Novel utilization of fly ash for high-temperature mortars: Phase composition, microstructure and performances correlation
(Hoboken, NJ : John Wiley & Sons, 2015)
In this study, the feasibility of using fly ash to manufacture high-temperature mortars was investigated. The investigation was set to define preliminary characteristics of new types of mortars based on ordinary and/or ...
Up-converting nanoparticles synthesis using hydroxyl-carboxyl chelating agents: Fluoride source effect
(American Institute of Physics, 2020)
The synthesis of lanthanide doped up-converting nanoparticles (UCNPs), whose morphological, structural, and luminescence properties are well suited for applications in optoelectronics, forensics, security, or biomedicine, ...
Ultrasonic de-agglomeration of barium titanate powder
(Ultrasonics Sonochemistry, 2008)
BaTiO3 (BT) powder, with average particle size of 1.4 mu m, was synthesized by solid-state reaction. A high-intensity ultrasound irradiation (ultrasonication) was used to de-agglomerate micro-sized powder to nano-sized ...
Structural and functional properties of ZnO thin films grown on Si substrates by air assisted USP method from non-aqueous solutions at low-temperature
(Advanced Powder Technology, 2017)
In this work, we deals with the processing and characterization of transparent conducting ZnO thin films on p-type Silicon substrates (1 0 0) by air assisted Ultrasonic Spray Pyrolysis (USP) method. The thin films from ...
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 ...

(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 ...
Analysis of nonisothermal sintering of zinc-titanate ceramics doped with MgO
(Springer, 2008)
The aim of this work is to analyze nonisothermal sintering of zinc titanate ceramics doped with MgO obtained by mechanical activation. Mixtures of ZnO, TiO 2, and MgO (0, 1.25, and 2.5%) are mechanically activated for 15 ...
Mechanochemistry of titanium oxides
(Belgrade : Association of the Chemical Engineers of Serbia, 2009)
Mechanochemistry represents an alternative route in synthesis of nanomaterials. Mechanochemical routes are attractive because of their simplicity, flexibility, and ability to prepare materials by solid state reactions at ...
Polyaniline stabilization of magnetic particles and immobilization of α-amylase
(Belgrade : Association of Chemists and Chemical Engineers of Serbia, 2018)
Magnetic particles (MAG), obtained by standard procedure of coprecipitation of Fe2+ and Fe3+ in an excess of ammonia, and polyaniline modified magnetic particles MAG-PANI were used as carriers for immobilization of α-amylase ...
