Synthesis of thin films by the pyrosol process [Sinteza prevlaka pirolizom]
(Savez hemijskih inženjera, Beograd, 2002)
Among many aerosol routes, the Pyrosol process, due to its simplicity, low cost and quality of obtained films, represents a promising technique for the synthesis of thin films. The pyrosol process is based on the transport ...
Mechanochemical synthesis of yttrium manganite
(Elsevier Science Sa, Lausanne, 2013)
Yttrium manganite (YMnO3) is a multiferroic material, which means that it exhibits both ferromagnetic and ferroelectric properties, so making it interesting for a variety of technological applications. In this work, ...
Tuning of BiFeO3 multiferroic properties by light doping with Nb
(Elsevier Sci Ltd, Oxford, 2018)
Bulk ceramic samples of BiFeO3 were light doped (up to 1%) with Nb5+ in the place of Fe3+ (B-site doping) and their multiferroic properties were investigated using XRD, SEM, polarization (PMTS) and magnetization (SQUID) ...
Hydrothermally assisted synthesis of YMnO3
(Elsevier Sci Ltd, Oxford, 2015)
In this work single phase hexagonal YMnO3 powders were prepared starting from Y(CH3COO)(3)center dot xH(2)O, Mn(CH3COO)(2)center dot 4H(2)O, KMnO4 and KOH using methods of conventional (280 degrees C for 6 h) or microwave ...
Spectroscopic study of spinel ZnCr2O4 obtained from mechanically activated ZnO-Cr2O3 mixtures
(Elsevier Sci Ltd, Oxford, 2007)
A mixture of starting ZnO and Cr2O3 powders in equimolar quantities was mechanically activated by grinding using a high energy vibro-mil I for 0, 40 and 80 min. The spinet ZnCr2O4 was prepared from activated mixtures by a ...
Mechanochemical synthesis of bismuth ferrite
(Univerzitet u Beogradu - Tehnički fakultet u Boru, Beograd, 2013)
A powder mixture of Bi2O3 and Fe2O3 was mechanically treated in a planetary ball mill in an air from 30 to 720 minutes. It was shown that the mechanochemical formation of BiFeO3 (BFO) phase was initiated after 60 min and ...
Effect of Binder Molecular Weight on Morphology of TiO2 Films Prepared by Tape Casting and Their Photovoltaic Performance
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2012)
Titanium(IV) oxide in the form of anatase has proven to be the best choice for photoanodic material in dye-sensitized solar cells (DSCs). The aim of the work was to study the influence of binder molecular weight on the ...
Multiferroic bismuth manganite prepared by mechanochemical synthesis
(Elsevier Sci Ltd, Oxford, 2010)
Multiferroic bismuth manganite (BiMnO3) is known as a material that exhibits both ferromagnetic and ferroelectric properties making it interesting for various technological applications. Unfortunately, preparation of BiMnO3 ...
Phase evolution in Ce-doped yttrium-aluminum-based particles derived from aerosol
(Elsevier Sci Ltd, Oxford, 2007)
The common nitrates precursor solution leading to the Y3Al5O12:Ce3+ (YAG:Ce) composition with 2 at.% of cerium, is ultrasonically atomised and introduced into the tubular flow reactor at 320 degrees C. Having in mind that ...
Evolution of the microstructure of disperse ZnO powders obtained by the freeze-drying method
(Elsevier Science Sa, Lausanne, 2004)
Freeze-drying, as a cryochemical powder processing method is applied in the synthesis of ZnO submicrometer to narrosized powders. The process involves rapid freezing of the sprayed precursor solution, drying under vacuum ...
