Characterization of the sludge generated during the processing of iron ore in Omarska mine
(University of Belgrade, Faculty of Mining and Geology, Center for Environmental Engineering, 2017)
In present paper there were characterized sludge samples generated as an overflow during the processing of iron ore from Omarska mine (Bosnia and Herzegovina). With the aim to improve the utilization of minerals, we are ...
There are two twin shadows, but Einstein is one!
(Society of Thermal Engineers of Serbia, 2012)
2011 is the international year of chemistry, and it is exactly 100 years past after the P. Langevin promotion of “twin paradox” problem. The hundred year old problem still demands its solution. Twin paradox, established ...
The roughness of surface of aluminum after chemical and electrochemical treatment / Hrapavost površine aluminijuma nakon hemijske i elektrohemijske obrade
(Belgrade, Serbia : Serbian Society of Corrosion and Materials Protection UISKOZAM / Beograd, Srbija : Udruženje inženjera Srbije za koroziju i zaštitu materijala UISKOZAM, 2017)
In this paper chemical and electrochemical treatment of aluminium and measurement of roughness were carried out. Before chemical or electrochemical treatment of aluminium samples chemical preparation is done to remove oxide ...
Electrochemical characterization of La0.6Sr0.4CoO3 and La0.6Sr0.4CoO3 doped with RuO2 powders as the next generation supercapacitors
(Bor, Serbia : University of Belgrade, Technical Faculty in Bor, 2017)
In this study, La0.6Sr0.4CoO3 (LSC) powder and LSC doped with 20 wt.% RuO2 were investigated as anode materials for supercapacitor. Spherical submicron particles of La0.6Sr0.4CoO3 have been synthesized by ultrasonic spray ...
Novel method for synthesis of biocompatible hydroxyapatite/passive oxide layer on modified titanium surface
(Belgrade, Serbia : Serbian Society of Corrosion and Materials Protection UISKOZAM / Beograd, Srbija : Udruženje inženjera Srbije za koroziju i zaštitu materijala UISKOZAM, 2017)
Hydroxyapatite (HAp) is the most suitable biocompatible material for bone implant coatings. However, its brittleness is a major obstacle, and that is why, recently, research focused on creating composites. In this study, ...
