The OPARA service was recently upgraded to a new technical platform. You are visiting the outdated OPARA website. Please use https://opara.zih.tu-dresden.de/ for new data submissions. Previously stored data will be migrated in near future and then the old version of OPARA will finally be shut down. Existing DOIs for data publications remain valid.

Epoxy-Based Particle Sample Preparation with Nano-Graphite as Spacer - RAW Data (Particle Sample Preparation)

To get good image segmentation results in tomographic analysis methods, particles has to be seperated from each other while embedding them into a matrix. Low X-ray absorbing nano-graphite below the voxel resolution of the system is mixed with the analysis particles to form a shell to avoid direct particle-particle contact. After mixing it with epoxy resin, the paste is sucked into a polymeric tube of 2 mm inner diameter. After hardening, the formed cylinder was scanned with an X-ray microscope (ZEISS Xradia Versa 510) with the following parameters: 80 keV, 7 W, 360°, 2001 projections, 1 s exposure time, 2 µm voxel size, binning 2. After scannning, the following filters were applied while reconstruction with ZEISS reconstructor: Beam Hardening Correction 0.05, Smoothing 0,7. Detailed overview of the parameters is summarized as screenshots within the repository.
