Synthesis, Structure and Properties of Nickel-Iron-Tungsten Alloy Electrodeposits PART II: Effect of Microstructure on Hardness, Electrical and Magnetic Properties
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2016)
Nanostructured nickel-iron-tungsten alloys were produced by electrodeposition from an ammoniacal citrate bath. The tungsten content of the alloy ranged from 0.8 wt.% to 11 wt.%, and the crystal grain size of the FCC phase ...
Corrosion of Archaelogical Artefact made of Forged Iron
(Savez inženjera matalurgije Srbije, Kneza Miloša 9, 11000 Beograd, 2012)
One artefact of the archaeological cultural heritage from Roman period (IV century) that was
found near Šabac in Serbia, was analysed. In corrosion products of the artefact (knife),
dominant phases were goethite (α-FeOOH) ...
Effects of oxidized/treated non-metallic fillers obtained from waste printed circuit boards on mechanical properties and shrinkage of unsaturated polyester-based composites
(Wiley, Hoboken, 2019)
The investigation of the influence of acid/base treatment and addition level of non-metallic fractions (NMFs), obtained by processing of printed circuit boards, on the mechanical properties and shrinkage of unsaturated ...
Substituent Effects on the Patterns of Intermolecular Interactions of 3-Alkyl and 3-Cycloalkyl Derivatives of Phenytoin: A Crystallographic and Quantum-Chemical Study
(American Chemical Society (ACS), 2019)
A series of five derivatives of the anticonvulsant drug phenytoin was synthesized, and their crystal structures were determined. The relationship between the molecular and crystal structure of the investigated compounds ...
Antibacterial activity of metal-containing clinoptilolite in natural seawater
(Desalination Publ, Hopkinton, 2019)
Antibacterial activity of a natural zeolite, clinoptilolite (Z), enriched with about 0.4-0.5 mmol of Ag (Ag-Z), Cu (Cu-Z) or Zn (Zn-Z) was tested toward two strains of Gram-negative bacteria - Escherichia coli and Acinetobacter ...

On the azo dyes derived from benzoic and cinnamic acids used as photosensitizers in dye-sensitized solar cells
(Scientific Technical Research Council Turkey-Tubitak, Ankara, 2019)
In order to get a better insight into the relationship between molecular structure and photovoltaic performance, six monoazo dye molecules containing benzoic and cinnamic acid moieties were synthesized and their photovoltaic ...
Examination of mechanical properties of acrilyc composite materials with different AL2O3 reinforcement by brazil test / Ispitivanje mehaničkih svojstava akrilatnih kompozitnih materijala sa različitim AL2O3 ojačanjima brazilskim testom
(Savez inženjera i tehničara Srbije, Beograd, 2019)
Composite materials based on UV-curing acrylates and various alumina-based reinforcements represent material that is suitable for the use in dentistry, but also in other areas. Composites were made using four different ...
Continuous flow synthesis of some 6-and 1,6-substituted 3-cyano-4-methyl-2-pyridones
(Srpsko hemijsko društvo, Beograd, 2019)
In this study, six 6- and 1,6-substituted-3-cyano-4-methyl-2-pyridones were synthesized in a continuous flow microreactor system. The syntheses were realized at room temperature and the obtained results were compared to ...
