Damage level evaluation of zircon samples caused by cavitation erosion using image analysis
(Bor : University of Belgrade - Technical Faculty in Bor, 2017)
This study is focused on monitoring the degradation level of zircon based ceramic materials during exposure to cavitation. In addition to conventional degradation monitoring methods, weight loss measuring, the emphasis is ...
Cavitation damage of mullite ceramic: implementation of image analysis
(Bor : University of Belgrade - Technical Faculty in BorBor : Mining and Metallurgy Institute Bor, 2016)
The paper presents the results of testing the mullite ceramics in terms of cavitation erosion. Mullite samples were sintered at 1200 °C. To determine the cavitation resistance the ultrasonic vibration method with stationary ...
Valorization of secondary sulfur from oil refining process for sulfur concrete production
(Bor : University of Belgrade - Technical Faculty in Bor, 2015)
Modification of conventional building materials is commonly realized using different waste materials. In this research, the use of secondary sulfur as binding agent in concrete was analyzed. Sulfur concrete is a thermoplastic ...
Environmental influence on service life expectancy of ceramic structures
(Политехпериодика/Politehperiodika, 2015)
During the service life, materials are exposed to environmental influences. The aim of this research is to analyze behavior of sulfur concrete compared to Portland cement concrete in acid environment. It has been shown ...
Leaching behavior of sulfur concrete with fly ash used for removal of heavy metals from wastewater
(Belgrade : Mining institute BelgradeAcademy of Engineering sciences of SerbiaUniversity of Belgrade, 2015)
When considering the materials that have become waste in a technological process, one way of their immobilization is for the production of certain new materials. The basic fact is to provide the environmentally acceptable ...

(Union of Mechanical and Electrical Engineers and Technicains of Serbia (SMEITS)Society for Renewable Electrical Power Sources, 2023)
Electric vehicles have become increasingly popular in recent years due to general global
warming but also due to technological advances, cost reductions, increased battery charging capabilities,
etc. In order to achieve ...
Chromium, Nickel, and Cobalt in soils of Srem and C. Banat
(Ecological Movement of Novi Sad, 2017)
This paper reports the concentration and sources of chromium, nickel and cobalt in soil samples from the Srem and Central Banat (Vojvodina, Serbia). Different methods were applied to identify the sources of elements and ...
Alkali modification of fly ash for adsorption of selected dyes
(Belgrade : The Academy of Applied Technical Studies "Belgrade", 2023)
Fly ash (FA) is an industrial waste material generated during coal combustion in thermalpower plants. In order to reuse this kind of industrial waste, and at the same time to reduce itsquantity, fly ash was used as a cheap ...
Predicting the modulus of elasticity of biocompatible titanium alloys using machine learning
(Belgrade : Association of Metallurgical Engineers of Serbia, 2023)
Titanium alloys are widely employed in various fields, particularly in biomedical engineering, due to their mechanical and corrosion resistance properties combined with good biocompatibility. The modulus of elasticity is ...
The importance of sociodemographic characteristics for the development of environmental literacy / Značaj sociodemografskih karakteristika za razvoj ekološke pismenosti
(Institute for Educational Research, 2023)
Environmental literacy is essential for addressing the environmental challenges of our time. By improving the environmental literacy of children and the youth, we can help create a more sustainable future for all. Nevertheless, ...
