Effect of external magnetic fields on electron transfer and ion pairing dynamics at ferrocenyl alkane thiol SAM/solution interfaces
(2010)The redox behaviour of ferrocene alkane thiol self assembled monolayer modified electrodes in contact with aqueous perchlorate solutions both in the absence of and in the presence of an external magnetic field is examined ... -
Electronic Structure and Lattice Vibrations of Ca2CuO2Cl2: a hybrid density functional study
(2008)The electronic structure and phonon modes of Ca 2 CuO 2 Cl 2 have been calculated using hybrid density functional theory HDFT methods. The material is correctly predicted to be an antiferromagnetic insulator with ... -
Enhanced brightness in organic light-emitting diodes using a carbon nanotube composite as an electron-transport layer
(2001)We have studied the effects of using a composite fabricated from carbon nanotubes and a host polymer, poly(m-phenylene-vinylene-co-2,5-dioctyloxy-p-phenylene-vinylene) (PmPV), as an electron-transport layer in organic ... -
Enhancement in Solar Cells Efficiency by Luminescent Down-Shifting layers
(2013)In this paper, core-shell semiconductor quantum dots (QDs) CdSeS/ZnS with emission at 490 nm and 450 nm were investigated for their use in luminescent down-shifting (LDS) layers. Luminescent quantum yield ... -
Environmental Tobacco Smoke in Designated Smoking Areas in the Hospitality Industry: Exposure Measurement, Exposure Modelling & Policy Assessment
(2012)Tobacco control policy has been enacted in many jurisdictions worldwide banning smoking in the workplace. In the hospitality sector many businesses such as bars, hotels and restaurants have installed designated smoking ... -
Evaluation of Ontology Mapping Representations
(2009)A common approach to mitigate the effects of ontology heterogeneity is to discover and express the specific correspondences between different ontologies. An open research question is: how should such ontology mappings be ... -
Experimental observation of scaling laws for alternating current and direct current conductivity in polymer-carbon nanotube composite thin films
(2002)Alternating current (ac) and direct current (dc) conductivities have been measured in polymer-nanotube composite thin films. This was carried out for a range of concentrations of multiwall nanotubes in two polymer hosts, ... -
An experimental-numerical study of heat transfer enhancement in a minichannel using asymmetric pulsating flows
(2023)The development of current and next generation high performance electronic devices has led to miniaturization in more densely packed spaces. The increasing power levels has resulted in ever-increasing heat flux densities ... -
Expression of multidrug resistance markers ABCB1 (MDR-1/ Pgp) and ABCC1 (MRP-1) in renal cell carcinoma
(2009)Background Renal cell carcinoma patients respond poorly to conventional chemotherapy, this unresponsiveness may be attributable to multidrug resistance (MDR). The mechanisms of MDR in renal cancer are not fully understood ... -
fMRI activation during response inhibition and error processing: the role of the DAT1 gene in typically developing adolescents and those diagnosed with ADHD
(2011)The DAT1 gene codes for the dopamine transporter, which clears dopamine from the synaptic cleft, and a variant of this gene has previously been associated with compromised response inhibition in both healthy and clinical ... -
Folic acid modified gelatine coated quantum dots as potential reagents for in vitro cancer diagnostics.
(2011)BACKGROUND: Gelatine coating was previously shown to effectively reduce the cytotoxicity of CdTe Quantum Dots (QDs) which was a first step towards utilising them for biomedical applications. To be useful they also need ... -
Friedel Oscillations in graphene: Sublattice Asymmetry in Doping
(2013)Symmetry breaking perturbations in an electronically conducting medium are known to produce Friedel oscillations in various physical quantities of an otherwise pristine material. Here we show in a mathematically transparent ... -
Genome scan meta-analysis of schizophrenia and bipolar disorder, part III: Bipolar disorder
(2003)Genome scans of bipolar disorder (BPD) have not produced consistent evidence for linkage. The rank-based genome scan meta-analysis (GSMA) method was applied to 18 BPD genome scan data sets in an effort to identify regions ... -

Hydrogen evolution across nano-Schottky junctions at carbon supported MoS 2 catalysts in biphasic liquid systems
(2012)The activities of a series of MoS 2-based hydrogen evolution catalysts were studied by biphasic reactions monitored by UV/Vis spectroscopy. Carbon supported MoS 2 catalysts performed best due to an abundance of catalytic ... -
Impact of bias current distribution on the noise figure and power saturation of a multicontact semiconductor optical amplifier
(2011)We present an experimental investigation of a multicontact semiconductor optical amplifier. This first-generation device allows for direct control of the carrier density profile along the length of the waveguide. This is ... -
Impaired capacity for autonoetic reliving during autobiographical event recall in mild Alzheimer's disease
(2011)The capacity to mentally travel back in time and relive past events via autonoetic consciousness has been shown to be compromised even in the early stages of Alzheimer's disease (AD). To further understand the unravelling ... -
Improving the Mechanical Properties of Single-Walled Carbon Nanotube Sheets by Intercalation of Polymeric Adhesives
(2003)Organic polymers, such as poly(vinyl alcohol), poly(vinyl pyrrolidone), and poly(styrene), were intercalated into single-walled carbon nanotube sheets by soaking the sheets in polymer solutions. Even for short soak times, ...
