Corrosion properties of an aluminium alloy 7000 series after a new two step precipitation hardening / Otpornost prema koroziji aluminijumske legure serije 7000 posle novog dvostepenog termičkog taloženja
(Engineering Society for Corrosion, Belgrade, Serbia, 2014)
Corrosion properties of an aluminium alloy 7000 series were investigated by different electrochemical methods. The alloy was subjected to the one-step and to a new two-step precipitation hardening. Polarization measurements ...
Contributions of impregnated silver nanoparticles to ideality increase of filtration material in human respiratory protection / Doprinos impregnisanih nanočestica srebra porastu idealnosti filtrirajućih sredstava respiratorne zaštite
(Engineering Society for Corrosion, Belgrade, Serbia, 2019)
A technical contradiction arises when within a system one parameter improves thus automatically causing another one to worsen. In a situation like this, instead of a usual acceptance of compromise which leads to optimization ...
Effect of AL2O3 particles on the toughness of hybrid composite with EVA matrix and UHMWPE fibersas reinforcement / Uticaj AL2O3 čestica na žilavost hibridnog kompozita sa EVA matricom ojačanog UHMWPE vlaknima
(Savez inženjera i tehničara Srbije, Beograd, 2018)
The aim of this paper is to investigate the mechanical properties of hybrid composites with the polymer matrix of the copolymer of ethylene and vinyl acetate (EVA), ultra high molecular weight polyethylene fibers (UHMWPE) ...
Optimization of the process of calcium-carbonate dispersion stabilization for paper industry needs / Proces dobijanja stabilne disperzije kalcijum-karbonata za potrebe papirne industije
(Savez inženjera i tehničara Srbije, Beograd, 2018)
This paper presents the optimized technological process for obtaining stable calcium carbonate dispersion (CaCO3) in accordance to the standard prescribed in the paper industry. The reason for using CaCO3 in paper production ...
Cracking caused by cutting of plasma-sprayed hydroxyapatite coatings and its relation to the structural features of coatings deposited at different initial substrate temperatures
(Savez hemijskih inženjera, Beograd, 2017)
The present study estimated the cracking phenomenon in as-plasma-sprayed hydroxylapatite coatings (HACs) after they were being subjected to the severe cutting conditions in the direction perpendicular to the coating/substrate ...
Ag+, Cu2+ and Zn2+ doped hydroxyapatite/tricalcium phosphate bioceramics: Influence of doping and sintering technique on mechanical properties
(University of Novi Sad, Faculty of Technology, 2018)
Green hydroxyapatite ceramics were obtained by cold uniaxial and isostatic pressing of hydrothermally synthesized powders, pure hydroxyapatite and hydroxyapatite doped with Ag+, Cu2+ and Zn2+ ions. The ceramics were ...
Supercritical co2 impregnation of gelatin-chitosan films with clove essential oil and characterization thereof
(Savez hemijskih inženjera, Beograd, 2019)
Supercritical CO2 impregnation process was used for the first time to fabricate biodegradable gelatin-chitosan (G/Ch) films containing dove oil (CO) for potential use in active food packaging. All the impregnations were ...
Synthesis and properties of nano-hydroxyapatite/poly (methacrylic acid) composite hydrogels / Uticaj neutralizacije na svojstva poroznih hidrogelova na bazi hidroksiapatita i poli(metakrilne kiseline) sintetisanih slobodno-radikalskom polimerizacijom
(Savez inženjera i tehničara Srbije, Beograd, 2018)
Goals. The goal of this study was a development of biocompatible composite hydrogels, structurally similar to native bone tissue, by incorporation of ~60 wt % of calcium hydroxyapatite (HA) into a matrix of hydrogels. Also, ...
β-amylase production by a novel strain Paenibacillus chitinolyticus CKS1 using commercial and waste substrates / Proizvodnja β-amilaza pomoću novog bakterijskog soja Paenibacillus chitinolyticus CKS1 na komercijalnim i otpadnim supstratima
