AgCl microparticle materials, with novel heart-like morphology, were successfully prepared by means of a simple solution phase route, in which a small amount of hydrochloric acid, ethylene and PVP were introduced to the conventional polyol process. The obtained microparticle materials were characterized by scanning el…
We report the geometrical effect of graded buckled multiwalled carbon nanotube arrays on the electrical transport properties in the diffusive regime, via successive breakdown caused by the Joule heating. This breakdown occurs in the straighter region. Empirical relations involving the current-carrying ability, resista…
The work deals with the study of the phase and structural behaviour of the rare-earth substituted BiFeO3. X-ray powder diffraction examinations revealed that the polar R3c phase in the Bi1−xRExFeO3systems with RE = Er, Tm and Yb do not exceed 7, 4 and 3 mol.% of rare earth, respectively. Partial substitution of Er and…
An updated software package for the simulation of point diffraction pictures and the computation of several crystallographic characteristics of martensite crystals in alloys with the shape-memory effect is presented. Optimization was carried out for the procedure of the analysis of the orientation relationships betwee…
It is known, that the presence of oxide films and nonmetallic inclusions on a high-voltage electrode surface considerably reduce a vacuum gap electric strength. One of this phenomenon causes is electric charge occurrence in them, which one increases an external electric field strength. The charged particles postemissi…
The adsorption of two reactive dyes, Orange 16 (RO16) and a Reactive Red 120 (RR120) by Mg/Al-NO3layered double hydroxide in single and binary mixture (1:1 ratio) was conducted in a batch mode. Spectrophotometric method using first order derivative and zero crossing was applied to analyse colour removal of RO16 and RR…
Molecular nitrogen adsorption on single platinum and titanium nanoclusters is investigated by scanning tunneling microscopy and spectroscopy, including the use of an inverse scheme of spectroscopic measurements. Some regularities of the occurring processes are found.
Carbon nanotube and graphene based materials and devices have been extensively studied since they were discovered and are considered as potential building blocks for nano-scale circuits in virtue of their unique mechanical, electrical and thermal properties. Numerous other potential applications in areas ranging from…
In the presence of arc, partial discharge and thermal discharge, SF6decomposes into a wide variety of active products which possess different chemical properties. This paper reports on research in SF6decomposition relating to the ageing- and fault problems of the insulating materials in the gas-insulated equipment. Un…
X-ray diffraction, BET measurements, scanning electron and optical microscopy were used to analyze the properties variation of hydrothermal nanocrystalline powder with a composition 90 wt% Al2O3-10 wt%ZrO2(CeO2, Y2O3) after thermal treatment in the temperature range 400–1300 °C. The composition of the ZrO2-based solid…
A new one-dimensional (1D) zigzag chain coordination polymer [Co(Bpdc)(Dpa)] n (H2Bpdc = benzophenone-4,4′-dicarboxylic acid, Dpa = 2,2′-dipyridylanine) (I) has been synthesized under solvothermal conditions and characterized by elemental analysis, IR, and X-ray single-crystal diffraction. The X-ray diffraction analys…
The control system of industrial plant for ion-plasma treatment of large reflectors is presented in the report. Brief description of the structure and technological capabilities of the plant is given. The selection of structure of the control system and master controller is justified. The principles of the controller…
To study the effect of the temperature sensor on the spacers, the experimental platform of the temperature sensor and spacers model is constructed in this paper. It is studied that the flashover process is acquired with increasing the voltage using the sensor installing on the surface of the spacers, the simulated mea…
Catalytic activity and surface properties of the mixed catalysts for the dimethyl ether synthesis from CO and H2are presented in paper. Catalytic experiments were carried out in flow reactor at 3 MPa and temperature interval 200-260°C. As a catalyst for methanol synthesis it was used CuO/ZnO/Al2O3sample and as catalys…
Eco-friendly (Na, K) Nb03 (NKN)-based piezoelectric ceramic materials were fabricated by conventional ceramic method for shear mode piezoelectric energy harvesting application. NKN-LiTaO3 (LT) based compositions were adopted for the high d15xg15 which is proportional to harvested energy density. The composition 0.935(…

The interaction of stem cells with the surrounding matrix environment is crucial for cell fate. The development of biomatrices that recapitulate the in vivo environment is a key component to driving differentiation of pluripotent cells into lung endoderm precursors. We investigate whether decellularized lungs with int…
This research has looked into the treatment process of wood waste generated from industrial waste within the region and in order to modify the problem that may occurred during the mass balance were analyzed for development of suitable solid waste recycling network regionally. As as result, quite amount of wood waste a…
Background and Aims: An overview is presented of a potent approach for treating cancer that uses nanoparticles to deliver anticancer drugs. Since these drugs are neither specific nor targeted to the cancer cells, improved delivery of them appears to be a reasonable challenge. Methods: 9-nitrocamptothecin (9-NC) loaded…
