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 ...
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 ...
Premazi na bazi cirkona sa primenom u Lost Foam procesu livenja / Zircon-based coating for the applications in Lost Foam casting process
(Savez hemijskih inženjera, Beograd, 2012)
U ovom radu je istraživana mogućnost dobijanja novih vatrostalnih premaza na bazi cirkona koji bi imali primenu u livarstvu. Optimizacija sastava premaza kontrolisana reološkim svojstvima postignuta je primenom različitih ...
Modeling of release kinetics of silver nanoparticles from novel alginate nanocomposites aimed for biomedical applications
(Wiley-Blackwell, Hoboken, 2012)
Quantification of viable spray-dried potential probiotic lactobacilli using real-time PCR
(Srpsko biološko društvo, Beograd, i dr., 2012)
The basic requirement for probiotic bacteria to be able to perform expected positive effects is to be alive. Therefore, appropriate quantification methods are crucial. Bacterial quantification based on nucleic acid detection ...
The phase equilibrium of triglycerides and ethanol at high pressure and temperature: The influence on kinetics of ethanolysis
(Elsevier Science Bv, Amsterdam, 2012)
Biodiesel synthesis by ethanolysis of triglycerides conducted under high pressure and at elevated temperature can lead to high levels of conversion and biodiesel yield over short reaction time. The vapour-liquid or ...
Precipitation of the beta-phase and corrosion behavior of an al-6.8 wt.% mg alloy
(John Wiley & Sons, Chichester, 2012)
This study was performed on the Al-Mg alloy with the chemical composition: Al-Mg6.8-Mn0.51-Fe0.2-Si0.1. As-received cold rolled material (O-temper) was subjected to (i) cold rolling and annealing at 265 degrees C and 320 ...
