Heavy metals in soils of Srem (Vojvodina)
(Bor : University of Belgrade-Technical Faculty in Bor, 2017)
Potentially harmful trace elements pollution in soils is a worldwide environmental problem that has received increasing attention over the last few decades because of its adverse effects. Metals in soils are present in ...
Koncentracija i biodostupnost toksičnih metala u zemljištu Srednjeg Banata (Vojvodina, Srbija)
(Visoka škola strukovnih studija, Beogradska Politehnika, 2017)
Stepen kontaminacije zemljišta toksičnim elementima definiše se u skladu sa važećim pravilnicima na teritoriji R. Srbije. Neki od definisanih elemenata su uvek toksični za biljke ili ljude (Pb, Cd, As, Hg, V, Sb, Be), a ...
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, ...
