Dataverse UA is a national research data repository designed to support open science and implement the FAIR principles (Findable, Accessible, Interoperable, Reusable) in Ukraine. Its mission is to ensure long-term preservation, publication, and reuse of research outputs in standardized formats. The platform enables researchers, educators, graduate students, and institutions to store datasets, metadata, supporting documents, and code — all with persistent identifiers (DOIs), Creative Commons licenses, and ORCID integration. Dataverse UA supports both Ukrainian and English, allows the creation of thematic collections by discipline or institution, and complies with the standards of the National Academy of Sciences of Ukraine and international best practices. It is a tool for enhancing transparency, reliability, and reproducibility in research, while connecting Ukrainian science to global open data ecosystems.

Tkach, Vira; O.Y. Khyzhun; N.M. Denysіuk; Kopylova Kateryna Ihorivna, 2026, "Analysis of Ag2HgSnS4 Compound by X-ray photoelectron spectroscopy", https://doi.org/10.48788/DVUA/U6JWSR, DataverseUA, V1
This dataset contains survey, high-resolution core-level, and valence-band X-ray photoelectron spectroscopy (XPS) data obtained from the pristine surface of an Ag2HgSnS4 single crystal grown by the Bridgman–Stockbarger technique. The deposited files cover the Ag 3d, Hg 4f, Sn 3d,...
