ZnO nanostructures are used in optical electronics and microelectronics, microsystems engineering. Characteristics of ZnO-based materials are improved by producing heterojunctions with oxides of other metals, including copper oxide. The use of quasi-one-dimensional structures provides the possibility for the total surface area of a heterojunction to be increased. Investigations aimed at the study of controlling the morphology of quasi-one-dimensional oxides are rather limited, so that the aspect considered in this regard continues to be very relevant. As a result, the search for the most efficient synthesis processes that give not only greater productivity, but also higher quality and improved material properties continues. A method for the synthesis of the ZnO/CuO heterostructure based on zinc oxide nanowires by pulse-periodic laser irradiation is described. The improvement of systems for shaping the laser beam with elements of diffractive computer optics provides an opportunity to control the processes involved in such synthesis.

Possibilities and features of thermochemical processes of interaction of powerful laser radiation with matter and optical systems for control of spatial distribution of beam intensity are described. Laser beams possess good focusing capabilities and provide the possibility to perform chemical reactions, including metal oxidation, locally and with high spatial resolution. With the use of laser beams with frequency modulation, a synergistic effect between the laser heat actions and the vibrations induced by the laser pulses is created. Thus, the coefficient of diffusion increases considerably as result of the nonstationary strain-stress state of the material. The synthesis of ZnO/Cu semiconductor-metal nanocomposite on the surface of brass samples is described. As a result of pulse-periodic laser treatment, anisotropic quasi-one-dimensional structures - zinc oxide nanowires - are formed on the material surface, i.e. on the conductive metal substrate. By using free-form diffractive optics to shape the laser beam, it is possible to control the chemical processes on the material surface. The resulting material structures are promising for sensor applications due to the sensitivity of ZnO to various chemical agents, biocompatibility, and the possibility of modifying it by various methods.

The analysis of processes evolving over time plays an increasingly important role in the modern world with the development of computing power. In this paper, the process of corrosive wear of the gas pipeline wall is considered, namely, the problem of regression of the pipe wall thickness value. A new method of temporal interpolation of the values of the wall thickness produced in accordance with the physical parameters of the transported gas condensate is proposed. Experiments on machine learning of regression models using the RANSAC algorithm are carried out, definitions of two metrics of correspondence of the trained models to physical reality are introduced. The experiments results showed that the use of the proposed interpolation method instead of spline interpolation allows for the increase of the first metric value by an average of 2 times and of the second metric value by 3 times.

In this study, we demonstrated that an even quantity of sub-wavelength domains is formed near the focal area of lens with big numerical aperture illuminated by cylindrical vector Gaussian beam (before and beyond the focus), in which the polarizing in every point revolves. Moreover, the polarization vector rotates in different directions inside the adjacent areas. Therefore, the spin angular momentum longitudinal component in these regions has opposite signs. Moreover, after the focal plane, the trend of the polarization rotation in all points of the light field distribution alters to the contrary one. Such dimensional division of the right-hand and left-hand turning of the polarization demonstrates the optical spin Hall effect.

To detect surface damage to buildings, it is necessary to involve workers who are at risk of industrial injuries when inspecting hard-to-reach areas of industrial premises. Attraction of special means, such as aerial platforms, safety systems, etc. increase the financial costs with this approach. The use of unmanned aerial vehicles, coupled with neural network algorithms, can simplify this procedure. Due to the inaccessibility, the problem of obtaining training data for neural networks arises, which can be solved by synthesizing them in a virtual environment.

This paper demonstrates the use of a neural network with additional training on synthetic data to identify, quantify, and measure short carbon fibers in electron microscope photographs. This task is of importance for the development of a short carbon fiber reinforced polymer material model, which requires precisely counting and measuring the fibers in a sample to determine the structural characteristics of the material. To automate the process of counting and measuring fibers, a neural network architecture called Mask R-CNN was chosen, which is designed to implement computer vision techniques such as: object identification, segmentation and quantification of instances. The selection of this type of architecture was due to the advantages of giving the masks for each instance, which allows obtaining approximate measurements of the fiber geometry. Due to the unavailability of fiber image data, the virtual imaging technique was chosen. Artificial images of short carbon fibers were recreated using the open API NX. A virtual data set with different fiber layouts was created. The results obtained in the test phase are good, for small numbers of fibers and with sparse clusters. There are still some problems in fully identifying the geometry of fibers that overlap with other fibers, which is a challenge to solve in future work.

Recently, the development in the field of optical technology is exemplary, precisely relating to the design of the components, necessary for optical integrated circuits. This research work investigates optical amplification action in a 2D Photonic Crystals (PhCs) based metasurface with variable radius even-positioned PhC-cavity. Two optical signals are used, i.e., data signal coupled into the optical structure using the phenomenon of the Guided-mode-resonances (GMR) and a pump signal index-guided into the optical structure. The pump signal is used to amplify the data signal and the PhC-cavity is used for spectral tuning of the device operating in the near-infrared (NIR) range. The designed structure comprises of an optical waveguide packed in between the layers of a substrate and cladding. The design and analysis of the proposed device is performed using Finite-difference Time-domain (FDTD) approach in an open-source software package. The investigated results present optical amplification action for a PhC-cavity of radius i.e., greater than the standard radius of the PhC-elements used in the investigated structure. Moreover, as a concluded fact, PhC-cavity nearer to the symmetric point of the optical structure will greatly influence the amplification phenomena and tuning of the GMR modes. The designed device can be used in applications relating to optical transistors, filters, and integrated circuits.
