Abstract:
Syntheses of neutral 'buS2'-, 'S4'- and 'buS4'- and of anionic .buS2-complexes with various main group and transition metals are described. The complexes were prepared by reacting the neutral sulfur ligands or their alkali salts with the metal halide or alkoxide. The ligands coordinate to metal ions in normal as well as high oxidation states. No redox reactions occur in the latter case. The complexes are usually soluble in organic solvents and were characterized by elemental analysis and spectroscopic means.

Transition metal Schiff base complexes covalently immobilized on the surface of amino functionalized graphene sheet to catalyze C-C coupling reaction is reported. Graphene sheet which synthesized using mechanical exfoliation and then by differential oxidative reduction phenomenon of graphite. The schiff base ligand is prepared using aldehyde and amino groups containing compounds which further treated with metal salts to form metal complexes. The as-synthesized metal complexes was then incorporated into amino functionalized nanosheets which are characterized using different spectrochemical techniques. The catalytic investigation of the as-prepared catalyst were done by the cross coupling of aryl halides and aryl boronic acids to form biaryls as product in C-C cross coupling reaction. The yield of the products were high and selective which were analyzed using Gas chromatography technique. The advantage of this catalyst is high stability, recyclability easy recovery of catalyst, environmentally benign and mild reaction condition.

Abstract:
Transition metal catalysis has traditionally relied on organometallic complexes that can cycle through a series of ground-state oxidation levels to achieve a series of discrete yet fundamental fragment-coupling steps. The viability of excited-state organometallic catalysis via direct photoexcitation has been demonstrated. Although the utility of triplet sensitization by energy transfer has long been known as a powerful activation mode in organic photochemistry, it is surprising to recognize that photosensitization mechanisms to access excited-state organometallic catalysts have lagged far behind. Here, we demonstrate excited-state organometallic catalysis via such an activation pathway: Energy transfer from an iridium sensitizer produces an excited-state nickel complex that couples aryl halides with carboxylic acids. Detailed mechanistic studies confirm the role of photosensitization via energy transfer.

Abstract:
The work within this thesis has concentrated on the formation and isolation of titanium, vanadium, palladium, and mercury halides, with emphasis on the fluorides.TiF, TiF2, TiF3, and TiF4 have all been isolated within an argon matrix and infrared spectra obtained. From the titanium isotope splitting pattern a bond angle has been determined for TiF2 for the first time of 165o, or effectively linear. This work is also the first time that TiF has been isolated within an argon matrix. Work has also been conducted with vanadium which has lead to the isolation of VF5, VF4, VF3, and VF2, with VF4 undergoing Fermi Resonance. This is the first time that VF4 and VF2, consistent with a linear structure, have been isolated within a matrix.Work conducted upon palladium led to the isolation of numerous palladium fluorides, identified by the palladium isotope patterns in their IR spectra. Due to the similarity of the calculated stretching frequencies of PdF2, PdF3, PdF4, and PdF6 the assignment was challenging and so identification of these bands was conducted based photolysis and annealing behaviour in conjunction with computational calculations. This has allowed for the assignment of the bands present to PdF6, PdF4, PdF3, PdF2, and PdF.The bond length of molecular HgF2 has also been determined for the first time at 1.94(2) Å using the Hg L3-edge with EXAFS. Although the initial aim of this work was to isolate HgF4, using IR, UV/Vis, and XANES, no evidence could be found for oxidation states of mercury higher that HgII. The work also developed a new clean way of making HgF2 in a matrix. The identification of a new Hg…X2 complex was also discovered which when photolysed forms the HgX2 compound, this has only been proven for HgF2. This was achieved by isolating mercury atoms in an argon matrix doped matrices, photolysis of this matrix the led to the formation of HgF2 in significant amounts.

Abstract:
Abstract A free falling experiment was conducted as a simulation of a thermal spray process. A flattening behavior of the freely fallen metal droplet impinged onto a flat substrate surface was fundamentally investigated. The substrates were kept at various designated temperatures, and the substrates coated with gold by PVD were also prepared in order to investigate the effect of a wetting at the splat/substrate interface on the flattening behavior of the droplet. A falling atmosphere was atmospheric pressure nitrogen to prevent the oxidation of the melted droplet, and the experiments under low-pressure condition were also conducted. A transition of the splat morphology was recognized in atmospheric pressure nitrogen experiments, that is, the splat morphology on a room temperature substrate was a splash type, whereas that on a high temperature substrate was a disk type. The cross-section microstructure of the splat obtained on the room temperature substrate was an isotropic coarse grain, whereas that on the high temperature substrate was a fine columnar. The grain size changed transitionally with increasing the substrate temperature. Transition temperature on the gold-coated substrate was higher than that on the substrate without coating. The cross-section microstructure of the splat obtained under low-pressure was a fine columnar even on the room temperature substrate. The results indicate that the metal droplet wets better under low-pressure condition than in atmospheric pressure nitrogen condition, and the wetting has a significant role in the flattening of the droplet.

Abstract:
Abstract For continuous operation of Concentrated Solar Power (CSP) Plants it is necessary to integrate thermal energy storage module. High-density energy storage system at a high temperature is required for the new generation of large scale CSP plants. The Thermochemical Energy Storage (TCES) systems use the enthalpy of formation of a reversible chemical reaction for energy storage and release. Gas/solid reduction-oxidation (redox) reactions of solid metal oxides using air as heat transfer fluid (HTF) can be directly integrated with air operated CSP plants, and there is no need for HTF storage and any intermediate heat exchanger. A new generation of large scale CSP plants uses high-temperature solar collectors to increase power cycle efficiency. Such operating conditions require the development of suitable high-temperature TCES systems. The selection of suitable metal oxide reactant is very critical in the design of such high-temperature storage systems and requires a detailed study of the physics of reaction within the reactor. Cobalt oxide (Co3O4/CoO) has been verified to have a high reaction temperature, high enthalpy of reaction together with reasonable cyclic and thermal stability. Unique features of cobalt oxide require more fundamental study of the physics behind the redox reaction and its cyclic performance. Study of the physics of materials during the storage/release cycle is necessary for the design and improvement of the reactor and can be used as a benchmark for comparison of any implemented changes. A high precision, true differential TGA/DSC instrument is used for simultaneous measurement of weightchange (TGA) and true differential heat flow (DSC) for pure cobalt oxide (Co3O4) powder. Storage cycle (charge/discharge) was conducted for five cycles. Complete re-oxidation was achieved within reasonable times by performing the two reactions at close temperatures and controlling heating/cooling rates. Basic performance parameters were derived as a benchmark for future references. Single-cycle controlling parameters such as heating/cooling rate, dwelling time, and purge gas rate were investigated. System response for few initial cycles was studied. It was shown that pure cobalt oxide could regain weight and complete re-oxidation with reasonable stability. A transition for heat flow was detected after a few initial cycles which reduced discharge heat and decreased overall performance.

This paper presents an overview of a development project involving industrial cogeneration technology using 8,000-kW class hybrid gas turbines in which both metal and ceramics are used in parts subject to high temperatures in order to achieve high efficiency and low pollution. The development of hybrid gas turbines focuses mainly on the earlier commercialization of the turbine system. Stationary parts such as combustor liners, transition ducts, and first-stage turbine nozzles (stationary blades) are expected to be fabricated from ceramics. The project aims at developing material for these ceramic parts that will have a superior resistance to heat and oxidation. The project also aims at designing and prototyping a hybrid gas turbine system to analyze the operation in order to improve the performance. Furthermore, the prototyped hybrid gas turbine system will be tested for long-term operation (4,000 hours) to verify that the system can withstand commercialization. Studies will be conducted to ensure that the system’s soundness and reliability are sufficient for industrial cogeneration applications.
