title: Dataset for 'Prevention of Encrustation and Blockage of Urinary Catheters by Proteus mirabilis via pH-Triggered Release of Bacteriophage'

description: The crystalline biofilms of Proteus mirabilis can seriously complicate the care of patients undergoing long-term indwelling urinary catheterisation. Expression of bacterial urease causes a significant increase in urinary pH, leading to the supersaturation and precipitation of struvite and apatite crystals. These crystals become lodged within the biofilm, resulting in the blockage of urine flow through the catheter.

This dataset presents the effect on bacterial growth, and hence time to blockage of urinary catheters as a result of an infection-responsive surface coating, which releases a therapeutic dose of bacteriophage in response to elevated urinary pH. The coating employs a dual-layered system comprising of a lower hydrogel ‘reservoir’ layer impregnated with bacteriophage, capped by a ‘trigger’ layer of the pH-responsive polymer poly(methyl methacrylate-co-methacrylic acid) (EUDRAGIT®S 100). Evaluation of prototype coatings using a clinically reflective in vitro bladder model resulted in the doubling of catheter blockage time under conditions of established infection in response to a 'burst release' of bacteriophage.

The data presented shows the time to blockage for both models infected with urease positive and negative bacteria, as well as the change in bacterial CFU/ml and bacteriophage PFU/ml with time. Samples taken directly from the bladder at time intervals show the simultaneous reduction in bacterial count, accompanied by an increase in viral concentration. Atomic absorption spectroscopy data also presented quantifiably shows the reduction in crystalline biofilm biomass after bacteriophage release within the bladder.

title: Dataset for 'An in-situ infection detection sensor coating for urinary catheters'

description: We describe a novel infection-responsive coating for urinary catheters that provides a clear visual early warning of Proteus mirabilis infection and subsequent blockage. The crystalline biofilms of P. mirabilis can cause serious complications for patients undergoing long-term bladder catheterisation. Healthy urine is around pH 6, bacterial urease increases urine pH leading to the precipitation of calcium and magnesium deposits from the urine, resulting in dense crystalline biofilms on the catheter surface that blocks urine flow. The coating is a dual layered system in which the lower poly(vinyl alcohol) layer contains the self-quenching dye carboxyfluorescein. This is capped by an upper layer of the pH responsive polymer poly(methyl methacrylate-co-methacrylic acid) (Eudragit S100®). Elevation of urinary pH (>pH 7) dissolves the Eudragit layer, releasing the dye to provide a clear visual warning of impending blockage.

This dataset present raw data from the trial of the prototype catheter coatings within the in vitro bladder model system. The data presented details the change in bacterial biomass within residual bladder urine over time, as well as the consequent changes in urine pH and fluorescence output as a result of coating dissolution.

title: Dataset for 'Development of an Infection-Responsive Fluorescent Sensor for the Early Detection of Urinary Catheter Blockage'

description: Formation of crystalline biofilms following infection by Proteus mirabilis can lead to encrustation and blockage of long-term indwelling catheters, with serious clinical consequences. We describe a simple sensor, placed within the catheter drainage bag, to alert of impending blockage via a urinary colour change.

The dataset presented shows data from the characterisation and testing of the prototype sensors, Including: investigation into the fluorescent properties of 5(6)-carboxyfluorescein (CF) (fluorescence output vs CF concentration and fluorescence output vs solution pH), change in pH vs time for P. mirabilis subcultures and bacterial supernatants, corresponding dye release vs time, as well as data from the testing of the sensors within the in vitro bladder model system (change in fluorescence output within the drainage bag and approximate CF concentration with time). Investigation into the initial dye release kinetics was also undertaken and the data presented in this dataset. Standard curves at three different pHs (6,7 and 8) are presented as well as the overlaid release profiles over time.
description: A plate reader (BMG Labtech) was used to quantify fluorescent output throughout these experiments. 

Basic bacterial subculturing was used from a single bacterial colony, to create subcultures. 

To create supernatants, overnight cultures were centrifuged at 4000 rpm for 10 minutes and the supernatant separated from the pellet.

title: Raw Data for Azetidinium Lead Iodide for Perovskite Solar Cells

description: Here we prepare azetidinium lead iodide for the first time. Azetidinium lead iodide is a stable, bright orange material which does not appear to form a 3D or a 2D perovskite. It was successfully used as the absorber layer in solar cells. We also show that it is possible to make mixed cation devices by adding the azetidinium cation to methylammonium lead iodide. Mixed azetidinium-methylammonium cells show improved performance and reduced hysteresis compared to methylammonium lead iodide cells.

This dataset includes all structural and electrochemical raw data, including thin film XRD, UV/Vis, Cyclic Voltammetry and Mott Schottky measurements. It also includes the main parameters (Efficiency, Open Circuit Voltage, Short Circuit Current Density, Fill Factor) for all those made. The raw data includes JV curve data of the best pixel from each set, a stabilised efficiency measurement for the  MAPI, A1 and A2 cell and an EQE measurement of the best overall pixel.

title: Data for 'Toward healthy housing for the displaced'

description: The population of people living in temporary settlements after disasters is in the millions and the average stay in these settlements exceeds a decade. The issue of the thermal performance of shelters and their impact on health is generally overlooked by the academic community. In an attempt to rebalance this situation, thermal surveys were conducted in two refugee camps in Jordan. Thermal monitoring data of the shelters over two weeks in summer and winter are presented in this dataset.
description: Environmental monitoring data (temperature C and relative humidity %) was collected using I-buttons (DS1923-F5 Temperature and humidity logger)  in 5 shelters in each camp, over 10 days in summer and winter. measurements were recorded at half an hour intervals. The I-buttons were placed in the middle of the one room shelter at 1.5m high.

A weather station was positioned on the roof a UNHCR caravan, temperature and humidity measurements were taken every minute and an average recoded every 30 minutes.

title: Dataset for "A multi-variable study of factors affecting the complex resistivity of conductive mortar"

description: Data collected as part of a study into mortar conductivity. Consists of impedance data organised by mix and date, taken using an Agilent E4990A. Some physical information about the mixes is included since it was recorded at the same time. An included README file gives more details.
description: From the associated paper:
"Measurements were taken using an Agilent E4990A impedance analyser. Each mortar cube was removed from the water and surface dried using a cloth before measurements were taken. At this point the length of the cube was verified to reduce the risk of mistaken identity. Surface temperature was not controlled when out of the water, but was recorded before measurement. The surface temperatures range from 16 to 24C with the average being 20C. These temperatures were not used in the analysis but are included in the online data for the study.
Measurements were taken at 7, 14, 21, 28, and 35 days after casting the mortar. Stainless steel electrodes were clamped to the cubes and connected to the impedance analyser using the four-terminal pair probe configuration described by the Keysight Technologies impedance measurement handbook section 3.1.4. The initial set of measurements was taken at 200 frequencies within the 20Hz-20MHz range, using a linear frequency sweep. For subsequent measurements the scheme was changed to use 1000 frequencies in a logarithmic sweep to better represent the response at lower frequencies. Measurements about 10MHz were found to be significantly affected by the measurement probes in use. These were discarded."
description: No novel techniques have been used in the acquisition or processing of the data.

title: Dataset relating to "Cementitious materials data for aerial additive building manufacturing", phase one, 2017

description: This dataset contains test data relating to the Aerial Additive Building Manufacturing project's initial phase of investigations into cementitious pastes and mortar mixes. A series of mixes are formulated using CEM1, fly-ash, silica fume, polyol resin, limex, building sand and plasticiser in varying quantities and the mixes are tested in terms of mechanical strength, rheology, calorimetry, microstructure and creep. Data collected from the tests are stored in Microsoft Excel format. Mixes are also evaluated qualitatively (by inspection) and quantitatively (using power requirements) by the ease in which they pass through a small lightweight syringe-based automated deposition device (workability) and the buildability of the mixes (the ability to support their own weight and the weight of subsequently deposited layers) is assessed by inspection.
description: Data was collected from the software of the various testing devices and imported into Microsoft Excel.

Power data and qualitative data concerning buildability were collected by inspection and written recording.

title: Dataset for "Single-mode solarization-free hollow-core fiber for ultraviolet pulse delivery"

description: The dataset includes all raw data and files to regenerate all figures in the paper, where we report novel anti-resonant silica hollow-core fibers (AR-HCFs) for solarization-free ultraviolet (UV) pulse transmission. We present a single fiber that guides over a part of the UV-C and the whole of the UV-A spectral regions and a second AR-HCF used for delivery of 17 nanosecond laser pulses at 266 nm at 30 kHz repetition rate. By direct comparison we demonstrate that the single-mode AR-HCF significantly outperforms commercially-available high-OH and solarization-resistant silica multimode fibers for pulsed light delivery in this spectral range. MATLAB scripts are also found which filter the straylight background in the raw data measured by UV spectrometer and generate the all attenuation curves in the paper.
description: In the cutback measurement, the fiber is rewound in loops in 1 m diameter. Ando AQ6315A and Ocean spectrometer USB4000 are used to measure the transmitted power before and after cut at visible and UV wavelengths respectively.

The measurement of 266 nm laser transmitted through hollow-core fiber is by using power meter to directly measure the laser power at the output of fiber. Recording the reading usually takes a few seconds and the average of minimum and maximum power during this period of time is recognized as the transmitted power.

The fluorescence is measured by using a short piece of multimode (approx. 15cm) fiber to sample light into Ocean spectrometer.
description: MATLAB code is to process the raw data measured by Ocean spectrometer. The main purpose of code is to remove the significant background in the spectra due to the straylight. The measured spectral intensities measured before and after cut are input file to be read by MATLAB. Integration time and fiber lengths are needed to generate the corresponding attenuation curves. In the operation, the UV bandedge are required to manually identify on the screen by hand. By clicking the cursor, the X position will be automatically recorded and the local wavelength be recognized as the edge of band. The clicking point should not be at the sharp transitions of band but offset.
