Calibration of Nonstationary Gas Sensors Based on Two-Dimensional Materials
(2020)Two-dimensional materials (2DMs) have high potential in gas sensing, due to their large surface-to-volume ratio. However, most sensors based on 2DMs suffer from the lack of a steady state during gas exposure, hampering ... -
Capacitive storage at nitrogen doped amorphous carbon electrodes: structural and chemical effects of nitrogen incorporation
(2019)Nitrogen incorporated carbon materials play an important role in electrochemical energy conversion technologies from fuel cells to capacitive storage devices. This work investigates the effects of nitrogen incorporation ... -
Carbazole-linked porphyrin dimers for organic light emitting diodes: Synthesis and initial photophysical studies
(2011)Carbazole linked porphyrin dimers were synthesized in good yields via stepwise Suzuki coupling reactions using bromoporphyrins and borylated carbazoles as the precursors, the latter of which were synthesized via known ... -
Carbohydrate Coatings via Aryldiazonium Chemistry for Surface Biomimicry
(2013)Carbohydrates are extremely important biomolecules and their immobilization onto solid surfaces is of interest for the development of new biomimetic materials and of new methods for understanding processes in glycobiology. ... -
Carbon nano-onions as non-cytotoxic carriers for cellular uptake of glycopeptides and proteins
(MDPI, 2019)Carbon nano-onions (CNOs) possess favorable properties that make them suitable for biomedical applications, including their small size, ready surface modification, and good biocompatibility. Here, we report the covalent ... -
Carbon nanotube based modified electrode biosensors. Part 1. Electrochemical studies of the flavin group redox kinetics at SWCNT/glucose oxidase composite modified electrodes.
(Electrochemical Science Group, 2008)The redox behaviour of glucose oxidase adsorbed on glassy carbon electrodes which have been modified with a dispersed mesh of single wall carbon nanotubes is probed both qualitatively and quantitatively using cyclic ... -
Carboxamidate Ligand Noninnocence in Proton Coupled Electron Transfer
(2019)Recent breakthroughs have brought into question the innocence (or not) of carboxamidate donor ligands in the reactivity of high-valent oxidants. To test the reactivity properties of high-valent carboxamidate complexes, ... -
Catalytic (asymmetric) methylene transfer to aldehydes
(2010)An investigation into the poor activity of sulfides as catalysts for sulfonium-ylide-mediated methylene transfer to aldehydes has indicated that ylide formation is the problematic catalytic cycle step. Alkylation with ... -
Catalytic, asymmetric azidations at carbonyls: achiral and meso-anhydride desymmetrisation affords enantioenriched ?-lactams
(2022)An unprecedented organocatalytic process involving the asymmetric addition of azide to meso-anhydrides has been developed, promoted by novel sulfamide-substituted Cinchona alkaloid-based catalysts. Readily available glutaric ... -
Catalytic, enantio- and diastereoselective synthesis of gamma-butyrolactones incorporating quaternary stereocentres
(2012)A new, highly enantio- and diastereoselective catalytic asymmetric formal cycloaddition of aryl succinic anhydrides and aldehydes which generates paraconic acid (y-butyrolactone) derivatives is reported. -
Catechol oxidase activity of comparable dimanganese and dicopper complexes
(2018)Synthetic CuII2 complexes have been widely investigated as model systems for catechol oxidase enzymes. The catechol oxidase reactivity of MnII2 complexes has been less explored, and the effect of metal substitution in ... -
Cation-π interactions: complexes of Guanidinium and simple aromatic systems
(2011)We have theoretically studied, in gas phase and using PCM-water solvation, the complexes established by the biologically relevant guanidinium cation and simple aromatic systems (benzene, naphthalene and pyridine). In gas ... -
Cell death in photodynamic therapy: From oxidative stress to anti-tumor immunity
(2019)Photodynamic therapy is a promising approach for cancer treatment that relies on the administration of a photosensitizer followed by tumor illumination. The generated oxidative stress may activate multiple mechanism of ... -
Cell Proliferation Tracking Using Graphene Sensor Arrays
(2012)The development of a novel label-free graphene sensor array is presented. Detection is based on modification of graphene FET devices and specifically monitoring the change in composition of the nutritive components in ... -
CeO2 catalysed conversion of CO, NO2 and NO from first principles energetics
(2006)First principles calculations using density functional theory with corrections for on-site Coulomb interactions (DFT + U) are presented in which we compute the energy for the conversion of CO to CO2, NO2 to NO and NO to ... -
Ceria co-doping: Synergistic or average effect?
(2014)Ceria (CeO2) co-doping has been suggested as a means to achieve ionic conductivities that are significantly higher than those in singly doped systems. Rekindled interest in this topic over the last decade has given rise ... -
