Abstract:
The recently proved one-to-one structural equivalence between a conjugated hydrocarbon CnHm and the corresponding borane BnHm+n is applied here to hybrid systems, where each C=C double bond in the hydrocarbon is consecutively substituted by planar B(H2)B moieties from diborane(6). Quantum chemical computations with the B3LYP/cc-pVTZ method show that the structural equivalences are maintained along the substitutions, even for non-planar systems. We use as benchmark aromatic and antiaromatic (poly)cyclic conjugated hydrocarbons: cyclobutadiene, benzene, cyclooctatetraene, pentalene, benzocyclobutadiene, naphthalene and azulene. The transformation of these conjugated hydrocarbons to the corresponding boranes is analyzed from the viewpoint of geometry and electronic structure.

Abstract:
By cyclic and differential thermal analysis were studied conditions that reduce melt overcooling in a number of aromatic hydrocarbons such as diphenyl, diphenylethane, diphenylmethane, diphenylbenzols, naphthalene, and their mixtures. Based on experimental outcomes some practical conclusions were made for effective application of that substances as heat-accumulating materials. First of all, the thermal cycle, including melting and crystallization, is reasonable to carry outwith soft heating near the melting point for specified hydrocarbons. Secondly, it was concluded from the phase diagram analysis of hydrocarbon mixtures, that more effective will be using of alloys of eutectic composition (without thermal cycling limitation).

Abstract:
Cyclic Aromatic molecules are the subject of continued research due to their highly advantageous characteristics which can be exploited in the areas of pharmaceuticals, material science and nano-electronics. While the defining properties and criteria for a molecule to be considered aromatic are very specific and well established, the degree of aromaticity of these molecules and their corresponding ordering remains a source of continued debate. Given that the macroscopic aromatic properties are fundamentally rooted in the underlying electronic structure and molecular dynamics, these properties can be probed in numerous ways. One such method is to exploit the strong laser field as it pertains to non-linear light-matter interaction. More specifically, the study of photoionization, as a direct resultant effect of strong field light-matter interaction, gives us direct insight into electronic and spatial properties as captured via mass spectroscopy. As a strong-field process, photoionization is effective because the variables that influence its results are also the ones that define aromaticity thus a correlation can be postulated. Other strong field advanced techniques to probe aromacity such as High Harmonic Generation (HHG) have already been successful shown by our group to be effective spectroscopic tools. In this way, photoionization provides supporting evidence to enhance the understanding of these novel spectroscopic tools. This thesis demonstrates that photoionization mass spectroscopy can be used as a probe into the aromaticity order of 5-membered cyclic aromatic molecules. Furthermore, the thesis will show that photoionization results correlate with the previously conducted HHG studies in this area thus further supporting these techniques as sensitive spectroscopic tools into aromaticity. The first part of this thesis describes the characterization of aromatic molecules and the corresponding process to obtain photoionization results that can be correlated to aromaticity. In the second part, these results are compared to the theoretical model and HHG demonstrating consistent results. The third and final component of this thesis describes future work, namely two-colour control of photoionization which is intended to provide greater resolution and variation of photoionization spectra thereby providing a more comprehensive and conclusive understanding of the proposed correlation with aromaticity.

Abstract:
Chapter one contains a brief summary of the cluster-surface analogy, with a structural comparison between metal clusters and the chemisorbed state. Particular emphasis is directed towards the adsorption sites adopted by benzene on the metal surface, and the analogous coordination modes found in cluster compounds. Chapter two describes the synthesis and characterisation of a number of benzene and cyclic C<SUB>6</SUB> alkene containing clusters based on an osmium tetrahedral framework, in which the chemistry is dominated by C-H bond activation reactions. Chapter three deals with the analogous ruthenium chemistry, in which a butterfly arrangement of the four metal atoms seems to predominate. An example of cluster mediated ring contraction and its relevance to surface chemistry is discussed, as is the synthesis of an octaruthenium benzene cluster. The molecular organization of arene cluster complexes in the solid-state is also presented. Chapter four introduces the [2.2]paracyclophane molecule as a new class of π-ligand in organometallic chemistry, and describes the synthesis of a number of ruthenium cluster derivatives, one of which is considered to be a key intermediate in the formation of carbido-atoms in such species. Unique metal polyhedra, and an unusual coordination mode for CO are described. Chapter five gives a detailed account of the reactivity of the triruthenium and hexaruthenium-carbido [2.2]paracyclophane clusters with ligands such as alkynes, phosphines and dienes. Products are discussed which serve as models for the chemisorption of benzene on the metal (111) surface. Chapter six presents the experimental details and spectroscopic and crystallographic data for all compounds synthesised throughout the work described in this thesis.

Abstract:
This thesis describes the photochemistry and ultraviolet (UV) spectroscopy of cyclic aromatic hydrocarbons such as benzene and naphthalene, along with small water clusters and crystalline water ice clusters. Firstly, benzene and naphthalene interactions with small water hexamer (W6) clusters, and then benzene interactions with crystalline water ice clusters are investigated. This thesis primarily focuses on the applications of a range of computational chemistry techniques to investigate and characterize excited states of these complex systems, which are generated following one-photon absorption. Benzene and naphthalene, as prototypical polycyclic aromatic hydrocarbons (PAHs), and water and crystalline ice clusters, taken as representative of interstellar ices, could also be considered as useful model systems to replicate polycyclic aromatic hydrocarbons (PAHs) in interstellar ices, and to study their behaviour under UV processing. From coupled cluster (CC) benchmark studies on small water clusters up to water the pentamer, it is shown that that highly correlated linear-response coupled cluster methods such as CCSD and CC3 are important to consider while studying electronic excitations, as electron correlation effects play an important role in such systems, with double excitations playing a dominant role. However, triple excitations contributions calculated are negligible with CCSD and CC3 methods converging monotonically to similar results. The aggregation effect on water at CCSD level has shown a blue shift of ~ 0.7 eV in the central water molecule of water pentamer (C2v) relative to water monomer (C2v), and is in good agreement with the experimental blue shift of ~ 1 eV in condensed phase. For both benzene- and naphthalene-bound water W6 clusters, we have calculated interesting features of benzene- and naphthalene-mediated electronic excitations of the water W6 cluster at wavelengths where photon absorption cross section of water is negligible i.e., above 170 nm. These excitations were originally absent in the isolated water W6 cluster. Similar features are calculated for benzene-bound crystalline ice clusters, which also illustrate the effect of cyclic aromatic hydrocarbons on electronic excitations of ice clusters, and are also observed experimentally. The brightest π → π* electronic transition of benzene and naphthalene is calculated to be red-shifted in wavelength and occurs with lower intensities after interacting with the water W6 and ice clusters. The degeneracy of this transition is also slightly broken in benzene. We have observed new electronic transition features such as charge transfer (CT), and locally diffuse Rydberg type excitation in these complexes. We have found a good performance of hybrid DFT functionals i.e. M06-2X and CAM-B3LYP in calculating vertical excitation energies of these complexes using time dependent density functional theory (TD-DFT). Further, diffusion studies of the deuterium (D) atom have shown the importance of surface morphology in generating different potential sites and hopping characteristics of the D atom on crystalline and amorphous ice surfaces. D2 formation is found to be efficient on the amorphous ice surface, with longer residence times of the D atom indicating a possibility of the deuterium atom getting trapped in such sites. There is then a further possibility of the diffusing D atom to recombine with the trapped D atom to form a D2 molecule. However, such D atom trapping is a rare possibility on crystalline surface, as hopping is fast and thus the recombination process is not efficient on crystalline ice surface.

Abstract:
Hydrocarbons, in particular polycyclic aromatic hydrocarbons (PAHs), have been long discussed to be carriers of interstellar infrared (IR) emission and ultraviolet (UV) absorption features. Yet, their origin in dense phases of the interstellar medium (ISM), such as molecular clouds, remains unclear. In this work, growth mechanisms based on ion-molecule reactions between cationic PAHs/hydrocarbons and methyne (CH) were investigated. The reaction type and the precursor were derived and selected from known chemical and physical properties of the ISM. These chemical reactions were characterised by calculating branching ratios (based on cross sections) and capture rate coefficients, minimum reaction paths, reaction enthalpies, thermal equilibrium constants, and microcanonic isomerisation and radiative deactivation rate coefficients. In order to cope with the variety of reaction parameters, a hierarchic workflow scheme was set up. First, the reaction potential energy surface was sampled by molecular dynamics simulations. Then, minimum energy paths of the most probable reaction channels were investigated. Finally, molecular and kinetic properties of stationary points were calculated. The quantum chemical level of theory was increased at each step from DFTB (tight-binding density-functional), to DFT, and finally to post-Hartree-Fock methods. Results on CH based hydrocarbon growth showed the transition from non-cyclic hydrocarbons to cyclic and aromatic structures and from cyclic to polycyclic aromatic hydrocarbons. Additionally, the reactive collisions between hydrocarbons and CH were found to produce sufficient energy for isomerisation and fragmentation processes even at ultra low temperatures. In all, the results indicate that methyne might be a proper precursor for the formation of large interstellar PAHs<br>Kohlenwasserstoffe, insbesondere polyzyklische Kohlenwasserstoffe (engl.

In dieser Arbeit wurden daher die Bildungsmechanismen, welche auf Ion-Molekül-Reaktionen zwischen kationischen PAHs und Kohlenwasserstoffen und dem Molekül CH beruhen, untersucht. Sowohl der Reaktionstyp als auch der Präkursor wurden anhand von bekannten physikalischen und chemischen Eigenschaften des ISM abgeleitet und ausgewählt.

Abstract:
We are developing a novel classical over-the barrier model for electron transfer from an in nitely thin conducting disc to a point charge projectile to model multiple electron capture in e.g. keV collisions of atomic ions with poly-cyclic aromatic hydrocarbons (PAHs). In its nal form, the present model will incorporate the polarization of the PAH molecules due to the active electron and the point charge projectile at a general angle of incidence. This will drastically improve the description of the potential barrier in comparisons with simpler versions of the model where the nite size and polarizability of the target molecule is neglected or treated in an averaged fashion. In this work we arrive at expressions for the electrostatic potential energy barrier experienced by the active electron in the two spatial orientations where the point charge projectile is located along the normal symmetry axis and in the tangent plane of the disc. Applied to coronene (C24H12) such barriers compare better with high level density functional theory (DFT) calculations than with the results from the simpler versions of the classical over-the-barrier models for atomic and spherical cluster targets. These results thus strongly supports the conducting disc approximation of PAHs. Finally we discuss the nal steps in the model development and possible extensions of the model to include less symmetric elliptical discs or spherical caps.

Abstract:
Alternative liquid fuels can contain hydrocarbons of different types and chain lengths and the fuel composition has an influence on combustion behavior. In this study, the influence of liquid single-component fuels on exhaust gas emissions of a gas turbine model combustor for swirl-stabilized spray flames was investigated under atmospheric pressure. The nozzle exhibited a dual-swirl geometry and a prefilming airblast atomizer. The spray was characterized by Phase Doppler Anemometry (PDA) and Mie scattering measurements and the flame CH* chemiluminescence was measured. Six single-component hydrocarbons were chosen: three linear alkanes (n-hexane, n-nonane, n-dodecane), one cyclic alkane (cyclohexane), one branched alkane (iso-octane) and one aromatic hydrocarbon (toluene). Kerosene Jet A-1 was used as a technical reference. Results show minor differences in CO emissions and significant differences in NOx emissions of the various fuels at comparable flow conditions and adiabatic flame temperatures. The measurements indicate a correlation between the nitric oxide emissions and the spray quality.

Abstract:
The article analyzes two types of kerosene surrogates: six-component SU1 and four-component SU2. The characteristics of the both differ from the accepted reference values no more than by 1%. It is revealed that multicomponent surrogates are necessary for reproducing the physicochemical properties of the real aviation kerosene. In addition, various classes of hydrocarbons such as alkanes, cyclic alkanes, and aromatic hydrocarbons should be included in order to meet these properties. Other parameters such as density, H/C ratio, and molar mass impose additional and important constraints on the development of surrogates. Several methods for combined reactor prediction of the concentrations of carcinogenic polycyclic aromatic hydrocarbons (PAHs) in aircraft kerosene combustion chambers have been proposed and investigated.

Abstract:
The use of Jojoba Methyl Ester as a pilot fuel was investigated for almost the first time as a way to improve the performance of dual fuel engine running on natural gas or LPG at part load. The dual fuel engine used was Ricardo E6 variable compression diesel engine and it used either compressed natural gas (CNG) or liquefied petroleum gas (LPG) as the main fuel and Jojoba Methyl Ester as a pilot fuel. Diesel fuel was used as a reference fuel for the dual fuel engine results. During the experimental tests, the following have been measured: engine efficiency in terms of specific fuel consumption, brake power output, combustion noise in terms of maximum pressure rise rate and maximum pressure, exhaust emissions in terms of carbon monoxide and hydrocarbons, knocking limits in terms of maximum torque at onset of knocking, and cyclic data of 100 engine cycle in terms of maximum pressure and its pressure rise rate. The tests examined the following engine parameters: gaseous fuel type, engine speed and load, pilot fuel injection timing, pilot fuel mass and compression ratio. Results showed that using the Jojoba fuel with its improved properties has improved the dual fuel engine performance, reduced the combustion noise, extended knocking limits and reduced the cyclic variability of the combustion.

Abstract:
Thermal efficiency and NOx emission comparisons are made between the homogeneous charge compression ignition (HCCI) and the conventional diesel cycles on a number of common-rail diesel engine platforms of high compression ratios with conventional diesel fuel and dimethyl ether as a surrogate fuel. The empirical studies have been conducted under independently controlled exhaust gas recirculation (EGR), intake boost, and exhaust backpressure. The energy relevance of the combustible substances such as carbon monoxide and hydrocarbon species in the engine exhaust has been evaluated quantitatively. However, the impact of the hydrocarbons produced during the HCCI cycles on the attainment of ultra low levels of NOx is less understood and it is unclear if the hydrocarbon species are a precursor to the ultra low NOx and also contribute in part to the NOx reduction. Therefore, the chemical impact of the hydrocarbon species on the NOx emission under low temperature combustion cycles has been examined with crank-angle resolved in-cylinder sampling techniques and fast-response emission analyzers. This paper intends to identify the major impacts of the hydrocarbons on the fuel efficiency and emissions of diesel HCCI cycles.

Abstract:
Fuel cells are a promising technology to deal with energy sustainability, especially for mobility purposes the Proton Exchange Membrane Fuel Cell and hydrogen produced from biomass could be coupled to overcome the amount of CO2 emissions. In order to improve fuel cells performances the search for new electrocatalysts has a great importance in this technology the challenge for a fuel cell catalyst that is less poisoned by CO is one of the most important field in low temperature fuel cell developments that use alcohol and hydrocarbons as primary fuels. In this work PtSm, PtTb, PtDy, PtU, PtRuMo and PtRuDy systems have been synthesized by the colloid method, investigated by the following techniques: X-rays fluorescence analysis (XFA), X-rays powder diffraction (XRD), X-rays photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), high resolution transmission electron microscopy (HRTEM), cyclic voltammetry (CV) and polarization curves (Exi). The results obtained in this work shows that PtRuMo is the best choice for direct methanol oxidation. For direct ethanol oxidation the higher activity was found in PtRuDy system. PtU system was investigated and showed an interesting behaviour in ethanol oxidation. After two cycles of H2/O2 and ethanol/O2 the catalyst was able to reach the initial figures on hydrogen/oxygen oxidation which means that no degradation of the catalyst was indentified.

Abstract:
Fuel dilution in oil is a known issue for gasoline direct injection (DI) engines especially in colder climates and for customers with short, lightly-loaded driving cycles. In this work, oil samples were generated using a cold oil fuel accumulation test. Gas chromatography (GC) was used to speciate the hydrocarbons accumulated in the oil and characterize their quantity, type, molecular weight distribution, and volatility. Further testing and analysis was done to characterize the fuel hydrocarbons that evaporate from oil during engine warm-up conditions. The results demonstrate how the wide range of gasoline hydrocarbon volatility leads to different behavior in the accumulation and subsequent evaporation phases. Lastly, a model was created to extend this analysis and estimate the evaporation of hydrocarbons from the oil.
