Bioinspired electro-permeable glycans on carbon: Fouling control for sensing in complex matrices
(2020)The effect of glycan adlayers on the electrochemical response of glassy carbon electrodes was studied using standard redox probes and complex aqueous matrices. Aryldiazonium cations of aryl-lactoside precursors were used ... -
BODIPY-Pyrene and Perylene Dyads as Heavy-Atom-Free Singlet Oxygen Sensitizer
(2018)Dyads combining BODIPY as an electron acceptor and pyrene or perylene as electron donor subunits were prepared and their photophysical properties were studied by steady‐state and transient spectroscopy. Depending on the ... -
The btp [2,6-bis(1,2,3-triazol-4-yl)pyridine] binding motif: A new versatile terdentate ligand for supramolecular and coordination chemistry
(2014)Ligands containing the btp [2,6-bis(1,2,3-triazol-4-yl)pyridine] motif have appeared with increasing regularity over the last decade. This class of ligands, formed in a one pot ‘click’ reaction, has been studied for various ... -
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 ... -
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 ... -
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 ... -
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 ... -
Characterization of graphene-silicon Schottky barrier diodes using impedance spectroscopy
(2013)We investigate the interface characteristics of graphene-silicon Schottky barrier diodes using dc current-voltage measurements and ac impedance spectroscopy (IS). Diode parameters, including the ideality factor and the ... -
Charge localization increases chemical expansion in cerium-based oxides
(2012)In this work, we demonstrate the mechanism by which electronic charge localization increases the chemical expansion coefficient in two model systems, CeO 2-? and BaCeO 3-?. Using Density Functional Theory calculations, we ... -
Charge-modulated self-assembly and growth of conjugated polyelectrolyte-polyoxometalate hybrid networks.
(2014)Self-assembly of an anionic polyoxometalate with cationic conjugated polyelectrolytes leads to hybrid supramolecular networks whose dimensionality is controlled by the chain length and steric charge distribution. -
Chemical synthesis and medicinal applications of glycoporphyrins
(2015)This review presents an in-depth overview of the modification of porphyrins with bioconjugates and their applications in medicine today. Porphyrin bioconjugates ranging from nucleotides to steroids are under active ... -
Chemical Synthesis in Solution and Porphyrin Nanostructures on Surfaces - Similar Concepts, Different Results.
(2013)The chemistry of porphyrins is reaching out to more complex and ever larger polyporphyrin arrays. In solution the synthesis of porphyrin arrays is greatly aided by recent advances in organometallic chemistry which now ... -
Chemically Modulated Graphene Diodes
(2013)We report the manufacture of novel graphene diode sensors (GDS), which are composed of monolayer graphene on silicon substrates, allowing exposure to liquids and gases. Parameter changes in the diode can be correlated with ... -
Chiral quantum supercrystals with total dissymmetry of optical response
(2016)Since chiral nanoparticles are much smaller than the optical wavelength, their enantiomers show little difference in the interaction with circularly polarized light. This scale mismatch makes the enhancement of enantioselectivity ... -
