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 ...
Applicability of risk-based maintenance strategy to a penstock / Strategija održavanja zasnovana na riziku - primenljivost na cevovod
(Society for Structural Integrity and Life, Institute for Material Testing, 2012)
The risk of brittle fracture of the penstock of the reversible pump turbine is recognized in an early stage of design. To reduce the cost of penstock construction one tunnel is accepted. The HSLA steel of 700 MPa yield ...
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 ...
Microstructural properties and cavitation behavior of hypereutectic Al-Si alloy obtained by rheocasting process / Mikrostrukturna svojstva i kavitaciono ponašanje nadeutektičke Al-Si legure dobijene reokasting postupkom
(Engineering Society for Corrosion, Belgrade, Serbia, 2014)
The purpose of this study was to investigate possible application of AlSi alloy produced by rheocasting process in cavitation conditions. A rheocasting process was used to refine the as cast microstructure and improve the ...
Modeling of disperse dye adsorption on modified polyester fibers
(University of Novi Sad, Faculty of Technology, 2020)
The results of the research on the ability of adsorption of dye on polyester fibers at a temperature of 98 °C are presented in this paper. The fibers were previously modified in aqueous solutions of NaOH, KOH or Al(OH)3. ...
CO tolerant Pt/Ru0.7Ti0.3O2 nanocatalyst for hydrogen oxidation reaction / Pt/Ru0,7Ti0,3O2 kao nanokatalizator za oksidaciju vodonika i njegova tolerancija na CO
(Engineering Society for Corrosion, Belgrade, Serbia, 2018)
The oxidation of pure H2 and H2/CO mixture (100 ppm CO) was investigated on Pt nanocatalyst supported on Ru0.7Ti0.3O2 (Pt /Ru0.7Ti0.3O2) by linear sweep voltammetry at a rotating disc electrode in 0.1 M HClO4. The results ...
Indentation behaviour of 'soft film on hard substrate' composite system type / Ponašanje kompozitnih sistema tipa 'mek film na tvrdom supstratu' na testu utiskivanja
(Engineering Society for Corrosion, Belgrade, Serbia, 2015)
This investigation has been carried out in order to analyse and compare the hardness response of different composite systems of the same type, named 'soft film on hard substrate' composite system. Composite systems of mono- ...
Oxidation and erosion behaviour of SiC-HfC multilayered composite
(Univerzitet u Novom Sadu - Tehnološki fakultet, Novi Sad, 2014)
The fabrication of SiC-HfC ceramic composite via self-propagating high-temperature synthesis and simultaneous consolidation was investigated. Dense composite consisting of alternating layers of SiC and HfC was obtained by ...
Photocatalytic degradation of carbamate insecticides: Effect of different parameters / Fotokatalitička degradacija karbamatnih insekticida - efekti različitih parametara
(Institute of Pesticides and Environmental Protection, 2019)
Photocatalytic degradation of a model compound of the carbamate insecticide carbofuran in water was studied using polychromatic light and ZnO and TiO2 catalysts. The influence of operational parameters, such as reaction ...
