellen

Повний текст джерелаThe vitrification solutions used in the cryopreservation of biological samples aim to minimize the deleterious formation of ice by dehydrating cells and promoting the formation of the glassy state of water. They contain a mixture of different cryoprotective agents (CPAs) in water, typically polyhydroxylated alcohols and/or dimethyl sulfoxide (DMSO), which can damage cell membranes. Molecular dynamics simulations have been used to investigate the behavior of pure DPPC, pure DOPC, and mixed DOPC-β-sitosterol bilayers solvated in a vitrification solution containing glycerol, ethylene glycol, and DMSO at concentrations that approximate the widely used plant vitrification solution 2. As in the case of solutions containing a single CPA, the vitrification solution causes the bilayer to thin and become disordered, and pores form in the case of some bilayers. Importantly, the degree of thinning is, however, substantially reduced compared to solutions of DMSO containing the same total CPA concentration. The reduction in the damage done to the bilayers is a result of the ability of the polyhydroxylated species (especially glycerol) to form hydrogen bonds to the lipid and sterol molecules of the bilayer. A decrease in the amount of DMSO in the vitrification solution with a corresponding increase in the amount of glycerol or ethylene glycol diminishes further its damaging effect due to increased hydrogen bonding of the polyol species to the bilayer headgroups. These findings rationalize, to our knowledge for the first time, the synergistic effects of combining different CPAs, and form the basis for the optimization of vitrification solutions.

The purpose of public govermance is to provide the best welfare for the public by making use of limited resources. The purpose of government audit is to improve the impartial politics, assist the government to cleanse out political corruption, efficiently promote the government efficiency and improve welfare for the public. Audit Law was revised in 1998 last time and this version has been used for over 10 years without alteration. Whether the execution of relevant audit service meets the requirements of administration and control by current government is worth discussion. In addition, the government supervision can be divided into three parts including administration (higher authority), internal audit and audit institution, but is there functions overlapped and repeated that lower or affect the government efficiency? According to the Article 2 of Audit Law, the decision or behavior of audit institution will directly or indirectly affect the administration and policy of government. With the example of violating the recovering bid bond by Government Procurement Law, it is because when the audit institution uses the law and regulation retrieving system of Judicial Yuan to research for the cases which were related to the procurement bid bond of government recovering or confiscating, it informs the administrative agency to manage properly according to law. However, the property to audit and inform, force of law, influence on institutions and the legal nature recovering or confiscating follow-up bid bond lack of clear and specific treatment guidelines and stipulations. That made the administrative agency has ambiguity when it dealt with follow-up matters. This study focuses on discussing the nature and effect of auditing and informing laws of audit institutions, the audit system and the problem of alternate application of administrative laws and regulations. It further discusses the doubt about the audit institution informs the administrative agency to deal with the case of government procurement bid bond from the property of government procurement, hoping to provide proper advice of audit system and government procurement, improve the administrative efficiency of government and decrease the dispute of follow-up execution of administrative agency by the auditing and informing of audit institution.

Most of today’s materials require additional processing or modification steps in order to obtain the properties that make them suitable for a particular application. As an alternative to these traditional fabrication pathways, routes that use the self-assembly of polymeric building blocks are attracting increasing attention. We have synthesized poly(methyl methacrylate-b-4-vinylpyridine) (PMMA- b-P4VP) and poly(styrene-r-vinylphenol) (PS-r-PVPh) copolymers by using the anionic polymerization and the free radical polymerization, respectively. Well defined micelles through hydrogen bond have been prepared by mixing PMMA-b-P4VP diblock copolymer and PS-r-PVPh random copolymer in single solvent. The block copolymers were mixed with random copolymers, with the various B/R ratio (4/1, 2/1, 1/1, and 1/4) in which “B” and “R” represents block copolymers and random copolymers, respectively. The presence distribution of PVPh/P4VP and PVPh/PMMA hydrogen bonding depends on the feeding ratio of PVPh to P4VP. When the PVPh content lower than P4VP, hydrogen bonding occurs only between PVPh and P4VP; with excess PVPh, additional hydrogen bonding between PVPh and PMMA could occur. Furthermore, the effect of the solvent quality on the self-assembly behavior of PMMA-b-P4VP/PS-r-PVPh blends is investigated by considering THF and DMF as common solvent.

A series of poly(vinylphenol-b-styrene) (PVPh-b-PS) and poly(4-vinyl pyridine-b-methyl methacrylate) (P4VP-b-PMMA) block copolymers were prepared by anionic polymerizations of 4-tert-butoxystyrene、styrene、4-vinyl pyridine and methyl methacrylate , followed by selective removal of the 4-tert-butoxystyrene protective group by hydrolysis reaction . The dibolck copolymers were investigated by proton nuclear magnetic resonance spectrometry (1H-NMR), Fourier transfer infrared spectrophotometer (FTIR) , gel permeation chromatography (GPC) . Finally, studied by dynamic light scattering (DLS) and transmission electron microscopy (TEM) is the coaggregation of PVPh-b-PS and P4VP -b-PMMA in tetrahydrofuran (THF) and N,N-Dimethylformamide (DMF). Self-assembly of the associating diblocks by the hydrogen bonding resulted in interesting block copolymer aggregation behavior and morphologies in single solvent . Infrared spectra provide positive evidence of hydrogen bonding interaction .
