(Book of Abstracts, The 2nd Unifood International Conference-UNIFood Conference 2021, 2021)
The polymerization and crosslinking of various phenolic compounds induced by the laccase enzyme have been in recent years increasingly used in food industry, due to the emergence of products with improved properties, ...
Uklanjanje hroma i olova iz vode korišćenjem otpadnih pređa pamuka i mešavine pamuka i poliestra
(Akademija tehničkih strukovnih studija Beograd, 2021)
U ovom radu je ispitana mogućnost korišćenja otpadnih pamučnih pređa kao adsorbenta
za uklanjanje olova i hroma iz vode, čime bi se obezbedilo ponovno korišćenje tekstilnog otpada i
smanjenje troškova njegovog odlaganja. ...
DEVELOPMENT OF FRUCTOSYLTRANSFERASE NANOBIOCATALYST FOR APPLICATION IN SYNTHESIS OF BIOACTIVE FRUCTO-OLIGOSACCHARIDES
(Faculty of Technology, University of East Sarajevo, 2021)
Fructo-oligosaccharides (FOS) are recognized as prebiotic compounds which have the ability to stimulate the growth of gut microbiota, microorganisms that positively affect human health. Additionally, they have excellent ...

Synthesis and characterization of agar-agar-chitosan composite films incorporated with green synthesized silver nanoparticles
(Proceedings,VII International Congress “ Engineering, Environment and Materials in Process Industry, 2021)
Antimicrobial properties of silver nanoparticles (Ag NPs) are well known and widely exploited. Various approaches have been applied for preparation of Ag NPs. Nowadays, „green“ methods are attracting more attention since ...
Solid-phase extraction of estrogen hormones from water using multi-walled carbon nanotubes as sorbent
(Society of Physical Chemists of Serbia, 2021)
Multi-walled carbon nanotubes were employed as a sorbent for solid-phase extraction of estrogen hormones (estrone, 17β-estradiol, and 17α-ethinylestradiol) from water solution. The solid-phase extraction (SPE) method was ...
Removal of arsenic(III) oxyanions from wastewater using aminosilane -modified natural and synthetic zeolite
(Croatia : Croatian Zeolites Association, 2021)
Silanization of the natural and synthetic zeolites as well as their use as adsorbents for removing arsenic(III) oxyanions from wastewater are the topic of this paper. Two types of zeolite were used: natural zeolite-clinoptilolite ...
Phoenix spectra for determination of the fundamental stellar parameters
(Institute of Physics, Belgrade, SerbiaAstronomical Observatory Belgrade, Serbia, 2021)
We present a set of calculated spectra for stellar atmospheres. Temperature is
varied from 2500-10000K, log g from 0.5 to 5.5, z from 0.5 to 2.5 and alpha
enhancement -0.2 to +0.8. Our aim is to use these spectra as ...
Synthesis and biological evaluation of some azo dyes based on 3-cyano-6-hydroxy-4-methyl-1-propyl-2-pyridone / Sinteza i biološka svojstva nekih azo boja na bazi 3-cijano-6-hidroksi-4-metil-1-propil-2-piridona
(Beograd : Savez mašinskih i elektrotehničkih inženjera i tehničara Srbije (SMEITS), Društvo za procesnu tehniku, 2021)
Azo dyes are the most important group of organic synthetic dyes. High molar extinction coefficients, which characterize azo compounds, contribute to their wide use in traditional dyeing of various materials, as well as the ...
