  • Substrate characterization in a electrochemically derived Manganium-Cobaltium thin films

    Open Research Data
    open access

    Manganium-Cobaltium thin films were electrochemically deposited on a Ni foams subsrates in a one-step process at −1.1 V vs. Ag/AgCl in an aqueous solution of differently concentrated Mn(NO3)2·4H2O and Co(NO3)2·6H2O with the deposition time limited by charges of 60, 120, and 200 mC at 25 °C. The concentration ratios of Mn(NO3)2·4H2O to Co(NO3)2·6H2O...

  • XPS study of the YST ceramics

    Open Research Data
    open access

    Yttrium-doped strontium titanate  was prepared via conventional solid-state reaction method from Y2O3 (Sigma Aldrich, 99,9%), TiO2 (Sigma Aldrich, 99%) and SrCO3 (Sigma Aldrich,98%). For comparision, two other techniques were used for synthesis: Pechini and wet methods. Both kind of samples were measured, after and before reduction process (in a hydrogen)....

  • Parameters of land reference points in the Gdynia region and the Free-air anomaly grid of the South Baltic

    Open Research Data
    open access

    The data was registered during the campaign to verify the catalog value of the absolute point coordinates [point 5403 (POLREF-GORA DONAS)] of the national gravimetric control network. The data was recorded in two three-hour stationary measurement campaigns at the following points: Rozewie of the EUREF-POL network, Góra Donas POLREF, and mareograph points...

  • Reduction of the strontium titanate doped by Ytrium ceramics observed by X-ray photoemission spectroscopy method

    Open Research Data
    open access

    Ytrium-doped strontium titanate (YSTF) ceramics materials were manufactured by three various methods: 1) standard solid-state reaction method from Y2O3 (Sigma Aldrich, 99,9%), TiO2 (Sigma Aldrich, 99%) and SrCO3 (Sigma Aldrich,98%), 2) Pechini method, 3) wet method.

  • XPS data of deuterium and hydrogen grown boron-doped diamond

    Open Research Data
    open access

    The high-resolution C1s X-ray absorption spectra of BDD@H and BDD@D samples were measured using the facilities of the HE-SGM beamline (HE-SGM) at the BESSY II synchrotron radiation source of Helmholtz–Zentrum Berlin (HZB).[90] The measurements were carried out under ultra-high vacuum conditions: P ≈ 2×10−9 Torr at T = 300 K. The NEXAFS spectra were...

  • Mn-Co nanofilms on nickel foam measured by XPS mehod

    Open Research Data
    open access

    Manganium-Cobaltium based thin films were electrochemically deposited on a Ni based subsrates in a one-step process at −1.1 V vs. Ag/AgCl in an aqueous solution of differently concentrated Mn(NO3)2·4H2O and Co(NO3)2·6H2O with the deposition time limited by charges of 60, 120, and 200 mC at 25 °C. The concentration ratios of Mn(NO3)2·4H2O to Co(NO3)2·6H2O...

  • Surface modifcation of PMMA polymer detected by XPS

    Open Research Data
    open access

    In order to obtain the experimental specimens, four PMMA/PC61BM samples with the following  mass proportions were prepared: 10%, 20%, 30%, and 40%. In addition, as a reference, a PMMA sample without  PC61BM was prepared as well. For the fabrication process, PC61BM 99.5% (Solenne BV), chloroform HPLC  (Sigma Aldrich), and PMMA (commercially available...

  • AFM investigation of electrode fabricated by 3D printing

    Open Research Data
    open access - series: Scanning Probe Microscopies data

    3D printing, also known as additive manufacturing, has enjoyed great interest in recent years due to the versatility of this method of producing various shapes and details. Due to the possibility of precise control of the shape and composition of the printed elements, the discussed technique can be widely used in electrochemistry, including electrochemical...

  • Depth chemical profile in a CeIr3 sample

    Open Research Data
    open access

    The polycrystalline sample of CeIr3 used in the present studies was synthesized by arc-melting cerium (4N) and iridium (3N5) in an arc furnace on a water-cooled copper hearth using a tungsten electrode under a high purity argon atmosphere. A piece of zirconium was used as an oxygen getter. First, a button of Ir was prepared by arc-melting the iridium...

  • The luminescence study of Sc2(1–x)Ga2xO3:Cr3+/4+ coumpounds

    Open Research Data
    open access

    The growing interest in the use of near-infrared (NIR) radiation for spectroscopy, optical communication, and medical applications spanning both NIR-I (700–900 nm) and NIR-II (900–1700 nm) has driven the need for new NIR light sources. NIR phosphor-converted light-emitting diodes (pc-LEDs) are expected to replace traditional lamps mainly due to their...
