Kinetics of heterogeneous methanolysis of sunflower and used vegetable oil / Kinetika heterogene metanolize svežeg i korišćenog biljnog ulja
(Univerzitet u Beogradu, Tehnološko-metalurški fakultet, 2015)
The synthesis of fatty acid methyl esters (FAME), i.e. biodiesel, in the methanolysis of triglycerides (TG) in the presence of solid catalyst was studied. Heterogeneous catalyst was synthesized by mechanochemical treatment ...
Hemp-based adsorbents for sequestration of metals: a review
(Springer Heidelberg, Heidelberg, 2019)
With the increasing focus on renewable materials and sustainability issues, the development of non-conventional materials from natural resources and possessing complexing properties is currently an area of extensive research ...
Chemico-structural properties and biomineralization of hydroxyapatite coatings produced by high power laminar plasma spray process. / Hemijsko-strukturna svojstva i biomineralizacija hidroksiapatitnih prevlaka dobijenih visokoenergetskim laminarnim plazma sper postupkom
(Univerzitet u Beogradu, Tehnološko-metalurški fakultet, 2016)
In the present work, hydroxyapatite coatings (HACs) were deposited by using the high power laminar plasma spray process. Major objectives were: (i) to estimate effects of several deposition parameters on chemical, structural, ...
Influence of heater temperature and texturing speed on the physical-mechanical properties of polyamide textured yarns in false-twist texturing process
(Inst Natl Cercetare-Dezvoltare Textile Pielarie-Bucuresti, Bucuresti, 2017)
In this paper, the effect of technical and technological parameters in false twist texturing on physical-mechanical properties of polyamide yarns was studied. Partially oriented (POY) multifilament with fineness of 22f07x1 ...
The Potential Ecological Risk Assessment of Heavy Metals in an Urban Shallow Lake
(Skopje : Society of chemists and technologists of Macedonia, 2023)
Urban lakes sediments unfortunately have received a large amount of
wastewater containing various contaminants such as heavy metals (HMs). Heavy
metals in urban lake sediments mainly originate from industrial discharge, ...
Optimization of lindane sorption from aqueous solution by macroporous copolymer using experimental design
(Zvornik : Faculty of Technology, 2023)
In the present study, synthesized macroporous copolymer was used for the sorption of lindane
from an aqueous solution. This organochlorine pesticide is classified, according to US EPA, as
mutagenic and teratogenic. ...
Polyimide structures for micro-electro-mechanical system (mems) - based applications. / Polimidne konzole za primenu u mikro-elektro-mehaničkim (mems) sistemima
(Univerzitet u Beogradu, Tehnološko-metalurški fakultet, 2016)
This Ph.D. thesis studies and experimentally examines applicability of thin polymer films as structural substitutes for crystaline Si in bimorph MEMS structures. The two shapes (bi - morph) and transient state between the ...
Polyhydroxyalkanoate/Antifungal Polyene Formulations with Monomeric Hydroxyalkanoic Acids for Improved Antifungal Efficiency
(Antibiotics, 2021)
Novel biodegradable and biocompatible formulations of "old" but "gold" drugs such as nystatin (Nys) and amphotericin B (AmB) were made using a biopolymer as a matrix. Medium chain length polyhydroxyalkanoates (mcl-PHA) ...
Removal of lindane from aqueous solution by glycidyl methacrylate based chelating macroporous copolymer: kinetics and mechanism
(Banja Luka : University in Banjaluka, Faculty of Technology, 2023)
Lindane belongs to the persistent organic pollutants (POPs) group, which can cause carcinogenic,
endocrine, and neurological problems in an organism. The widespread presence of lindane in the
environment demands efficient ...
Kinetics and thermodynamics of Mo(VI) and Re(VII) sorption on amino-functionalized magnetic polymer
(Belgrade : Society of Physical Chemists of Serbia, 2018)
Kinetics and thermodynamics of Mo(VI) and Re(VII) sorption onto amino
functionalized magnetic poly(glycidyl methacrylate-co-ethylene glycol
dimethacrylate) [mPGME-deta] at 298 K and pH=4.0 were investigated. It
was shown ...
