Identification and metabolism studies of fluorometabolites from different Streptomyces
(University of St Andrews, 2017) - Thesis
To date, only five fluorinated natural products have been identified. These were isolated from both plants and bacteria. The bacterium Streptomyces cattleya has the ability to biosynthesise fluoroacetate and 4-fluoro-L ...

Investigation of surface modification of perovskite with different catalysts
(University of St Andrews, 2016-11-30) - Thesis
The increasing energy requirements of mankind have stimulated the need to search for renewable clean energy in order to protect the environment. Proton Exchange Membrane Fuel Cells (PEMFC) are one of the most promising ...
α,β-unsaturated acyl ammonium intermediates in asymmetric organocatalysis
(University of St Andrews, 2015-11-30) - Thesis
This thesis details investigations into the generation and synthetic utility of α,β-unsaturated acyl ammonium intermediates using isothioureas as Lewis base organocatalysts to generate a range of heterocyclic products. Initial ...

Sol-gel processing of ruthenium and iridium dioxides
(University of St Andrews, 1998) - Thesis
The synthesis of the Ru₄O₆⁴⁺(aq) ion and attempts to produce derivative complexes of it are explored. Although crystals suitable for examination by single crystal X-Ray crystallography were not obtained, the core structure ...
Metal organic frameworks as Lewis acid catalysts
(University of St Andrews, 2014-12-01) - Thesis
Lewis acids are widely used in the pharmaceutical industry, generally homogeneously, to perform reactions such as C-C or C=N bond formation and acetalisation. Typically, metal salts such as those of Ti, Fe and especially ...
