The influence of modification methods on physico-chemical and sorption properties of sepiolite Umnoženo za odbranu. / Proučavanje uticaja različitih postupaka modifikacije na fizičko-hemijske karakteristike i sorpciona svojstva sepiolita
(Univerzitet u Beogradu, Tehnološko-metalurški fakultet, 2012)
The aim of this study was to investigate the influence of modification of natural sepiolite using: 3-mercaptopropyltrimethoxysilane (HS(CH2)3Si(OCH3)3), [3-(2- aminoethylamino)propyl]trimethoxysilane ((CH3O)3Si(CH2)3NH(CH2)2NH2)), ...
High strength thermoresponsive semi-IPN hydrogels reinforced with nanoclays
(Wiley Periodicals, Inc., 2012)
Two series of nanoclay reinforced, thermoresponsive hydrogels were prepared, one based on poly(N-isopropylacrylamide) (PNIPA) and the other on semi-interpenetrating networks containing PNIPA and poly(N-vinyl pyrrolidone) ...
Removal of toxic metals from industrial sludge by fixing in brick structure
(Elsevier Sci Ltd, Oxford, 2012)
The aim of this study was to test utilization possibilities of industrial sludge in masonry industry, as well as risk of toxic elements leaching potential. Sludge is generated in a hot-dip galvanizing process after waste ...
Delimično topljenje i centrifugiranje kao nova metoda pred-tretmana metaličnog granulata e-otpada: Preliminarni laboratorijski test
(Bor : Tehnički fakultet, 2012)
Ogromne količine otpada od električnih i elektronskih proizvoda (e-otpad) koje se u svetu
svakodnevno generišu ne prerađuju se na adekvatan način. Rast cena metala koji se beleži
poslednjih godina, glavni je razlog što ...
Industrial use of a new ultrasound spray for coolin and wet gas treatment in the pyrometallurgical processes
(141st Annual Meeting and Exhibition, TMS 2012, 2012)
This paper presents the results of a new industrial use the ultrasonic spray for gas cooling from sulphide copper concentrate roasting in the fluo solid reactor and the results of wet gas treatment (washing) in the scrubber ...
Assessment of the behaviour of fatigue loaded HSLA steel welded joint by applying fracture mechanics parameters / Procena ponašanja zavarenog spoja HSLA čelika opterećenog na zamor primenom parametara mehanike loma
(Society for Structural Integrity and Life, Institute for Material Testing, 2012)
From a fracture mechanics point of view on welded joints, it is assumed that the welded joint is pre-cracked such as that the fatigue life of the pre-cracked structure is then determined by the period of crack growth under ...
Review: The approaches for estimation of limit of detection for ICP-MS trace analysis of arsenic
(Talanta, 2012)
The analytical properties of an analytical method must be evaluated through validation protocols. Beside specificity and/or selectivity, linearity of calibration, repeatability and accuracy, the most important parameters ...
In vitro control of multiplication of some food-associated bacteria by thyme, rosemary and sage isolates
(Elsevier Sci Ltd, Oxford, 2012)
Antibacterial activity of thyme, rosemary and sage isolates obtained by supercritical fluid extraction and hydrodistillation was investigated on Geobacillus stearotermophillus, Bacillus cereus, Bacillus subtilis var. niger, ...
In vivo MRI biocompatibility evaluation of functionalized carbon fibers in reaction with soft tissues / In vivo MRI procena biokompatibilnosti funkcionalizovanih karbonskih vlakana u reakciji sa mekim tkivom
(Univerzitet u Beogradu - Fakultet veterinarske medicine, Beograd, 2012)
In modern medicine implants are very important and so is their design and choice of materials. Almost equally important is the choice of imaging technique used to in vivo monitor their fate and biocompatibility. The aim ...
Structure and luminescence properties of Eu3+ doped TiO2 nanocrystals and prolate nanospheroids synthesized by the hydrothermal processing
(Elsevier Sci Ltd, Oxford, 2012)
We report on a new approach to the synthesis of Eu3+ doped TiO2 nanocrystals and prolate nanospheroids. They were synthesized by shape transformation of hydrothermally treated titania nanotubes at different pH and in the ...
