Size and surface effects on the MRI relaxivity of manganese ferrite nanoparticle contrast agents
(Amer Chemical Soc, Washington, 2007)
Superparamagnetic MnFe2O4 nanocrystals of different sizes were synthesized in high-boiling ether solvent and transferred into water using three different approaches. First, we applied a ligand exchange in order to form a ...
The influence of thermomechanical treatment and chemical composition on recrystallization of Al-Mg alloys
(Savez inženjera metalurgije Srbije, Beograd, 2007)
Recrystallization behaviour of AlMg3, AlMg4.5Mn and AlMg6Mn alloy plates subjected to different thermomechanical treatments (TMTs), has been studied by means of optical microscopy and hardness measurements. Applied two-stage ...
New functionalities in cellulosic fibers developed by chemical modification / Celulozna vlakna novih funkcionalnih svojstava dobijanja hemijskim modifikovanjem
(Univerzitet u Nišu - Tehnološki fakultet, Leskovac, 2007)
This paper gives an overview of the current state in the field of cellulosic fibers functionalization by chemical modification. Emphasis is placed on the selective (periodate and TEMPO oxidation) and non-selective (permanganate ...
Synthesis and characterization of bioglass thin films
(Inst Materials Physics, Bucharest, 2007)
We report the successful pulsed laser deposition on medical grade Ti substrates of thin films made of two bioactive glasses in the SiO2 - Na2O- K2O - CaO - MgO - P2O5 system. The films were topographically and chemically ...
Supercritical carbon dioxide extraction of carrot fruit essential oil: Chemical composition and antimicrobial activity
(Elsevier Sci Ltd, Oxford, 2007)
Isolation of carrot fruit (Daucus carrota L., cultivar "Chanteney") essential oil by supercritical carbon dioxide was investigated from the pretreatment of herbaceous matrix and extraction conditions to the chemical ...
Electrophoretic deposition and thermal treatment of boehmite coatings on titanium / Elektroforetsko taloženje i sinterovanje prevlaka bemita na titanu
(Serbian Chemical Society, Belgrade, 2007)
An aqueous boehmite sol was prepared by the peptization of Al(OH)3. The electrophoretic deposition of boehmite coatings on titanium from the aqueous sol was performed at a constant voltage (from 1.0 to 10 V) and for a ...
A novel primal-mixed finite element approach for heat transfer in solids
(Springer, New York, 2007)
A new reliable primal-mixed finite element approach for the heat transfer analysis in solids, is examined in detail. The essential contribution is that both variables of interest, temperature and heat flux, are calculated ...
Photocatalytic degradation of textile dye C.I. reactive orange 16 in TiO2 water suspension by simulated solar light
(Association of the Chemical Engineers of Serbia, 2007)
The photodegradation of C.I. Reactive Orange 16 (RO16), commonly used as a textile dye, was investigated using TiO2 as a catalyst and the sun lamp. The experiments showed that TiO2 and simulated solar light are necessary ...
Crystallization shelf

The effect of substrate polarity on the lipase-catalyzed synthesis of aroma esters in solvent-free systems
(Elsevier, Amsterdam, 2007)
The aim of this study was to compare activities of commercial lipases in synthesis of various esters in solvent-free system and in isooctane. Moreover, the effect of substrate polarity (expressed as log P) on solvent-free ...
