Mechanical properties and microstructure of the ZrO25CaO/NiCrAl coating system / Mehaničke osobine i mikrostruktura sistema prevlaka ZrO25CaO/NiCrAl
(Engineering Society for Corrosion, Belgrade, Serbia, 2019)
ZrO25CaO is a versatile class of material that can be sintered or plasma spray deposited in combination with other materials on the implant substrate. Due to brittleness the organic ceramic hydroxyapatite Ca10(PO4)6(OH)2 ...
Distribution of saturated hydrocarbons in unweathered and erosional landforms
(Lodz University of Technology, 2019)
Badlands are worldwide erosional landforms. The
formation of different badland morphologies is due to
the type of sedimentary bedrock, especially texture
and cementation degree, as well as climate.
In this study badlandes ...

BIOSORBENTI ZA PREČIŠĆAVANJE OTPADNIH VODA IZ TEKSTILNE INDUSTRIJE / TEXTILE INDUSTRY WASTE WATERTREATMENT
(Beograd : Beogradska politehnika, 2019)
Jedna od najaktuelnijih tema u svetu je ekologija i zagađenje
životne sredine. Ispuštanje toksičnih materija iz raznih industrijskih
pogona u neposrednu okolinu dovodi do zagađenja vode, vazduha i zemljišta.
U pogonima ...
