Synthesis of Silica Particles Using Ultrasonic Spray Pyrolysis Method
(Metals, 2021)
Silica has sparked strong interest in hydrometallurgy, catalysis, the cement industry, and paper coating. The synthesis of silica particles was performed at 900 degrees C using the ultrasonic spray pyrolysis (USP) method. ...
Optimization of modifier deposition on the alumina surface to enhance mechanical properties and cavitation resistance
(Springer, New York, 2020)
Composites based on poly(methyl methacrylate), dimethyl itaconate matrix and alumina particles were prepared. Ferrous oxide-doped alumina particles (Al2O3Fe) and commercial alumina nanoparticles (Al(2)O(3)n) modified with ...
Principal component analysis of morphological descriptors for monitoring surface defects induced by thermal shock
(Journal of the European Ceramic Society, 2021)
Pattern recognition techniques are applied to various morphological descriptors to monitor the formation and propagation of surface defects of materials subjected to thermal shock. A low-cement high-alumina castable was ...
Effects of waste sulfur content on properties of self-compacting concrete
(Consejo Superior Investigaciones Cientificas-Csic, Madrid, 2020)
Self-compacting concrete (SCC) contains fine mineral fillers such as limestone powder. The idea of this study was to partially replace limestone with waste sulfur since it is hydrophobic, insoluble in water and therefore ...
Application of image analysis for cavitation erosion resistance monitoring of some engineering materials
(Bor : University of Belgrade, Technical Faculty, 2023)
Engineering materials are often used in various operating conditions including high temperatures,
pressure, aggressive solutions, or cavitation erosion. The phenomenon of cavitation erosion is expected
when fluid flow ...
Utilization of agro-industrial waste for removal of copper ions from aqueous solutions and mining-wastewater
(Elsevier Science Inc, New York, 2019)
In this study, unmodified lemon peel, as agro-industrial waste, was used to investigate removal efficiency of copper ions from aqueous solutions and mining wastewater. The effects of solution pH, adsorption time, metal ion ...
Removal of Fe2+, Zn2+ and Mn2+ from the mining wastewater by lemon peel waste
(Srpsko hemijsko društvo, Beograd, 2020)
This study is aimed to evaluate the possibility of lemon peel, as an agro-industrial waste, to remove Fe2+, Zn2+ and Mn2+ from single aqueous solutions and mining wastewater. For this purpose, the influence of various ...
Advanced damage resistance monitoring procedure on the composite materials? surface-exposed to cavitation testing
(Wear, 2021)
Morphology and development of surface damage of alumina-based materials, resulting from cavitation erosion is studied in this paper. Two series of samples were prepared: samples without fibers and those with the addition ...
Enhancing properties of concrete by addition of fly ash from a thermal power plant for application in geothermal systems / Poboljšanje svojstava betona dodatkom letećeg pepela iz termoelektrane za primenu u geotermalnim sistemima
(Beograd : Savez mašinskih i elektrotehničkih inženjera i tehničara Srbije - SMEITS, 2020)
Electric power in Serbia is predominantly provided by thermal power plants. All of eleven existing thermal power plants in Serbia use coal, mainly lignite in the electricity production process thus generating about 6 million ...
The influence of the shape and size of the AL2O3 particles on the flexural properties of the PMMA composite modified by the addition of dimethyl itaconate / Uticaj oblika i veličine čestica AL2O3 na savojna svojstva PMMA kompozita modifikovanog dodatkom dimetil itakonata
(Savez inženjera i tehničara Srbije, Beograd, 2018)
Dental materials have specific requirements regarding behavior in exploitation conditions. Poly (methyl methacrylate) (PMMA) is one of the most commonly used prosthetic materials. It is of interest to improve the mechanical ...
