Parallel-strip line stub resonator for permittivity characterization
(Niš : University of Niš, 2020)
A new type of a microwave permittivity sensor with a short open stub as a resonator is introduced. The open stub is realized as a double-sided parallel-strip line without a substrate and can be totally immersed into the ...
The influence of chemical composition on microstructure, hardness and electrical conductivity of Ag-Bi-In alloys at 100 degrees C
(Serbia : Association of Metallurgical Engineers of Serbia AMES, 2017)
Considering possible applications and scarceness of literature data, Ag-Bi-In system was investigated in terms of microstructure, mechanical and electrical properties of ternary alloys from an isothermal section at 100 °C. ...

(Belgrade : Association of Metallurgical Engineers of Serbia, 2019)
The investigation here is aimed to examine the structural and mechanical changes that might have occurred during the hot forging process, a process to obtain a surgical hip implant, and the subsequent heat treatment. ...
Testing of intergranular and pitting corrosion in sensitized welded joints of austenitic stainless steel
(Serbia : Association of Metallurgical Engineers of Serbia, 2017)
Pitting corrosion resistance and intergranular corrosion of the austenitic stainless steel X5Cr Ni18-10 were tested on the base metal, heat affected zone and weld metal. Testing of pitting corrosion was performed by the ...
Determination of inorganic anions in herbal tea infusions using ion chromatography / Određivanje neorganskih jona u rastvoru biljnih čajeva jonskom hromatografijom
(Serbia : Matica srpska, 2018)
The ionic content was examined in nine aqueous tea extracts in which time of boiling, acidification of the medium using lemon juice and way of preparation were observed as factors. Ion chromatography was used for determination ...
