Fahmy, Karim Günther, Alix Bertheau, Rahel Pape, David 2024-09-30 The Excel file contains heat flow data from Schizophyllum commune cultures grown at 30 °C at different glucose concentrations. Measurements were carried out with a TAMIII instrument (TA-Waters) using 4 mL ampoules filled with 2 mL of growth medium.The heat flow curves show an oxidative phase followed by a fermentative phase at high glucose concentration. The two corresponding peaks can be evaluated indepndently by chosing the appropriate heat range. (The publication DOI:10.14278/rodare.3152 contains these data with the according analysis results). The Excel file serves also as a template for users to paste in their raw data. The format must not be changed for successful upload in METABOLATOR (DOI: 10.14278/rodare.3150).

Hoang, Duong Huu Pereira, Lucas Kupka, Nathalie Tolosana Delgado, Raimon Frenzel, Max Rudolph, Martin Gutzmer, Jens 2020-10-08 This particle dataset was used for demonstrating the particle-tracking method presented in the paper "Computing single-particle flotation kinetics using automated mineralogy data and machine learning", submitted to Minerals Engineering in 08/10/2020, by Lucas Pereira, Max Frenzel, Duong Huu Hoang, Raimon Tolosana-Delgado, Martin Rudolph, Jens Gutzmer from the Helmholtz Institute Freiberg for Resource Technology. This data belongs to the flotation tests performed by Duong Huu Hoang, and presented in: Hoang, D.H., Kupka, N., Peuker, U.A., Rudolph, M., 2018. Flotation study of fine grained carbonaceous sedimentary apatite ore – Challenges in process mineralogy and impact of hydrodynamics. Miner. Eng. 121, 196–204. https://doi.org/10.1016/j.mineng.2018.03.021 For this study, phosphate rock samples from the Lao Cai province, Vietnam, were provided by the Vietnam Apatite Limited Company. The objective of the flotation experiments was to determine the best way to efficiently separate fluorapatite from dolomite, calcite and silicates. After grinding for 8 minutes in a laboratory ball mill to assure a d90 of 67 µm, batch flotation tests were performed in a flotation cell built at the TU Bergakademie Freiberg. Corn starch ((C6H10O5)n) gelatinized with sodium hydroxide (NaOH) was used in combination with sodium silicate (Na2SiO3) to depress gangue minerals. The latter also acts as a fine particle dispersant. Solution pH was kept at 10 using the modifier sodium carbonate (Na2CO3), which can also be regarded as a depressant. Berol 2015 was used as the collector. Four concentrate fractions were collected after 0.75 min (CA), 1.50 min (CB), 3.00 min (CC), and 6.00 min (CD). In addition, a final tailings sample was collected (TD). Five replicates of the test were done to ensure reproducibility and produce enough sample mass for detailed characterization. All samples, including the feed, were wet sieved into four size fractions (-20 µm, +20 to -32 µm, +32 to -50 µm, and +50 µm) before characterization by MLA at the Helmholtz Institute Freiberg for Resource Technology. Samples were analyzed on a FEI Quanta 650F scanning electron microscope equipped with two Bruker Quantax X-Flash 5030 EDX detectors. The SEM was operated at 25 kV overall electron beam accelerating voltage and Extended BSE Liberation Analysis measurement mode. MLA results were validated with ICP-OES chemical assays. Particles from the flotation product samples (concentrate and tailings) are in the Traindata.csv file, while particles from the feed sample are in the FeedData.csv file.

Thiele, Samuel Thomas Kirsch, Moritz Madriz Diaz, Yuleika Carolina Gloaguen, Richard 2024-05-15 This hyperspectral drillcore dataset (shed) contains 10 drill holes, totalling 413 boxes that cumulatively contain 2845 meters of scanned cores. Hyperspectral data is stored in the widely used ENVI format (.dat and associated .hdr files), which can be opened using e.g., napari-hippo (GUI) and hylite (python). The whole directory structure is compatible with hycore, for easier out-of-core processing and visualisation. These hyperspectral data and associated visualisations can also be viewed interactively here. These cores intersect stratigraphic units of the Lower Carboniferous Irish Midlands, including the Lucan Formation (Upper Dark Limestones), the Feltrim Formation (Boulder Conglomerate), the Slane Castle Formation (Argillaceous Bioclastic Limestone), the Meath Formation (Shaley Pale Limestones unit), the Liscarton Formation (Mixed Beds unit), and Lower Paleozoic basement rocks. Scanning was conducted on cores such that a variety of lithology, sedimentary facies, proximity to mineralization, alteration intensity, and dolomitization intensity were sampled. These data were acquired as part of the Horizons Europe project Vector. Teck Ireland is acknowledged for providing access to core material and assisting with the hyperspectral scanning logistics. https://rodare.hzdr.de/record/2864 10.14278/rodare.2864 oai:rodare.hzdr.de:2864 eng url:https://www.hzdr.de/publications/Publ-39121 url:https://www.hzdr.de/publications/Publ-39108 doi:10.14278/rodare.2863 url:https://rodare.hzdr.de/communities/energy url:https://rodare.hzdr.de/communities/hzdr url:https://rodare.hzdr.de/communities/rodare info:eu-repo/semantics/openAccess https://creativecommons.org/licenses/by/4.0/legalcode mineral deposits hyperspectral resources ireland sediment hosted Pb-Zn Collinstown Hyperspectral Drillcore Data info:eu-repo/semantics/other dataset

Missana, Tiziana Alonso, Ursula Mayordomo, Natalia García-Gutiérrez, Miguel 2023-01-29 Cadmium (Cd) is a toxic heavy metal with very low permissible exposure limits and is, thus, a very dangerous pollutant for the environment and public health and is considered by the World Health Organisation as one of the ten chemicals of major public concern. Adsorption onto solid phases and (co)precipitation processes are the most powerful mechanisms to retain pollutants and limit their migration; thus, the understanding of these processes is fundamental for assessing the risks of their presence in the environment. In this study, the immobilisation of Cd by smectite clay has been investigated by batch sorption tests, and the experimental data were interpreted with a thermodynamic model, including cation exchange and surface complexation processes. The model can describe the adsorption of Cd in smectite under a wide range of experimental conditions (pH, ionic strength, and Cd concentration). Under the conditions analysed in this study, the precipitation of otavite (CdCO₃) is shown to have a limited contribution to Cd immobilisation. https://rodare.hzdr.de/record/2136 10.14278/rodare.2136 oai:rodare.hzdr.de:2136 doi:10.3390/toxics11020130 url:https://www.hzdr.de/publications/Publ-36480 url:https://www.hzdr.de/publications/Publ-36478 doi:10.14278/rodare.2125 url:https://rodare.hzdr.de/communities/energy url:https://rodare.hzdr.de/communities/rodare info:eu-repo/semantics/openAccess https://creativecommons.org/licenses/by/4.0/legalcode contaminants cadmium adsorption surface complexation modelling cation exchange risk assessment clays geochemical barrier otavite Data publication: Analysis of Cadmium Retention Mechanisms by a Smectite Clay in the Presence of Carbonates info:eu-repo/semantics/other dataset

Kipping, Ragna Hampel, Uwe 2020-04-02 For the investigation of bubble column hydrodynamics an experimental study using ultrafast electron beam X-ray tomography (UFXCT) has been carried out. Local hydrodynamic parameters were measured in a DN100 bubble column using two types of capillary gas sparger, which are named as 'Type A' and 'Type B' . Nitrogen is used as gas phase and deionized water as liquid phase. For Type B sparger additionally, experiments with sodium hydroxide of different concentrations are given. Experiments were carried out at two different measurement heights, which are located at 10 (L/D = 1) and 70 cm (L/D = 7) above the gas sparger An additional readme.txt file provides all required information and is necessary for the interpretation of the experimental data.

The developments are dedicated to the numerical simulation of multiphase flows, in particular to the multi-field two-fluid model (Euler-Euler method). Within the OpenFOAM library the multiphaseEulerFoam framework is used for this type of simulation. The addon contains a modified multiphaseEulerFoam named HZDRmultiphaseEulerFoam with the full support of the HZDR baseline model set for polydisperse bubbly flows according to Liao et al. (Chem Eng Sci, 2019, Vol. 202, 55-69). In addition a solver dedicated to a hybrid modelling approach (dispersed and resolved interfaces, Meller et al., Int J Numer Meth Fluids. 2021, Vol. 93, 748-773) named cipsaMultiphaseEulerFoam is provided with the addon. This solver has an interface to the multiphaseEulerFoam framework and utilizes all available interfacial models of it.

This describes the mineralogy of 204 thick-sections prepared from 49 drillholes sampled across 7 different locations and coregistered with VNIR-SWIR-MWIR-LWIR hyperspectral data. It is intended to help develop, test and benchmark methods for predicting mineralogy from hyperspectral data. The data are stored as hycore (https://github.com/samthiele/hycore) Shed directories for easy loading, although individual MLA sections and corresponding hyperspectral images are all in ENVI format (so can be loaded by any hyperspectral analysis code or software). MLA outputs are also stored in their original (high-resolution) form as indexed bitmaps. The AbundanceMapping.xlsx file can be used to translate these MLA class indices into modal mineral abundances. Finally, jupyter notebooks used to derive the benchmarks presented in the paper are also included, in the Code folder. These illustrate how the data can be loaded and manipulated using hycore and hklearn (https://github.com/samthiele/hklearn), and used to train machine learning models that predict modal mineralogy given hyperspectral data. https://rodare.hzdr.de/record/4582 10.14278/rodare.4582 oai:rodare.hzdr.de:4582 eng url:https://www.hzdr.de/publications/Publ-43223 doi:10.14278/rodare.4581 url:https://rodare.hzdr.de/communities/energy url:https://rodare.hzdr.de/communities/hzdr url:https://rodare.hzdr.de/communities/rodare info:eu-repo/semantics/openAccess https://creativecommons.org/licenses/by/4.0/legalcode hyperspectral mineralogy mineral liberation analysis machine learning benchmark geometallurgy Data for Upscaling mineralogy with hyperspectral data: a benchmark dataset and machine learning framework to enable hyperspectral geometallurgy info:eu-repo/semantics/other dataset

Kulenkampff, Johannes 2026-01-22 During the STROEFUN III R&D project, an experimental semi-dam seal structure made of MgO-concrete was built in the rock salt mining area of the Teutschenthal mine. The contact zone between host rock and concrete, as possible weak component of the barrier, is of major concern. Initial samples from the STROEFUN III project indicated small-scale zoning in the centimeter range with significantly increased porosity in some cases in the contact area, as well as joints with opening widths in the millimeter range. Within the framework of the follow-up project “FUNGUS”, µCT investigations of drill cores (diameter 50-100 mm) from different locations, mainly from the contact, were conducted to characterize this contact zone. The µCT images were taken using a Nikon XT H 225 scanner. The imaging parameters were typically: U = 220 kV, I = 150–180 µA, filter: 3 to 6 mm Cu. The filter is used to adjust the X-ray spectrum and optimize image contrast. Strong filtering causes hardening or monochromatization of the X-ray spectrum, which reduces the effect of absorption dispersion. Tomographic reconstruction was performed using the OEM software CTPro3D, including a beam hardening correction to compensate for the absorption dispersion, which depends on the X-ray spectrum and the thickness of the material being irradiated. The resolution of the measurement depends crucially on the distances between the source, object, and detector. The voxel size calculated from this can be regarded as an estimate of the resolution. Unfortunately, the tomograms showed ring artifacts, probably due to random detector errors. They were reduced by appropriate post-processing. This post-processing was conducted with Avizo (Fisher Scientific), applying • Ring Artefact Removal • Gray Scale Normalization • 3D-Non-local Means Filtering • Eventually rotation and resampling • Eventually Beam-Hardening-Correction or Background Correction These enhanced raw-images are included in this repository as 7z-compressed binary files, see FUNGUS_data.pdf for details.

Part of the data published here was used for prior works by Schabernack et al. (2025). Therefore, the the presented dataset has overlap withthe dataset published in Kulenkampff et al. (2024). This overlap is limited to the µCT data, and the PET data for analysis D_B and D_C. The data in this publication consists of: µCT data Core_D_after_dissolution_2496x2496x1615.raw: µCT of the inlet section of berea sandstone core D before dissolution as normalized graylevel data, voxel size = 10.032 µm. Format: 3D-array of uInt16, x=1:2496, y=1:2496, z=1:1615. Core_D_before_dissolution_2307x2329x1452_uint16.raw: µCT of the inlet section of berea sandstone core D after dissolution as normalized graylevel data, voxel size = 10.032 µm. Format: 3D-array of uInt16, x=1:2307, y=1:2329, z=1:1452. Positron emission tomography data All PET data is stored as three-dimensional binary arrays of floats, with a voxel size of 1.15 mm. Stored in [subset]_PET_raw.zip: Uncalibrated positron emission tomography time series (decay corrected). Each image consists of two files - a header file (.hv) and the binary image file (.v). The header file contains information on how to read the binary file, as well as additional information. Please note that not all of the metadata given in the header file (like timestamps, etc.) are generated automatically and not neccessarily accurate. Stored in [subset]_PET_err.zip: Relative errors of the PET_raw data, calculated from count rates using poisson statistics. A value of 1 equals 100% error. The volumes are cut to the ROI. The data structure is identical to [samplename]_PET_raw.zip. Stored in [subset]_PET_corrected.zip: Positron emission tomography time series, corrected for tracer activity and detector sensitivity fluctuations. Values are in in Bq/voxel. Voxels with relative errors above 100% are discarded. The volumes are cut to the ROI. The data structure is identical to [samplename]_PET_raw.zip. Flow field data stored in [subset]_flowfield.zip: Flow Direction_[X]x[Y]x[Z]x1_vec3_double.raw: Flow direction vectors as binary data of the shape [x,y,z,[3]], a three dimensional array of vectors which are stored as double (float64), voxel size = 1.15 mm.

Rox, Hannes Ränke, Fabian Zschach, Lis Geraldine Yang, Xuegeng Mutschke, Gerd Eckert, Kerstin Lasagni, Andrés Fabián Baumann, Robert 2025-01-28 Tuning the electrode surfaces for better bubble management is a promising approach to increase the efficiency of alkaline water electrolysis. Therefore, Direct Laser Writing was used to structure Nickel electrodes with a dual wetting surface. The applied pillar-like structure combines superhydrophilic behavior and strong spreading of the liquid across the electrode with hydrophobic bubble nucleation sites. In addition, the electrochemically active surface area is increased by a factor of 9. As a result, the overpotential has been significantly reduced, while the size of the detached bubble has increased. The present data set compares three different electrodes, a non-structured reference electrode and two laser structured electrodes with different depths of the structure, at applied current densities of j = -20, -50 and -100 mA/cm² in terms of electrode potential, detached bubble size and number of nucleation sites. As electrolyte 1 M KOH was used. All experiments were carried out under ambient conditions (T = 293 K,p = 1 bar). Description of Data.zip: An overview of all performed experiments is given in the file Summary.csv. The data is analyzed as described in the corresponding journal publication Dual wetting electrode surfaces for alkaline water electrolysis. Each data set is stored in a .hdf5-file, with the relevant metadata incorporated into the attributes assigned to the groups/datasets within the .hdf5-file. The data files are structured in groups as follows: Electrochemical Measurement Data Galvanostatic Measurement Data CV double-layer capacitance LSV onset potential Results Detected Bubbles Sideview Sideview Raw Images (only for SH2_LS_Pil_01.hdf5) With the exception of a single comprehensive data set comprising unprocessed images (SH2_LS_Pil_01.hdf5), the remaining raw images from all performed measurements can be made available upon request.

Grahn, Alexander Kliem, Sören 2020-09-25 The experiment ROCOM E2.3 represents a boron dilution event in a KONVOI-type pressurized lightwater reactor. It was conducted at room temperature with de-mineralized water without boric acid. Underborated water slugs were modelled by adding Ethanol in order to adjust a density difference of 1.22% with respect to the regular coolant inventory. At the beginning of the experiment, the slugs are enclosed between two valves in the cold legs of loops 1 and 2. The volume of the two water slugs accounts for 0.0576 m 3 (57.6 l) each and the slug fronts are located at 1.8 m upstream of the pressure vessel inlet nozzles. The experiment is started by opening the loop valves and running up the circulation pumps. The time dependency of the volumetric flow rates in all four coolant loops can be found in https://doi.org/10.1016/j.nucengdes.2020.110776. During the experiment, the mixing process was recorded by wire-mesh conductivity sensors at various positions within the coolant loops and the pressure vessel. The nomenclature of the data files as well as the format of the tables are described in the accompanying document DataDescription_ROCOME23.pdf. https://rodare.hzdr.de/record/528 10.14278/rodare.528 oai:rodare.hzdr.de:528 eng url:https://www.hzdr.de/publications/Publ-31562 doi:10.1016/j.nucengdes.2020.110776 url:https://www.hzdr.de/publications/Publ-30098 doi:10.14278/rodare.527 url:https://rodare.hzdr.de/communities/energy url:https://rodare.hzdr.de/communities/rodare info:eu-repo/semantics/openAccess https://creativecommons.org/licenses/by/4.0/legalcode boron dilution coolant mixing pressurized water reactor Experimental data of the ROCOME2.3 experiment info:eu-repo/semantics/other dataset

Techert, Gerda Kretzschmar, Jerome Worbs, Andreas Steudtner, Robin Bloß, Christoph Boelens, Peter Drobot, Björn Hübner, René Schönberger, Nora Pollmann, Katrin Lederer, Franziska 2026-01-14 Electronic waste and wastewater from mining, industry, etc. are valuable secondary sources of strategic high-tech metals like rare earth elements (REEs). Due to low concentrations of REEs, their recovery is challenging. Current separation processes have high energy consumption and use large amounts of toxic or expensive reagents, resulting in contaminated water and its costly reprocessing. Biomolecules, as environmentally friendly alternatives, are able to overcome these economic and ecological issues. Metal-binding peptides are convincing not only because of their high selectivity and stability under various conditions. In case of biobased production, they are also “renewable” resources and are neither toxic nor difficult to degrade at the process end. Here, we successfully utilized phage surface display (PSD) to screen for peptides with high affinity for REEs. The selected peptide GC22 (CEPDLWIDRFWC), identified by PSD in combination with next-generation sequencing, revealed the ability to precipitate lanthanide and yttrium ions from aqueous solutions in large quantities (> 60 %). It largely favors all REE ions over other commonly occurring metal ions in wastewater. The amorphous REE-GC22-precipitate is characterized by curled and spherical structures. Nuclear magnetic resonance spectroscopy revealed that in dimethyl sulfoxide Arg9 and Cys12 are most likely involved in metal binding. Reversibility of binding and thus regeneration of the peptide was demonstrated, enabling its potential use for multiple extraction cycles. GC22 thus offers a sustainable, cost-effective, and environmentally friendly alternative for future REE-recovery from low-REE-concentration wastewaters and e-waste leachates. https://rodare.hzdr.de/record/4374 10.14278/rodare.4374 oai:rodare.hzdr.de:4374 doi:10.17815/jlsrf-3-159 url:https://www.hzdr.de/publications/Publ-42690 url:https://www.hzdr.de/publications/Publ-42769 doi:10.14278/rodare.4373 url:https://rodare.hzdr.de/communities/energy url:https://rodare.hzdr.de/communities/fwi url:https://rodare.hzdr.de/communities/ibc url:https://rodare.hzdr.de/communities/rodare info:eu-repo/semantics/openAccess https://creativecommons.org/licenses/by/4.0/legalcode rare earth elements lanthanide recovery phage surface display peptides precipitation biomineralization recycling Research Data: Recovery of rare earth elements by peptide-induced Ln3+ precipitation info:eu-repo/semantics/other dataset

Lecrivain, Gregory Lecrivain, Gregory 2024-04-14 Source files and selected raw data related to the manuscript "Self-folding of two-dimensional thin templates into pyramidal micro-structures by a liquid drop - a numerical model" by Gregory Lecrivain, Helmholtz-Zentrum Dresden-Rossendorf, Germany, 2024. 1) folder "manuscript", This folder contains all text documents related to manuscript. Text and final figures are found in the directory. 2) folder "scripts" This folder contains python and bash scripts used to post process the raw data and prepare the figures.You will need to install some python3 libraries. Use the following command pip install pyquaternion matplotlib scipy intersect 3) folder "figures" This folder contain information on how to run the simulations related to the figure. More information in README file in each figure/figureX subfloder with X the figure number in the manuscript. 4) folder "src" This folder contains the all c++ files related to the source code. 4.1) Prior to compiling, you should have gcc(7.3.0), openmpi(2.1.2), make(4.3), cmake(3.20.2), python(3.8.0), blas(3.8.0), lapack(3.8.0), boost(1.78.0), and git(2.30.1) available on your machine. The version number in the parenthesis corresponds to the one I used on the local HPC available at my institution. In my case, I type "module load gcc/7.3.0 openmpi/2.1.2 make/4.3 cmake/3.20.2 python/3.8.0 blas/3.8.0 lapack/3.8.0 boost/1.78.0 git/2.30.1". 4.2) To compile the libraries, open a terminal, cd to the src directory and type "make libs". All outputs will placed in the folder $HOME/local. The libraries' tarballs needed to compile the code are placed in the Libs directory. 4.3) I have manually installed paraview 5.9.1 in $HOME/Paraview/ParaView-5.9.1-MPI-Linux-Python3.8-64bit/. pvpython is used to export txt data (hinge, drop and three-phase contact line) to vtk format. 4.4) Open your ~/.bashrc file and add the following lines. export IGL_NUM_THREADS=1 export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$HOME/local/libconfig-1.7.3/lib export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$HOME/local/gmp-6.2.1/lib export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$HOME/local/mpfr-4.1.0/lib export PATH=$PATH:$HOME/Documents/microorigami/src #(or whereever, your chosen parent directory is) export PATH=$PATH:$HOME/Documents/microorigami/scripts #(or whereever, your chosen parent directory is) export PATH=$PATH:$HOME/Documents/microorigami/paraview/bin #(or whatever path you used) 4.5) open a new terminal, cd to the src directory and type "make check_library_path". The terminal should return "library path to libconfig is correct" "library path to gmp is correct" "library path to mpfr is correct" If that is the case, i.e. the paths are correctly set. To compile, type "make main post". Alternatively, one can speed up the installation by typing "make -j 4 main post", where 4 is the number of cpus I use. 4.6) Help is available in each header file (.h) in the form of doxygen comments. Type "make doxy". The folder html will appear under src. 4.7) Type "make clean" to clean the src folder 5) folders "caX_sideY_ecZ.zip" The zip files contains, where where X = 70 is the contact angle, Y = 5 the number of side panels and Z = 0.8, 1.6 and 2.4 the elasto-capillary number, are selected raw data related to Figure 10. All other raw data can be reproduced by following the commands in the README text file located in each figX folder, with X=1,2,...,13. After extraction, three folders will be created, namely wd/ca70/side5/ec0.8, wd/ca70/side5/ec1.6 and wd/ca70/side5/ec2.4, where wd is your working directory. To convert the data into human-readable format (txt, vtk, stl,...) type "source Utils.sh; ExportScript --verbose --submit" in the working directory wd on the hpc. The bash function ExportScript is located in "scripts/Utils.sh". https://rodare.hzdr.de/record/2803 10.14278/rodare.2803 oai:rodare.hzdr.de:2803 eng url:https://www.hzdr.de/publications/Publ-37084 url:https://www.hzdr.de/publications/Publ-37083 doi:10.14278/rodare.2325 url:https://rodare.hzdr.de/communities/energy url:https://rodare.hzdr.de/communities/fwd url:https://rodare.hzdr.de/communities/rodare info:eu-repo/semantics/openAccess https://creativecommons.org/licenses/by/4.0/legalcode Micro-origami simulation drop encapsulation self-folding fluid-structure interaction Self-folding of two-dimensional thin templates into pyramidal micro-structures by a liquid drop - a numerical model info:eu-repo/semantics/other software

Missana, Tiziana Alonso, Ursula Mayordomo, Natalia García-Gutiérrez, Miguel 2023-01-29 Cadmium (Cd) is a toxic heavy metal with very low permissible exposure limits and is, thus, a very dangerous pollutant for the environment and public health and is considered by the World Health Organisation as one of the ten chemicals of major public concern. Adsorption onto solid phases and (co)precipitation processes are the most powerful mechanisms to retain pollutants and limit their migration; thus, the understanding of these processes is fundamental for assessing the risks of their presence in the environment. In this study, the immobilisation of Cd by smectite clay has been investigated by batch sorption tests, and the experimental data were interpreted with a thermodynamic model, including cation exchange and surface complexation processes. The model can describe the adsorption of Cd in smectite under a wide range of experimental conditions (pH, ionic strength, and Cd concentration).

Clarke, B. D. Renno, Axel Hamilton, David C. Gilbricht, S. Bachmann, Kai 2024-01-03 Data publication: The spatial association of accessory minerals with biotite in granitic rocks from the South Mountain Batholith, Nova Scotia, Canada D. Barrie Clarke; Axel D. Renno; David C. Hamilton; Sabine Gilbricht; Kai Bachmann Related to publication Geosphere (2022) 18 (1): 1–18; https://doi.org/10.1130/GES02339.1 We use mineral liberation analysis (MLA) to quantify the spatial association of 15,118 grains of accessory apatite, monazite, xenotime, and zircon with essential biotite, and clustered with themselves, in a peraluminous biotite granodiorite from the South Mountain Batholith in Nova Scotia (Canada). A random distribution of accessory minerals demands that the proportion of accessory minerals in contact with biotite is identical to the proportion of biotite in the rock, and the binary touching factor (percentage of accessory mineral touching biotite divided by modal proportion of biotite) would be ~1.00. Instead, the mean binary touching factors for the four accessory minerals in relation to biotite are: apatite (5.06 for 11,168 grains), monazite (4.68 for 857 grains), xenotime (4.36 for 217 grains), and zircon (5.05 for 2876 grains). Shared perimeter factors give similar values. Accessory mineral grains that straddle biotite grain boundaries are larger than completely locked, or completely liberated, accessory grains. Only apatite-monazite clusters are significantly more abundant than expected for random distribution. The high, and statistically significant, binary touching factors and shared perimeter factors suggest a strong physical or chemical control on their spatial association. We evaluate random collisions in magma (synneusis), heterogeneous nucleation processes, induced nucleation in passively enriched boundary layers, and induced nucleation in actively enriched boundary layers to explain the significant touching factors. All processes operate during the crystallization history of the magma, but induced nucleation in passively and actively enriched boundary layers are most likely to explain the strong spatial association of phosphate accessories and zircon with biotite. In addition, at least some of the apatite and zircon may also enter the granitic magma as inclusions in grains of Ostwald-ripened xenocrystic biotite. This data repository contains the complete set of the respective MLA – measurements (Reference) including the raw data and the data analysis.

The developments are dedicated to the numerical simulation of multiphase flows, in particular to the multi-field two-fluid model (Euler-Euler method). Within the OpenFOAM library the multiphaseEulerFoam framework is used for this type of simulation. The addon contains a modified multiphaseEulerFoam named HZDRmultiphaseEulerFoam with the full support of the HZDR baseline model set for polydisperse bubbly flows according to Liao et al. (Chem Eng Sci, 2019, Vol. 202, 55-69).

Couteau, Arthur Colombo, Marco Kriebitzsch, Sebastian Parekh, Jigar Schlegel, Fabian Draw, Mazen Evdokimov, Ilya Hänsch, Susann Khan, Harris Lehnigk, Ronald Meller, Richard Petelin, Gašper Tekavčič, Matej 2021-01-26 The HZDR multiphase addon contains additional code for the open-source CFD software OpenFOAM, released by The OpenFOAM Foundation. The developments are dedicated to the numerical simulation of multiphase flows, in particular to the multi-field two-fluid model (Euler-Euler method). Within the OpenFOAM library the multiphaseEulerFoam framework is used for this type of simulation. The addon contains a modified multiphaseEulerFoam named HZDRmultiphaseEulerFoam with the full support of the HZDR baseline model set for polydisperse bubbly flows according to Liao et al. (Chem Eng Sci, 2019, Vol. 202, 55-69). In addition a solver dedicated to a hybrid modelling approach (dispersed and resolved interfaces, Meller et al., Int J Numer Meth Fluids. 2020, 1-26) named cipsaMultiphaseEulerFoam is provided with the addon.
