Characterization and usefulness of corn cob as biosorbent for Pb2+, Cu2+ and Zn2+ ions removal from aqueous solutions / Karakterizacija i primena oklaska kukuruza za biosorpciju Pb2+, Cu2+ i Zn2+ jona iz vodenog rastvora
(Engineering Society for Corrosion, Belgrade, Serbia, 2016)
The objective of this study was to investigate corncob as biosorbent for heavy metals removal from aqueous solutions. All biosorption experiments were performed in batch system. The biosorbent were caracterized by thermal ...
Influence of microwave irradiation on hypochlorite decolorisation of synthetic dyes / Uticaj mikrotalasnog zračenja na obezbojavanje sintetskih boja hipohloritom
(Engineering Society for Corrosion, Belgrade, Serbia, 2016)
In this study three synthetic dyes were treated using hypochlorite or combination of hypochlorite and microwave irradiation in order to investigate factors which determine decolorisation of the investigated compounds. An ...

Dynamic mechanical properties of aramid fabrics impregnated with multiwalled carbon nanotubes / Dinamičko mehanička svojstva aramidnih lamina impregnisanih sa višeslojnim ugljeničnim nanocevima
(Engineering Society for Corrosion, Belgrade, Serbia, 2013)
Carbon nanotubes (CNT) represent allotropes of carbon with a cylindrical nanostructure. In multiwalled carbon nanotubes (MWCNT), graphitic layers make up concentric tubes. The multiwalled nanotubes length in our research ...
Application of exergy analysis in recycling streams / Primena eksergijske analize u reciklažnim tokovima
(Engineering Society for Corrosion, Belgrade, Serbia, 2015)
Materials for recycling always contain a certain degree of contamination. The presence of impurities i.e. contamination in the recycling streams causes a change in the composition of the original materials to recycle. As ...
Application of polyaniline in corrosion protection of metals / Primena polianilina u zaštiti metala od korozije
(Inženjersko društvo za koroziju, Beograd, 2012)
Polyaniline is probably the most investigated electroconducting polymer. This popularity is a result of its important features: existence of various oxidation states, electrical and optical activity, low cost monomer, ...
