Decopperization process of waste solutions from conventional copper electrolysis
(Tatranské Matliare : Slovak Society of Chemical Engineering, 2012)
This paper is adresses on treatment of sulphuric acid waste solutions obtained during the conventional copper metallurgical activities. Mother liquor is a part of this solutions and it is generated during the regeneration ...
CO2 conversion enhancement in a periodically operated Sabatier reactor: Nonlinear frequency response analysis and simulation- based Study
(The 25th International Symposium of Chemical Reaction Engineering (ISCRE 25), Florance, Italy, 2018)
Nonlinear frequency response (NFR) analysis was applied on a Sabatier reactor. A substantial improvement in CO2 conversion was predicted under certain conditions. The NFR analysis prediction was validated using a kinetic ...
Influence of thermal treatment on polyphenolic compounds and antioxidant properties of Quercus robur kernels / Uticaj termičkog tretmana na polifenolne sastojke i antioksidantna svojstva semena lužnjaka, Quercus robur
(Pharmaceutical Association of Serbia, Belgrade, Serbia, 2006)
Polyphenolic compounds and antioxidant properties of dried MeOH extracts of native (QN) and thermally treated (QT) kernels of English Oak, Quercus robur were investigated. The content of total and simple polyphenols and ...
AC Impedance tracking of glassy carbon activation
(Serbian Chemical Society, Belgrade, 2010)
Carbon materials, due to their physical and chemical properties, have found wide application in different electrochemical systems. They are often used as substrates for supercapacitors and different types of electrocatalysts. ...

Testing the applicability of diatom indices for ecological assessment of Balkan lakes
(Taylor & Francis, 2019)
During 2016-2017 six Balkan lakes were investigated: Sava Lake in Serbia, Ohrid Lake and Prespa Lake in North Macedonia and Albania, Great Lake in Albania, Biogradsko Lake and Crno Lake in Montenegro. Epilithic diatom ...
Incorporating a Lowpass Filter into a Very Wide Bandpass Filter to Suppress Harmonics
(Belgrade: ETRAN – Society for electronics, telecommunication, computing, automatics and nuclear angineering, 2021)
This paper presents an algorithm for suppression of higher harmonics in response of the very wide bandpass filter (WBPF). Lowpass filter (LPF) is incorporated into the very wide bandpass filter to suppress harmonics. The ...
Forced Periodic Operation: Effect of shapes for two simultaneously imposed modulations
(German reaction Engineering Meeting (DECHEMA), Wuerzburg, Germany, 2019)
The classical design of continuous chemical reactors exploits steady-state operation, which is optimized and maintained by appropriate control systems. Nevertheless, it is well-known that the reactor performance can be ...
Frequency response analysis as a tool for fast evaluation of periodic operations. Case study: A heterogeneous catalytic reacator
(2nd European Process Intensification Conference (EPIC 2009), Venice, Italy, 2009)
One way to achieve process intensification is to operate the process in a periodic way, in
order to obtain better average performance compared to the optimal steady-state operation.
The source of the possible improvement ...
