Corrosion of cannon 75/27, model 1911. déport, from the collection of the Military Museum in Belgrade / Korozija topa 75/27, model 1911. deport iz kolekcije Vojnog muzeja u Beogradu
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2012)
This paper analyzes the state of the French Cannon 75/27 model 1911. Déport made of steel. The amount of non-corroded materials, the presence of cracks and other defects in the cannon were determined by the radiographic ...
Dynamic mechanical properties of aramid fabrics impregnated with multiwalled carbon nanotubes / Dinamičko mehanička svojstva aramidnih lamina impregnisanih sa višeslojnim ugljeničnim nanocevima
(Engineering Society for Corrosion, Belgrade, Serbia, 2013)
Carbon nanotubes (CNT) represent allotropes of carbon with a cylindrical nanostructure. In multiwalled carbon nanotubes (MWCNT), graphitic layers make up concentric tubes. The multiwalled nanotubes length in our research ...
Corrosion properties of an aluminium alloy 7000 series after a new two step precipitation hardening / Otpornost prema koroziji aluminijumske legure serije 7000 posle novog dvostepenog termičkog taloženja
(Engineering Society for Corrosion, Belgrade, Serbia, 2014)
Corrosion properties of an aluminium alloy 7000 series were investigated by different electrochemical methods. The alloy was subjected to the one-step and to a new two-step precipitation hardening. Polarization measurements ...
Numerical simulation of temperature field in the vertical bridgman method crystal growth
(Savez inženjera metalurgije Srbije, Beograd, 2015)
The mathematical model for heat transfer during the Bridgeman crystal growth, using the finite element method and the obtained result are presented. Some modifications to the method were introduced in order to incorporate ...
Encapsulation of resveratrol in spherical particles of food grade hydrogels / Inkapsulacija resveratrola u sferične čestice na bazi hidrogelova dozvoljenih za upotrebu u hrani
(Institute for Food Technology, Novi Sad, 2017)
The paper reports about the preparation and characterization of hydrogel particles containing liposomes loaded with resveratrol as an active compound. The materials used for preparation of the particles were chosen to be ...
Changes in Pt-Rh catalysts in the working environment
(Institut za rudarstvo i metalurgiju, Bor, 2015)
The surface reconstruction on rhodium-platinum catalyst gauzes has been examined using the scanning electron microscope techniques. The nucleation and growth of large cage-like features, developed on the gauze surfaces ...
Defining the ideality of the protective masks by the mathematical modeling method / Određivanje idealnosti zaštitnih maski metodom matematičkog modelovanja
(University of Belgrade - Faculty of Mechanical Engineering, Belgrade, 2019)
Technical contradiction occurs when the system improves one parameter, which automatically causes the deterioration of some of its other parameters. In such a situation, instead of usual acceptance of the optimization of ...
Properties of cotton yarns after oxidation of potassium permanganate in an acidic environment / Svojstva pamučne pređe posle oksidacije kalijum-permanganatom u kiseloj sredini
(Engineering Society for Corrosion, Belgrade, Serbia, 2017)
The impact of nonselective cellulose oxidation (cotton fibre) by potassium permanganate in acidic environment, with or without additional treatment by sodium metabisulfite, on change of sorption (silver ions sorption), and ...
