An investigation into the catalytic versatility of low toxicity azolium ions
(Trinity College (Dublin, Ireland). School of Chemistry, 2013)A somewhat unexpected observation made by our group that appropriately substituted pyridinium ions were capable of acting as Bronsted acid catalysts in the presence of protic additives (i.e. methanol) caught our attention. ... -
An investigation of the resistive switching in individual and networks of nickel nanowires
(Trinity College (Dublin, Ireland). School of Chemistry, 2014)Nickel/nickel oxide core-shell nanowires can be transformed from their native electrically insulating state to a conductive state by the formation of an atomic scale conductive filament bridging the oxide. This resistive ... -
An ultrafast IR study of cytosine-rich nucleic acids and a photophysical study of porphyrin-nucleic acid systems
(Trinity College (Dublin, Ireland). School of Chemistry, 2011)Work is presented in this thesis on two separate but complementary topics in the photochemistry of nucleic acids. Part one addresses the effect of direct UV excitation on the cytosine derivatives. Cytosine can form mutagenic ... -
