Electrospinning of the laser dye rhodamine B-doped poly(methyl methacrylate) nanofibers
(Srpsko hemijsko društvo, Beograd, 2014)
The electrospinning of rhodamine B (RhB)-doped poly(methyl methacrylate) (PMMA) is presented as a promising technique for processing photoluminescent nanofibers. Nanofibers with concentrations of RhB in PMMA between 0.05 ...
Corrosion properties of an aluminium alloy 7000 series after a new two step precipitation hardening / Otpornost prema koroziji aluminijumske legure serije 7000 posle novog dvostepenog termičkog taloženja
(Engineering Society for Corrosion, Belgrade, Serbia, 2014)
Corrosion properties of an aluminium alloy 7000 series were investigated by different electrochemical methods. The alloy was subjected to the one-step and to a new two-step precipitation hardening. Polarization measurements ...
The application of NIR spectroscopy with chemometric analysis for monitoring a powder blending process
(Srpsko hemijsko društvo, Beograd, 2014)
This paper reports the use of near infrared (NIR) spectroscopy as a process analytical technology (PAT) tool for monitoring the metformin (N,N-dimethylimidodicarbonimidic diamide) hydrochloride and poly(vinyl pyrrolidone) ...
Free-radical scavenging activity and antibacterial impact of Greek oregano isolates obtained by SFE
(Elsevier Sci Ltd, Oxford, 2014)
The antioxidant and antibacterial properties of Greek oregano extracts obtained by fractional supercritical fluid extraction (SFE) with carbon dioxide were investigated and compared with the properties of essential oil ...
A kinetics study of the methomyl electrochemical degradation in the chloride containing solutions
(Elsevier, Amsterdam, 2014)
The kinetics of the electrochemical degradation of methomyl has been study by the means of electrochemical techniques, UV-vis spectrophotometry, HPLC, and HPLC-ESI-MS in the sodium chloride containing solution. Degradation ...
Synthesis, characterization, and antimicrobial activity of poly(GMA-co-EGDMA) polymer decorated with silver nanoparticles
(Springer, New York, 2014)
Composite consisting of silver nanoparticles coordinated to poly(GMA-co-EGDMA) macroporous copolymer was prepared by attachment of amino group to the poly(GMA-co-EGDMA) in the reaction with ethylene diamine, and consequent ...
Surrounding gate long channel nanowire MOSFET modelling-extended analysis
(IOP Publishing Ltd, Bristol, 2014)
Based on the approximate solution of Poisson's equation in the case of a p-doped silicon body, an improved current-voltage characteristic model of long-channel cylindrical surrounding-gate Si nanowire MOSFET is proposed. ...
Finite element modelling of creep process - steady state stresses and strains
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2014)
Finite element modelling of steady state creep process has been described. Using an analogy of visco-plastic problem with a described procedure, the finite element method has been used to calculate steady state stresses ...
Copper nanoparticles with high antimicrobial activity
(Elsevier Science Bv, Amsterdam, 2014)
Copper (Cu) hydrosol containing small nanoparticles (NPs) (similar to 5 nm) with narrow size distribution were used to investigate antimicrobial activity toward representative microorganisms of public concern (Escherichia ...
