Vacuum Fluctuations in Optical Metamaterials Containing Nonlinear Dielectrics
(Polish Academy of Sciences, 2009)
We investigated the influence of zero-point fluctuations (vacuum fluctuations, optical quantum noise) to the optical response of electromagnetic metamaterials containing dielectrics with third-order Kerr-like nonlinearity. ...
Strukturne karakteristike galvanskih prevlaka bakra / Structural characteristics of electrodeposited copper coatings
(Bosnia and Herzegovina : University of East Sarajevo, Faculty of Technology, 2009)
Uzorci bakra su podvrgnuti mehaničkom i elektrohemijskom glačanju u odgovarajućim elektrolitima za elektrohemijsko glačanje. Na tako prethodno pripremljene površine supstrata izvršeno je taloţenje prevlaka bakra iz dva ...
Characterization of double oxide system Cu-Cr-O supported on gamma-Al2O3
(Maik Nauka/Interperiodica/Springer, New York, 2009)
Series of alumina supported chromium-copper catalysts were prepared by co-impregnation method. The samples were characterized by X-ray diffraction, X-ray photoelectron spectroscopy and UV-visible diffuse reflectance ...
AFM and SEM-EDS examination of highly dispersed heteropolyacids supported on MCM 41 and SBA 15 mesoporous materials
(Natl Inst Optoelectronics, Bucharest-Magurele, 2009)
Heteropolyacids (HPAS) H(3)PMo(12)O(40) (HPM) and H(4)PVMo(11)O(40) (HPVM) supported on mesoporous pure-silica and Al, Fe modified molecular sieve MCM-41 and SBA-15 have been prepared and characterized by atomic force ...
beta-Carotene removal from soybean oil with smectite clay using central composite design
(Maik Nauka/Interperiodica/Springer, New York, 2009)
In this study removal of beta-carotene from soybean oil by adsorption on acid activated smectite clay from Serbia was investigated and a factorial 2(3) experimental design was applied. The effects of relevant factors, such ...
Electrochemical Oxidation of Phenol on Metal-Impregnated Zeolite Electrodes
(Wiley-V C H Verlag Gmbh, Weinheim, 2009)
Nanodispersed metallic clusters of platinum, silver and cobalt were incorporated into NaX zeolite cavities by impregnation with acetone solution of corresponding acetylacetonates and solvent evaporation followed by ...
Analytical modelling of thermopile based flow sensor and verification with experimental results
(Elsevier, 2009)
A novel, simple approach for analytical modelling of thermal flow sensors has been implemented. It is based on unification of results obtained using the already developed two-zone analytical model and theory of laminar ...
Analyse of One Type of Resonant Cell
(9th International Conference on Telecommunications in Modern Satellite, Cable, and Broadcasting Serv, 2009)
Analyse of one type of resonant cell is proposed. One to three cells are combined into a low pass filter. The filter design curves for various substrates and cut off frequencies are presented.
Performance limits to the operation of nanoplasmonic chemical sensors: noise-equivalent refractive index and detectivity
(Spie-Soc Photo-Optical Instrumentation Engineers, Bellingham, 2009)
We considered figures of merit for chemical and biological sensors based on plasmonic structures and utilizing adsorption/desorption mechanism. The operation of these devices in general is limited by noise determining the ...
Structural and textural properties of Al,Fe-pillared clay catalysts
(Maik Nauka/Interperiodica/Springer, New York, 2009)
Metal oxide pillared interlayered clays (PILCs) represent a new class of materials that have found a wide range of potential applications including catalytic oxidative degradation of organic pollutants in water. Al,Fe-pillared ...
