Properties of adsorbent obtained by conventional and under microwave irradiation / Svojstva adsorbensa dobijenog aktivacijom bentonita na konvencionalan način i u mikrotalasnom polju
(Savez inženjera i tehničara Srbije, 2012)
In this paper the effect of acid activation by conventional and under microwave irradiation on the textural and structural properties of bentonite was studied. The adsorbents were characterized by powder X-ray diffraction ...
The analysis of forming PVB-SiO2 nanocomposite fibers by the electrospinning process / Analiza formiranja PVB-SiO2 nanokompozitnih vlakana pomoću elektrospining procesa
(Vojnotehnički institut, Beograd, 2011)
The poly (vinyl butyral)-silica (PVB-SiO2) nanofibers were obtained by the electrospinning process. The experiments were carried out with PVB solution in concentration of 10 wt.% where ethanol was used as the solvent. The ...
Antitumour effect of a mixture of n-propyl polysulfides In vitro / Antitumorski efekti smeše n-propil polisulfida in vitro
(Serbian Journal of Experimental and Clinical Research, 2019)
Copper serves as a limiting factor for multiple steps of tumour progression, including angiogenesis, growth and metastasis. High levels of copper have been found in a wide spectrum of human cancers. Antitumour activities ...
Reationship between corrosion potential and diferent corrosion forms of metals, alloys and theirs welded joints: Part I / Veza izmenu korozionog potencijala i različitih vidova korozije metala, legura i njihovih zavarenih spojeva - deo I
(DUZS - Društvo za unapređivanje zavarivanja u Srbiji, Beograd, 2017)
This paper briefly describes the relationship between corrosion potential and different corrosion forms of metals and their welded joints. The nature of corrosion potential and the method of its measurement is also described. ...
Pitting corrosion testing of stainless steel AISI 304 in chloride solutions / Ispitivanje piting korozije nerđajućeg čelika AISI 304 u rastvorima hlorida
(DUZS - Društvo za unapređivanje zavarivanja u Srbiji, Beograd, 2015)
Stainless steels and their welded joints are often susceptible to pitting corrosion in solutions containing chloride ions. Testing of pitting corrosion of stainless steels is performed using chemical and electrochemical ...
Aromatic π-networks in Sm/LSm protein interfaces / Aromatična π-mreža u interfejsima Sm/LSm proteina
(Univerzitet u Nišu, 2014)
In this work, we have analyzed the influence of π-π interactions on stability and properties of Sm/LSm assemblies. The residues were found to be involved in π-π interactions much more frequently than Tyr or His. Similarly, ...
Determination of ionization constants (PKA) of β-hydroxy-β-arylalkanoic acids using high-pressure liquid chromatography
(University of Kragujevac, Faculty of Science, 2018)
pKa values of five β-hydroxy-β-arylalkanoic acids and ibuprofen were determined using the RP-HPLC method. Stationary phase was octadecyl modified (C-18) silica gel, and mobile phase was a mixture of methanol and one of ...
