We report on possible applications of the digital twin technology. We analyzed digital twin structures of various types considering their parameters in terms of usage. A circuit board model was designed and the device behavior was predicted during its operation at high temperatures close to critical or above critical values. The data obtained allows to optimize the device operation regimes and produce timely adjustments to the design.

We briefly review the analytical models that describe toughening and fracture toughness reduction in ceramic/graphene composites. We consider such mechanisms of toughening as crack deflection and crack bridging. We examine the effect of pores and fracture along ceramic/graphene interfaces on the fracture toughness reduction at a high graphene volume fraction. The effect of grain boundary sliding on the fracture toughness of ceramic/graphene composites is also considered.

We fabricate the samples with two layers of silver nanoparticles embedded in ZnO film exploring sol–gel method by varying the annealing temperatures. The structural properties of the samples are determined by transmission electron microscopy. The effect of the annealing temperature on the nanoparticles plasmon absorption spectra is studied. Annealing at 570 °C results in a shift of the plasmon absorption maximum from 580 nm to 620 nm, due to an increase in the nanoparticles average size from 63 nm to 74 nm. Increasing the annealing temperature to 650 °C results in a shift of plasmon absorption maximum back to 580 nm due to a decrease in the nanoparticles size to 61 nm. Before annealing, the silver nanoparticles of the upper layer locate on top of the nanoparticles of the bottom layer, however, in the plane of the layers, they are arranged randomly at a distance of 30 to 150 nm from each other. As a result of the annealing, the system tended to be ordered, as a result, the nanoparticles in the layers become to be distributed equidistant at 40–70 nm between them; the nanoparticles of the upper layer tend being located between the nanoparticles of the bottom layer.

We analyze the preference of various types of misfit dislocation (MD) formation in film/substrate κ-Ga2O3/α-Al2O3 and κ (AlxGa1–x)2O3/κ-Al2O3 heterostructures. We consider two possibilities for variation in films growth orientation (defined by inclination angle ϑ) for these heterostructures with inclination axes about either [100] or [010] crystallographic directions. We study dependences of the critical film thickness for MD formation on the inclination angle ϑ for heterostructures under consideration. We find the presence of two special orientations (ϑ ~ 26° for [100] heterostructure, ϑ ~ 28° for [010] heterostructure, and ϑ = 90° for both inclination types) of κ-Ga2O3/α-Al2O3 heterostructures, for which the formation of MDs is energetically unfavorable. We show that formation of pure edge MDs is easier for [010] κ-(AlxGa1–x)2O3/κ-Al2O3 heterostructures than for [100] heterostructures, and it is vice versa for mixed MDs in these heterostructures.

The molecular dynamics method is used to calculate the dependence of pressure on temperature at a constant volume for a bundle of carbon nanotubes (CNTs) considered under plane strain conditions. A chain model with a significantly reduced number of degrees of freedom is used for modeling. The influence of the CNT diameter is analyzed. It was found that for some parameters of the model, the pressure in the CNT bundle can decrease with increasing temperature, which is equivalent to the effect of negative thermal expansion.

In this article, an approach to lattice design for two two-dimensional allotropic materials is proposed. The approach is based on the use of crystal lattices of disclinated graphene known as pseudo-graphenes. The approach is demonstrated on pseudo-graphenes G5-7v1 and G5-6-7v2 and target crystals originated from molybdenum disulfide and phosphorene. Geometry optimization done by density functional theory calculations display that the designed lattices for new materials are structurally stable, which means that they could be synthesized and that the new approach could successfully be used to produce lattice designs for novel two-dimensional allotropic materials.

Lithium-ion batteries are still efficient and reliable energy storage systems and are widely used in portable electronics and electric vehicles. This review describes the types of currently existing lithium batteries, systems with anodes, cathodes and electrolytes made of various materials, and methods for their study. Specifically, it begins with a brief introduction to the principles of lithium-ion batteries operation and cell structure, followed by an overview of battery research methods. Particular attention is paid to the use of nanosized particles for the modification of electrodes and electrolytes, as well as the copolymerization of individual polymers of the gel-polymer electrolyte. The review analyzes possible future developments and prospects for post-lithium batteries.

The elastic models of radial core-shell nanowires with diffuse interphase boundaries are suggested. The concept of eigenstrain is employed to consider a misfit stress distribution induced by diffusive interfaces with different range of distinctness. The eigenstrain profile described by the misfit parameter is approximated by piecewise-linear, error and arctangent functions. For these approximations the elastic stresses in core-shell nanowires are analytically derived, illustrated with plots and discussed in detail.
