Optical properties of nanocomposite films based on Ag/PMMA system
(Belgrade: Materials Research Society of Serbia, 2011)
As continue of our previous studies, three silver organosols with different nanoparticles
sizes were used to obtain nanocomposite films based on Ag/PMMA system. Among polymeric
materials, PMMA is well known as a polymeric ...
Application of polymer materials for production of evaporative pattern and development of new casting process
(Bor, Srbija : Tehnički fakultet Bor, Institut za rudarstvo i metalurgiju, 2012)
In this paper, results of the investigation of the polymer materials for evaporate patterns and their application in the new casting method (EPC process) are presented. The basic characteristic of EPC process is that ...

Adsorption study on natural clays as cement mineral additives: possibility of toxic metallic cations immobilization
(Serbian Ceramic Society, 2018)
Evironmetally safe mortars in which part of the cement binder was replaced by mineral
additives (i.e. zeolite, bentonite and fly ash) were designed. Fly ash, as fine powdery byproduct
of coal combustion, comprises heavy ...
Effect of Humic Acid on Growth of Zymogenous Consortium of Microorganisms Used in Bioremediation Process
(Japan Society for Environmental Chemistry, 2016)
Environmental pollution with toxic metals, petroleum-type contaminants and new classes of Persistent Organic Pollutants (POPs), such as perfluoroalkyl and polyfluoroalkyl substances (PFASs) is always a problem. Microorganisms ...
Oxygen Reduction on Palladium Modified Zeolite 13X
(Serbian Ceramic Society, 2014)
Palladium was dispersed over zeolite NaX by procedure of impregnation/thermal degradation of palladium acetylacetonate salt.
Samples characterization was performed by X-ray diffraction and SEM analysis. XR D analysis ...

In this paper, results of investigation of casting technology of complex thin-wall copper alloy castings with accent on Lost Foam casting procedure are given. Phases of casting procedure were investigated, along with ...
Modified monmorillonite as a nicotine adsorbent
(Serbian Ceramic Society, 2015)
The adsorptions of nicotine at 298 K from aqueous solution onto natural Wyoming
montmorillonite (Wy-M), acid-activated montmorillonite (Wy-MA) and alkali-activated
montmorillonite (Wy-MAL) were investigated. The Wy-MA ...
The minor influence of calcium doped phosphate tungsten bronze on the Briggs-Rauscher reaction dynamics / Мали утицај калцијумом допиране фосфат волфрамове бронзе на динамику Бригс−Раушер реакције
(National and University Library of the Republic of Srpska, 2018)
The Briggs-Rauscher (BR) oscillatory reaction is the oxidation of malonic acid in the presence of hydrogen peroxide and iodate in the acidic environment, which is catalyzed by ions of manganese. This reaction is very ...
