Macro and Micro-Scale Features of Thermoelectric PbTe (Br, Na) Systems: Micro-FTIR Spectroscopy, Micro-Seebeck Measurements, and SEM/EDX Observations
(Springer, 2014)
In this work, n-type and p-type PbTe doped with Br and Na, respectively, were thoroughly examined to determine the effect of the dopant on microstructure. Macro and micro homogeneity of the samples were studied by means ...
Thermal and mineralogical characterization of loess heavy clays for potential use in brick industry
(Elsevier, 2014)
This paper describes a study of 11 selected samples of loess soil from Serbia, by using differential scanning calorimetry, simultaneously with thermogravimetry and its differential calculation, known as simultaneous thermal ...
Advanced Optimization of Heavy Clay Products Quality by Using Artificial Neural Network Model
(Belgrade : Serbian Ceramic Society, 2014)
The effects of firing temperature (800–1100°C), chemical composition (expressed in terms of the content of major oxides - SiO2, Al2O3, Fe2O3, CaO, MgO, Na2O, K2O, MnO and TiO2), as well as several shape formats of laboratory ...
Al2Mo3O12/polyethylene composites with reduced coefficient of thermal expansion
(Springer, 2014)
Recently, polymer composites reinforced with low fractions of thermomiotic nanoceramics have triggered a lot of research. The efforts have been focused on achieving considerable reduction of the coefficient of thermal ...
Advantages of combined sintering compared to conventional sintering of mechanically activated magnesium titanate
(Belgrade : International Institute for the Science of Sintering, 2014)
In this article, the advantages of combined sintering in comparison with the conventional one, of mechanically activated magnesium titanate ceramic were investigated. The stoichiometric mixtures of MgO and TiO2 were ...
Preparation of pozzolanic addition by mechanical treatment of kaolin clay
(Elsevier, 2014)
Batches containing 5 kg of Serbian medium-quality kaolin clay were mechanically treated in a conventional ball mill for 10, 30, 60, 120, 600 and 1200 min of milling time. High reactive pozzolanic addition was obtained as ...
Structural, electrical and magnetic properties of nickel manganite obtained by a complex polymerization method
(Elsevier, 2014)
Structural, electrical and magnetic properties of nickel manganite ceramics obtained by sintering fine powders prepared by a complex polymerization method are given in this work. The phase composition of the synthesized ...
Highly sensitive graphene-based chemical and biological sensors with selectivity achievable through low-frequency noise measurement — Theoretical considerations
(IEEE, 2014)
We have developed a theory of the low-frequency noise caused by interaction of the analyte with the active area of chemical and biological sensors. The main result is an analytical expression for the spectral density of ...
