A computational approach to understanding the deNOₓ properties of Rhodium metal
(Trinity College (Dublin, Ireland). School of Chemistry, 2015)The emission of nitrogen oxides (NOx, x = 1, 2) from combustion engines is a significant contributor to acid rain, smog and the enhanced greenhouse effect. The environmental damage these polluntants have caused, as well ... -
A computational exploration of a possible alternative to nucleotides as the basis of a genetic alphabet
(Trinity College (Dublin, Ireland). School of Chemistry, 2012)One of the most fundamental questions in molecular biology is why nature has chosen Adenine (A), Cytosine (C), Guanine (G), Uracil (U)/Thymine (T) for the genetic alphabet. Although much is known about the structure and ... -
A novel synthesis of Loratadine and studies on Stobbe-like condensation reactions
(Trinity College (Dublin, Ireland). School of Chemistry, 2007)Loratadine is one of the best-selling, non-sedative antihistamines worldwide. Numerous papers have been published in academic and patent literature focussing on improvements or alternatives to the original synthesis of ... -
A study of anionic drug transport processes governing passive and enhanced transdermal delivery
(Trinity College (Dublin, Ireland). School of Chemistry, 2001)The research contained herein is directed at defining some of the factors which govern the passive and enhanced transdermal transport of anionic drugs and will extend current knowledge which largely pertains to the analogous ... -
A study of Hydrogen-Deuterium exchange on the photophysical properties of Ruthenium (II) Polypyridyl complexes
(Trinity College (Dublin, Ireland). School of Chemistry, 2002)This main aim of the present study is to investigate the effect of protium-deuterium exchange on the photophysical and excited state energetics of Ru(ll) complexes by UV-Vis absorption, both steady-state and time-resolved ... -
A study of nanowire junctions and their impact on the properties of nanowire networks
(Trinity College (Dublin, Ireland). School of Chemistry, 2015)Nanowire networks are of immense technological interest due to their properties of high transparency, high porosity, flexibility, ease of fabrication, and low cost. Despite the increasing attention these materials continue ... -
A study on novel pyrazine-substituted dithiolene complexes as synthetic models for molybdenum cofactor and facile molybdenum mediated unexpected formation of pentathiepins
(Trinity College (Dublin, Ireland). School of Chemistry, 2014)In the present study, pyrazine (3 and 12) and quinoxaline (4 and 9-11) based compounds were synthesised as precursors for the synthetic analogues of MPT in MoCo. During the attempts to synthesise target model complexes, ... -
A synthetic and photophysical study of ruthenium polypyridyl enantiomers binding to DNA
(Trinity College (Dublin, Ireland). School of Chemistry, 2012)The luminescent ONA probe [Ru(phen)2dppz]2+, ruthenium (bis-1,10-phenanthroline dipyrido[3,2-a:2',3'-c]phenazine, was the first tris-bidentate ruthenium complex to be shown unequivocally to intercalate to DNA, which it ... -
A synthetic development of tetrazines as ligands in Group 8 coordination complexes
(Trinity College (Dublin, Ireland). School of Chemistry, 2009)Chapter 1 describes the synthesis and characterization of a number of novel pyridazinecentred ligands prepared from substituted tetrazines. The use of these compounds as precursors for planar nitrogen containing graphite-type ... -
Acylative cleavage of some cyclic ethers and study of a novel potassium complex
(Trinity College (Dublin, Ireland). School of Chemistry, 2003)Chapter 1 describes ring-opening reactions of cyclic ethers that are described in the literature. The extensive work carried out on tetrahydrofuran is discussed, but it is noted that reactions involving 2,5-dihydrofuran ... -
Additive Manufacturing of Ti3C2-MXene-Functionalized Conductive Polymer Hydrogels for Electromagnetic-Interference Shielding
(2021)The ongoing miniaturization of devices and development of wireless and implantable technologies demand electromagnetic interference (EMI)shielding materials with customizability. Additive manufacturing of conductive ... -
Advanced materials of printed wearables for physiological parameter monitoring
(2020)The consumer demand for flexible wearables has increased rapidly with the advent of recent commercial health monitoring systems. The progress in wearable electronics for monitoring physiological parameters in the healthcare ... -
Advances in the formal cycloadddition reaction between enolisable anhydrides and electrophiles
(Trinity College Dublin. School of Chemistry. Discipline of Chemistry, 2018)Expansion of the scope of catalytic cycloaddition reactions involving enolisable anhydrides to various Michael acceptors as electrophiles has been investigated. The reaction between homophthalic anhydrides and α-β; unsaturated ... -
Aerobic oxidation of NHC-catalysed aldehyde esterifications with alcohols: Benzoin, not the Breslow intermediate, undergoes oxidation
(2013)Benzoin (and neither the Breslow intermediate nor the NHC–aldehyde tetrahedral adduct) has been unambiguously identified as the oxidised species in aerobic NHC-catalyse d aldehyde esterifications.
