In the present work we report on the study of local atomic and electronic structure of gold nanoparticles funnctionalised by thiol and amine containing long-chain ligands. The study of nanoscale atomic structure is performed by means of X-ray absorption spectroscopy (XANES: X-ray Absorption Near-Edge Structure) and computer simulation. In consequence of the experimantally obtained data analysis and computer simulation it was obtained that strong bonding takes place when 11-mercaptoundecanoic acid is bound to the gold nanoparticles surface, forming a chemical bond Au-S 0.25 nm in length. Weaker bonding is observed when forming bond between dodecylamine and gold nanoparticles surface atom resulting in Au-N bond 0.23 nm in length. Supplementary XANES spectra analysis by means of density functional theory reveals the nature of formation of the investigated nanoscale structure.

A widespread technology with deep litter floor with broilers. Promising material for bedding are the straw materials. However, straw, held a simple reduction, does not meet the zootechnical requirements, in particular the recommended length of the cut should be 50 mm to 150 mm. Thus, there arises the problem of fractionation straw, obtained at harvest crops as waste. We carried out an analysis of the different types of fractional chopped straw with nodal connections without them. Studies have been conducted on the behavior of these types in an air classifier with a velocity change .

Tendencies of technological improvement of electronic chips led to reduction of their sizes, weight, development of functionality and decrease in power consumption. It allows us to discuss questions of developing renewable micro power sources which can provide power supply of autonomous microelectronic and micro circuitry systems for charge indication, paying attention to snow transfer, etc. 
The purpose of the paper is researching a profile of electrostatic field potential in the mountain district which was estimated as a possible use as a renewable micro power source.
It is found out that on windward sides of snow relieves the potential of electrostatic field exceeds three times to a similar  indicator for lee sides and is 80 V.  The potential is 3,5kV on polymeric surfaces (Nylon, teflon).

To date, the main method of mass production of advanced functional materials for various purposes is the ceramic technology. In the manufacture of multi-component oxide compounds using of ceramic technology is difficult to achieve high uniformity of chemical composition. For activation of the raw ingredients and make it more uniform use of chemical-tions (co-precipitation of salts or hydroxides, spray drying, Cryochemistry) and physical-tions (mechano-chemical, microwave, ultrasonic) methods. The paper presents the results of work on obtaining Ni-Zn-ferrite 2000NN radiation-thermal sintering. The influence of base composition and alloying additions on the electromagnetic properties of the ferrites. Confirmed the effectiveness of the use of surface-active additives To increase the density of the raw pieces and level parameters. We propose a model that explain schaya efficiency of dopants in the radiation-thermal sintering.

"This article is devoted to the development of the method for modeling elements of microsystems technology(MST) of membrane type. In this paper perforated membranes are considered and the impact of perforation on the mechanical properties of the membranes is examined. In numerical simulations of the elements it is proposed to use the equivalent mechanical parameters of perforated membranes obtained at the initial stage of the simulation. This will allow to obtain find the optimal parameters of perforation, reduce the time and resource modeling of MST elements. To test the technique numerical experiments were conducted for the two square membranes with sides 1.5 and 3 mm fixed on the contour of the same thickness. We studied the influence of the size of the perforation on the equivalent Young's modulus of the perforated membrane. "
