  • Quality control of the production work on the consolidation of soil foundation using the GPR subsurface sensing

    The paper proposes to perform quality control of the production work on the consolidation of soil foundation with the use of the method. Application of geo-radiolocation sensing allows to specify and complement the results of engineering and geological surveys, as well as capture the changes taking place in the grounds of foundations after work on fixing them. This will provide a comprehensive picture of the grouting in the underlying foundation of the building and provide a reliable and simple quality control work.

  • The investigation of properties of gas sensitive materials based on SiO2SnOxCuOy thin films used in gas sensors for multisensory air monitoring system

    The establishment of automated air monitoring systems is a promising way of the air monitoring devices development. The comparative analysis of literature has shown that thin films based on semiconductor metal oxides are effective and widely used material for air monitoring systems creation. In order to create effective and more sensitive sensors it is important to research processes that occur on the surface of the gas sensitive material when it contacts with different substances. The processes that proceed on the surface of gas sensitive material based on SiO2SnOxCuOy during the interaction with molecules of nitrogen dioxide. Quantum chemical calculations have shown that there are three possible mechanisms of interaction between the molecules of nitrogen dioxide with a surface of gas sensitive material.

  • Development of technology of fabricating unheated gas sensors based on polyacrylonitrile for hybrid sensor systems

      Technology of fabricating unheated gas sensors based on polyacrylonitrile (PAN) using different temperature and time modes of a two stages IR-pyrolyze is developed for the remote control of the human condition. Gas-sensing elements based on PAN films and cobalt- and copper-containing PAN films are fabricated. Gas sensitive characteristics of the gained samples to CO, Cl2 and CHCl3 in atmospheric conditions are determined. We have found that gas-sensitivity of the samples depends on the composition of the original film-forming solution and on the process parameters of fabricating the film material. Moreover the samples show sensitivity and selectivity at room temperature. The benefits of this study is that films based on PAN and metal-PAN are the most promising material for electronic engineering including gas sensors for the remote monitoring of the human condition.
