Dataset for 'Controlling the fluorescence and room-temperature phosphorescence behaviour of carbon nanodots with inorganic crystalline nanocomposites'
No full textDataset for Tuning Room-Temperature Phosphorescence from Carbon Dots in Inorganic Crystalline Nanocomposites. Carbon dots are occluded in calcite single crystal hosts and analysed by confocal microscopy, pXRD, SS-PL, phosphorescence spectroscopy, video stroboscopy, time-resolved phosphorescence microscopy, Raman spectroscopy, SEM, FLIM and quantitative analysis. The activation of room-temperature phosphorescence was demonstrated, and the control of the host over photoluminescent behaviour in CDs was explored. The dataset shown here was published in a paper with the same title
Data associated with "Sub-Nanometer Thick Gold Nanosheets as Highly-efficient Catalysts"
No full textTwo-dimensional metal nanomaterials offer exciting prospects in terms of their properties and functions. However, the ambient aqueous synthesis of atomically-thin, two-dimensional (2D) metallic nanomaterials represents a significant challenge. Herein, freestanding and atomically-thin gold nanosheets with a thickness of only 0.47 nm (two atomic layers thick) were synthesized via a one-step aqueous approach at 20°C, using Methyl Orange as a confining agent. Owing to the high surface-area-to-volume ratio, abundance of unsaturated atoms exposed on the surface and large interfacial areas arising from their ultrathin 2D nature, the as-prepared Au nanosheets demonstrate excellent catalysis performance in the model reaction of 4-nitrophenol reduction, and remarkable peroxidase-mimicking activity which enables a highly-sensitive colorimetric sensing of H2O2 with a detection limit of 0.11 µM. This work represents the first fabrication of freestanding 2D gold with a sub-nanometer thickness, opens up an innovative pathway towards atomically-thin metal nanomaterials that can serve as model systems for inspiring fundamental advances in materials science, and hold potential across a wide region of applications

Dataset associated with 'Modelling urban airflow and natural ventilation using a GPU-based lattice-Boltzmann method'
No full textSimulation of urban airflow and ventilation potential is desirable for building design, however the complex and transient nature of flows in urban environments makes this a challenging task. This study aims to evaluate the capability of a lattice-Boltzmann method (LBM) code deployed on a graphical processing unit (GPU) using a large eddy sub-grid turbulence model for cross-flow ventilation of an idealised cubical building at wind-tunnel scale. ANSYS Fluent is used as a numerical comparison. Façade pressure and ventilation of the cube are investigated for parallel and perpendicular wind directions with the building in isolation and regular array format. Pressures, velocities and ventilation rates are compared to experimental data from wind tunnel and full-scale experiments of the Silsoe cube. Simulations compare favourably with experimental values and between each other. When the cube was surrounded by other cubes, simulations suggest that vortex shedding from up-wind buildings provides pulsating ventilation, improving airflow ingress in the parallel wind cases. A parametric study showed that doubling surrounding building height had a small negative effect on ventilation but was mitigated by high levels of downdraft and flow fluctuations in the vertical plane. Comparatively, doubling the central building height had a net positive effect but caused high internal airspeeds for both angles. The LBM code running on one GPU was several orders of magnitude faster than Fluent with similar accuracy. Simulation time using the LBM approach was several orders of magnitude lower than Fluent
