  - MATERIALS SCIENCE-POLAND - Year 2018

  Impedance spectroscopy measurements in various gas atmospheres were carried out in order to explain the doubts about the type of carriers and the mechanism of electrical conductivity in Bi-Si-O and Pb-Si-O glasses. In bismuth silicate glass, a typical ionic conductivity with oxygen ions as charge carriers was observed. The level of electrical conductivity of the glass at 400 °C was 5 × 10−8 S·cm−1 , with the activation energy of...

  - PHYSICAL CHEMISTRY CHEMICAL PHYSICS - Year 2015

  In this work, we have synthesized 5-thiocyanato-2′-deoxyuridine (SCNdU) along with the C6-deuterated nucleobase 5-thiocyanatouracil (6-D-SCNU) and studied their reactions with radiation-produced electrons. ESR spectra in γ-irradiated nitrogen-saturated frozen homogeneous solutions (7.5 M LiCl in H2O or D2O) of these compounds show that electron-induced S–CN bond cleavage occurs to form a thiyl radical (dU-5-S˙ or 6-D-U-5-S˙) and...

  - FUEL - Year 2023

  The growing demand for sustainable and clean energy sources provides the incentive for the development of alternative fuels. Simultaneously, the development of gas turbine technologies with flexible fuel supply systems enables the use of alternative non-fossil fuels that can play key roles in contributing to global efforts in meeting emissions targets. This paper presents the current state of knowledge on the production and potential...

  - Molecular Physics Reports - Year 2002

  Bazując na półempirycznym modelu wiązań kowalencyjnych w krzemie wyznaczono energie międzypowierzchni GaAs-Si. Obliczona energia międzypowierzchni GaAs-Si zależna jest od orientacji podłoża Si. Minimalna energia międzypowierzchniowa wyznacza odpowiednią konfigurację atomów w pobliżu powierzchni, która określa optymalne warunki heteroepitaksji GaAs na podłożach Si.
