J2suscep: Calculation of magnetic exchange coupling and temperature dependence of magnetic susceptibility
(2021)The field of molecular magnetism has attracted significant interest owing to the rising need to miniaturize magnets. Advances in this field require a deep understanding of the electronic structure of magnets, and computational ... -
A junction level study of the activation process in nanowire networks
(Trinity College Dublin. School of Chemistry. Discipline of Chemistry, 2019)Nanowire networks are promising memristive architectures for neuromorphic computing applications due to their connectivity and neurosynaptic-like behaviours. In this PhD thesis, we demonstrate a self-similar scaling 1 of ... -
Kinetic and mechanistic aspects of the oxygen evolution reaction at hydrous iron oxide films in base
(2013)The oxygen evolution reaction atmulti-cycled iron oxy-hydroxide films in aqueous alkaline solution is discussed. The factors affecting the growth and electrocatalytic properties of the latter are described. In particular, ... -
Konformativer Umbau von Porphyrinen als Rezeptoren mit schaltbaren N‐H⋅⋅⋅X‐Bindungsmodi
(2019)Die Selektivität und funktionale Variabilität von Porphyrinkofaktoren basiert typischerweise auf der Substratbindung durch Metalloporphyrine, wobei die Pyrrolstickstoffatome nur zur Chelatisierung der Metallionen dienen. ... -
Lanthanide directed self-assembly formations of Tb(iii) and Eu(iii) luminescent complexes from tryptophan based pyridyl amide ligands
(2011)The formation of self-assembly complexes between the ligands 1 (SS) and 2 (RR) and terbium or europium was undertaken and shown (using various spectroscopic titrations) to give rise to the exclusive formation of 2 : 1 (L ... -
