Fracture analysis of axially flawed ring-shaped bending specimen
(Elsevier Science Bv, Amsterdam, 2018)
Application of pipelines is common in process industry and energetic facilities, as parts of storage and transport systems. Structural integrity and fracture resistance of the pipeline elements is typically assessed by ...
Uticaj oksidacije na strukturu i površinsko naelektrisanje pamučne pređe / Influence of oxidation on the structure and surface charge of cotton yarn
(Beograd : Srpsko hemijsko društvo, 2019)
In this work, an influence of oxidation with potassium
permanganate (KMnO4) of different concentration, on the structure,
sorption properties and surface charge of cotton yarn was investigated.
Cotton oxidation was ...
Microstructural morphology effects on fracture resistance and crack tip strain distribution in Ti-6Al-4V alloy for orthopedic implants
(Elsevier Sci Ltd, Oxford, 2014)
The effects of microstructural morphology on the fracture behavior of Ti-6Al-4V ELI (extra-low impurity) alloy in two different heat treatment conditions were examined. Alloy was solution treated above (beta ST) and below ...
PMMA-Y2O3 (Eu3+) nanocomposites: Optical and mechanical properties / Nanokompozit PMMA-Y2O3 (Eu3+) - optička i mehanička svojstva
(Serbian Chemical Society, Belgrade, 2011)
The results of a study related to the processing and characterization of poly(methyl methacrylate) (PMMA)-Y2O3 (Eu3+) nanocomposites are presented herein. The nanocomposite samples were prepared using a laboratory mixing ...
Impact of the poly(propylene oxide)-b-poly(dimethylsiloxane)-b-poly-(propylene oxide) macrodiols on the surface-related properties of polyurethane copolymers
(Assoc Chemical Engineers Serbia, Belgrade, 2016)
Segmented thermoplastic polyurethane copolymers (PURs) were synthesized using 4,4'-methylenediphenyl diisocyanate and 1,4-butanediol as the hard segment and alpha,omega-dihydroxy-poly(propylene oxide)-b-poly(dimethylsilo ...
Determination of the Load Carrying Capacity of Damaged Pipes Using Local Approach to Fracture
(Japan Inst Metals, Sendai, 2012)
The subject of this study was the application of local approach to ductile fracture in order to estimate the integrity of damaged seam casing pipes for oil and gas drilling rigs. The experimental testing included tensile ...
Biocompatibility and antimicrobial activity of zinc(II)-doped hydroxyapatite, synthesized by a hydrothermal method / Biokompatibilnost i antimikrobna aktivnost hidroksiapatita sa ugrađenim cinkom sintetisanog hidrotermalnom metodom
(Serbian Chemical Society, Belgrade, 2012)
In order to obtain multifunctional materials with good biocompatibility and antimicrobial effect, hydroxyapatite (HAp) doped with Zn2+ was synthesized by a hydrothermal method. Powders with different content of zinc ions ...
ZnO nanopowders obtained by thermolysis of zinc benzenedicarboxylate complexes with 2,2’-dipyridylamine
(Belgrade : Institute for Multidisciplinary Research, University, 2017)
Coordination chemistry provides the know-how for the synthesis of the
precursor compounds with variable composition and structures, while the thermal
induced changes may control the crystalline structure, phase ...

(Savez inženjera i tehničara Srbije, Beograd, 2015)
Besides iron ore, the main raw material of iron and steel production is steel scrap. This paper presents the quality and sources of creation the iron and steel scrap and estimation of their creation in the future. The ...
Supercritical extraction of essential oil from Mentha and mathematical modelling- the influence of plant particle size
(Elsevier Science Bv, Amsterdam, 2012)
Supercritical CO2 extraction was studied using dried leaves of Mentha, originated from the northern part of Libya. Leaves were milled and sieved to obtain different average particles (d(p) = 0.25 - 0.80 mm). They were ...
