Structure and Microstructure Characterization of the La2SrB10O19 Glass-ceramics
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2019)
The crystal structure of new lanthanum strontium borate glass-ceramics was refined by the Rietveld method. The results showed that La2SrB10O19 has the monoclinic crystal structure, space group C2 (No. 5) with a = 11.1170(6), ...
Solvatochromism and azo-hydrazo tautomerism of novel arylazo pyridone dyes: Experimental and quantum chemical study
(Elsevier, Amsterdam, 2019)
The state of the tautomeric equilibria of eleven arylazo pyridone dyes was evaluated from UV-Vis absorption spectra with the aid of the quantum mechanical modeling. NMR analysis and theoretical calculations, by using ...
On the synthesis of 3-cyano-6-hydroxy-4-methyl-2-pyridone at room temperature / O sintezi 3-cijano-6-hidroksi-4-metil-2-piridona na sobnoj temperaturi
(Engineering Society for Corrosion, Belgrade, Serbia, 2019)
Milling of cyanoacetamide and acetoacetic ester as reactants, in the presence of KOH as the catalyst and ethanol as a viscous control agent (VCA) was performed in a planetary ball mill with the goal of investigating the ...
Cleaning and Desinfection a Part of Water Suplly System Ušće Zemun – Piramida New Belgrade / Pranje i dezinfekcija vodovodne mreže na relaciji Ušće Zemun – Piramida Novi Beograd
(Čačak : Univerzitet u Kragujevcu, Agronomski fakultet, 2019)
It was noticed worldwide that nutrient enrichment and climatic change as global warming and hydrologic changes with periods of more intense droughts strongly affect cyanobacterial growth. Toxigenic cyanobacteria that can ...
Leaching kinetics of Cs+ and Co2+ under dynamic conditions
(Nuclear Technology and Radiation Protection, 2019)
The possibility of retaining Cs+ and Co2+ bound by immobilization processes in the cement matrix is defined as the subject of its investigation: the cement matrix formulation, the water/ cement ratio, the amount of waste, ...
Mechanical characterization of copper coatings electrodeposited onto different substrates with and without ultrasound assistance
(Srpsko hemijsko društvo, Beograd, 2019)
The mechanical properties of systems consisting of copper coatings electrodeposited on both brass sheet (BS) and thick electrodeposited nickel coating (ED Ni) substrates have been investigated. The electrodeposition of ...
Electrochemical stability of metformin in NaHCO3 and Na2SO4 water solution at Au, GC and IrOx electrodes
(Srpsko hemijsko društvo, Beograd, 2019)
In this study the electrochemical behavior of metformin (MET), oral antihyperglycaemic agent, was assayed at three different electrodes. The drug standard was investigated by cyclic voltammetry and square wave voltammetry ...
Solutions of ionic liquids with diverse aliphatic and aromatic solutes - Phase behavior and potentials for applications: A review article
(Elsevier, Amsterdam, 2019)
This article principally reviews our research related to liquid-liquid and solid-liquid phase behavior of imidazolium- and phosphonium-based ionic liquids, mainly having bistriflamide ([NTf2](-)) or triflate ([OTf](-)) ...
Washing and Desinfection of the Wells Type Reni / Hiperdezinfekcija bunara za vodosnabdevanje tipa Reni
(Čačak : Univerzitet u Kragujevcu, Agronomski fakultet, 2019)
We show in this work the treatment procedure utilized for cleaning and desnfection of water in water wells of large capacity as in the case of wells of Belgrade Waterworks. The typical examples of such well of large capacity ...
Theoretical and experimental investigation of geometry and stability of small potassium-iodide KnI (n=2-6) clusters
(Wiley, Hoboken, 2019)
Small heterogeneous potassium-iodide clusters are investigated by means of ab initio electronic structural methods together with experimental production and detection in mass spectrometry. Experiments were done by using ...
