The object of the present study is the possibility of the application of films which belong to the class of diamond-like (DLF - diamond-like film), i.e. containing a substantial concentration of carbon atoms linked by SP3 bonds typical for the structure of diamond to be further used as the dielectric and protective layer to obtain strain-sensing gauges based on samarium monosulphide (SmS). Unlike other traditional diamond-like films (a-C:H) films under consideration contain circuits ... -Si-O-Si-O- .... This feature provides diamond-like silicon-carbonic films (SC DLF) with a unique set of physical and chemical properties and a wide range of applications. The study was conducted in order to create the technology of thin-film interlayer dielectric with high dielectric strength suitable for various types of gauges (piezoresistive, thermal, etc.) intended for abrasive and chemically aggressive media.

The influence of ZnO nanograin sublayers deposited at the initial stage of the electrodeposition on morphology, structure, optical and electrical properties of the nanostructured arrays of this material produced in the pulsed electrodeposition mode has been investigated. It is shown that the formation of these sublayers contributes to enlargement of the crystal grains and the formation of separate zinc oxide nanorods, which are perpendicular to the surface of the substrate. Moreover, the zinc oxide array electrodeposited in the pulsed mode with using nanograin sublayers has higher specific resistance, better transparency, scatters less visible light and has an appropriate optical band gap.

In the following article, a design of a low-volume tethered aerostatic system is examined, that is intended for meteorology observations at the altitudes up to 1000 meters. An original aerodynamic configuration of the machine has been designed, which utilizes wings as a source of additional lift (a hybrid design). This approach allows to effectively maintain the required height of flight in windy weather, in contrast to classic tethered balloons. The paper presents the aerodynamic characteristics of the machine (dependent on the angles of attack and glide), which were obtained by computing that utilized the three dimensional numerical modeling within the framework of the solutions of the Navier-Stocks equations, averaged by the Reynolds method. We have devised a two-mode onboard control system. In the mode of stabilizing the machine’s angular position, the required values of bank and pitch angles are maintained, which is crucial to the proper functioning of the target equipment. The mode of height stabilizing prevents the unacceptable loss of height in downward air currents. The required degree of steadiness in the axis of the course is achieved by introducing selection options for the position of the tether’s attachment point. The article presents the results of a simulation of the aerostat's flight dynamics. The dynamic impact of the machine on the tether cable is analyzed. The critical speed of the machine is defined, with regard to the tether's durability. It is demonstrated that the machine meets the desired requirements. © Research India Publications.

In order to create thin-film photovoltaic converters based on cadmium sulfide and telluride experimental studies of the process of cadmium telluride magnetron sputtering with direct current,and the impact of a magnetron sputtering mode on CdTe films crystalline structure were carried out. CdTe films for the base layers of film photovoltaic converters were obtained on flexible polyimide substrates by magnetron sputtering with direct current for the first time. It was found that increasing the magnetron discharge current up to 80 mA leads to increase in coherent scattering regions what is due to an increase in the thickness of the cadmium telluride films of the hexagonal modification having a columnar structure. A further increase in the discharge current leads to a decrease in the size of coherent scattering regions what is caused by the thermodynamical output formation of low-angle boundaries. It was shown experimentally that the “chloride” processing of the obtained cadmium telluride layer leads to the transformation of the metastable hexagonal modification cadmium telluride in a stable cubic modification. At the same time,due to the eutectic recrystallization,increase in the sizes of coherent scattering regions by a decade and the microstrain level reduction in 1.5 times are observed. © 2016,International Journal of Pharmacy and Technology.

The paper describes the samarium monosulfide (SmS) synthesis and methods of obtaining films to produce a primary semiconductor converters with high sensitivity to deformation, with linearity characteristics, with high thermal and radiation resistance. Such semiconductor converters can be used in the design of film thermistor with improved performance. The low material and energy producing films of samarium monosulfide potentially allows to achieve a high level of commercialization of film thermistors on them. It is shown that the main problem of the production of films of samarium monosulfide device quality is a violation of their stoichiometry, which leads to non-reproducibility of thermistor operating parameters. It was shown that the optimal method for synthesis of stoichiometric monosulfide samarium is the reaction of samarium with sulfur and followed homogenizing annealing. It was established that the methods of the explosive evaporation and chemical decomposition of organometallic compounds allows to obtain thin films of monosulfide samarium. The presence of oxygen in the process of obtaining sensitive elements of the monosulfide samarium causes decrease in their functional parameters and defines features of their functional parameters. This is due to partial oxidation films SmS and contamination oxysulfide. Therefore design thermistor based on samarium monosulfide should wear appropriate protective layers. © Research India Publications.
