Synthesis of f-doped LiFePO4 via precipitation method
(Belgrade : Materials Research Society of Serbia, 2013)
Fluorine-doped, olivine-structured LiFePO4 suitable for cathode material in rechargeable lithium batteries was prepared by aqueous precipitation followed by high temperature treatment at 700°C under slightly reductive ...
Synthesis and characterization of Li2FeSiO4/C composite
(Belgrade : Materials Research Society of Serbia, 2012)
Polyoxyanion compounds, particularly the olivine phosphate LiFePO4, are receiving considerable attention as cathodes for rechargeable lithium batteries. Despite its numerous advantages, olivine phosphate severely suffers ...
Sinterovanje i svojstva sinterovanog ZnTiO3
(Belgrade : University of Belgrade, Faculty of Physical Chemistry, 2011)
Ultrafini prah cink-metatitanata veličine čestica 40 do 80 nm podvrgnut je prilikom sintetskog dela tretmana uticajima pritiska i temperature korišćenjem procesa presovanja i reakcionog sinterovanja. S obzirom na nestabilnost ...
Sinteza, strukturna i elektrohemijska svojstva LiFePO4 i Li2FeSiO4 kao katodnih materijala za litijum-jonske baterije
(Belgrade : University of Belgrade, Faculty of Physical Chemistry, 2016)
Predmet istraživanja ove doktorske disertacije su litijum gvožđe(II) fosfat (LiFePO4) i litijum gvožđe(II) silikat (Li2FeSiO4), koji predstavljaju novu generaciju polianjonskih interkalarnih katodnih materijala za ...
Quantitative metallography modern metods
(Belgrade : Serbian Ceramic Society, 2016)
This paper has been concerned with the classical Stereological targets V, S, L, and N only, namely with so-called first-order properties. Stereology is now drifting rapidly toward second-order methods, aimed at quantifying ...
Shungite - a Russian mineral: possible application as a microwave absorber
(Belgrade : Materials Research Society of Serbia, 2018)
The paper presents results of investigation of the influence of mechanical activation of shungite, a Russian natural mineral rich in silica and carbon, on its sintering behavior. The mechanical activation of the starting ...
New aspects in processing of hydroxyapatite ceramics
(Belgrade : Serbian Ceramic Society, 2017)
Sintering of hydroxyapatite ceramics has been a challenging topic for decades since the material has good bioactivity, proven biocompatibility, low cost, and high availability. Besides its biomaterial applications, ...
Crystal structure and X-Ray spectroscopic properties of R.E.2Ni12P5 compounds
(Belgrade : Materials Research Society of Serbia, 2018)
We have studied experimentally and theoretically the electronic structure and x-ray absorption spectrum at the R.E.L3 - edge and x-ray emission spectra of Ni and P in the R.E.2Ni12P5 compounds. Crystal structure of the ...
Molecular design of nanoparticles and functional materials by sintering
(Beograd : Tehnološko-metalurški fakultet Univerziteta u Beogradu, 2012)
Nanosized powders present an excellent starting point for the formation of nonporous materials during the sintering process. Narrow particle size distributions and sufficiently small sizes of the precursor powders typically ...
