Nonlinear frequency response analysis of nonisothermal adsorption controlled by macropore diffusion
(Pergamon-Elsevier Science Ltd, Oxford, 2014)
In this work, a nonlinear frequency response (NFR) approach is used for a theoretical study of nonisothermal adsorption controlled by macropore diffusion (NMD). Based on the nonlinear mathematical model on the particle ...
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 ...
Electrochemical determination of ascorbic acid using electrochemically deposited polyaniline
(Tatranské Matliare : Slovak Society of Chemical Engineering, 2014)
Electroconducting polymers are promising materials to be used in various fields including: batteries, capacitors, electronic devices, corrosion, biosensors and sensors[1,6]. Polyaniline is probably the most investigated ...
Behavior of sulfur-polymer matrix composites with different fillers under acid and salt influence
(Polymer-Matrix Composites: Types, Applications and Performance, 2014)
Based on the nature of the matrix material, modern composites can be generally classified into three categories: polymer matrix composites, metal matrix composites, and ceramic matrix composites. Polymer matrix composites ...
Electrospun Poly(vinylbutyral)/silica Composite Fibres for Impregnation of Aramid Fabrics
(Materiale Plastice, 2014)
The poly (vinyl butyral)/silica (PVB/SiO2) composite fibers were produced by the electrospinning process. The experiments were performed with the PVB solution in concentration of 10 wt.% where ethanol was used as the ...
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 ...
Synthesis of fluorine substituted hydroxyapatite nanopowders and application of the central composite design for determination of its antimicrobial effects
(Elsevier Science Bv, Amsterdam, 2014)
Synthetic biomaterials based on fluorine substituted hydroxyapatite are potentially attractive for orthopedic and dental implant applications. The new synthesis of fluorine substituted hydroxyapatite samples were done by ...
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. ...
Economizer water-wall damages initiated by feedwater impurities
(Savez hemijskih inženjera, Beograd, 2014)
The main causes of efficiency loss in thermal power plants are boiler tube failures that diminish unit reliability and availability, and raise the cost of the electric energy. For that reason, the regular examination of ...
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 ...
