A study of the oxidation of polymers using excited oxygen species
(University of St Andrews, 1972) - ThesisIn this thesis, the work is concerned with the effects of exposing various polymers, both in the solid state and in solution, to 'active' oxygen species. In this case the active species are mainly 1△g molecular oxygen and ... -
Biosynthesis and enzymology of fluorometabolite production in Streptomyces cattleya
(University of St Andrews, 2003) - ThesisOrganofluorine compounds are very rare in nature when compared with other organohalogens and the way by which fluorine is inserted into these compounds was unknown before the investigations described in this thesis. The ... -
Quantum chemical studies of intermediates in nitrosamine carcinogenesis
(University of St Andrews, 1986) - ThesisN-Nitrosamines are chemical compounds which are frequently carcinogenic. They may be formed from naturally occurring precursors under a variety of conditions. Despite much experimental study, many of these intermediates ... -
Synthesis and characterisation of porous polymers
(University of St Andrews, 2003) - ThesisHighly porous silsesquioxane based copolymers, deriving from vinyl and hydridosilsesquioxane monomers, have been synthesised. These materials have been characterised in order to determine their chemical structure, with ... -
Hydrogen bonding in sterically-hindered ferrocenes and related systems
(University of St Andrews, 1995) - ThesisThe aims of this project are the synthesis and characterisation of new types of chemical structure containing the electroactive ferrocene nucleus. There are three main strands to this work: (i) coupling reactions of ...
