    Data associated with ‘The influence of the representation of collagen fibre organisation on the cartilage contact mechanics of the hip joint’

    No full text
    This dataset contains the results of a finite element (FE) hip model with subject-specific geometry and biphasic cartilage properties. Different levels of detail in the representation of fibre reinforcement were considered to evaluate the feasibility of simplifying the complex depth-dependent fibre pattern in the native hip joint. A FE model of a cadaveric hip with subject-specific geometry was constructed through micro-computed-tomography (µCT) imaging. The cartilage was assumed to be biphasic and fibre-reinforced with different levels of detail in the fibre representation. Simulations were performed for heel-strike, mid-stance and toe-off during walking and one-leg-stance over 1500 s. The data provided here comprises the results found for contract stress, fluid pressure, solid phase compressive stress, maximum and minimum Lagrangian strains for the models with different cartilage representations

    Dataset for 'A reproducible approach to the assembly of microcapillaries for double emulsion production'

    No full text
    This dataset contains measurements used in the paper, 'A reproducible approach to the assembly of microcapillaries for double emulsion production', published in the journal, Microfluidics and Nanofluidics (doi:10.1007/s10404-016-1806-2). Included are optical micrographs of commercially pre-pulled micropipettes which were used to assess the frequency and severity of tip misalignment caused by capillary pulling. A spreadsheet containing the completed analysis of these images is also included. This analysis underlies our argument that due to the regular defects in pulled micropipettes, a new reproducible assembly procedure for using glass capillaries in the production of double emulsions is needed. Microfluidic devices made using our new assembly procedure were evaluated by generating water-in-oil-in-water (W/O/W) and oil-in-water-in-oil (O/W/O) double emulsions - videos of which are available here. Finally, rheological measurements of the working fluids used are also included. If using the information from this dataset to aid your own work, the authors would kindly ask you to consider also citing the original journal article

    PEEK CFR-PEEK pin plate study dataset

    No full text
    Pin on plate studies to understand the influence of contact pressure, cross shear and counterface were undertaken with surface analysis measured prior to test and at completion. Mean wear factors for each condition were calculated at the completion of the study. This dataset includes the mean wear factor for each condition and the surface roughness measurements

    Data set associated with 'Magnetic Phases of Sputter Deposited Thin-Film Erbium'

    No full text
    We present a detailed structural and magnetic characterization of sputter deposited thin film erbium, determined by x-ray diffraction, transport measurements, magnetometry and neutron diffraction.This provides information on the onset and change of the magnetic state as a function of temperature and applied magnetic field. Many of the features of bulk material are reproduced, but of particular interest is the identification of a long-wavelength, c = 4=17, conical magnetic state not observed in any other thin film or bulk measurements. The data from the various techniques are combined to construct magnetic field, temperature (H; T){phase diagrams for the 200 nm-thick Er sample that serves as a foundation for future exploitation of this complex magnetic thin film system
