3D Printed Sugar-Sensing Hydrogels
(2020)The ability of boronic acids to reversibly bind diols, such as sugars, has been widely studied in recent years. In solution, through the incorporation of additional fluorophores, this boronic acid-sugar interaction can be ... -
Assembly, disassembly and reassembly: New synthetic approaches towards hybrid, mixed-metal and framework materials
(Trinity College Dublin. School of Chemistry. Discipline of Chemistry, 2018)The research presented in this thesis focuses on the synthesis of novel examples of advanced materials. The project aimed to synthesise new examples of three particular classes of materials; namely organic-inorganic hybrid ... -
Collective capacitive and memristive responses in random nanowire networks: Emergence of critical connectivity pathways
(2018)Random nanowire networks (NWNs) are promising synthetic architectures for non-volatile memory devices and hardware-based neuromorphic applications due to their history-dependent re- sponses, recurrent connectivity, and ... -
Direct laser writing of vapour-responsive photonic arrays
(2021)Using direct laser writing, arrays of optically responsive ionogel structures were fabricated. To demonstrate their responsive nature, visible colour changes in the presence of different solvent vapours were investigated. ... -
"Effective Electrode Length Enhances Electrical Activation of Nanowire Networks: Experiment and Simulation"
(2014)Networks comprised of randomly oriented overlapping nanowires offer the possibility of simple fabrication on a variety of substrates, in contrast with the precise placement required for devices with single or aligned ... -
Generation and Reactivity of Late Transition Metal Hydr(oxo) Complexes Supported by Tripodal Carboxamidate Ligand
(Trinity College Dublin. School of Chemistry. Discipline of Chemistry, 2022)Metal oxo complexes (M=O) are important mediators of oxidative transformations in biological systems.1 Their high reactivity and transient nature have limited their study, with only a handful of well characterized oxo ... -
High-valent dinuclear bis-μ-hydroxo complexes for PCET reactivity
(Trinity College Dublin. School of Chemistry. Discipline of Chemistry, 2021)High valent dinuclear bis-μ-hydroxo transition metals complexes are hypothesised to play a potentially crucial role in several enzymatic mechanism involving their high-valent dinuclear bis-μ-oxo counterparts such as soluble ... -
High-valent nickel complexes supported by pyridinedicarboxamidate ligands in hydrocarbon oxidation reactions
(Trinity College Dublin. School of Chemistry. Discipline of Chemistry, 2017)High-valent M=O and M-O-X complexes are hypothesised to be potent oxidising intermediates both in enzymatic and small-molecule catalysis. In contrast to those from groups 6-8, oxidants that contain late transition metals ... -
In-situ and Operando (Scanning) Transmission Electron Microscopy (S)TEM; a real-time investigation of energy storage devices and materials at the atomic level
(Trinity College Dublin. School of Chemistry. Discipline of Chemistry, 2021)In the modern age of ubiquitous mobile technology, demand for ever increasing battery capacity and size reduction in such devices is a key driving factor for this sector. Technology is currently striving to improve the ... -
An investigation of the electrical behaviours of metallic, semiconducting and core-shell nanowires
(Trinity College Dublin. School of Chemistry. Discipline of Chemistry, 2018)From a device point of view, metallic nanowire networks provide a route to highly transparent, highly conductive, flexible, easy-to-fabricate and low-cost materials. The large-scale integration of these materials in ... -
Metallo-Supramolecular and Bioinspiried Coordination Compounds for H2O Oxidation
(Trinity College Dublin. School of Chemistry. Discipline of Chemistry, 2020)Ever-increasing energy demands and associated climate change issues impose imperative scientific challenges to society. Switching to an economy based on the carbon-free, high density energy carrier H2 represents a promising ... -
Microwave-assisted efficient thiolate-catalysed homo- and crossed intermolecular Tishchenko reactions
(2011)Recently, the first efficient intermolecular crossed Tishchenko reactions were reported. The utility of these processes is curtailed by long reaction times of up to 4 days (at reflux). Herein we report that these reactions ... -
Nonlinear ion drift-diffusion memristance description of TiO2 RRAM devices
(2020)The nature and direction of the hysteresis in memristive devices is critical to device operation and performance and the ability to realise their potential as neuromorphic applications. TiO2 is a prototypical memristive ... -
