Повний текст джерелаIn this thesis, the formation of self-assembled monolayers of different chalcogenide molecules and planer π-conjugated molecules and their electronic and structural characteristics were systematically studied mainly by synchrotron based X-ray photoelectron spectroscopy, scanning tunneling microscopy and low energy electron diffraction. A study of formation of hybrid organic-inorganic self assembled structure was performed by layer by layer assembly of a dithiol on ZnO(0001) with intermediate metal deposition. Additionally as a complement to the study of chalcogen head group molecules the adsorption characteristics of selenium and sulfur were investigated. The high resolution XPS and near edge absorption fine structure spectroscopy allowed to investigate the characteristics of self-assembled monolayers of benzene selenide and selenophene on Cu (100), and dihexyldiselenide on Ni(111) and Pd(111) and showed in particular the existence of Se-C bond breaking processes and existence of different adsorption sites of molecules. These conclusions were supported by the study of atomic selenium adsorption, which also shows existence different adsorption sites for the atomic Se with different chemical environments. These conclusions are mainly based on high resolution XPS study of characteristic Se3d, Se3p spectra, valance band spectrum and LEED imaging. The formation of a 5,5- bis (mercaptomethyl)-2,20- bipyridine (BPD) with SH termination on ZnO(0001) was demonstrated allowing subsequent grafting of Ag and Ni and further assembly of BPD on this metal-dithiol layer. The changes in electronic properties were determined from valence band spectra. The large π-conjugated molecule, NTCDA, was deposited on different metal surfaces and its structure morphology and chemical properties with respect to the metal surface was investigated. The NTCDA molecules displays a lying down structure with two different domains on Ag (110) and Cu(100) but three domain on Cu(111) surface. Compared with the one on the inert Au surface, a strong interface interaction between the molecules and Cu, Ag substrates plays an important role in determining the orientation and bonding state of the organic films

Повний текст джерелаAtomic sources, thermal protection for atmospheric re-entry and plasma-catalyst systems for air pollution control are just few examples of applications where interaction between N2/O2 containing plasmas and the surface plays a central role. Mechanisms of heterogeneous processes in plasmas are still barely understood. Unknown conditions on the surface limit the accuracy and predictive capability of the kinetic models. In the first part of this work we investigate adsorption and chemical reactions of O and N atoms on oxide surfaces (silica, Pyrex, TiO2) under plasma exposure. We use tuneable laser absorption spectroscopy, broad-band UV absorption spectroscopy, two-photon absorption laser-induced fluorescence (TALIF) and mass spectrometry to monitor interaction between gas phase species and the surface. Surface analysis is performed using x-ray photoelectron spectroscopy (XPS). It has been shown that stable Oads and Nads atoms are grafted to oxide surfaces under exposure to low pressure (~1 mbar) plasmas in O2 and N2. The coverage and reactivity of adsorbed atoms has been probed by exposing the pretreated surface to stable molecules (NO, C2H2) and radicals (O, N). Using isotopic exchange 15N↔14Nads and 18O↔16Oads under plasma exposure the role of chemisorbed species in surface catalysed recombination of atoms has been investigated. In the second part of this thesis, relaxation of vibrationally excited N2 molecules on catalytic surfaces is studied using infrared (IR) titration technique. Mixtures containing 0. 05 - 1% of CO2 (CO, N2O) in N2 at p=1. 3 mbar are excited by a single dc discharge pulse. The kinetics of vibrational relaxation of IR tracers during the post-discharge is followed using quantum cascade laser absorption spectroscopy. Due to a very efficient vibrational energy transfer between N2 and CO2 (CO, N2O), excitation of IR tracers is an image of the vibrational excitation of N2. Relaxation measurements have been interpreted in terms of a numerical model of non-equilibrium vibrational kinetics. Probability of N2 vibrational quantum loss has been determined from the best agreement between the experiment and the model

General Abstract Lymphoma, a cancer of the white blood cells in the body, is one of the most common malignancies in dogs. Although treatment with a multi-agent chemotherapy protocol results in high remission rates, the remission duration is usually less than one year, with the majority of patients relapsing. In an effort to improve remission rates and survival times, scientists have been working to develop therapeutic interventions that target specific points in the development and replication cycle of a cancer cell. One such strategy, targeting checkpoint molecules programed death (PD)-1 and PD-L1, has shown promise for several different types of human cancers, including lymphoma. PD-1 is a receptor on T cells, which together with its ligands, PD-L1 and PD-L2, decreases lymphocyte function when activated. This is a protective mechanism, acting to inhibit sustained harmful inflammation in a normal healthy dog. Some cancers have taken advantage of this pathway, increasing expression of PD-L1 or L-L2 in order to evade detection by the immune system. To date, little is known regarding the role and expression of these immune checkpoint molecules in dogs with lymphoma. We sought to evaluate if PD-1, PD-L1 and PD-L2 expression is significantly increased in canine lymphoma compared to reactive lymphoid hyperplasia controls. Tissue samples were collected from two sources. Cytology samples of lymphoma and reactive lymphoid hyperplasia were collected by fine needle aspiration from clinical patients. Formalin fixed paraffin embedded tissue samples of lymphoma and reactive lymphoid hyperplasia were collected from the archived tissue bank. Using a molecular analysis technique called quantitative reverse transcription PCR (qRT-PCR) we measured the amount of messenger RNA (mRNA) encoding PD-1 and its ligands PD-L1 and PD-L2 in lymphoma and in reactive lymphoid hyperplasia controls. In our results we did not observe an upregulation in the expression of checkpoint molecules in canine lymphoma relative to canine reactive lymphoid hyperplasia. This suggests there may be a limited therapeutic application for PD-1 and PD-L1/PD-L2 blockade in canine lymphoma. Although these results do not suggest that checkpoint inhibitors would be useful for treatment, they give insight into the mechanisms of unchecked lymphocyte proliferation in canine lymphoma.

Повний текст джерелаSelective functionalization of unactivated C−H bonds and dioxygen reduction reaction (ORR) are extremely important in the context of addressing various technological issues such as energy-crisis, synthesis of commercially important organic compounds, etc. The utilization of molecular oxygen as an abundant and environmentally benign oxidant is of great interest in the design of bioinspired synthetic oxidation catalysts. The catalytic four-electron reduction of dioxygen to water has also merited increasing attention because of its relevance to fuel cell technology. Naturally occurring metalloenzymes activate dioxygen by employing cheap transition metals (e.g. iron, nickel, manganese, and copper) and exhibit diverse oxidative reactivities. Moreover, such reactions are carried out under ambient conditions with high efficiency and stereospecificity. Therefore, the isolation and characterization of the high-valent metal-dioxygen intermediates (such as metal-superoxo, -peroxo, -hydroperoxo, and -oxo can provide a lot of useful information about the reaction mechanisms and is therefore helpful for the future design of more efficient catalysts. This thesis has explored the chemistry of different metal-dioxygen intermediates ranging from bridging end-on μ-1,2-peroxo-dicobalt(III) species to nickel(II)-superoxo cores. Detailed spectroscopic and reactivity studies of the intermediates have been performed to reveal the correlations between their electronic structures and reactivity patterns. In my present thesis, I investigated the effect of the ‘structure-activity relationship’ of different metal-dioxygen intermediates towards exogenous substrates. This thesis also demonstrated the impact of suitable ligand design on the behaviour of a given metal-dioxygen reactive system.

Повний текст джерелаMicrocystins (MCs) are a family of heptapeptide toxins produced by some genera of Cyanobacteria. MCs have potent hepatotoxicity and tumor-promoting activity. Leukocyte infiltration in the liver was observed in MC-induced acute intoxication. Although the mechanisms of hepatotoxicity induced by MCs are still unclear, neutrophil infiltration in the liver may play an important role in triggering toxic injury and tumor development. The purpose of this thesis was to investigate the effects of three structurally distinct MCs (MC-LA, MC-YR and MC-LR) in the neutrophil functions: synthesis and expression of adhesion molecules, rolling, adhesion, migration and release of cytokines and ROS. In migration assays of the air pouch, the three MCs similarly induced the migration of leukocytes in vivo in subcutaneous tissue of rats and differentially the secretion of pro-inflammatory cytokines (CINC-2αβ, IL-1-β, TNF--α, VEGF- α and MIP-2) in exudates. Elevated concentrations of CINC-2αβ were found in the inflamed exudates from animals injected with MC-LA, MC-LR or MC-YR, although MIP-2 was only detected in the exudates from animals injected with MC-LR. There were no changes in the secretion of IL-1-β, TNF-α and VEGF--α. Intravital microscopic studies showed that topical application of MC-LR enhanced the numbers of rolling and adhered leukocytes in the endothelium of postcapillary mesenteric venules. The latter effects may be dependent upon induction of the synthesis and expression of L-selectin and -α2-integrin in neutrophils, as assessed by flow cytometry and RT-PCR, respectively. Conversely, the three toxins promoted direct locomotion of neutrophils and enhanced their migration in response to fMLP, as measured by Boyden chamber assays, and increased intracellular calcium, a messenger in the chemotaxic process. The effects of MC-LA, MC-YR and MC-LR in human neutrophils and mice had the same pattern of response. The analyses of cell viability, DNA fragmentation, mitochondrial membrane depolarization of and release of intracellular ROS were evaluated by the technique of FACS. Extracellular ROS content was measured by lucigenin-amplified chemiluminescence, and cytokines were determined by ELISA. We found that these MCs increased interleukin-8 (IL-8), cytokine-induced neutrophil chemoattractant-2αβ (CINC-2αβ) and extracellular ROS levels in human and rat neutrophils. In conclusion, our results showed that MCs act on specific pathways of neutrophil recruitment, indicating their potential effect on neutrophils activation. This process can significantly contribute to the pathogenesis of hepatic damage due to generation of ROS by neutrophils as well as act on hepatocytes under such conditions and potentially increase injury processes induced by MCs.

Повний текст джерелаMicrobial contamination on surfaces has become major concern in various areas including industrial process as well as public health and hospitalization. Being aware of several problems causing by adherence and attachment of bacteria on a surface, preparation of antibacterial surface has become a global research interest for researchers in many domains. From the chemistry integrated with material science and microbiology point of view, functionalization of existing polymeric material surfaces is an attractive solution. In this domain, the surface functionalized with covalently grafted antimicrobial polymers represents an ideal solution. In order to facilitate the screening process, it is proposed in this particular research a new approach to obtain polymers with antimicrobial properties both in solution and from surface. The present approach includes a study in controlled (co)polymerization of active ester(s) serving as intermediate templates that can be eventually modified by polymer post-modification process to fabricate polymer of interest with expected antimicrobial characteristics.In general, it is demonstrated herein that the use of Cu(0)-mediated reversible deactivation radical polymerization (RDRP) is a suitable technique that allows facile preparation of reactive (co)polymers in solution and from surface of poly(ethylene terephthalate). First of all, this thesis focused on the study of controlled polymerization of pentafluorophenyl methacrylate (PFPMA) which appeared to be challenging. Furthermore, along with the optimization of polymerization in solution was the investigation of surface-initiated polymerization of this monomer from PET surface. Besides, polymerization of p-nitrophenyl methacrylate (NPMA) and copolymerization of the two active esters by Cu(0)-mediated RDRP were also examined. In addition, polymer post-modification of obtained (co)polymers with various compounds had been proven to be efficient, easy to perform. The structure and characteristics of obtained products were confirmed to match with expectations. It is remarkable that the post-modification can be done as sequential process, single or dual functionalization with several different essential oils, which are natural antibacterial or antioxidant compounds. On the other hand, the success in polymerization and post-modification of polymer of active esters in solution allowed the fabrication of different PET film grafted with polymers that are envisaged to have antiadhesion properties. Attempts to test such properties were also done against two model bacteria including Staphylococcus aureus and Pseudomonas aeruginosa to investigate if expectations are valid

Повний текст джерелаIn this PhD we present the analysis of the reactive dynamics of triatomic systems of interest for the primordial chemistry. Simulations have been mainly done using the quasi-classical trajectory formalism (QCT approach) for which a code has been developed. iT has the advantage of being able to determine the state-to-state rate constants with a low numerical cost and a large temperature domain. We have shown that the QCT results are very reliable in the high collision energy domain by realizing a limited number of time dependent quantum method calculations (MCTDH method). A huge number of rate constants (~300000) has been determined for the systems H3, H2D, typical of direct processes. Our study also revealed the importance of dissociation for high temperature regime (T > 10^3 K). The new kinetic data will permit to constrain the molecular abundances of H2 and HD, hence giving reliable cooling functions for the dynamics study of collapse of the molecular clouds precursor of the first stars. Those data could be employed in interstellar medium in regions where high internal energy molecular states are relevantly populated (PDR or C-type shocks). We present the indirect reaction dynamics of the systems H2D+ and HeH2+. For those processes that can be characterized by a long lifetime intermediate complex, we have shown that a approximated quantu method (RPMD method) can be very efficient to determine thermalized rate constants and represents an interesting approach for many reactions in astrochemistry

Повний текст джерелаThe main focus of this thesis is the investigation of the dissociation dynamics of aryl halides using femtosecond pump-probe spectroscopy. In the monohalogenated aryl halides, iodo-, bromo- and chlorobenzene, the rate of dissociation following excitation at 266 nm in the gas phase increased with increasing mass of the halogen atom. This process was assigned to predissociation of the initially excited singlet (π, π*) state via a repulsive triplet (n, σ*) state due to spin-orbit interaction. In addition to the predissociative mechanism, a direct dissociation channel was observed in iodobenzene. The rate of the predissociation in bromobenzene was found to be faster in the condensed phase than in the gas phase, which can be explained by solvent-induced symmetry perturbations. Ab initio calculations of the potential energy surfaces of the ground state and several low lying excited states in bromobenzene have been performed in order to verify the suggested mechanism. Substituting one of the hydrogen atoms in bromobenzene affected the predissociation rate significantly. In o-, m- and p-dibromobenzene the predissociation rate increased with decreasing distance between the bromine atoms in accordance with an increased spin-orbit interaction introduced by the bromine substituent. The fastest predissociation rate was observed in 1,3,5-tribromobenzene. With chlorine and fluorine substitution, inductive and conjugative effects were found to be of importance. In the o- and m-isomers of the dihalogenated aryl halides, an additional faster dissociation channel was observed. Guided by ab initio calculations of the potential energy surfaces in the dibromobenzene isomers, we ascribed the fast dissociation pathway to predissociation of an initially excited triplet state. Upon methyl group substitution in bromobenzene, the decreased lifetime of the initially excited state was attributed to an incresaed density of coupled states.
Another system which has been studied in the condensed phase is diiodomethane. Using Car-Parrinello molecular dynamics simulations we observed a prompt dissociation and subsequent recombination to the isomer, iso-diiodomethane, in acetonitrile solution.
Vibrational wavepacket dynamics in the C (1Σ+) state of NaK were studied using a direct ionization probing scheme. A simple analytical expression for the pump-probe signal was developed in order to see what factors that govern direct ionization of the vibrational wavepacket. Our experimental data was consistent with a photoionization transition dipole moment that varies with internuclear distance.
