Dataset for Low-energy, ultrafast spin reorientation at competing hybrid interfaces with tunable operating temperature
No full textInformation can be stored in magnetic materials by encoding with the direction of the magnetic moment of elements. A figure of merit for these systems is the energy needed to change the information – rewrite the storage by changing the magnetic moment. Organic molecules offer a playground to manipulate spin order, with metallo-molecular interfaces being a promising direction for sustainable devices. Here, we demonstrate a spin reorientation transition in molecular interfaces of high magnetisation 3d ferromagnetic films due to a competition between a perpendicular magnetic anisotropy (PMA) induced by a heavy metal that dominates at high temperatures, and an in-plane anisotropy generated by molecular coupling at low temperatures. The transition can be tuned around room temperature by varying the ferromagnet thickness (1.4 to 1.9 nm) or the choice of molecular overlayer, with the organic molecules being C60, hydrogen and metal (Cu, Co) phthalocyanines. Near the transition temperature, the magnetisation easy axis can be switched with a small energy input, either electrically with a current density of 〖10〗^5 A/〖cm〗^2, or optically by a fs laser pulse of fluence as low as 0.12 mJ/〖cm〗^2, suggesting heat assisted technology applications. Magnetic dichroism measurements point toward a phase transition at the organic interface being responsible for the spin reorientation transition
Data associated with 'Injection Volume Is a Better Predictor of Stiffness Restoration Than Injection Force in an In Vitro Study of Nucleus Augmentation of the Intervertebral Disc'
No full textData from a biomechanical study of spinal nucleus augmentation with a self-assembling hydrogel. The biomechanical data was acquired during in vitro testing of bovine tail specimens in a native, artificially degenerated, and treated states
Supplementary Material - Hydrodynamic Interactions Between Pairs of Sedimenting Semi-Flexible Brownian Fibres
No full textThe results for a pair of sedimenting semiflexible fibres with initially both horizontal and vertical configurations have been reported here. These include the rho-value, cos2 (tetha), the nondimensional interaction velocity and rate of rotation, sedimentation velocity, eigenvalues of gyration matrix. In addtion to that, the results of the Phi changes and the ratio of maximum deflection (A) to the length of the fibre (l) for a single sedimenting fibre has been put in the dataset
Soil physical, chemical and hydrological data from agroforestry plots at Spen Farm, Yorks, UK, 2022-23
No full textSoil and forest floor litter data sampled between 2022 and 2023 at the Spen Farm High Value Timber Agroforestry plots. Trees at the site were planted in 1988, and sampled areas include continuous woodland blocks of three species - sycamore, wild cherry and hazel, along with adjacent arable control blocks. Each block is replicated four times. Soil properties are measured between 0 and 50cm at 10cm intervals, and mineral soil measurements are supplemented by measurements of the forest floor L and combined F and H horizons. The dataset also includes measurements of saturated hydraulic conductivity taken at the soil surface
Soil, infiltration and above-ground biomass data for agroforestry at Shillingford, UK, 2023
No full textSoil, above ground biomass and infiltration data collected from agroforestry fields and an adjacent, treeless control field at Shillingford, Devon in May 2023. Agroforestry tree rows were planted at 12m (2002) and 24m (2012) spacing. Sampling was undertaken in four locations relative to tree rows – in line with tree rows at center of row and 1m from nearest tree, perpendicular to tree rows and 1m from nearest tree (0.5m from alley edge in tree row), perpendicular to tree rows and 2m from nearest treee (0.5m from alley edge in alley) and in centre of alley. Soil was sampled at three intervals between 0 and 50cm depth. Tree height and DBH data were measured on five trees each selected at random from two tree rows in each agroforestry field. Infiltration data was collected at the same sample locations as soil data
Living with the Dead: Remembrance and Family History in Britain
Full text linkThis project examined how families remember the dead and pass on their histories. It involved collaboration with a group of family historians as well as archival research into libraries and archives around Britain. The project was AHRC-funded, and has also involved work with libraries, museums, artists and charities. The key publication from the project is a book published with OUP, "Living with the Dead: Memories, Histories, and the Stories Families Tell in Modern Britain
Dataset associated with 'Reactive fluid-like ferroelectrics: a gateway to the next generation of ferroelectric liquid crystalline polymer networks'
No full textThis dataset contains the data associated with the article titled 'Reactive fluid-like ferroelectrics: a gateway to the next generation of ferroelectric liquid crystalline polymer networks', published in Small. The data is provided either as raw data files or the files used to plot figures in the relevant article. Data is focused primarily on structural characterisation and material properties of the monomers synthesised in the article, whilst also extending to the data obtained in the polymer stabilisation studies conducted in the relevant article

Bubble population growth and gas release from packed beds of AW500 ion exchange pellets - Dataset.
No full textData relating to study exploring the phenomenon of in situ generated gas retention within densely packed cylindrical ion-exchange pellets. Initially, discrete element method (DEM) simulations were used to identify pertinent contact packing parameters, rigorously validated through packing experiments. Calibrated values for dynamic and static friction, and the coefficient of restitution were found in ranges of 0.8–1.0, 0–0.2, and 0–0.2, respectively, with the importance of dynamic friction highlighted. The DEM validation process achieved a packing fraction that exhibited < 4 % deviation from experimental data, with some cylinder alignment observed near the column base. Additionally, laboratory-scale gas generation tests were conducted to replicate the retention of hydrogen within densely packed beds, achieved through the decomposition of hydrogen peroxide. X-ray computed tomography was then used to quantify bubble population size and growth within the beds
Finite element model of a rabbit skull
Full text linkThe dataset contains a finite element model of a rabbit skull, which contains hard (separate bones and teeth) and soft tissues (sutures and periodontal ligament). Files are provided to simulate a maximum incisor bite when considering a range of material properties for each bone in the skull. The files include: 1) a high resolution (~19million elements) mesh of the skull compatible with ANSYS; 2) input files for muscle loading, constraints and material properties; 3) a input file to run a range of simulations (compatible with ANSYS) which varies the material properties for each bone to use either i) bone-specific isotropic elastic modulus when measured in a particular orthotropic direction, ii) average isotropic elastic modulus when measured in a particular orthotropic direction, iii) bone specific orthotropic material properties with varying magnitudes of shear modulus. The material properties are taken from Wang et al (2024) (DOI: 10.1371/journal.pone.0298621). The files provided enables the user to output an image of the strain in the skull, along with averaged strain along a prescribed path through the skull (4 paths are included as a demonstration). Input files can be altered to alternative bone material properties and muscle forces
