Laser treatments of Nimonic 263 nickel-based superalloy / Laserske obrade superlegure Nimonik 263
(Engineering Society for Corrosion, Belgrade, Serbia, 2019)
In this paper, the influence of parameters of laser processing (drilling, cutting, welding and laser shock peening) on microstructure of superalloy Nimonic 263 are investigated. Drilling and welding process are carried out ...
Fluorescence analysis of liposomal membranes permeability / Fluorimetrijska analiza permeabilnosti lipozomalnih membrana
(Savez inženjera i tehničara Srbije, Beograd, 2019)
The present study provides insight into changes in the liposomal membrane fluidity as a result of variation of structural components (two types of standard phospholipids - 1,2-dipalmitoyl-sn-glycerero3-phosphocholine, i.e. ...
Assessment of sampling and chemical analysis of waste printed circuit boards from weee: gold content determination
(Savez inženjera metalurgije Srbije, Beograd, 2019)
Waste printed circuit boards (WPCBs) from discarded mobile phones and smartphones are considerably heterogeneous materials with a high gold content (approx. 490 grams per ton). The aim of our chemical analysis of samples ...
Thermal cycling behaviour of plasma sprayed nicr-al-co-y2o3 bond coat in thermal barrier coating system
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2019)
The aim of this study was to investigate the thermal cycling behaviour of NiCr-Al-Co-Y2O3 bond coating in thermal barrier coating (TBC) system with ZrO2-MgO as a top coating. The coatings were deposited by atmospheric ...
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 ...
The influence of synthesis conditions on the redox behaviour of LiFePO4 in aqueous solution
(Elsevier Science Sa, Lausanne, 2019)
To contribute to the knowledge on the influence of synthesis procedure on the intercalation kinetics of lithium ions into phospho-olivines, LiFePO4/C composite samples (LFPC) were synthesized in two ways, the first one in ...
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 ...
Electrophoretically deposited hydroxyapatite-based composite coatings loaded with silver and gentamicin as antibacterial agents
(Srpsko hemijsko društvo, Beograd, 2019)
Increasing need for improved, compatible bone tissue implants led to the intensive research of novel biomaterials, especially hydroxyapatite (HAP)-based composite materials on titanium and titanium alloy surfaces. Owing ...
Inventive level as a basis for the assessment of scientific contribution of inventors / Inventivni nivo pronalaska kao osnov za procenu naučnog doprinosa pronalazača
(University of Belgrade - Faculty of Mechanical Engineering, Belgrade, 2019)
The history of invention reveals that the most important inventions were derived from experiments by which their authors contributed to the discovery of previously unknown natural phenomena. So the question arises as to ...
