The immobilisation of chiral organocatalysts on magnetic nanoparticles: the support particle cannot always be considered inert.
(2011)A systematic study concerning the immobilisation onto magnetic nanoparticles of three useful classes of chiral organocatalyst which rely on a confluence of weak, easily perturbed van der Waals and hydrogen bonding interactions ... -
Immobilized enzyme/single-wall carbon nanotube composites for amperometric glucose detection at very low applied potential
(Royal Chemical Society, 2008)The behaviour of support electrodes modified with randomly dispersed single-wall carbon nanotube meshes containing adsorbed glucose oxidase with respect to amperometric glucose detection at a low potential is demonstrated. -
Immunoliposomes.
(2012)Since their discovery by Bangham about 50 years ago, liposomes have become promising tools in drug delivery systems. This has increased the therapeutic index of many drugs, and offers improved drug targeting and ... -
Impact of Substituents and Nonplanarity on Nickel and Copper Porphyrin Electrochemistry: First Observation of a Cu-II/Cu-III Reaction in Nonaqueous Media
(2014)ABSTRACT Electrochemical studies of the oxidation of dodecasubstitued and highly nonplanar nickel porphyrins in a non-coordinating solvent have previously revealed the first NiIII porphyrin dication. Herein, we investigate ... -
Improvement of Mechanical Properties of Graphene Oxide / Poly(allylamine) Composites by Chemical Crosslinking
(2010)Graphite oxide was prepared by oxidation of graphite using the Hummers method, and its ultrasonication in water yielded dispersed graphene oxide (GO) sheets. These sheets were then crosslinked with a water soluble polymer, ... -
Improving antidepressant drugs: update on recently patented compounds
(2009)Background: According to the World Health Organization, depression is a common condition that affects about 121 million people worldwide. Although the pathophysiological origin of this condition is still unknown, most of ... -
Improving stability of organometallic-halide perovskite solar cells using exfoliation two-dimensional molybdenum chalcogenides
(2020)Organometallic-halide perovskite solar cells (PSCs) are emerging as the most promising next generation solar cell devices. However, the stability is still the main bottleneck of their further development. Here, we introduce ... -
In situ studies of the adsorption kinetics of 4-nitrobenzenediazonium salt on gold
(2011)Self-assembled organic layers are an important tool for modifying surfaces in a range of applications in materials science. Covalent modification of metal surfaces with aryldiazonium cations has attracted much attention ... -
In vitro cytotoxicity of a library of BODIPY-anthracene and -pyrene dyads for application in photodynamic therapy
(2019)The facile synthesis and in vitro activity of a library of heavy atom-free BODIPY-anthracene, -pyrene dyads (BAD-13–BPyrD-19) and a control (BODIPY 20) are reported. We demonstrate that singlet oxygen produced from dyad ... -
Incremental Introduction of Organocatalytic Activity into Conformationally Engineered Porphyrins
(2019)To study the correlation of macrocycle nonplanarity and catalytic activity of free base porphyrins in detail, a series of six tetraphenylporphyrins with graded degree of β‐ethyl substitution (“H2EtxTPPs” 1–6; x = 0, 2, 4, ... -
Influence of carbon nanostructure and oxygen moieties on dopamine adsorption and charge transfer kinetics at glassy carbon surfaces
(2019)Abnormal levels of the neurotransmitter dopamine have been linked to a variety of neurochemical disorders including depression and Parkinson's disease. Dopamine concentrations are often quantified electrochemically using ... -
Influence of fluoro and cyano substituents in the aromatic and antiaromatic characteristics of cyclooctatetraene
(2015)An exhaustive and systematic study of the structural and electronic properties of cyclooctatetraene (COT) upon substitution of hydrogen atoms by fluoro and cyano groups has been carried out in order to analyse the influence ... -
Influence of meso-linker attachment on the formation of core···π interactions in urea-functionalized porphyrins
(2020)The ability to cover the face of a porphyrin macrocycle selectively is an attractive feature for concepts such as catalysis and anion binding that are reliant on porphyrin core interactions. Herein, we have synthesized ... -
Inkjet-defined field-effect transistors from chemical vapour deposited graphene
(2014)In this work, inkjet printing methods are used to create graphene field effect transistors with mobilities up to 3000 cm2 V?1 s?1. A commercially-available chromium-based ink is used to define the device channel by inhibiting ... -
Inosine Can Increase DNA's Susceptibility to Photo-oxidation by a RuII Complex due to Structural Change in the Minor Groove
(2017)Key to the development of DNA-targeting phototherapeutic drugs is determining the interplay between the photoactivity of the drug and its binding preference for a target sequence. For the photo-oxidising lambda-[Ru(TAP)2 ... -
An Insight into Non-Covalent Interactions on the Bicyclo[1.1.1]pentane Scaffold
(2021)Bicyclo[1.1.1]pentane (BCP) is studied extensively as a bioisosteric component of drugs. Not found in nature, this molecular unit approximates the distance of a para-disubstituted benzene which is replaced in medicines as ... -
Insights into the oxygen vacancy filling mechanism in CuO/CeO2 catalysts: A key step toward high selectivity in preferential CO oxidation
(2020)The preferential CO oxidation (CO-PROX) reaction is paramount for the purification of reformate H2-rich streams, where CuO/CeO2 catalysts show promising opportunities. This work sheds light on the lattice oxygen recovery ...
