The application of the zeolyte powder for the construction of the dense composite membranes for the carbon-dioxide separation / Primena zeolitnih prahova za izradu kompozitnih polimernih membrana za separaciju ugljen-dioksida
(Savez inženjera i tehničara Srbije, Beograd, 2015)
The main task of the work is to construct the polymeric membrane that could be used for the waste gases treatment. For this purpose, membrane must have high permeability for the carbon dioxide and low permeability of the ...
Simulation of blast furnace operation during the substitution of coke and pulverized coal with granulated waste plastic / Simulacija rada visoke peći prilikom supstitucije koksa i sprašenog uglja granulisanom otpadnom plastikom
(Savez inženjera i tehničara Srbije, Beograd, 2014)
The possibility of using the waste plastic as reducing agent in blast furnace for obtaining pig iron is in focus for the past couple year. The simulation of blast furnace process in BFC software has been performed in order ...
Impact testing with controlled energy of multiaxial aramid fabrics with various types of reinforcement / Ispitivanje udarima kontrolisane energije multiaksijalnih aramidnih lamina sa različitim tipovima ojačanja
(Savez inženjera i tehničara Srbije, Beograd, 2015)
The physical and mechanical properties of the six samples of polyurethane/p-aramid multiaxial fabric forms (Kolon fabrics) were analyzed by high speed impact tester. The samples were impregnated with 10 wt.% poly (vinyl ...
Effect of alumina based particles on mechanical properties and resistance to acryloid composites cavitation / Uticaj čestica na bazi aluminijum oksida na mehanička svojstva i otpornost na kavitaciju akriloidnih kompozita
(Savez inženjera i tehničara Srbije, Beograd, 2018)
In the processes of preservation and restoration of sculptures and archaeological objects, copolymer materials of acrylate type are used because they have proved useful in conservation practice. The main disadvantage of ...
Application of alumosilicate polymers based on metakaolin in adsorption of cadmium ions from wastewater / Primena alumosilikatnih polimera na bazi metakaolina u adsorpciji jona kadmijuma iz otpadnih voda
(Savez inženjera i tehničara Srbije, Beograd, 2018)
Alumosilicate polymers (geopolymers) based on metakaolin as precursor and alkaline activators of different concentrations (2M, 4M, 6M and 8M NaOH/Na2SiO3) were used to remove ions of cadmium from wastewater. Experiments ...
The impact of wood fiber surface modification on physical properties of wood-polymer composites / Uticaj modifikacije površine vlakana drveta na mehanička svojstva kompozita polimer-drvo
(Savez inženjera i tehničara Srbije, Beograd, 2016)
In this paper, the impact of wood fiber surface modification on mechanical properties of poly-(methyl methacrylate)(PMMA)-wood composite was examined. FTIR analysis has shown that the wood fiber surface modification was ...
