Functionalization of Two-Dimensional Transition Metal Dichalcogenides
(Trinity College Dublin. School of Chemistry. Discipline of Chemistry, 2018)Two-dimensional transition metal dichalcogenides (2D TMDs) have aroused enormous interest in recent years due to their intriguing properties and a wide array of potential applications. Further tailoring their colloidal and ... -
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 ... -
Graphene : synthesis and applications
(Trinity College (Dublin, Ireland). School of Chemistry, 2012)Carbon is ubiquitous around us and has been studied extensively, yet it has never failed to surprise us. One of its isomers, graphene was discovered only recently and it was supposed not to exist in free form. Graphene is ... -
