Influence of different bonding and fluxing agents on the sintering behavior and dielectric properties of steatite ceramic materials
(Elsevier, 2017)
The focus of the study was on providing insights into interconnections between sintering and development of the crystalline microstructure, and consequently variations in dielectric behavior of four steatites fabricated ...
Structure analysis of geopolymers synthesized from clay originated from Serbia
(Springer, 2017)
The paper presents chemical and structural analysis of geopolymer materials which are obtained by alkali-activated calcined clay (metakaolin) originated from Serbia under strictly defined conditions. Characterization of ...
Structural and chemical properties of thermally treated geopolymer samples
(Elsevier, 2017)
This article presents the results of the compositional, structural and morphological study of geopolymers synthesized from metakaolin and an alkali activator. The study involved the investigation of the structural and ...
X-ray spectra and electronic structure of the Ca3Ga2Ge3О12 compound
(Solid State Sciences, 2017)
The band structure of Ca3Ga2Ge3О12 with the garnet structure has been determined for the first time by X-ray emission and photoelectron spectroscopy. It has been established that the bottom of the valence band is formed ...
Novel modified nanocellulose applicable as reinforcement in high-performance nanocomposites
(Elsevier, 2017)
The influence of modification and vacuum/supercritical CO2 (scCO2) drying methods on the surface properties, morphology and thermal stability of cellulose nanocrystals (NC) was presented in this study. Introduction of ...
Preparation and characterization of bismuth germanium oxide (BGO) polymer composites
(Elsevier, 2017)
Bismuth germanium oxide Bi12GeO20 (BGO) has very interesting electrical, optical and magnetic properties. In order to make devices based on this material more flexible, its powder was used for preparing polymer composites. ...
Estimation of fractal representation of wind speed fluctuation by artificial neural network with different training algorothms
(Elsevier, 2017)
Since the wind speed fluctuation could cause large instability in wind energy systems it is crucial to develop a method for precise estimation of the wind speed fluctuation. Fractal interpolation of the wind speed could ...
Wind speed parameters sensitivity analysis based on fractals and neuro-fuzzy selection technique
(Springer London, 2017)
Fluctuation of wind speed affects wind energy systems since the potential wind power is proportional the cube of wind speed. Hence precise prediction of wind speed is very important to improve the performances of the ...
Dielectric properties, complex impedance and electrical conductivity of Fe2TiO5 nanopowder compacts and bulk samples at elevated temperatures
(Springer US, 2017)
In this work we have investigated changes in dielectric properties, electrical conductivity and complex impedance of Fe2TiO5 nanopowder compacts and bulk samples as a function of elevated temperature (room to 423 K compacts, ...
The impedance analysis of sintered MgTiO3 ceramics
(Elsevier, 2017)
In the present study the effect of preparation conditions on microstructure and electrical properties of MgTiO3 ceramics was investigated. Mixture of MgO and TiO2 powders was subjected to mechanical activation for different ...
