  • Influence of bio-polyols with different molecular weight on properites of PUR-PIR foams

    Open Research Data
    open access

    This work attempts to validate the possibility of replacing petrochemical polyols with previously synthesized bio-polyols and their impact on the structure and properties of rigid polyurethane-polyisocyanurate (PUR-PIR). The influence of bio-polyols addition on foam properties was investigated by mechanical testing, Fourier transform infrared spectroscopy...

  • Validation of polyurethane-wood composites properties

    Open Research Data
    open access

    This study focuses on the development of the PU-WC manufacturing method, the determination of properties of this type of composite, and the indication of its potential application.

  • Valorization of bio-based polyols synthesized via biomass liquefaction

    Open Research Data
    open access

    As the properties of polyols have a huge impact on the properties of manufactured polyurethanes, this study aims to determine the influence of polyethylene glycols with different molecular masses on the course of the biomass liquefaction process and bio-polyol properties. The obtained polyols were characterized by rheological studies. To confirm the...

    • A. Tkaczyk-Wlizło

    Canine mitochondrial genome is built of 16727 bp. Non-coding control region (mtCR), called also D-loop, begins with 15458 nucleotide and ends with 16727 nucleotide. The length of this fragment is 1270 bp (Kim et al., 1998). D-loop region is responsible for replication and transcription of mitochondrial DNA. Mutations that occur within it may cause irregularity...

    The DataSet contains the XRD patterns of the TeOx-BaO-BiO powder. The material was obtained by the sol-gel method.  The starting solution was prepared by mixing telluric acid (precursor), barium carbonate, and bismuth carbonate with thetraetylene glycol, water, ethanol, and acetic acid. (Samples molar concentration: 73TeO2-4BaO-3Bi2O3 and 73TeO2-3BaO-4Bi2O3)....

  • Investigations of the valence state of Co in a MnCoO ceramics

    Open Research Data
    open access

    McCoO ceramics materials were produced by solid state reaction and sintred in a furnance in air atmosphere for 20h. Annealing temperature was 600 Celsius degree. For investigations a series of samples, with a various composition was chosen: MnCoO, Mn, Co2O and Mn2CoO. Chemical behaviour of the Cobaltium was measured by XPS method.  The analyses were...

  • 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)....

  • 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.

  • 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...
