Influence of monomer and crosslinker molar ratio on the swelling behaviour of thermosensitive hydrogels / Uticaj molarnog odnosa monomera i umreživača na karakteristike bubrenja termoosetljivih hidrogelova
(Association of the Chemical Engineers of Serbia, 2012)
The synthesis of the poly(N-isopropylacrylamide-co-2-hydroxypropyl-methacrylate) hydrogel along with the analysis of the residual monomers content and influence of monomer and crosslinker molar ratios on the swelling ...
Recovery of the damages of a welded steel structure of a coal-reloading bridge: Methodological approach
(Univerzitet u Novom Sadu - Fakultet tehničkih nauka, Novi Sad, 2012)
In present paper, the methodological approach to the analysis of the causes of failures and to recovery of the damages has been presented using, as an example, the fracture and damage of a welded steel structure of a ...
Microstructure evolution of a modified AA5083 aluminum alloy during a multistage homogenization treatment
(Elsevier Science Inc, New York, 2012)
The microstructure evolution of the industrially cast AA5083 modified aluminum alloy during the multistage homogenization treatment was investigated by means of optical, SEM and TEM imaging and microanalysis techniques. ...
Mechanism and dynamics of shrinking island grains in mazed bicrystal thin films of Au
(Pergamon-Elsevier Science Ltd, Oxford, 2012)
This work investigates the mechanism and dynamics of grain boundary migration driven by capillary forces via in situ electron microscopy, complemented by molecular-dynamics simulations. Using thin films of Au with the mazed ...
Encapsulation and release profiles of caffeine from microparticles
(6th Central European Congress on Food, CEFood 2012, 2012)
The purpose of this study was to encapsulate caffeine in alginate-chitosan cross-linked microparticles enriched with ascorbic acid by applying electrostatic extrusion technique. Three different forms of caffeine were ...
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 ...
Synthesis and properties of methacrylic acid based hydrogels modified with zeolites / Sinteza i svojstva hidrogelova na bazi metakrilne kiseline modifikovanih zeolitima
(Univerzitet u Beogradu, Tehnološko-metalurški fakultet, 2012)
In the first part of this work hydrogels based on partially and completely neutralized methacrylic acid were synthesized by free-radical polymerization and crosslinking at 80 °C, conventionally and in microwave field. By ...
Structural and optical characterization of hemimorphite with flower-like morphology synthesized by a novel low-temperature method
(Materials Letters, 2012)
We report on novel, low temperature synthesis of well crystallized hemimorphite zinc silicate Zn4Si2O7(OH)(2)(H2O) (ZSO) with flower-like morphology, via one-pot method that includes the assistance of a non-ionic block ...
Effects of additives on nickel (ii)-chloride hydrogen reduction for production of nanocomposite catalysts
(Editura Stiintifica Fmr, Bucharest, 2012)
Catalysts based on nickel, as active component, exhibit suitable properties in various heterogeneous catalysis processes; however, they quickly deactivate due to deposits formation during exploitation and sintering at ...
