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.

Research Data supporting the publication "Robust cytoplasmic partitioning by solving a cytoskeletal instability”
(Technische Universität Dresden, 2025-10-23) Rinaldin, Melissa; Kickuth, Alison; Xu, Yitong; Brugués, Jan
This dataset contains fluorescence imaging raw data and Python and ImageJ analysis scripts that were produced during the study of microtubule asters in frog egg extract and zebrafish and fruit fly embryos. The fluorescence images and time sequences consist of (1) investigations of stability and patterning phenotypes by labelling microtubules, DNA, lipids, and mitochondria, (2) study of microtubule density and polymerisation speed with imaging of EB1 comets, and (3) study of microtubule turnover with tubulin speckles and FRAP. The Research Data are organised by Figure and Extended Data Figure numbers of the manuscript, with detailed descriptions provided in the publication.

Data Underpinning: Disorder-driven magnetic duality in the spin-½ system ktenasite, Cu₂.₇Zn₂.₃(SO₄)₂(OH)₆·6H₂O
(Technische Universität Dresden, 2025-10-17) Parui, Kaushick K.; Kulbakov, Anton A.; Gumeniuk, Roman; Carrillo-Aravena, Eduardo; Fernández-Díaz, María Teresa; Savvin, Stanislav; Korshunov, Artem; Granovsky, Sergey; Doert, Thomas; Inosov, Dmytro S.; Peets, Darren C.
Article abstract: Disorder in frustrated quantum systems can critically influence their magnetic ground states and drive exotic magnetic behavior. In the S = ½ system ktenasite, Cu₂.₇Zn₂.₃(SO₄)₂(OH)₆·6H₂O, we show that structural disorder drives an unexpected dimensional crossover and stabilizes a rare coexistence of distinct magnetic states. Neutron diffraction reveals significant Cu/Zn mixing at the Cu2 site, which tunes the Cu²⁺ sublattice from a two-dimensional scalene-distorted triangular lattice into a one-dimensional spin-chain network. Magnetic susceptibility, neutron diffraction, ac susceptibility, and specific heat measurements collectively indicate magnetic duality: a coexistence of incommensurate long-range magnetic order below TN = 4 K and a cluster spin-glass state with Tf = 3.28 K at f = 10 Hz. Our findings highlight ktenasite as a rare platform where structural disorder tunes the effective dimensionality and stabilizes coexisting ordered and glassy magnetic phases, offering a unique opportunity to explore the interplay of frustration, disorder, and dimensional crossover in quantum magnets.

Wildfire Exposure Online Map
(Technische Universität Dresden, 2025-10-08) Avouris, Evripidis
This interactive online map is accompanying the paper "Exposure of Settlements to Wildfires in a Transboundary Wildland-Urban-Interface Region in Central Europe" submitted to the NHESS journal, and was created to showcase exposure of settlements located within the boundaries of the Saxon/Bohemian Switzerland National Parks and the Conservation Areas of Saxon Switzerland and the Elbe Sandstone Mountains.

Supplementary Material to the PhD Thesis "Microscopic investigations of the fiber architecture of the human tympanic membrane"
(Technische Universität Dresden, 2025-10-07) Steuer, Svea
The Supplementary Material to the PhD Thesis "Microscopic investigations of the fiber architecture of the human tympanic membrane" contains volumetric raw data and additional videos and images which were created in the course of ex vivo investigations on human tympanic membranes with various optical imaging methods, i.e., polarization-sensitive optical coherence tomography (PS-OCT), second harmonic generation microscopy (SHG) and polarized light microscopy (PLM). Chapter 5 of the dissertation provides a detailed description of the investigations.

Supplemental data to "A mechanical ratchet drives unilateral cytokinesis"
(Technische Universität Dresden, 2025-10-01) Kickuth, Alison; Ursic, Urša; Staddon, Michael Feroli; Brugués, Jan
This dataset presents raw imaging data, quantitative measurements, and data visualisation code from zebrafish embryo experiments investigating contractile band dynamics during early cell division. The study examines the mechanical processes that drive unilateral cytokinesis, focusing on cytoskeletal organization across the cell cycle. High-resolution time-lapse microscopy and quantitative image analysis were used to capture and assess the cellular behaviours.
