On the mass and luminosity within isolated and binary galaxies
(University of St Andrews, 1977) - Thesis
The aim of this project has been to study the detailed mass and luminosity distributions within spiral galaxies, with particular emphasis on the comparison of isolated and binary systems. A large programme of photographic ...
The pyrolysis of ethylbenzene
(University of St Andrews, 1963) - Thesis
Close range passive millimetre wave imaging
(University of St Andrews, 2003-05) - Thesis
This thesis describes the design and construction of a close range Passive Millimetre Wave (PMMW) scanning thermal imager. Whilst close range PMMW imager has previously been applied to concealed weapon detection at ranges ...
Tailoring optical fibers for cell transfection
(University of St Andrews, 2012-11-30) - Thesis
Optical transfection is a promising technique for the delivery of foreign genetic material into cells by transiently changing the permeability of the cell membrane. Of the different optical light sources that have been ...
Emergent states in transition metal oxides
(University of St Andrews, 2013-06-26) - Thesis
Transition metal oxides adopt a wide variety of crystal structures and display a diverse range of physical phenomena from Mott insulating states to electron-nematics to unconventional superconductivity. Detailed understanding ...
A study of the production and application of nonlinear materials for use in frequency doubled dye lasers
(University of St Andrews, 1986-07) - Thesis
A selection of nonlinear materials for use in various frequency-doubled dye lasers is studied. Lithium Formate Monohydrate is operated intracavity in a Coumarin 102 dye laser for the first time. A maximum of 70 microwatts ...
Atmospheric guiding of electromagnetic waves
(University of St Andrews, 1993-07) - Thesis
We propose to alter the propagation conditions experienced by a microwave beam by the generation of a "laser beam atmospheric waveguide". The waveguide is formed by tailored refractive index changes caused by the absorption ...
Non-equilibrium quantum dynamics : interplay of disorder, interactions and confinement
(University of St Andrews, 2019-06-24) - Thesis
The study of collective behaviour in many-body systems often explores fundamentally new ideas absent from the mere constituents of such a system. A paradigmatic model for these studies is the spin-1/2 XXZ chain and its ...
Studies of hollow cathode He-Cd lasers
(University of St Andrews, 1985-07) - Thesis
Novel segmented-electrode discharge tubes which operate as sealed-off He-Cd hollow cathode lasers and which do not require a flowing gas system to distribute cadmium vapour are reported. The electrode geometry is arranged ...
Versatile high resolution dispersion measurements in semiconductor photonic nanostructures using ultrashort pulses
(University of St Andrews, 2007-06-19) - Thesis
This thesis describes the process of developing a robust phase measurement technique with which to analyse semiconductor based devices intended for use in optoelectronic/all optical networks. The devices measured are ...
