Electrical conductivity of GMZ grade graphite as a function of fast neutron fluence

Cu x CrSe 2 materials can exist in the form of delafossite with a layered structure and exhibit multiferroic properties, or in the form of spinel and exhibit ferromagnetic properties, depending on the copper concentration. The stability of both forms of Cu x CrSe 2 has been studied with regards to defectivity in the copper sublattice. The boundaries of the Cu x CrSe 2 homogeneity regions for the delafossitelike structure and for the cubic spinel CuCr 2 Se 4 were determined by coulometric titration at room temperature. Analysis of the time dependence of cell polarization allowed us to estimate the diffusion coefficients in these materials.

The paper presents experimental results of concentration polarization and ionic conductivity of nanocomposite thermoelectric materials K 0.01 Cu 1.94 S, K 0.02 Cu 1.94 S , K 0.03 Cu 1.94 S . According to X-ray phase analysis, the synthesized samples are monoclinic jarleite Cu 1.93÷1.97 S with an admixture of oxygen oxide Cu 2 S and monoclinic chalcocyte. High values of total ionic conductivity are observed, ranging from 0.86 to 1.5 Cm/cm. The lowest ionic conductivity (0.86 Cm/cm at 355 ◦ C) is observed for alloy K 0.02 Cu 1.94 S . In addition, it was found that with an increase in the concentration of potassium in the studied materials, ionic conductivity tends to decrease, activation energy increases, but the characteristics of ion transport remain high, corresponding to superionic materials.

The effect of modified epoxy resin with polyurethane, silicone, and butadiene rubber and combined reinforcement with fiberglass and Kevlar on the strength properties of carbon fiber-reinforced plastic was studied. It was found that when rubber is introduced into the composition of the epoxy resin, polyurethane, and combined reinforcement according to the carbon fiber/Kevlar scheme in a ratio of 10:10 leads to an increase in impact strength by 42% to 273 kJ/m 2 and compressive strength increases by 35% to 575 MPa.

Analysis of the nuclear physics experiment often requires Monte Carlo simulation of the detector setup. Such kind of simulations often requires a quite advanced model of nuclear interaction. In this work we describe application of Monte Carlo simulation in the nuclear physic experiment, and discuss on example of elastic scattering how to apply well known High Energy Approximation (or Glauber model) to Monte Carlo simulation of the experimental setup.

The nature of the impurity emission and the process of creating intrinsic and impurity electron-hole trapping centers were studied by spectroscopic and thermal activation methods in Na 2 SO 4 -Pb and K 2 SO 4 -Pb phosphors. The combined radiative electronic state is formed from intrinsic SO 3− 4 - SO − 4 and impurity Pb + -SO − 4 electron-hole trapping centers in UV-irradiated phosphors with a photon energy of 6.2 eV at 80 K. Emissions of 3.2 eV and 3.6 eV resulting from irradiation with photons with an energy of 6.2 eV are associated with intracenter transitions of 3p 1 - 1s 0 in Pb 2+ located in nonequivalent positions of the Na 2 SO 4 lattice.
