Emergence of cooperative dynamics in fully packed classical dimers

Tom Oakes, Juan Garrahan & Stephen Powell
We study the behavior of classical dimer coverings of the square lattice - a paradigmatic model for systems subject to constraints - evolving under local stochastic dynamics, by means of Monte Carlo simulations and theoretical arguments. We observe clear signatures of correlated dynamics in both global and local observables and over a broad range of time scales, indicating a breakdown of the simple continuum description that approximates well the statics. We show that this collective...

Illness beliefs predict mortality in patients with diabetic foot ulcers

Kavita Vedhara
Background: Patients’ illness beliefs have been associated with glycaemic control in diabetes and survival in other conditions. Objective: We examined whether illness beliefs independently predicted survival in patients with diabetes and foot ulceration. Methods: Patients (n=169) were recruited between 2002 and 2007. Data on illness beliefs were collected at baseline. Data on survival were extracted on 1st November 2011. Number of days survived reflected the number of days from date of recruitment to 1st November...

Surface-directed modulation of supramolecular gel properties

Mischa Zelzer & Maria Marlow
Supramolecular materials are widely studied and used for a variety of applications; in most applications, these materials are in contact with surfaces of other materials. Whilst much focus has been placed on elucidating factors that affect supramolecular material properties, the influence of the material surface on gel formation is poorly characterised. Here, we demonstrate that surface properties directly affect the fibre architecture and mechanical properties of self-assembled cytidine based gel films.

The influence of floodplain restoration on sediment dynamics on an urban river

Nigel Wright
Urbanisation affects both the volume and timing of sediment delivery in the catchment. This study presents influence of floodplain restoration on the sediment dynamics in the highly urbanised catchment, Johnson Creek, Portland, Oregon. The study incorporates a two-dimensional hydro-morphodynamic model for predicting flow and suspended sediment dynamics in the downstream of Johnson Creek, the East Lents reach, where the bank of river has been reconfigured to reconnect to a restored floodplain. The simulation scenario include...

Quantum confinement and photoresponsivity of β-In2Se3 nanosheets grown by physical vapour transport

Nilanthy Balakrishnan, Peter Beton & Amalia Patane
We demonstrate that β-In2Se3 layers with thickness ranging from 2.8 – 100 nm can be grown on SiO2/Si, mica and graphite using a physical vapour transport method. The β-In2Se3 layers are chemically stable at room temperature and exhibit a blue-shift of the photoluminescence emission when the layer thickness is reduced, due to strong quantum confinement of carriers by the physical boundaries of the material. The layers are characterized using Raman spectroscopy and X-ray diffraction from...

Chain length affects pancreatic lipase activity and the extent and pH–time profile of triglyceride lipolysis

Pavel Gershkovich & Paloma Benito
Triglycerides (TG) are one of the most common excipients used in oral lipid-based formulations. The chain length of the TG plays an important role in the oral bioavailability of the co-administered drug. Fatty acid (FA) chain-length specificity of porcine pancreatic lipase was studied by means of an in vitro lipolysis model under bio-relevant conditions at pH 6.80. In order to determine the total extent of lipolysis, back-titration experiments at pH 11.50 were performed. Results suggest...

Measuring the reactivity of a silicon-terminated probe

Adam Sweetman
Raw data files used to construct paper figures: In this study we probe the reactivity of silicon clusters at the end of a scanning probe tip by examining their interaction with closed shell fullerene molecules. Counter to intuitive expectations, many silicon clusters do not react strongly with the fullerene cage, and we find that only specific highly oriented clusters have sufficient reactivity to break open the existing carbon-carbon bonds.

Multiple rainfall event pollution transport by Sustainable Drainage Systems: the fate of fine sediment pollution

Scott Arthur
A key design criterion of sustainable urban drainage systems is to mitigate urban stormwater pollution. Current research defines sustainable urban drainage systems (SuDS) pollutant treatment efficiency through the detention of total suspended solids, urban nutrients and heavy metal pollutants within the system during a design flow event, with research focusing on sand (>2mm) sediment movement. The impact of multiple rainfall-runoff events on the fine sediment (<2mm) treatment efficiency of SuDS is not yet well defined...

Processing and properties of PLA-HA nanocomposites: the effect of particle morphology and dispersants

Magdalena M. Tomczynska, Davide De Focatiis, Michael Ward, Gabriel Y. H. Choong, Alessia Canciani, Kirsty Walton, David M. Grant, Derek J. Irvine & Andrew J. Parsons
The load bearing capacity of biodegradable polymeric medical devices remains limited; an improvement in mechanical properties is desirable to widen the range of applications. Incorporation of nanoparticles is explored to increase the mechanical properties of the base matrix whilst maintaining desirable polymeric processing routes. Various nanomaterials have been investigated for polylactic acid (PLA) reinforcement for orthopaedic applications; hydroxyapatite (HA), the main inorganic constituent of bone, is one of the most promising bioresorbable nanofillers. However, uncoated...

Strain-engineered graphene grown on hexagonal boron nitride by molecular beam epitaxy

Peter Beton, Alex Summerfield & Andrew Davies
Graphene grown by high temperature molecular beam epitaxy on hexagonal boron nitride (hBN) forms continuous domains with dimensions of order 20 μm, and exhibits moiré patterns with large periodicities, up to ~30 nm, indicating that the layers are highly strained. Topological defects in the moiré patterns are observed and attributed to the relaxation of graphene islands which nucleate at different sites and subsequently coalesce. In addition, cracks are formed leading to strain relaxation, highly anisotropic...

Age-related changes to human stratum corneum lipids detected using ToF-SIMS following in vivo sampling

Nichola Starr, Daniel Johnson & David Scurr
This work demonstrates the ability to detect changes in both quantity and spatial distribution of human stratum corneum (SC) lipids from samples collected in vivo. The SC functions as the predominant barrier to the body, protecting against the penetration of xenobiotic substances. Changes to the SC lipid composition have been associated with barrier impairment and consequent skin disorders and it is therefore important to monitor and quantify changes to this structure. This work demonstrates the...

Resonant Zener tunnelling via zero-dimensional states in a narrow gap diode

Amalia Patane & Davide Maria Di Paola
The data contains measured current-voltage characteristics and simulated energy band profiles describing Zener tunnelling via zero-dimensional states in a narrow gap diode. In our devices, a narrow quantum well of the mid-infrared (MIR) alloy In(AsN) is placed in the intrinsic (i) layer of a p-i-n diode. The incorporation of nitrogen in the quantum well creates states that are localized on nanometer lengthscales. These levels provide intermediate states that act as “stepping stones” for electrons tunnelling...

The impacts of natural flood management and urban catchment composition on stormwater quality and in-channel sediment quality

Robert Grabowski & Scott Arthur
Natural Flood Management (NFM) techniques aim to reduce downstream flooding by storing and slowing the flow of stormwater to river channels. These techniques include a range of measures, including setback stormwater outfalls and the physical restoration of channels and floodplains, to improve the natural functioning of catchments. An additional benefit of NFM measures is the potential reduction in sediment and pollutant delivery to the channel. Urban development releases a variety of heavy metal and nutrient...
