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.

Cu_xCrSe₂ 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_xCrSe₂ has been studied with regards to defectivity in the copper sublattice. The boundaries of the Cu_xCrSe₂ homogeneity regions for the delafossitelike structure and for the cubic spinel CuCr₂Se₄ 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 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/m² and compressive strength increases by 35% to 575 MPa.

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 Na₂SO₄-Pb and K₂SO₄-Pb phosphors. The combined radiative electronic state is formed from intrinsic SO³⁻₄ - 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 3p₁ - 1s₀ in Pb²⁺ located in nonequivalent positions of the Na₂SO₄ lattice.

The paper presents experimental results of concentration polarization and ionic conductivity of nanocomposite thermoelectric materials K_0.01Cu_1.94S, K_0.02Cu_1.94S , K_0.03Cu_1.94S . According to X-ray phase
analysis, the synthesized samples are monoclinic jarleite Cu_1.93÷1.97S with an admixture of oxygen oxide Cu₂S 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_0.02Cu_1.94S . 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.
