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.

Data for: "PCL-based Drug Delivery System allows high antibiotic loading while maintaining cytocompatibility and antibacterial activity"
(Technische Universität Dresden, 2025-05-13) Guder, Celine; Hoffmann, Anja; Sterzenbach, Torsten
The present dataset encompasses images of PCL-based drug delivery systems subsequent to their fabrication. Moreover, it comprises raw data as well as processed data of UV/Vis measurements, which are employed to ascertain antibiotic concentrations. The dataset incorporates data from antimicrobial testing and the determination of minimal inhibitory concentrations via agar diffusion tests. Additionally, it encompasses data from assays of cellular toxicity with smooth muscle cells.

Variable total strain amplitude loading of 316L
(Technische Universität Bergakademie Freiberg, 2025-05-09) Szlosarek, Robert; Henkel, Sebastian; Nitzsche, Pia
This project investigates the behaviour of steel 316L under variable total strain amplitude loading, with a focus on understanding the material's response to complex loading conditions. Quasistatic tensile testing and fully reversed constant amplitude fatigue tests were conducted to characterize the material's properties. The variable amplitude tests were performed under total strain control, and the resulting stress-strain hysteresis loops were analysed to reveal the occurrence of mean stress after a drop in strain amplitude. Notably, the sign of the mean stress depends on the direction of strain transition between the tensile and compression domains. Furthermore, an ideal plastic material behaviour was observed after strain increase accompanied by mean stress. To facilitate further research and model development, the experimental data are published in combination with a research paper: Variable strain amplitude loading of steel 316L – experimental results and analytical modelling

Data for "Fractionalized fermionic multicriticality in anisotropic Kitaev spin-orbital liquids"
(Technische Universität Dresden, 2025-05-07) Fornoville, Max; Janssen, Lukas
The archive contains the data used to construct Figs. 1-3 of the paper "Fractionalized fermionic multicriticality in anisotropic Kitaev spin-orbital liquids" by M. Fornoville and L. Janssen [arXiv:2505.01493]. The work uses Majorana mean-field theory and renormalization group theory to study the low-temperature phase diagram of quantum Kitaev-Heisenberg spin-orbital models with XXZ anisotropy on the honeycomb lattice.
