“…As an acting electrode-cathode porous silicon was used, and as the second electrode-anode -a plate of graphite. The nanowires were tried to obtain by deposition in water equimolar solution of Zn(NO3)26Н2О and hexamine (С6Н12N4) at a concentration of 10-30 mM, pH 7 ± 0,1 and 0,1 M KCl [16].…”

Development of integrated sensors is a promising scientific and technical direction to create components for measurement and information systems. Among the different types of analyser one of the places are occupied by sensors of hydrogen containing compounds in gaseous and liquid condition (especially poisonous and carcinogenic). Fixing the presence of a substances in the gas or liquid environment is an actual task for scientific, industrial and medical application areas.The main goal of this paper an inexpensive microprocessor system for measuring and analyzing electrical properties of nanocomposite sensing material such as porous silicon on the base of current and capacity-voltage characteristics and its hardware and software applying is represented.The microprocessor system is designed for measuring sensors current-voltage and capacityvoltage characteristics based on porous silicon and nanocomposite structures and consists of the following units: power supply unit, DC voltage regulator, control and measurement module, RLC-meter E7-22, UART/USB and RS232/USB converters, measuring cell, PC. The software of the microprocessor system for measuring consists of the software for the control and measurement module implemented on the Atmega 128 microcontroller and the main device management software for the PC. The main program algorithm and software are implemented in the C# programming language in the Visual Studio 2017 environmentThe results of the comparison allow us to conclude that the implemented modules of the microprocessor system for sensors I-V-and C-V characteristics testing can be used in the development of portable environmental monitoring devices, to study porous silicon sensors using them.

“…Vacuum methods of obtaining highly disperse arrays have a number of advantages of chemical technologies [10][11][12] which are widely used now. Thus, the condensation of samples and their dispersion under high vacuum conditions makes it almost completely possible to dispose of uncontrolled impurities that have a primary influence on structures with a high surface fraction.…”

The results of research devoted to formation of ordered arrays of particles during melting process of tin films on amorphous carbon substrate are given in the present work. Using scanning electron microscopy the histograms of particle size distribution are constructed for films of different mass thickness. The size dependences of the most probable radius of particles, which are formed during the melting process, and the half-width values of the corresponding histograms are obtained as well. The excess energy, which provides a decomposition of the initially continuous film into separate islands, is estimated and its size dependence is built. As shown, the melting process of films, which are condensed in island structures, provides larger filling coefficients in comparison with the melting process of initially continuous films.
