  • 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...

  • Analysis of the chemical composition of MnO-B2O3 glass

    Open Research Data
    open access

    Structural and thermal properties of xMnO−(100−x)B2O3 (where x = 40, 50 and 60 mol%) glass samples have been investigated with the employment of various techniques. Fourier transform infrared spectroscopy results revealed the influence of MnO on glass matrix. Decrease of B–O bond-related band intensities has been observed. MnO addition was found to...

  • The luminescence study of Ca14Zn6Ga10−xMnxO35 coumpounds.

    Open Research Data
    open access

    Manganese in the pentavalent state (Mn 5+) is both rare and central in materials exhibiting narrow-band near-infrared (NIR) emission and is highly sought after for phosphor-converted light-emitting diodes as promising candidates for future miniature solid-state NIR light source. We develop the Ca 14 Zn 6 Ga 10−x Mn x O 35 (x = 0.3, 0.5, 1.0, 1.25, 1.5,...

  • Imaging of morphological and physicochemical changes occuring in the structure of austenitic steel due to the thermal sensitization

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

    In polycrystalline materials, grain boundaries are always where phenomena such as surface diffusion, sedimentation and corrosion occur. They have a significant impact on the macroscopic properties of the construction material [1]. In addition to inhomogeneities such as manganese sulphide inclusions formed during the metallurgical process, interfacial...

  • Study of the chemical state of Gd in a Ba-La-Gd-Co based ceramic

    Open Research Data
    open access

    Barium, Lanthanum, Gadolinium and Cobaltium precursors were used for production of ceramic materials. Samples were produced by standard solid state reaction.  Samples were annealed at 300 Celsius degree in wet and dry atmosphere. Annealing takes 72h or 2h. Results of annealing on a Gadolinum were observed by X-Ray photoemission spectroscopy (XPS), OmicronNanotechnology....

  • Influence of the annealing condictions on the chemical structure of LaBaGdCo ceramics

    Open Research Data
    open access

    Ceramic samples based on Barium, Lanthanum, Gadolinium and Cobaltium were produced by solid state reaction.  After sintring in a furnance, samples were annealed at 300 Celsius degree in wet and dry atmosphere. Annealing takes 72h or 2h. Results of annealing were observed by X-Ray photoemission spectroscopy (XPS), OmicronNanotechnology.  XPS analysis...

  • Lanthanum investigations in ceramics annealed in a dry and wet atmosphere

    Open Research Data
    open access

    Ceramics based on Barium, Lanthanum, Gadolinium and Cobaltium were produced by standard solid state reaction from oxides and carbonate powders. After sintring, samples were annealed for 2 hours or 72 hours at 300 Celsius degree in a both: wet and dry atmosphere. Results of annealing on a chemical composition and valence state of lanthanum were observed...

  • 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...
