Synthesis, characterization and crystal structure of Cu(II) complex with a diimine-dioxime ligand, [Cu-2(LH)(2)](ClO4)(2). Influence of the weak Cu center dot center dot center dot O(perchlorate) interaction on the structure of the Cu2N2O2 metallocycle
(Serbian Chemical Society, 2014)
The diimine dioxime ligand, 3,3'-(1,4-butanediyl-dinitrilo)bis-2-pentanone, 2,2'-dioxime (LH2), containing a N-4 donor set was prepared by the Schiff base condensation of 2-hydroxyimino-3-pentanone and 1,4-diaminobutane ...
Explaining the entropy concept and entropy components
(Serbian Society of Subject Didacticians (SSoSD), 2017)
Total entropy of a thermodynamic system consists of two components: thermal entropy due to energy, and residual entropy due to molecular orientation. In this article, a three-step method for explaining entropy is suggested. ...
Effect of neutralization degree of methacrylic acid on hydrogel swelling and drug release
(The Faculty of Technology, University of Banja Luka, 2022)
Drug delivery system is an amazing tool which is widely used for drugprotection and its controlled release in order to enhance drug bioavailability,reduce side effects and therefore to improve overall therapy. Hydrogels ...
The effect of the presence of alcohol in the dispersing phase of oxide sols on the properties of RuO2-TiO2/Ti anodes obtained by the sol-gel procedure / Uticaj prisustva alkohola u disperznoj sredini oksidnih solova ha osobine RuO2-TiO2/Ti anoda dobijenih sol-gel postupkom
(Serbian Chemical Society, 2000)
The effect of the addition of ethanol and 2-propanol to the dispersing phase of TiO2 and RuO2 sols mixture on the morphology and, consequently, on the electrochemical properties of the sol-gel obtained activated titanium ...
Mechanical properties of composites based on unsaturated polyester resins obtained by chemical recycling of poly(ethylene terephthalate) / Mehanička svojstva kompozita na bazi nezasićenih poliestarskih smola dobijenih hemijskom reciklažom poli(etilen-tereftalata)
(Association of Chemical Engineers of Serbia, 2013)
Composites based on unsaturated polyester (UPe) resins and fumed silica AEROSIL® RY 50, NY 50, RX 50 and NAX 50, as well as graphite, TiO2 or organically modified clay CLOISITE 30B were prepared in order to investigate the ...
A thin layer chromatographic comparison of raw and soluble starch hydrolysis patterns of some alpha-amylases from Bacillus sp isolated in Serbia
(Serbian Chemical Soc, Belgrade, 2014)
Several natural isolates of Bacillus strains namely 5B, 12B, 16B, 18 and 24B were grown at two different temperatures in submerged fermentation for the production of raw-starch-digesting alpha-amylases. All strains except ...
Obtaining Medical Textiles Based on Viscose and Chitosan/Zinc Nanoparticles with Improved Antibacterial Properties by Using a Dielectric Barrier Discharge
(Switzerland : Multidisciplinary Digital Publishing Institute (MDPI), 2022)
This study aimed to obtain functional viscose textiles based on chitosan coatings with improved antibacterial properties and washing durability. For that reason, before functionalization with chitosan/zinc nanoparticles ...
The Effect of Glycol Derivatives on the Properties of Bio-Based Unsaturated Polyesters
(MDPI, 2022)
The scope of the present study was to prepare fully bio-based unsaturated polyester resins (UPRs) with comparable properties to the commercial formulations. The focus was set on the determination of the optimal prepolymer ...
The dispersion-flocculation behaviour of the natural raw clay samples from Omarska mine / Понашање природних узорака глине из рудника Oмарска у процесима дисперзије и флокулације
(Академија наука и умјетности РС, 2019)
In present paper, studied were the dispersion-flocculation behaviour of the primary natural raw „clay samples” from Omarska mine (Republic of Srpska, Bosnia and Herzegovina). Namely, our previous results showed that during ...
Application of Zirconia/Alumina composite oxide ceramics as photocatalysts for removal of 2,4,6-trichlorophenol from water
(MDPI, 2022)
The mesoporous zirconia/alumina composites were synthesized via a sol–gel method,
