In order to develop a constructive solution of flexible high efficiency thin-film solar cells based on the CdS/CdTe system adapted for the installation of a solar battery from such solar cells directly onto the standard solar thermal collector plate the serie of flexible solar cel cells samples with various thickness of functional layers it has been manufactured. The research of solar cells test samples carried out by optical methods and by measurement and subsequent analytical processing of illuminated current-voltage characteristics. It has been established that the absorption coefficient of flexible CdS/CdTe based solar cells in the visible range is 105 cm-1, and the reflection coefficient in the infrared spectrum region does not exceed 7-8 % which allows excluding absorber with a selective coating from collector because its function will perform directly by such solar cell. It has been shown that, due to a significant reduction of substrate weight for flexible solar cells, it was possible to achieve specific power values up to 2.0 kW/kg.

The spectral sensitization technology of heterophase "nonsilver core-silver haloid shell" microsystems that allows fixing a dye at both molecular and/or J-aggregated stages on the internal as well as external surfaces of a light sensitive shell has been proposed. The creation of heterophase "nonsilver core-dye-silver haloid shell-dye" microsystems is proved by the results of the spectrosensitometric and luminescence characteristics including the depth and surface development of the exposed layers.

The paper considers the effects of low intensity laser irradiation (LILI; 633 nm, 20–40 mW/cm2) as well as visible and infra-red polarized electromagnetic irradiation (VIRPEI; 480-3400 nm, 20–40 mW/cm2) on the liver mitochondria isolated from both the normal and type 2 diabetic rats. It was revealed that on the one hand the rate of oxygen absorption by mitochondria in rats with diabetes was decreased versus the quantity in rats of control group, but on the other hand the value was increased due to the LILI action. The respiratory data of control rats did not change after the of laser irradiation effect. The mitochondrial functions were decreased as the result of the VIRPEI influence. The respiratory processes are the basic ones for receiving the energy by various biological objects, both multicellular organisms and unicell ones, for example bacteria. Since the biological respiration is based on the electron transport chains functioning, isolated mitochondria is a model system for studying the respiratory processes. The application field of these effects is first of all biotechnology, particularly, cultivation of cells and tissues.

This research paper solves the challenge of plastic product marking. In particular, plastic cap marking. Nowadays, IR lasers (fiber, solid-state, gas lasers) are used for plastic marking, in most cases these are 1.06 µm fiber lasers, but plastics must contain metal additives for obtaining a high-quality marking with such a laser. And those additives are not safe for plastic products in the food industry. This problem is solved by using high-energy UV lasers. Therefore, the NII Laser Technology PJSC team has developed and produced a comprehensive system for high-resolution marking of both plastic products and other materials (metal, glass, ceramics) based on an ultraviolet laser. A combination of 2D-scanning technology, adaptive focusing, marking of objects in motion (on-the-fly), as well as a number of other technological and design solutions in this system made it possible to start production of conveyor lines for dynamic marking of beverage closures, crown caps, elongated plastic and metal caps amongst others that are used in the food industry. In comparison to the existing marking technologies, the developed laser marking comprehensive system provides high-speed (up to 100 thousand caps per hour) marking with text, digital and graphic data on the outer surfaces of the plastic produced without any special coloring agents, and allows getting a contrast image by using gray shading regardless of the surface color. At the present day, NII Laser Technology PJSC has carried out work to expand the capabilities of the laser marking comprehensive systems through the introduction of 3D scanning technology and the use of two band laser systems, that increase the product protection. The safety of using ultraviolet radiation for marking the internal surfaces of food packaging plastic elements is confirmed by the certificate on laboratory testing by INSTITUT NEHRING GmbH - Heesfeld 17-38,112 Braunschweig

The results of the development of a formalized mathematical model for describing the interaction of laser radiation with the plasma material intended to protect REM by reflecting this radiation are presented in this research. The basic structure of the physical model of solid-state plasma material is presented. It has been found out that the generation of the Langmuir noise in the protective layer of solid-state plasma of the screen of radio-electronic means provides shielding from laser radiation at a sufficiently small value of the field strength of the Langmuir wave. In this case, there is a reemission of laser energy in the opposite direction.

The research of the psychophysiological state of winterers of the Antarctic station "Academician Vernadsky" was carried out in order to establish the feasibility of their subsequent stay at the station and fulfill their service tasks. Short-term stay of polar explorers under difficult conditions causes stressful effects and nonspecific adaptive reactions. Their organisms must adapt to the exposure of various extreme factors and, in the first turn, natural ones. Considering that hematopoiesis is an important mechanism on which the ultimate adaptive result depends, a study of blood parameters was performed. It has been found that there are some changes in certain blood parameters that are not relevant with the reference norms for the studied polar groups. In this connection, there is a problem in adjusting the reference intervals for them. In order to determine the reference intervals, it is necessary to take into account the uncertainty of their establishment, having previously analyzed the sources of uncertainty.

The approach to the evaluation of the functional state of the human body as a system with a set of interrelated functional subsystems of the homeostatic type is proposed. The approach is considered on the basis of an assessment of the state of the respiratory subsystem, which can be described by a complex of statistically stable medical and biological indicators. Indicators obtained during monitoring of the state of polar explorers of the XXI Antarctic expedition at the station "Academician Vernadsky" in difficult conditions that can be attributed to the extreme. It was established that when forming the rules for making decisions on the suitability of winterers for further staying in the conditions of the action of extreme factors it is necessary to consider not only the values of the indicators of the state of the subsystems of the organism, but also their accuracy parameters. The analysis of the uncertainty of the obtained indicators by the proposed information model is carried out. It is shown that in this case it is necessary to take into account the features of a biological object, which has an individual and group variation.

In the present study we have focused on synthesis and characterization of nanocomposite for photodynamic therapy. The nanocomposite consisted of gold nanoparticles and photosensitizer Chlorin e6 incorporated into star-like polymer Dextran-graft-Polyacrylamide. The behavior of three-component nanosystem in the region of physiological temperatures was studied by using Dynamic Light Scattering. A small change in the size of polymer aggregates was observed at an increase in temperature from 25 ° C to 45 ° C. However, size of gold nanoparticles remained around 10 nm at all temperatures. The absorption spectra of nanosystem revealed the interaction of the photosensitizer Chlorine e6 with gold nanoparticles.In vitro testing of studied nanocomposite efficiency for Photodynamic therapy was carried out on the sub-lines of breast carcinoma MCF-7/S; MCF-7/Dox, and Jurkat cells. After irradiation with laser the death of 68.4% of MCF-7/S cells was registered. However, for MCF-7/Dox cells - 24.9%, for Jurkat cell line - 20 %. It was proved that prhotodynamic efficacy of proposed nanocomposite was depended on malignant cells type, while slight aggregation process not significantly affected nanosystem activity.

In the work presented is the theoretical description of optimal focusing of extended laser beam at long distances (over 1km). It is shown that in general case the optimal focusing condition does not coincide with the condition of formation of laser beam waist. The approximation is formulated, when the optimal focusing coincides with the beam waist. Obtained is the theoretical and experimental confirmation of linear dependence of minimum diameter of focusing spot from the focusing distance.
