The effects of residual stress on the material characterisation of individual nanowires
(Trinity College Dublin. School of Chemistry. Discipline of Chemistry, 2017)Many of the techniques currently used to measure the mechanical properties of individual nanowires make the assumption that initially the nanowires are in a zero-stress state. However, due to their small sizes and large ... -

Electrochemistry of the organic molecule methylene blue
(Trinity College (Dublin, Ireland). School of Chemistry, 2008)The first Chapter deals with the general information about chemically modified electrodes, what they are, the development of fabrication techniques, and relevant applications of modified electrodes. This is followed by ... -
Electron and Ion Microscopy Analysis of flexible Super Capacitors and Lithium Ion Battery Electrodes
Super capacitors and lithium ion batteries are both major technology sectors within the renewable energy industry and energy research. They offer applications and products the chance of recharging capability and give ... -
Electronic structure studies of p-type semiconducting oxides
(Trinity College (Dublin, Ireland). School of Chemistry, 2011)Transparent conducting oxides (TCOs) are a unique class of materials which combine the normally mutually exclusive properties of transparency and conduction. Despite the many applications and widespread interest in TCO ... -
Enantioselective organocatalytic cycloaddition reactions between enolisable anhydrides and imines
(Trinity College Dublin. School of Chemistry. Discipline of Chemistry, 2019)Cycloaddition reactions between enolisable anhydrides and imines have long been known as excellent tools for the synthesis of natural products. The racemic version is well known to be capable of providing products with ... -
Enantioselective receptors for anionic species
(Trinity College (Dublin, Ireland). School of Chemistry, 2001)This project aimed to design, synthesise and test neutral, tripodal steroid receptors based on cholic acid 1 that were capable of binding to carboxylates (especially N-acyl-a-aminoacid carboxylates), and differentiating ... -
Enantioselective receptors via one-bead one-compound combinatorial libraries
(Trinity College (Dublin, Ireland). School of Chemistry, 2003)Chapter 1 describes the overall aim of this project, which is to extend the range of steroid-based receptors synthesised by the Davis group, using the combinatorial chemistry approach instead of traditional design and ... -
Energy Storage and Conversion Applications of Transition Metal Oxide Nanoflakes
(Trinity College Dublin. School of Chemistry. Discipline of Chemistry, 2018)In this work, MoO3 and Co(OH)2 were prepared via liquid phase exfoliation (LPE) and tested for application as supercapacitor materials and for a catalyst material for the oxygen evolution reaction (Co(OH)2 only). LPE was ... -
Examination of the organocatalysed reactions between azides and cyclic anhydrides
(Trinity College Dublin. School of Chemistry. Discipline of Chemistry, 2022)Azide is encountered in organic synthesis as both a functional group and as and an ion, and provides a valuable means of incorporating nitrogen into target compounds. The intrinsic nucleophilicity of azides can be beneficial, ... -
Examining spectral converters for emerging photovoltaic technologies
(Trinity College Dublin. School of Chemistry.
