  • Investigation of influence of adsorbtion of CO on characteristics of hold-up line on SAW with ZnO nanorods sensitive element

    Structure of  surface acoustic waves(SAW) of CO sensor was developed. SAW sensor include transceiving IDT and catoptric IDT, which is loaded on the impedance of ZnO nanorods. Peak of reflection SAW from IDT clearly observed as result Fourier transformation of time function of pulsed response. IDT loaded on resistance paralleled ZnO nanorods, which depends on the concentration of CO.

    Keywords: ZnO nanorods, device on SAW, CO sensor

  • Optimization of search the dust removal device for the enterprises of road and building manufactures

    In article are presented the analytical dependences, characterizing general and fractional efficiency on the basis of the is likelihood-stochastic approach, allowing to plan experimental researches and to develop design procedures of dust removal devices of the enterprises for manufacture of road and building materials. Research of dust properties and optimization on basis of constructive and regime parameters allow to provide demanded efficiency of catching of a dust.

    Keywords: "the is likelihood-stochastic approach, fractional efficiency, the dust removal device, optimization of parameters, manufacture of road and building materials "

  • Construction lending covenant

    Construction lending risks define a special operations procedure for lender. The most important measure to construction lending risk minimization are the covenants (information and financial). The information covenants are used for minimization the hidden information (pre-contractual opportunism), and financial covenants (positive and negative) – for minimization the hidden action (post-contractual opportunism). Institutionalization of covenants as a relevant control and supervision procedure allow to reduce information asymmetry and make the construction lending process less risky and more predictable for concerned parties (agent and principal).

  • Development of the new method for determination of 3D nano atomic and electronic structure of materials based on XAFS, XRD and Raman techniques

    Combined method which allows analyzing parameters of the nanoscale atomic and electronic structure of materials relying on three different methods (x-ray absorption spectroscopy (XAFS), x-ray diffraction (XRD) and Raman spectroscopy) was developed. The method was applied for the study of nickel oxide nanoparticles, which serve as an efficient catalyst for the artificial photosynthesis process.
