Synthesis of Anatase Nanopowders by Sol-gel Method and Influence of Temperatures of Calcination to Their Photocatalitic Properties
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2015)
The titanium dioxide (TiO2) nanopowders were produced by sol-gel technique from tetrabutyl titanate as a precursor, varying the temperature of calcination (from 500 to 550 degrees C with the step of 10 degrees C). XRPD ...
Assessment of spatial and temporal variations in trace element concentrations using honeybees (Apis mellifera) as bioindicators
(Peerj Inc, London, 2018)
With the increase in anthropogenic activities metal pollution is also increased and needs to be closely monitored. In this study honeybees were used as bioindicators to monitor metal pollution. Metal pollution in honeybees ...
Synthesis and characterization of new refractory coatings based on talc, cordierite, zircon and mullite fillers for lost foam casting process
(Polska Akad Nauk, Polish Acad Sciences, Inst Metall & Mater Sci Pas, Warszawa, 2014)
Refractory coatings based on different refractory fillers (talc, cordierite, zircon and mullite) for application in Lost Foam casting process were investigated. Design and optimization of the coatings composition with ...
Functional, rheological and sensory properties of probiotic milk chocolate produced in a ball mill
(Royal Soc Chemistry, Cambridge, 2016)
The aim of this study was to investigate the survival of probiotics (Lactobacillus acidophilus NCFM, Lactobacillus rhamnosus HN001 and Bifidobacterium lactis HN019) in milk chocolate masses prepared at temperatures 35 ...
The Galvanostatic Reduction on Modified Platinum Electrode and Determination of Trinitrotoluene in Neutral Solution
(Esg, Belgrade, 2013)
The study of the electrochemical reduction on acetonitrile modified platinum electrode and determination of trinitrotoluene (TNT) in neutral solution by simple galvanostatic technique is presented here. The obtained ...
Synthesis of silver doped hydroxyapatite nanospheres using Ouzo effect
(Processing and Application of Ceramics, 2016)
Nanoemulsion technique, based on Ouzo effect, was applied for synthesis of the pure and silver doped (2.5 and 5 mol%) calcium hydroxyapatite (HAp). After calcination at 500 degrees C fully crystallized powders were obtained. ...
Synthesis and characterization of spider silk calcite composite
(Univerzitet u Novom Sadu - Tehnološki fakultet, Novi Sad, 2016)
Spider silk poses excellent mechanical properties, tenacity and elasticity and it has been used as a template for calcite mineralization to improve load bearing strength of osteoconductive calcite. The samples were obtained ...
Numerical analysis of thermal stresses in welded joint made of steels x20 and x22
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2014)
Stress calculation of steam pipeline is presented, focused on the welded joint. Numerical calculation was peiformed using the finite element method to obtain stress distribution in the welded joint made while replacing the ...
