Research Data Repository of Saxon Universities

OPARA is the Open Access Repository and Archive for Research Data of Saxon Universities.


Researchers of Saxon Universities can either publish their research data on OPARA, or archive it here to comply with requirements of funding acencies and good scientic practice, without public access.

You can find the documentation of this service at the ZIH Data Compendium websites. If you need suppourt using OPARA please contact the Servicedesk of TU Dresden.

Please note: The OPARA service was recently upgraded to a new technical platform (this site). Previously stored data will not be available here immediately. It can be found at the still active old version of OPARA. These stock 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.

µCT images for soil fabric extraction
(Technische Universität Dresden, 2025-02-07) Bacic, Bozana
These data serve as the basis for the extraction and comparison of soil fabric in the case of two different natural sands and one mixture of glass beads prepared via sedimentation under water (UWFP). Furthermore, data for one coarse sand prepared using spoon slurry deposition (SSD) and via 45-degree sedimentation under water (45) are provided. These files support the publication: https://nbn-resolving.org/urn:nbn:de:bsz:14-qucosa2-945638.

Correlation Velocimetry inside a model of the human airways
(Technische Universität Bergakademie Freiberg, 2025-02-07) Bauer, Katrin; Kluwe, Moritz Niklas
The dataset corresponds to the publication "Deterministic periodic structures in a model of the human airways" by Kluwe et al. 2025. It contains raw data obtained from an optical setup used for point-wise velocity measurements using Correlation Velocimetry in a model of human airways. The recorded data consists of stereo audio files sampling the photo-electric response of two photodiodes to the passage of tracer particles. The time lag between both signals corresponds to the mean time of flight of ensembles of particles between both detectors. Using the known distance between the detectors (272 micrometers), the mean velocity of the tracer particles can be calculated. This dataset includes the raw data evaluated and discussed in the publication.

Adipic acid concentrations from biotransformation by rec. Pseudomonas taiwanensis
(Universität Leipzig, 2025-02-05) Franz, Alexander
The dataset belongs to a publication in Green Chemistry from 2023 (DOI: 10.1039/d3gc01105d). In the publication a two-step process is demonstrated, in which phenolic compounds are electrochemically hydrogenated and further converted to adipic acid by a biotransformation of recombinant Pseudomonas taiwanensis. The dataset shows the data from Fig. 3c and 4c in the publication. The two tables show the adipic acid concentration over time in the 500 mL-bubble column reactors, in which the biocatalyst was fed with the substrate solution.

Data for "Continuous order-to-order quantum phase transitions from fixed-point annihilation"
(Technische Universität Dresden, 2025-01-31) Moser, David J.; Janssen, Lukas
The archive contains the data used to construct Fig. 2, Fig. 3, and Fig. S5 of the manuscript "Continuous order-to-order quantum phase transitions from fixed-point annihilation" by David J. Moser and Lukas Janssen [arXiv:2412.06890]. The work exploits mean-field theory and renormalization group approaches to unveil several examples of continuous order-to-order quantum phase transitions from fixed-point annihilation.
