  • Raman spectra of possible impurities in hydrogen relevant to ISO 14687:2025

    Description:
    The dataset contains a comprehensive list of normalized Raman spectra relevant to ISO 14687:2025. Additionally, the Raman spectrum of hydrogen contaminated by nitrogen at a pressure of 35 MPa is presented. , The 31 different substances were chosen due to their relevance to ISO 14687:2025. Acquisitions took place at different locations in Germany with a prototype Raman setup, which utilizes a 450 nm laser diode operating with a constant power of 3.5 W. As different sensors were used over the collection phase and the system was recalibrated after changes, the spectra differ in bandwidth as well as in resolution. In addition to the spectra of possible constituents in hydrogen, an exemplary spectrum of hydrogen with approximately 18.6 mmol/mol of nitrogen at a pressure of 35 MPa is shown., For safety reasons and to protect the components of the spectrometer, some gases were diluted either with argon or nitrogen. To increase the signal intensity of diluted samples, the duration of the measurement and/or pressure was varied. This metadata of the spectra contains: The pressure of the gas during acquisition p and the duration of the measurement t. If the sample was diluted, the type of carrier gas and amount of substance (n) in the carrier gas is indicated, as well., When using our dataset in your research, please refer to it as follows: , and C. R. Günther, L. Appold, P. Adam, A. Stratmann, D. Naglav-Hansen, A. Ostendorf & C. Esen, 2026, Raman spectra of possible impurities in hydrogen relevant to ISO 14687:2025, 2026, ReSeeD Research Data Repository, Research Data Services (RDS) of the Ruhr University Bochum.

  • Validation of the German Version of the Problematic Media Use Measure (PMUM-short form) and its relation to child and parental mental health

    Description:
    Problematic media use in children and adolescents has been linked to various mental health concerns. Given the increasing prevalence of media use among German children, it is crucial to have a valid tool to assess problematic media use. The present study validated the 9-item short form of the problematic media use measure (Domoff et al., 2019) in a German sample of N = 240 parents of 4-16-year-old children and explored its relationship with child and parental mental health. Parents completed questionnaires on their child’s problematic media use, psychosocial functioning, their own mental health and media use online. The German version of the PMUM-SF demonstrated high internal consistency, and good convergent and incremental validity. Problematic media use was significantly associated with age and with child functioning such as externalizing and internalizing problems. Furthermore, parental media use and parental stress and depression were positively correlated with child problematic media use. The study thus supports the use of the German version of the PMUM-SF as a measure of problematic media use in children ages 4 through 16 years old.

  • Distributed Fiber Optic Sensing (DFOS) Measurements of the 2025 M8.8 Kamchatka Earthquake in Brabant, the Netherlands

    Description:
    This dataset is part of a Distributed Fiber Optic Strain Sensing (DFOS) study along a dark fiber for monitoring purposes conducted on an optical fiber link between Boxmeer and Deurne in the Netherlands. The work investigates the application of DFOS using existing dark fiber infrastructure from telecommunication companies to capture strain variations along tens of kilometers with high spatial and temporal resolution. The experiment covered the time period from 2025-06-25 08:19:32 UTC to 2025-08-11 11:56:03 UTC. This data set contains the recordings covering the arrival of seismic waves from the 2025 M8.8 Kamchatka earthquake between 2025-07-29 23:30:01 UTC to 2025-07-30 01:15:46 UTC. Recordings with the QuantX-system contain the following settings: gauge length of 20 m, channel spacing of 2 m, and a sampling rate of 250 Hz. The dark fiber has a length of nearly 36 km, leading to a total of 18,100 channels in each file. File naming follows the start timestamp in BTS. The 26 geo-referenced channel locations from tap tests and/or locatable noise sources are contained in this data set as well.

  • Earthquake Catalog and Continuous Waveforms from a Two-Week Distributed Acoustic Sensing experiment on Kefalonia Island, Greece.

    Description:
    The dataset contains continuous waveforms from a two-week Distributed Acoustic Sensing (DAS) experiment and the resulting catalog(s). The DAS data were recorded along a ~15 km-long dark telecom optical fiber connecting the villages of Antipata (Kefalonia) and Stavros (Ithaki), Greece. Continuous waveforms cover the period from 1 August 2024, 23:00 UTC to 15 August 2024, 23:00 UTC, with a short data gap between 09:14 and 09:48 UTC on 6 August 2024 due to an archiving interruption. File names correspond to UTC time + 1 hour, following the default system convention. Data acquisition was performed using a QuantX OptaSense interrogator with a ping rate of 5000 Hz, and subsequently decimated by a factor of 20 to a final sampling rate of 250 Hz. The system configuration used a gauge length of 10 m and a channel spacing of 2.04 m, resulting in a total of 7,750 channels. Waveform data are stored in 30-second segments and in the default instrument unit (optical phase shift). Additionally, we include the channel list after removing loops. and The DOWNLOAD ALL button provides a bash script that downloads all files in this dataset using a sequence of 'curl' commands. You may edit the script to suit your needs—for example, by removing or commenting out 'curl' lines corresponding to files or time intervals you do not wish to download.
