The particle size distribution of Ag powders obtained by chemical and electrochemical processes of synthesis
(Bor, Serbia : University of Belgrade, Technical Faculty in Bor, 2017)
The particle size distribution and the specific surface area (SSA) of silver powders obtained by chemical and electrochemical processes of synthesis have been analyzed . Silver particles produced by a chemical reaction ...
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, ...
Preliminary data on the crystal-chemical characteristics of beryl from Cer Mt. (Serbia)
(Scientific Annals, School of Geology, Aristotle University of Thessaloniki, 2010)
A beryl crystal from Cer Mt. (Serbia) studied in this paper was characterized by means of
XRPD and wet-chemical analyses. It has following unit cell dimensions: a = 9.2166(8) Å, c = 9.192(1) Å, V = 676.2(1) Å3 and ratio ...
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 ...
