Imaging was conducted using an isotropic voxel-edge of 6.0 μm. Local Thickness was carried out in 3D using the “Volume Thickness Map” tool within Dragonfly software (cf. supplementary), allowing for the visualization and quantification of the spatial distribution and variability of tissue thickness.</p> <p>Imaging was conducted at the University of Southampton’s μ-VIS X-ray Imaging Centre ( https://muvis.org ) / 3D X-ray Histology facility, utilizing a customised μCT scanner optimisedfor intricate histological analyses(1), based on Nikon’s XTH225ST system (Nikon Metrology, UK). Operating parameters were set at 80 kVp / 86 μA (6.88 W), with a source-to-object distance of 37.5 mm and a source-to-detector distance of 937.4 mm, resulting in a magnification factor of 25x and an isotropic voxel-edge of 6.0 μm. Imaging acquisition involved the collection of 4001 projections using a 2850 x 2850 dexels detector, by averaging 4 frames per projection, with an exposure time of 500 ms per projection.</p> <p>Visualisation and analysis of the reconstructed dataset was done using Dragonfly software (Comet Technologies Canada Inc.; software accessible at http://www.theobjects.com/dragonfly). Assessment of Local Thickness was carried out in 3D using the “Volume Thickness Map” tool within Dragonfly software, following segmentation of the tissue layer. Local thickness analysis allowed for the visualization and quantification of the spatial distribution and variability of thickness within the tissue engineered oral epithelium (TEOE).</p> <p>Visual representation of local thickness histograms was employed to elucidate the distribution of thickness throughout the TEOE. These histograms effectively illustrate the number of voxels associated with specific cross-sectional thickness, offering both a graphical depiction of the variation in thickness across the tissue sample, and a quantitative measure of the average thickness of the specimen.</p> <p>It's worth noting, the volumetric and non-destructive nature of the technique enabled whole-block imaging, which proved crucial in addressing challenges arising from tissue sample shrinkage. This shrinkage, a consequence of dehydration during the fixation process, can occur in some cases and lead led to the specimen wrapping. While wrapping is not a common occurrence, this analysis method allowed for the evaluation of challenging-shaped specimens, such as the wrapped one presented in Figure 4. Unlike conventional 2D methods such as classical histology, which rely on the angle of slicing and encounter limitations when dealing with non-perfectly perpendicular slicing, μCT-based XRH enables analysis of all specimens, including those with complex shapes.</p> <p> </p>

Testing a Novel Geopolymer Binder as a Refractory Material for Rocket Plume Environments at SSC Project
<p>The project involved the development and testing of a new alumina-silicate based multi-purpose, cost-effective, &lsquo;green&rsquo; cementitious binder (geopolymer) capable of acting as a high performance refractory material with both a low ablation rate and a high early mechanical strength. This work was built upon previous research undertaken by the research team in the areas of geopolymer binders. Full scale and laboratory controlled tests were performed to compare geopolymer performance to currently available commercial products (e.g. Sentinel, Greencast). Geopolymer&rsquo;s thermal shock resistance properties were tested on eleven different fly ash stockpiles specimens from around the world. The geopolymer specimens were subjected to ASTM C-1100 (Standard Test Method for Ribbon Thermal Shock Testing of Refractory Materials). Samples were subjected to incremental 5-5-5-15-30 second flame exposure durations and to a 15 or 30 accumulated exposure, depending on the sample performance (e.g., if the plume became detached). Field test durations were limited to prevent excessive erosion of the test panels and subsequent plume detachment. Laboratory testing also demonstrated that geopolymer could withstand thermal shock and exposure to flame. Additionally, a computational model was created to determine the optimal chemical ratios for geopolymer to be exposed to elevated temperatures. Additionally, due to their excellent adhesion to pre-existing surfaces geopolymer binders were proven to be good candidates for use in repair of existing structures upon which they were applied and retrofitted; this was demonstrated and observed via tests conducted on repaired tested panels. Overall, the demonstration testing program revealed that the geopolymer products had equal or superior performance compared to commercial refractories currently used by NASA.</p>
