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 You are visiting the outdated OPARA website.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/ to visit the current OPARA website. 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.

Verwendete Forschungsinstrumentenano-CT (ZEISS, Xradia 810 ULTRA)
Verwendete ForschungsinstrumenteFIB-SEM + EDXS (FEI, Helios NanoLab 660, dual beam)
Zugrundeliegende ForschungsobjekteSubstance: micron-sized particle samples of talcum (Giessereitechnik Wystrach GmbH & Co. KG, Germany) and saxolite (type Saolith 2 extra, Erzgebirgische Kalkwerke GmbH GEOMIN, Germany), both 0.1 - 10 µm equivalent spherical diameter
KurzbeschreibungAll 3 data sets are sub-volumes (Field of View approx. 65 µm) of a total sample of a particle mixture of talc and saxolite fixed in a matrix by means of epoxy resin and spacer particles (nanometre-sized carbon black particles, 150 nm equivalent spherical diameter). The primary analysis was carried out using nano-CT. The reconstructed result data are stored in the form of TIF files as sectional images (folder "rotated"). In addition, a correlation was carried out by means of EDXS analytics, the chemical information of which was used to train a segmentation algorithm. Since EDXS analysis requires a planar surface, the sample was further processed using FIB. The divergence of the ion beam produces a slight angular deviation from the perpendicular of the nano-CT volume, which necessitated a rotation of the initial volume data (--> "rotated"). The correlated result data of the particle-discrete phase information are also stored ("rotated segmented").

  • Saxolite and Talcum [1]Open Access Icon
    Saxolite and Talcum are two materials with comparable X-ray attenuating properties and thus not to distinguish by direct comparison of image gray values.
