Comparing Membranes for Proton Exchange Membrane Water Electrolysis: Performance, Stability and Hydrogen Crossover
Full text linkThe supply of Nafion and Aquivion proton exchange membranes is currently severely constrained, prompting a search for alternatives. In this work, a new commercial proton exchange membrane (PFSA D170-U) was evaluated and compared with two other membranes: Nafion™ N117 and Aquivion® E98-15S. The performance, stability over 100 h, and H2 crossover characteristics of these three membranes were investigated in a flow cell electrolyser by testing each membrane type in triplicate using a fresh sample of membrane for each experimental run. At 60 °C, the three membranes showed an average performance of 1 A cm–2 at 2.0 V and an average degradation rate of 1.2 mV h–1 after stability tests for 100 h at a fixed current density of 1.0 A cm–2. The three membranes showed similar metrics, suggesting that PFSA D170-U is a promising proton exchange membrane alternative to Nafion and Aquivion membranes for research purposes. Additionally, the physical, morphological, structural, thermal and mechanical properties of the PFSA D170-U membrane were examined
Allt Lorgy river restoration scheme, Scotland, 2012-2024: geomorphological change, large wood and geomorphic units
No full textThe Allt Lorgy river restoration scheme, Scotland, has restored a 720 m long reach using a “working with natural processes” approach. This dataset includes geospatial data from a pre-restoration survey in 2012 and post-restoration surveys in 2014, 2016, 2019, 2022 and 2024 that have monitored the evolution of the river. These surveys include Digital Elevation Models (DEMs) and aerial imagery. These datasets have been used to generate maps of geomorphic change, segmented sediment budgets, geomorphic unit maps and the location of large wood
Zoopla Free Text Addresses to UPRN dataset
No full textOverview:
Zoopla plc is one of the UK’s major property listings services, founded in 2007. Their service includes domestic property listings for both rental and sales. UBDC has had a partnership with Zoopla since 2016. The Zoopla datasets contain information related to both rental and sale property listings in the UK from 2010 onwards. They cover various property characteristics including location, type, and size of property as well as other features along with the sale or rental price and the dates for which the listing was live. Open text fields may contain further unstructured information on property attributes and amenities
The method by which the research datasets are produced has changed over time so there are two series, both of which cover sales and rental listings:
• Generation 1: from the 1st of January 2013 to 31st December 2021
• Generation 2: from the 1st of October 2016 onwards
The fields available in each Generation are similar. Full details are provided in the tables below. The main differences between Generation 1 and Generation 2 are the inclusion in Generation 2 of geographic coordinates for listings (longitude, latitude) and the provision of additional information on changes in property features during the life of the listing.
Zoopla Freetext Addresses to UPRN dataset:
The dataset aims to enhance the Urban Big Data Centre's (UBDC) Zoopla dataset by resolving unstructured and malformed property addresses into standardized Unique Property Reference Numbers (UPRNs), making the data interoperable and hence adding value. The creation of the dataset involved leveraging a program named FLAP, which is designed to parse and match partial or misconstructed addresses to their correct UPRN. The dataset only contains entries regarding the 'sales' variant of the ubdc zoopla dataset
Access and restrictions:
Zoopla and Ordnance Survey's AddressBase Premium dataset licences are both required by researchers before access to this derived dataset is permitted. Researchers are required to provide evidence proving that they have these licences before the dataset would be supplied.

Towards a generic model for phosgene synthesis catalysis over activated carbon
No full textThe purpose of this data is to underpin a publication in ChemCatChem, the dataset includes spectroscopic information and characterisation data as well as processed data to produce the figures presented in this publicatio
Managing gardens for pollinators: Plant richness, abundance and origin seasonally influence flower visitor interactions regardless of the surrounding landscape
Full text linkThis data set underpins analysis within a research article. The data set encompasses plant-pollinator interactions recorded in private residential gardens in Glasgow, Scotland in 2023. Network and pollinator bipartite indices were then calculated for each network within these gardens. Alongside interaction data, garden environmental data is also presented
Revisiting the subharmonic route to acoustic chaos: broadband noise clearing via cavitation bubble synchronization
No full textThis dataset is to accompany a publication which demonstrated the synchronisation of bubbles. It contains a combination of experimental data (in the form of acoustic data and high-speed imaging data) of the bubble field produced by a tube transducer and numerically modelled data which was used to further investigate the underlying mechanism of this phenomenon
The impact of co-feeding carbon dioxide in Fischer-Tropsch-to-Olefin catalysis: an inelastic neutron scattering study
Full text linkData set obtained as part of post graduate studentship. The research investigates the influence of CO₂ on the formation and nature of the hydrocarbonaceous overlayer that develops during a promoted iron catalyst's conditioning phase
Fully Degradable, Transparent, and Flexible Photodetectors using ZnO Nanowires and PEDOT:PSS based Nanofibres
No full textThe dataset comprises files related to the electrical, optical, and morphological characterisation of the devices. It includes measurements and analysis results obtained through techniques such as I-V characterisation, UV-Vis spectroscopy and SEM imaging.
The dataset highlights a research article on flexible, transparent, and degradable UV photodetectors, using Zinc Oxide nanowires as the photosensitive element. The study investigates their performance in both aligned and random orientations between PEDOT:PSS/Ag nanowire-based fibrous electrodes, under varying UV light intensities, dynamic UV exposure, and on both flat and curved surfaces
