title: micro-XRCT data sets of a stone mastic asphalt drill core before and after a uniaxial compression test (sample 2): sample 2-2

description: This data set contains two micro X-ray Computed Tomography (micro-XRCT) data sets resulting from region of interest scans (diameter 58.32 mm, height 46.06 mm) of the center region of a stone mastic asphalt (SMA) drill core. The drill core was scanned with identical scanner settings before ("reconstructed_20200504_01.tar.gz") and after ("reconstructed_20201015_02.tar.gz") a uniaxial compression test.
&lt;br&gt;&lt;br&gt;
The sample had a diameter of 75.18 mm and a height of 71.88 mm before, respectively a diameter of 77.35 mm and a height of 68.74 mm after the compression test (measured by caliper). The asphalt mixture is a stone mastic asphalt with a nominal maximum aggregate size (NMAS) of 11 mm (SMA 11 S). It contains diabase aggregates and a 50/70 bitumen binder. The material is described in detail by &lt;a href="https://doi.org/10.1007/s11709-017-0407-9"&gt;Hu et al. (2017)&lt;/a&gt;.&lt;br&gt;&lt;br&gt;
The compression test was performed by controlling the load with the following procedure:&lt;br&gt;
&lt;ul&gt;
&lt;li&gt; Starting the measurement at a contact load of 10 N.&lt;/li&gt;
&lt;li&gt; Increasing the load to 500 N (stress around 0.11 N/mm&lt;sup&gt;2&lt;/sup&gt;) with a speed of 100 mm/min.&lt;/li&gt;
&lt;li&gt; Holding the load at 500 N (stress around 0.11 N/mm&lt;sup&gt;2&lt;/sup&gt;) for 600 s.&lt;/li&gt;
&lt;li&gt; Increasing the load by another 500 N (stress around 0.11 N/mm&lt;sup&gt;2&lt;/sup&gt;) with a speed of 100 mm/min and holding it for 600 s.&lt;/li&gt;
&lt;li&gt; Repeating the procedure of adding load in 500 N (stress around 0.11 N/mm&lt;sup&gt;2&lt;/sup&gt;) increments, until the maximum load of 5000 N (stress around 1.01 N/mm&lt;sup&gt;2&lt;/sup&gt;) is reached and held for 600 s.&lt;/li&gt;
&lt;/ul&gt;
During the test, time (s), distance (mm), and load (N) were logged at regular intervals and can be found in "2_2_compression_test_data.csv". A visualization of the test procedure is shown in "test_procedure.pdf".

title: Data for "Molten salt assisted synthesis of lignin derived porous carbon host for lithium-sulfur battery cathode"

description: Lithium-sulfur batteries offer high theoretical energy density and low cost. However, challenges such as the polysulfide shuttle effect and poor conductivity of sulfur have hindered their commercial application. In this work, porous nitrogen-doped carbon materials were synthesized from Kraft lignin using a molten salt method combined with urea and K₂CO₃ for pore generation in a single synthesis step. The use of a KCl/NaCl salt mixture as the reaction medium allowed for control over product morphology and increased yield by retaining volatiles. The effects of varying lignin/urea/K₂CO₃ mass ratios on the characteristics of the produced materials were analyzed. The carbon-based host materials were then combined with sulfur through chemical deposition and melt diffusion. The properties of the host materials and composites were characterized using TGA, SEM, EDS, BET, XPS, and Raman analyses. Electrochemical tests were conducted to study the impact on the electrochemical properties of the lithium-sulfur battery cathode. The analysis revealed that the controlled porosity and functionalization of the host materials  significantly influences the distribution and utilization of sulfur during electrochemical testing. By analyzing the effects of host material porosity and nitrogen doping, we improved the electrochemical properties of the cathode material. The best performing composite material exhibited a high initial discharge capacity 1407 mAh/g-S (83 % of the theoretical capacity of sulfur) and retained 825 mAh/g capacity (average fade of 0,105 % per cycle) and 98,7 %  coulombic efficiency after 200 cycles.  In addition, the material displayed good performance at commercially viable mass loading.

title: Digital rock physics and laboratory considerations on a high-porosity volcanic rock: micro-XRCT data sets

description: Reticulite (high-porosity volcanic rock) is a pyroclastic rock formed during intense Hawaiian fountaining events. The honeycombed network of bubbles is supported by glassy threads and forms a structure with a porosity of more than 80 %. It is an end-member for high-porosity materials with a high stiffness and brittleness. For this specific material, hydro-mechanical experiments are very difficult to perform. Therefore, digital rock physics plays an important role. Digital rock physics combines microtomographic imaging with advanced numerical simulations of effective material properties. It is used to complement laboratory investigations with the aim to gain a deeper understanding of relevant physical processes related to transport and effective mechanical properties. 
&lt;br&gt;
Two micro-XRCT data sets of two dry cubic reticulite samples under ambient conditions scanned at two different resolutions are provided ("Reticulite-01_AxMF01.rar" and "Reticulite_03_AxMF01.rar"). Further, for each of this data sets a subvolume with 400 x 400 x 400 voxels was extracted and segmented (binarized) into skeleton and pore space which are also provided ("Segmented_subsamples.rar") and can directly be used for digital rock physics.
A third cubic reticulite sample was saturated with distilled water in three steps (500 microliters, 250 microliters and 250 microliters) with help of a pipette which was not removed during the CT scans. After each injection a scan was performed. The data sets are named according to the complete injected fluid volumes (“Reticulite-AxHP_wet_500ul.rar”, “Reticulite-AxHP_wet_750ul.rar” and “Reticulite-AxHP_wet_1ml.rar”).

title: micro-XRCT data set of an in-situ flow experiment with an X-ray transparent flow cell

description: Micro-XRCT data sets (projection and reconstructed images) of an in-situ experiment with an X-ray transparent flow cell. As a porous medium, a 3 mm cylindrical sandstone core from the County of Bentheim was investigated. The conceptual design of the cell was presented in &lt;a href="https://doi.org/10.1107/S1600577513026969"&gt;Fusseis et al. (2014)&lt;/a&gt; and offers the possibility to apply a confining and backpressure, and to inject a pore
fluid under X-ray radiation.&lt;br&gt;
Two scans were performed. The first scan was performed on the dry sample. The second scan was performed after the sample was saturated with 3M KI solution (3 mol potassium iodide per liter distilled water) with a constant flow of 100 µl/s against a backpressure of 0.28 MPa. To prevent hydrogen formation due to the X-rays, a flow of 0.5 µl/s was maintained against a backpressure of 0.28 MPa during the entire second scan. Both scans were performed under the same confining pressure of 0.6 MPa and with identical scan settings.

title: Cathedral of Beauvais

description: In 2001, a team of art historians and computer scientists from Columbia University traveled to France to create an accurate 3-D model of the Cathedral of Beauvais. They sought to analyze the building's structure and assist historic preservation efforts. Gale-force winds off the English channel constantly strain the cathedral's flying buttresses, which threaten to collapse. However, LiDAR scans made with a Cyrax 2500 enabled the team to accurately document the site and create models for structural analysis.
description: Upon its completion in 1247, the twice collapsed and rebuilt Cathedral of Saint-Pierre of Beauvais boasted the tallest choir ever built in Europe, and is still one of the most daring feats in Gothic architecture. Like many gothic cathedrals, the one in Beauvais was designed in the shape of a cross. The 47.5 meter tall nave is interrupted by a transept, which would have separated the pews from the choir and apse. The interior is lavishly decorated with stained glass windows, an intricately carved wooden altarpiece, and a functioning medieval clock.

title: Çatalhöyük - East Mound North Area 2013

description: This collection includes a mixed remote sensing dataset made of terrestrial laser scanning point clouds, point cloud comparison data, structure from motion-generated polygonal meshes, and related textures and metadata. It was recorded at the Neolithic site of Çatalhöyük, Turkey under the Çatalhöyük Digital Preservation Project carried out in 2012-2017 by scholars and students from the University of California Merced and Cardiff University. The historic series of North Area and South Area point clouds were documented by means of a Faro Focus S120 time of flight laser scanning during six consecutive field seasons (2012-2017), while the East Mound and West Mound landscape 3-D models were generated from low-altitude photos captured by an unmanned aerial vehicle (drone) in 2015.

The goal of the Çatalhöyük Digital Preservation Project was to capture the current state of the site to comply with UNESCO site management guidelines for conservation and to understand and quantitatively assess the deterioration of its mud-brick architecture through time via 3-D data comparison and geo spatial methods. The analyses of laser scanning data focus on the wall features of eight buildings of the North Area (B5, B48, B49, B55, B64, B82, B114, B119), which were chosen as priority by Ashley Lingle, the Head of Conservation at Çatalhöyük. Point clouds of wall features were segmented and aligned using the open source software CloudCompare. Pairs of perfectly aligned and identically segmented point clouds were then compared using the M3C2 method in CloudCompare to compute differences (standard deviation) and significant change. The differences among aligned and identical features represent the material loss occurred in those walls in 2012-2017. The point clouds were then analyzed in a GIS platform including environmental data logged in the North Area and vulnerability assessment made in situ by the Conservation Team.
description: Çatalhöyük (Turkish pronunciation: also Çatal Höyük and Çatal Hüyük; from Turkish Çatal 'fork' + höyük 'tumulus') was a very large Neolithic and Chalcolithic proto-city settlement in southern Anatolia, which existed from approximately 7100 BC to 5700 BC, and flourished around 7000 BC.[2] In July 2012, it was inscribed as a UNESCO World Heritage Site.

Çatalhöyük is located overlooking the Konya Plain, southeast of the present-day city of Konya (ancient Iconium) in Turkey, approximately 140 km (87 mi) from the twin-coned volcano of Mount Hasan. The eastern settlement forms a mound which would have risen about 20 m (66 ft) above the plain at the time of the latest Neolithic occupation. There is also a smaller settlement mound to the west and a Byzantine settlement a few hundred meters to the east. The prehistoric mound settlements were abandoned before the Bronze Age. A channel of the ÇarÅŸamba River once flowed between the two mounds, and the settlement was built on alluvial clay which may have been favorable for early agriculture.
