Precipitation behaviour in pH adjusted lateritic ore solution
(Belgrade : Serbian Society of Corrosion and Materials Protection (UISKOZAM), 2021)
Hydrometallurgical procedure and chemical measurements were employed to study the precipitation behavior of different metals in a lateritic ore pregnant leach solution (PLS). Lateritic ore was leached in 1 M H2SO4 solution ...
Influence of electrolyte type and agitation regimes on structural- mechanical performance of electrolytically deposited copper coatings on different cathodes
(Beograd : Vojnotehnički institut / Belgrade : Military Technical Institute, 2022)
Composite systems of electrodeposited 10 µm Cu coatings on Cu foils and 30 µm Cu coatings on brass foils were obtained in direct current regimes (DC) from electrolytes without/with additives. Different regimes of stirring ...
Chemical composition of Origanum dictamnus and Origanum vulgare ssp. hirtum from Greece
(Faculty of Architecture – University of MontenegroFaculty of Philosophy - University of MontenegroBiotecnical faculty - University of Montenegro, 2020)
Most of the Origanum species are locally distributed within the Mediterranean region
where they grow in the mountainous areas on the islands. Due to this, the rate of endemism is high,
as in case of dittany of Crete (O. ...
Photovoltaics of sol-gel processed titanium oxide coating
(Serbian Chemical Society, Belgrade, 2010)
Titanium oxide is applied as a photocatalyst in organic synthesis and for waste water treatment and outdoor air purification. In this work, photoelectrochemical (PEC) activity of titanium oxide coating on titanium substrate, ...
Effect of neutralization degree of methacrylic acid on hydrogel swelling and drug release
(Banja Luka : University in Banjaluka, Faculty of Technology, 2022)
Drug delivery system is an amazing tool which is widely used for drug protection and its controlled
release in order to enhance drug bioavailability, reduce side effects and therefore to improve overall
therapy. Hydrogels ...
Biobased unsaturated polyester resins reinforced with natural fillers
(Banja Luka : University in Banjaluka, Faculty of Technology, 2022)
Most used raw materials for production of unsaturated polyester resins are obtained from
petroleum. Transitioning to biobased unsaturated polyester resins is a complex, costly and time consuming process, but it is necessary ...
Synthesis and characterization of azido Zn(II) complex with the condensation product of 2-acetylthiazole and thiosemicarbazide / Синтеза и карактеризација азидо комплекса Zn(II) са кондензaционим производом 2-ацетилтиазола и тиосемикарбазида
(Belgrade, Serbia : Serbian Cristallographic Soceity // Beograd, Srbija : Srpsko kristalografsko društvo, 2023)
The ligand (E)-2-(1-(thiazol-2-yl)ethylidene)hydrazine-1-carbothioamide (HL) was obtained from the condensation of 2-acetylthiazole and thiosemicarbazide. Upon reacting HL with Zn(BF4)2.6H20 and NaN3 in a solvent mixture ...
Monitoring of Krivelj river collector deformation
(Skopje : Society of chemists and technologists of Macedonia, 2016)
Study of monitoring and analyzing the deformation of the collector Krivelj River has been developed. In the period May-July 2009, the recording of the measurements and the state of the crack deformation in reinforced ...
The behavior of cerium doped phosphate tungsten bronze in Briggs-Rauscher oscillatory reaction
(Serbian Ceramic Society, 2022)
The Briggs-Rauscher (BR) reaction is an oscillating reaction in which the oxidation of malonic acid (CH2(COOH)2) in the presence of hydrogen peroxide (H2O2) and potassium iodate (KIO3) is catalyzed with a metal ion (usually ...
Biobased composite materials obtained from unsaturated polyester resins and waste coffee / Kompozitni materijali na bazi nezasićenih poliestarskih smola dobijenih iz bioobnovljivih izvora i otpadne kafe
(Savez mašinskih i elektrotehničkih inženjera i tehničara Srbije (SMEITS)Društvo za procesnu tehniku, 2022)
Replacing styrene with biobased monomers to produce fully biobased unsaturated polyester
resins (UPRs) turned out to be quite a challenging task. Styrene has been recognized as a hazardous and a potentially carcinogenic ...
