Dipyrrinato-Iridium(III) Complexes for Application in Photodynamic Therapy and Antimicrobial Photodynamic Inactivation
(2021)The generation of bio-targetable photosensitizers is of utmost importance to the emerging field of photodynamic therapy and antimicrobial (photo-)therapy. A synthetic strategy is presented in which chelating dipyrrin ... -
Direct Laser Writing of Four-Dimensional Structural Color Microactuators Using a Photonic Photoresist
(2020)With the advent of direct laser writing using two-photon polymerization, the generation of high-resolution three-dimensional microstructures has increased dramatically. However, the development of stimuli-responsive ... -
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. ... -
Direct Laser Writing to Generate Molds for Polymer Nanopillar Replication
(2020)Herein we exploit direct laser writing as a means to fabricate negative masters for the generation of polymeric nanopillars, via replica molding. Through optimization of design parameters, fabrication configuration, and ... -
Direct observation by time-resolved infrared spectroscopy of the bright and the dark excited states of the [Ru(phen)2(dppz)]2+ light-switch compound in solution and when bound to DNA
(2016)The [Ru(phen)2(dppz)]2+ complex (1) is non-emissive in water but is highly luminescent in organic solvents or when bound to DNA, making it a useful probe for DNA binding. To date, a complete mechanistic explanation for ... -
Discerning activity and inactivity in earth-abundant molecular oxygen evolution catalysts
(2020)Most computational studies on the oxygen evolution reaction (OER) focus on systems which are known to catalyze this process experimentally. This work computationally examines a number of earth‐abundant metal (M=Mn, Fe, Co, ... -
Displacement assay detection by a dimeric lanthanide luminescent ternary Tb(iii)-cyclen complex: High selectivity for phosphate and nitrate anions
(2014)The luminescent dimeric ternary lanthanide–cyclen complexes (2-(Ln.1)2; Ln = Tb/Eu) were designed and both their self-assembly formation and their ability to detect anions via displacement assays were investigated using ... -
"The dominant role of the solvent-water interface in water droplet templating of polymers"
(2013)We investigate the formation of microstructured polymer networks known as Breath Figure templated structures created by the presence of water vapour over evaporating polymer solutions. We use a highly controlled experimental ... -
Dramatic mechanistic switch in Sn/AuI group exchanges: Transmetalation vs. oxidative addition
(2016)The mechanism of Ph/X exchange in reactions involving SnPh(n)Bu3 and [AuXL] complexes switches dramatically from the usual concerted mechanism involving Ar/X mixed bridges when X = Cl, to an unexpected oxidative ... -
Dual-binding conjugates of diaromatic guanidines and porphyrins for recognition of G-quadruplexes
(2020)The first conceptualised class of dual-binding guanine quadruplex binders has been designed, synthesised and biophysically studied. These compounds combine diaromatic guanidinium systems and neutral tetra-phenylporphyrins ... -
Dynamic in-situ sensing of fluid-dispersed 2D materials integrated on microfluidic Si chip
(2017)In this work, we propose a novel approach for wafer-scale integration of 2D materials on CMOS photonic chip utilising methods of synthetic chemistry and microfluidics technology. We have successfully demonstrated that this ... -
Dynamics of ultrafast dissociation of hydrogenic molecules by resonant antibonding core electron excitation: Conclusions from detuning dependence of H+- kinetic energy distributions from condensed films
(Elsevier, 2011)The ultrafast dissociation dynamics of condensed water and ammonia by resonant core electron excitations have been studied by measuring the kinetic energy distributions of H+-ions desorbed by [N1s]4a1 and [O1s]4a1 excitations ... -
Edge reactivity and water-assisted dissociation on cobalt oxide nanoislands
(2017)Transition metal oxides show great promise as Earth-abundant catalysts for the oxygen evolution reaction in electrochemical water splitting. However, progress in the development of highly active oxide nanostructures is ... -
Effect of carbon nanotube surface modification on dispersion and structural properties of electrospun fibers
(2009)Covalent surface modification of multiwall carbon nanotubes leads to enhanced nanotube dispersion in the polymer. Despite this, the mechanical properties of electrospun fibers made of polymethylmethacrylate containing ... -
Effect of chiral ligand concentration and binding mode on chiroptical activity of CdSe/CdS quantum dots
(2019)Chiroptically active fluorescent semiconductor nanocrystals, quantum dots (QDs), are of high interest from a theoretical and technological point of view, because they are promising candidates for a range of potential ... -
