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. ...
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 ...
Diagnostic spectroscopic and computer-aided evaluation of malignancy from UV/VIS spectra of clear pleural effusions
(Elsevier, Amsterdam, 2014)
The automated, computer-aided method for differentiation and classification of malignant (M) from benign (B) cases, by analyzing the UV/VIS spectra of pleural effusions is described. It was shown that by two independent ...
Microwave as a pre-treatment of triticale for bioethanol fermentation and utilization of the stillage for lactic acid fermentation
(Elsevier, Amsterdam, 2014)
The aims of this research were to investigate the potential for improvement of bioethanol fermentation by microwave pre-treatment of triticale, as well as the possibility of using triticale stillage (a by-product of ...
Cardiovascular Drugs in Environmental Waters and Wastewaters: Method Optimization and Real Sample Analysis
(Aoac Int, Gaithersburg, 2014)
A sensitive method for determination of the eight most prescribed drugs used in combined cardiovascular therapy in Serbia was developed and optimized. The method was based on SPE followed by LC/ion trap-MS/MS with positive ...
Prediction and correlation of viscosity of binary mixtures of ionic liquids with organic solvents
(Elsevier, Amsterdam, 2014)
Viscosities of ten binary liquid mixtures consisting of ionic liquids and organic compounds, determined at atmospheric pressure and in a wide temperature range, were calculated using two different approaches, predictive ...
Challenging analytical task: analysis and monitoring of arsenic species in water
(Gheorghe Asachi Technical University of Iasi, Romania, 2014)
Analysis and monitoring of arsenic is still a challenging analytical task. Due to its complex behaviour (different forms of arsenic that can be present depending on pH and oxidation states of arsenic) as well as demanding ...
Recycling of silver-plated brass for production of high purity copper and ultrafine silver powder for electric contacts
(Bulgarian Chemical Communications, 2014)
The paper presents an improved process for recycling of silver-plate brass housing. Silver and copper are recovered with a purity of 99.99 % and 99.90 %, respectively, with the aim of obtaining materials of higher value ...
Sol-gel synthesis and characterization of iron doped mullite
(Elsevier Science Sa, Lausanne, 2014)
Amorphous powders of iron doped 3:2 mullite (3Al(2)O(3)center dot 2SiO(2)) were prepared by sol-gel combustion process using ethanol-water solutions of Al(III) nitrate, Fe(III) nitrate, TEOS and urea. Compositions up to ...
