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 ...
Lactic acid production from corn cob
(Nacionalno društvo za procesnu tehniku i energetiku u poljoprivredi, Novi Sad, 2021)
Over the past decade, a growing interest in bio-based plastics, such as poly-lactic acid, encouraged the production of lactic acid from second-generation feedstocks. Being wide available, low-cost, and renewable, lignocellulosic ...
Lactic acid bacteria: From food preservation to active packaging
(IOP Publishing Ltd, 2021)
Lactic acid bacteria (LAB) have acted in food fermentations through the ages due to their safety and resilience to specific harsh conditions of high salinity or low pH present in food and gut where they live. Their interaction ...
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 ...
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 ...
Development of innovative liposome-release systems for encapsulation of biologically active soybean peptides
(Belgrade : University of Belgrade, 2021)
Bioactive peptides constituents of protein hydrolysates show great instability, poor absorption and bitterness when incorporated into food formulations. In addition, in the gastrointestinal system, there has been noted a ...
Analiza estrogenih hormona iz uzoraka površinskih, podzemnih i otpadnih voda
(Akademija tehničkih strukovnih studija Beograd, 2021)
Prisustvo estrogenih hormona u vodenim ekosistemima posledica je ispuštanja
neprečišćenih otpadnih komunalnih voda, kao i nemogućnost potpunog uklanjanja estrogenih
hormona u postrojenjima za prečišćavanje otpadnih voda. ...
Uklanjanje jona olova korišćenjem ugljeničnih adsorbenata na bazi pamučnih pređa uticaj parametara dobijanja i sastava polazne sirovine na adsorpcione karakteristike
(Akademija tehničkih strukovnih studija Beograd, 2021)
Pređe pamuka i mešavine pamuka i poliestra, dobijene kao otpad iz tekstilne industrije,
korišćene su kao jeftina i lako dostupna polazna sirovina za dobijanje ugljeničnih adsorbenata.
Ugljenični materijali dobijeni su ...
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 ...
