Abstract:

Thin film optical sensors in which a halide sensitive fluorophore is immobilised in a thin (~ 50 micron) polymer film have been developed and characterised. The sensor films use rhodamine, 6-methoxyquinoline or harmane dyes which have been functionalised and bound to a hydrophilic copolymer. The selection, synthesis, functionalisation, and polymer-binding of the dyes is described, as is the synthesis and physical characterisation of the polymer supports. Two hydrophilic copolymers have been synthesised and characterised and twenty novel halide sensitive compositions have been synthesised, or f

Plusieurs methodes de calibration ont ete comparees : des methodes lineaire univariees et multivariees et des reseaux neuronaux. Dans le cas ou les interferences sont faibles ou nulles, les methodes univariees sont suffisantes pour determiner les concentrations mais dans le cas de tres fortes interferences, il

Le mécanisme de radiolyse de l’eau est bien établi. Sous l’effet des rayonnements ionisants, les produits de la radiolyse de l’eau pure sont les radicaux et les produits moléculaires tels que les électrons solvatés, les atomes hydrogènes, les radicaux hydroxyles, le peroxyde d’hydrogène et les ions hydroniums. Lorsque les solutions concentrées sont irradiées, le résultat de la radiolyse change à cause de la fraction d’énergie absorbée par le soluté, cette fraction est négligeable dans le cas des solutions diluées. Les produits de la radiolyse du solvant peuvent réagir avec les molécules du sol

Abstract:

Microwave excitation of pulsed metal vapour lasers (copper halide and strontium-ion recombination lasers) is investigated. Two waveguide coupling structures were designed and built, one based on a ridge waveguide; and the other based on a rectangular waveguide with a tapered narrow wall which was designed to produce a uniform, travelling microwave field. These coupling structures were designed to produce a transverse electric field at high pressure, with high electron densities, using pulsed microwaves with peak powers of up to 2.5 MW, compatible with the necessary requirements for copper and

Ion traps are an incredibly versatile tool which have many applications throughout the physical sciences, including such diverse topics as mass spectrometry, precision frequency metrology, tests of fundamental physics, and quantum computing. In this thesis, experiments are presented which involve trapping and measuring properties of Th³⁺. Th³⁺ ions are of unique interest in part because they are a promising platform for studying an unusually low-lying nuclear transition in the 229Th nucleus which could eventually be used as an exceptional optical clock.

This study is concerned with the measurement and analysis of the optical absorption spectra of divalent samarium (Sm2+) and ytterbium (Yb2+) ions in potassium and rubidium halide crystals. To incorporate the ions into the crystals, the latter were heated in (the appropriate) metal vapour. The optical absorption spectra of the impurity-doped crystals were measured and are ascribed to 4fN+1 → 4fN5d electronic transitions. For the first time, the optical spectra of Sm2+ and Yb2+ ions in RbBr and RbI crystals are reported. In the case of Yb2+ ions in RbX, (X = Cl,Br,I) crystals, intermediate coupl

The second order rate constants for nucleophilic substitution by methoxide of (Z)- and (E)-O-methylbenzohydroximoyl fluorides [C6H4C(F)=NOCH3] with various substituents on the phenyl ring [p-OCH3 (1h, 2h), p-CH3 (1g, 2g), p-Cl (1f, 2f), p-H (1e, 2e), (3,5)-bis-CF3 (1i, 2i)] in 90:10 DMSO:MeOH have been measured. A Hammett plot of these rate constants vs σ values gave positive ρ values of 2.95 (Z isomer) and 3.29 (E isomer).

Abstract Electron-ion coincidence spectroscopy has been used to study the fragmentation behaviour of small molecules in two distinct cases: to resolve the state specific fragmentation patterns of HgBr₂ and HgCl₂ subsequent to UV ionization, and to distinguish the dissociation behaviour of various chlorinated methanes (CH₃Cl, CH₂Cl₂, CHCl₃ and CCl₄) subsequent to X-ray irradiation. The mercury-compound work has revealed details on the electronic structure and dissociation dynamics of the valence states which were previously unknown. The study on the chlorinated methanes has found new details on

Abstract:

The solid-state mesoscopic solar cells (sMSCs) have been developed as a promising alternative technology to the conventional photovoltaics.

A variety of HTMs and different preparation methods have been studied to overcome these limitations. There are two types of sMSCs included in this doctoral thesis, namely solid-state dye-sensitized solar cells (sDSCs) and organometallic halide perovskite based solar cells. Two different
