Abstract: Dielectric anomalies specific for to relaxor ferroelectrics have been
found for the SrTiO3 – BiScO3 system. The relaxor properties of this system are rather unexpected because neither SrTiO3 nor BiScO3 are ferroelectrics. An X-ray diffraction analysis revealed that at room temperature the ceramic (1 – x)SrTiO3 – xBiScO3 samples with x = 0.2, 0.3 and 0.4 consist of a mixture of a cubic centrosymmetric Pm3m phase and a tetragonal polar P4mm phase. Lattice parameters for these phases increase as x increases. In addition, it was found by the electron backscattered diffraction method that at room temperature, the fraction of the cubic phase decreases and the fraction of the tetragonal phase increases as the mole fraction of BiScO3 increases. Phase coexistence is assumed to be one of the reasons for the relaxor properties of the system under study. - Dyachkova T.P., Melezhyk A.V., Morozov Zh.G., Shuklinov A.V., Tkachev A.G. Effects of the Nature of Oxidant and Synthesis Conditions on Properties of Nanocomposites Polyaniline/Carbon Nanotubes // Scientific article. Journal "Transactions of the TSTU", vol. 18 , Tambov. TSTU publisher house , 2012. (pdf-file)
Abstract: Nanocomposites based on carbon nanotubes, modified with polyaniline have been obtained. Polyaniline has been synthesized by oxidative polymerization of aniline. Potassium permanganate and ammonium persulfate have been used as oxidizers. The effects of the nature of oxidant and synthesis conditions on electoconductivity and morphology of the obtained materials have been studied. - Dyachkova T.P., Melezhyk A.V., Morozova Zh.G., Shuklinov A.V., Tkachev A.G. The Study of Adsorption of Copper and Nickel Ions by Polyaniline and its Nanocomposite with Carbon Nanotubes // Scientific article. Journal "Transactions of the TSTU", vol. 18 , Tambov. TSTU publisher house , 2012. (pdf-file)
Abstract: The adsorption of copper and nickel ions by polyaniline (PANI) and its
nanocomposite with carbon nanotubes (CNTs) in various conditions of preparation of the initial samples (deprotonation with ammonia, reduction with hydrazine) has been investigated. It is shown that deprotonation has little effect on the absorption of copper and nickel from solutions of acetates of these metals. Preliminary reduction of PANI and PANI/CNTs strongly increases absorption of copper, presumably due to redox reaction of copper ions with PANI leuco-base. - Selivanova Z.M., Khudyakov V.V., Samokhvalov A.A. Intelligent Information Measuring System to Control Thermal Conductivity of Nanoconcretes // Journal "Problems of Contemporary Science and Practice" Vernadsky University , Tambov. TSTU publisher house , 2012. (pdf-file)
Abstract: The paper describes an intelligent information-measuring system, which controls the thermal conductivity of nanoconcretes, enabling to provide high quality of nanoconcrete, according to the given specifications of thermal conductivity and, therefore, to ensure energy saving and high energy efficiency of buildings and structures constructed using nanoconcrete.
