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. ...
Electrochemical Reduction of Trinitrotoluene on a Modified Platinum Electrode
(Nice : International Society of Electrochemistry, 2010)
Electrochemical reduction of trinitrololuene (TNT) based on the ready reduction of lheir electron-defficient nitro-groups was investigated using platinum electrode in aqueous sodium chloride solutions with acetonitrile ...
High pressure densities of ethylene glycol and caffeine mixtures
(IFP Energies nouvelles, 2021)
Ethylene glycol is a well-known fluid that is recognized for its application in heat transfer processes [1]. In order to improve its characteristics and performances, adding other particles in the mixture of ethylene glycol ...
One-step Synthesis and Characterization of a New Magnetic Polyacrylate Nanocomposite with Aniline
(Academy of Sciences and Arts of the Republic of Srpska, 2020)
In this study, a novel magnetic poly(glycidyl methacrylate-co-trimethylolpropane trimethacrylate)-aniline nanocomposite was synthesized by suspension copolymerization. Firstly, adduct from glycidyl methacrylate and aniline ...

(Belgrade: ETRAN – Society for electronics, telecommunication, computing, automatics and nuclear engineering, 2016)
Tanki bakarni filmovi debljine 10 μm deponovani su na hladno-valjanim supstratima od bakra i mesinga procesom elektrohemijske depozicije iz laboratorijski napravljenog sulfatnog kupatila sa dodatkom različitih aditiva ...
Alumina production from purified Bayer liquor / Proizvodnja glinice iz pročišćene Bayerove otopine
(Hrvatska: Hrvatsko društvo kemijskih inženjera i tehnologa
(HDKI), 2019)
Removal of some impurities from Bayer liquor, such as zinc compounds, allows obtaining alumina with low content of impurities incorporated in the crystalline structure. Impurities in alumina influence the quality of products ...
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 ...
Uklanjanje arsena iz podzemnih voda sa područja Zapadnobačkog okruga / Elimination of Arsenic from the Underground Waters in the Region of West Bačka
(Beograd (Serbia): Udruzenje za tehnologiju vode i sanitarno inzenjerstvo, 2007)
Vojvodina, as a part of Pannonian plain, is supplied with underground waters from well which are located 150 to 200 m under the surface. The quality of these waters is questionable and specific due to to the presence of ...
