Ispitivanje adsorpcionih svojstava elektrofilterskog pepela sa deponije termoelektrane „Moravaˮ u odnosu na fosfat-jone prisutne u rastvoru
(Inženjerska komora Srbije, 2018)
In this study we prepared adsorbents on the basis of clinoptilolite-rich zeolitic tuff (Slanci deposit, Beograd), and chitosan, as well as partially cross-linked chitosan by glutaraldehyde. We investigated removal rate of ...
Chromatographic behavior and lipophilicity of s-triazine derivatives on silica gel impregnated with paraffin oil
(Univerzitet u Novom Sadu, 2010)
The chromatographic behavior of four group of s-triazine derivatives (14 compounds) has been studied by TLC on silica gel impregnated with paraffin oil. Retention mechanism has been determined using the following mobile ...
Estimation of the correlation between the retention of s-triazine derivatives and some molecular descriptors
(Univerzitet u Novom Sadu, 2011)
In this study, 14 newly synthesized s-triazine derivatives were investigated by means of reversed-phase thin-layer chromatography (TLC) on C-18 stationary and two different mobile phases: acetonitrile-water and methanol-water. ...
Cavitation of refratory samples based on talc and domestic zeolite / Ispitivanje vatrostalnih uzoraka na bazi talka i domaćeg zeolita na dejstvo kavitacije
(Savez inženjera i tehničara Srbije, Beograd, 2018)
Using domestic zeolite from Igroš as row material for ceramic samples for application in condition of cavitation erosion. Samples based on talc with 15 % of zeolite, from Igroš, sintered at 1200oC were used in this ...
Fracture toughness of base and weld metal of aluminum alloy EN AW 7049A T652 FSW joint
(Serbian Welding Society, Belgrade, 2018)
The paper analyses the impact of the tool geometry on the friction stir welding (FSW) method on fracture toughness values of the base metal (BM) and weld metal (WM) of a butt welded joints of a high strength aluminium ...
Formation and development of damage of basalt under the effect of cavitation / Nastajanje i razvoj oštećenja bazalta pod dejstvom kavitacije
(Engineering Society for Corrosion, Belgrade, Serbia, 2019)
The paper examines the cavitation resistance of the cast basalt samples. Samples were obtained by melting, casting and thermal treatment of crushed basalt rocks from the Vrelo Kopaonik deposit. The experiment was conducted ...
Comparison of the formation and development of cavitation damage on cast and sintered samples based on basalt / Poređenje nastajanja i razvoja kavitacionih oštećenja livenih i sinterovanih uzoraka na bazi bazalta
(University of Belgrade, Technical Faculty, Bor, 2019)
The paper examines the resistance to the effect of cavitation of glass-ceramics based on basalt. Two types of samples were investigated: cast and sintered samples based on basalt.The cavitation erosion test was performed ...
Optimizing the content of nickel in flux-cored wire intended for welding micro-alloyed steels / Optimizacija sadržaja nikla u punjenoj žici namenjenoj za zavarivanje mikrolegiranih čelika
(DUZS - Društvo za unapređivanje zavarivanja u Srbiji, Beograd, 2014)
This paper presents the results related to organizing production of flux-cored wire alloyed with Ni and Mo according to standard AWS A5.29 intended for the MAG welding process. On the experimental line for steel strip ...
Investigations of the possibilities of stillage utilization from the bioethanol production on corn / Ispitivanje mogućnosti korišćenja džibre iz proizvodnje bioetanola iz kukuruza
(Nacionalno društvo za procesnu tehniku i energetiku u poljoprivredi, Novi Sad, 2010)
Bioethanol produced by fermentation of biomass, such as sugar, starch, or lignocellulosic materials, is one of the most important renewable energy resources. An average thin stillage amount produced in the bioethanol process ...
