Cirkularna ekonomija: primena zelene hemije u privrednom sektoru
(Beograd : Univerzitet u Beogradu - Ekonomski fakultet, Centar za izdavačku delatnost, 2023)
U današnjem svetu, suočeni smo sa sve većim izazovima u očuvanju životne sredine i potrebom za održivim razvojem. Koncept cirkularne ekonomije, od teorijskih analiza prešao je i u praktičnu primenu širom Evrope. Međutim, ...
Examples of Wide Microwave Bandpass Microstrip Filters on Felt Substrate
(Belgrade : Institute of Electrical and Electronics Engineers Inc., 2021)
Application of one type of wide bandpass filter on felt (textile) substrate is introduced. Copper tape and conductive textile are used for metallization (conductive layer). It is an initial work. The patterns were done in ...
Numerical evaluation of aerodynamic performances of vertical-axis wind turbine rotor with flow concentrator
(Savez mašinskih i elektrotehničkih inženjera i tehničara Srbije - SMEITS, Beograd, 2020)
With wind energy extraction constantly increasing, the interest in small-scale urban wind turbines
is also expanding. Given that these machines often work in adverse operating conditions
(Earth’s boundary layer, vortex ...
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

Application of essential oil from Achillea millefolium for levan/gelatin blend films
(Book of abstracts of 5th Green and Sustainable Chemistry Conference, 10-11 November 2020, Online, 2020)
Essential oils extracted from plants are attractive additives in the food industry due to their antimicrobial and antioxidant properties. Therefore, in recent years, essential oils have been extensively investigated as ...
Investigation of potential protective effects of microbial levan and pullulan for reducing copper toxicity using Micro-Oxymax respirometer
(Federation of European Microbiological Societies (FEMS), 2020)
This study investigated potential effects of microbial levan and pullulan for reducing copper toxicity in model organism Daphnia magna using Micro-Oxymax respirometer.
Potencijal poljoprivredne biomase u sistemima proizvodnje biogasa u Republici Srbiji / Potential of agricultural biomass in biogas production systems in the Republic of Serbia
(Savez mašinskih i elektrotehničkih inženjera i tehničara Srbije - SMEITS, Beograd, 2020)
Biomasa predstavlja prema zvaničnim podacima najznačajniji potencijal obnovljivih izvora energije u Republici Srbiji. Ona čini oko 63% od ukupnog potencijala, ali za sada njena iskorišćenost nije na zadovoljavajućem nivou. ...
Fractal Reconstruction of Fiber-reinforced Epoxy Microstructure
(Institute of Electrical and Electronics Engineers Inc., 2021)
In the past century, the use of polymers and composites with a polymer matrix has expanded to such a level that today it is impossible to imagine life without these materials. Epoxy resin and epoxy-based composites are ...
Optimization of methanol synthesis under forced dynamic operation
(4th Indo-German Workshop on Advances in Materials, Reaction& Separation Processes, Berlin, Germany, 2020)
Methanol is an essential primary chemical in the chemical industry. Further, there is a
growing interest in using methanol also for chemical energy storage. Excess electrical
wind or solar energy can be converted to ...
Forced periodic reactor operation
(4th Indo-German Workshop on Advances in Materials, Reaction& Separation Processes, Berlin, Germany, 2020)
We used the nonlinear frequency response (NFR) method in order to identify forced periodic conditions under which the acetic acid anhydride hydrolysis (chosen as a test reaction) can be favorably performed in a CSTR. Based ...
