Superkritična ekstrakcija kao metoda za uklanjanje pesticida iz zemljišta
(Univerzitet u Kragujevcu, Agronomski fakultet u Čačku, 2016)
Cilj ovog rada je ukazivanje na mogućnost primene superkritične ekstrakcije sa ugljendioksidom na dekontaminaciju zemljišta zagađenih pesticidima (u ovom slučaju atrazinom). Analizirani rezultati ukazuju da se ova metoda ...
Customization of evanescent near fields on freestanding plasmonic nanomembranes
(Belgrade: ETRAN – Society for electronics, telecommunication, computing, automatics and nuclear engineering, 2018)
For a very long time optical evanescent near fields have been considered useless for practical applications and remained a theoretical curiosity. However, with advances in micro and nanotechnologies and the decreasing sizes ...

Morphology, structure and hardness of electrolytically produced copper coatings
(Sarajevo : Faculty of Science University of Sarajevo, 2022)
Influence of various parameters of electrodeposition, such as type of cathode, composition of the electrolyte and thickness of the coating, on morphology, structure and hardness of copper coatings has been investigated.
Printed Antenna Arrays with Cylindrical Parabolic Reflector
(20th Telecommunications Forum, TELFOR 2012 - Proceedings, 2012)
Concept of design and realization of high gain printed antenna structures is presented. They consist of antenna array, subreflector, feeding network and bal-un, all printed on the same dielectric substrate. Linear array ...
Analyse of One Type of Resonant Cell
(9th International Conference on Telecommunications in Modern Satellite, Cable, and Broadcasting Serv, 2009)
Analyse of one type of resonant cell is proposed. One to three cells are combined into a low pass filter. The filter design curves for various substrates and cut off frequencies are presented.
New Modified Microstrip Bandstop Filter with Only One (First Order) Bandstop
(9th International Conference on Telecommunications in Modern Satellite, Cable, and Broadcasting Serv, 2009)
In this paper, a new structure with only one (first order) bandstop is reported. A simple trapezoid shape of the microstrip line is introduced instead of the more complicated pattern. It obtains simple simulation, optimization ...
Fluorination as a Driving Force in Crystal Structures
(Commission on Quantum Crystallography of IUCr, 2020)
The results of the crystallographic analysis in combination with quantum chemical calculations have
shown that fluorination of organic compounds causes an increase in the proton-donating ability and a
decrease in the ...
Vacuum Sensing Based on the Influence of Gas Pressure on Thermal Time Constant
(Institute of Electrical and Electronics Engineers Inc., 2014)
In this paper we propose a novel operating principle for thermal vacuum sensor. The sensor considered in this work consists of thermopiles and thermally isolating membrane structure. The operating principle of such sensor ...
Wind turbine beyond 20 MW – Technology perspective
(Savez mašinskih i elektrotehničkih inženjera i tehničara Srbije - SMEITS, Beograd, 2020)
The trend of wind turbine development has a special significance in the exploitation of renewable
energy sources. At higher altitudes, we have better wind energy utilization higher speed and
their conversion are achieved ...
