Aramid composites impregnated with different reinforcement: Nanofibers, nanoparticles and nanotubes / Aramidni kompoziti impregnisani sa različitim ojačanjima - nanovlakna, nanočestice i nanocevi
(Engineering Society for Corrosion, Belgrade, Serbia, 2014)
In this study, the electrospun nanofibers, nanoparticles and nanotubes were used as reinforcement in order to improve mechanical properties of materials for ballistic protection. The samples of polyurethane/p-aramid ...
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 ...
Hydro- and solvothermally-prepared ZnO and its catalytic effect on the photodegradation of Reactive Orange 16 dye
(Srpsko hemijsko društvo, Beograd, 2014)
In this work, zinc oxide powders were obtained by two different techniques: hydro- and solvothermal synthesis starting from Zn(NO3)(2) and Zn(CH3COO)(2), respectively. The influence of synthetic procedure on the structural, ...
Modification of natural clinoptilolite for nitrate removal from aqueous media
(Srpsko hemijsko društvo, Beograd, 2014)
Natural zeolitic tuff from the Zlatokop mine (Vranjska Banja deposit, Serbia) was investigated as the starting material to obtain a low cost adsorbent for the removal of nitrate from aqueous media. The tuff rich in zeolite, ...
Ballistic Properties of Hybrid Thermoplastic Composites with Silica Nanoparticles
(Inda, Cary, 2014)
Multi-axial aramid fabrics have a wide range of applications in the construction of composite structures for body armor. Nanoparticles, which include nanosilica, are one of the most common nanofillers for these structures. ...
Cryopreservation of cherry rootstock Gisela 5 using vitrification procedure
(Czech Academy of Agricultural Sciences, 2014)
In vitro-grown shoot tips of Gisela 5 (Prunus cerasus x Prunus canescens) cherry rootstock were tested for regrowth after cryopreservation using vitrification technique. Explants were precultured in the dark at 23 degrees ...
Measurement of Sleepers Vibrations and Determination of Their Dynamic Deflection and Train Velocity / Merenje vibracija pružnih pragova i određivanje njihovog dinamičkog ugiba i brzine vozova
(Elektrotehnički fakultet, Istočno Sarajevo, 2014)
A comparative analysis of the selected properties of protective filtering masks / Uporedna analiza odabranih karakteristika zaštitnih maski filtrirajućeg tipa
(Association of Chemical Engineers of Serbia, 2014)
The results of comparative experimental testing of different filtering masks are presented in this study. Some of the most important functional properties have been tested on available models of Italian, French, British, ...
Influence of Synthesis Parameters on Structure of 1-D TiO2 nanostructures
(Belgrade : Serbian Ceramic Society, 2015)
The influence of electrochemical conditions and the heat treatment on the crystal structure and the microstructure evolution of TiO2 based nanotubes synthesized by the self-ordering anodization process is investigated in ...
The influence of novel organic gold complex on photoresist layers of printed circuit boards
(Savez inženjera metalurgije Srbije, Beograd, 2015)
The goal of this paper was to study the influence of organic gold complex based on mercaptotriazole on photoresist layers used in manufacturing of printed circuit boards (PCBs). Investigations were performed by immersion ...
