Analysis of the effects of butt welded joints on a carrying capacity of a structure tank / Analiza uticaja sučeono zavarenih spojeva na nosivost konstrukcije rezervoara
(Engineering Society for Corrosion, Belgrade, Serbia, 2017)
In the present paper, after calculation using the Finite Element Method (FEM), stress distribution on the model of a part of the pressure-tank mantle without welded joints (WJ), with transversal WJ, longitudinal WJ and ...
Enhanced sorption of Cu2+ from sulfate solutions onto modified electric arc furnace slag
(Elsevier Science Bv, Amsterdam, 2019)
Pristine electric arc furnace slag (EAFS) as well as EAFS modified by alkali activation i.e. alkali activated slag (AAS) have found a novel application as adsorbents used in Cu2+ removal from sulfate solutions. The adsorption ...
Behaviour of nionikral-70 in low-cycle fatigue
(Society for Structural Integrity and Life, Institute for Material Testing, 2017)
Experimental research on the behaviour of high-strength low-alloy steel ( HSLA)exposed to low-cycle fatigue (LCF) with controlled and fully reversible strain (Delta epsilon/2 = const, R epsilon =epsilon(min)/epsilon(max) ...
The Study of the Enzymatic Synthesis Mechanism of 4,6-Disubstituted 3-cyano-2-pyridones / Proučavanje mehanizma enzimske sinteze 4,6-disupstituisanih-3-cijano-2-piridona
(Univerzitet u Beogradu, Tehnološko-metalurški fakultet, 2013)
In this thesis, the mechanism of lipase catalyzed synthesis of 4,6-disubstituted-3-cyano-2-pyridones was studied, and for that purpose the simplest molecule, 4,6-dimethyl-3-cyano-2-pyridone, and vitamin B6 precursor, ...
Preparation of nanocomposites based on thermoplastic polymers and influence of titanium and iron oxides nanoparticles on their properties / Dobijanje nanokompozita na bazi termoplastičnih polimera i uticaj nanočestica oksida titana i gvožđa na njihova svojstva
(Univerzitet u Beogradu, Tehnološko-metalurški fakultet, 2010)
The synthesis of polymer nanocomposites by in situ polymerization of monomers in the presence of filler particles is presented in this dissertation. Nanoparticles of TiO2 and α-Fe2O3 were used as fillers. Polymer nanocomposites ...
N-(substituted phenyl)-2-chloroacetamides: LSER and LFER study
(Elsevier, Amsterdam, 2019)
The UV absorption spectra of twelve N-(substituted phenyl)-2-chloroacetamides were recorded in eighteen solvents. The effect of specific and non-specific solvent-solute interactions on the absorption maxima shifts was ...
Solvatochromism of isatin based Schiff bases: An LSER and LFER study
(Srpsko hemijsko društvo, Beograd, 2016)
The derivatives of isatin (1H-indole-2,3-dione) have already been reported to show a variety of biological activities. However, there have hitherto been no reports on the solvatochromic effects of isatin derivatives, and ...
Removal of heavy metals from water using multistage functionalized multiwall carbon nanotubes
(Srpsko hemijsko društvo, Beograd, 2017)
The multistage synthesis of the multi-wall carbon nanotubes (MWCNT) modified with polyamidoamine dendrimers, A1/and A2/MWCNT, capable of cation removal, is presented in this work, as well as novel adsorbents based on these ...
Washing and Desinfection of the Wells Type Reni / Hiperdezinfekcija bunara za vodosnabdevanje tipa Reni
