Pyro-Refining of Mechanically Treated Waste Printed Circuit Boards in a DC Arc-Furnace
(Springer, New York, 2018)
This paper presents the results of theoretical assessment and a preliminary experimental investigation of the modified pyrometallurgical processing of metallic granulate obtained after mechanical treatment of waste printed ...
Adsorption performances of branched aminated waste polyacrylonitrile fibers: experimental versus modelling study
(Desalination Publ, Hopkinton, 2019)
Synthesis of branched aminated waste polyacrylonitrile (PAN) fibers, realized in a three addition/amidation successive steps, was performed in order to obtain AS3-PAN adsorbent. Influence of various operating parameters ...
A survey on the characterization and biological activity of isatin derivatives
(Srpsko hemijsko društvo, Beograd, 2020)
The derivatives of isatin have already been known to display a variety of biological activities. Therefore, the studies on their activity and its relation to structure have recently become a popular subject for investigation. ...
Poly(vinyl alcohol)/chitosan hydrogels with electrochemically synthesized silver nanoparticles for wound dressing applications
(Int Assoc Physical Chemists-Iapc, Zagreb, 2020)
Polymer-based hydrogel materials are excellent candidates for new-generation wound dressings with improved properties, such as high sorption ability, good mechanical properties and low adhesiveness. Cross-linked hydrogel ...
Ethanol Thymus serpyllum extracts: Evaluation of extraction conditions via total polyphenol content and radical scavenging activity
(Institute for Medicinal Plants Research "Dr. Josif Pancic", 2019)
The aim of the present study was the optimization of the extraction conditions (particle size, solid-to-solvent ratio, extraction time and procedure) via total polyphenol content and radical scavenging activity, using wild ...
Treatment of the acidic effluent from a copper smelter by flotation tailings
(Savez hemijskih inženjera, Beograd, 2019)
Since commissioning in 1961, the copper mine Majdanpek, a part of the Mining and Smelting Complex Bor (RTB Bor), produced approximately 378 million tons of flotation tailings. Semiquantitative mineralogical analysis of the ...

Adsorptive, catalytic and antimicrobial applications of Serbian natural clinoptilolite
(Lublin University of Technology, Nadbystrzycka 40 20-618 Lublin, 2018)
Clinoptilolite is the most abundant natural zeolite in Serbia, and the Zlatokop deposit (near Vranjska Banja) is the largest deposit. The zeolitic tuff (CT) from Zlatokop contains >70 wt. % clinoptilolite with quartz and ...
Processing of Data Obtained by the Testing of Steel under Low Cyclic Fatigue (Part I)
(University of Zagreb Faculty of Mechanical Engineering and Naval Architecture, 2022)
The design of mechanical components exposed to fatigue load, at a low number of cycles, requires knowledge of the behaviour of the material under the impact of variable load in conditions of controlled strain when cyclic ...
"Do-It-Yourself" reliable pH-stat device by using open-source software, inexpensive hardware and available laboratory equipment
(Public Library Science, San Francisco, 2018)
In this paper, we present the construction of a reliable and inexpensive pH stat device, by using open-source "OpenPhControl" software, inexpensive hardware (a peristaltic and a syringe pump, Arduino, a step motor...), ...
