Surface plasmon - Polariton assisted metal-dielectric multilayers as passband filters for ultraviolet range
(Polish Academy of Sciences, 2007)
We designed and fabricated metal-dielectric multilayers intended for passband filters in the ultraviolet range. We determined the dispersion characteristics by the Bloch approach to evanescent wave resonant coupling and ...
Morphology and capacitive properties of [RuOxH y/low-surface area carbon black] composite materials prepared by sol-gel procedure
(Materials Science Forum, 2005)
The morphology and the capacitive properties of carbon supported hydrous ruthenium oxide (RuOxHy/C), prepared by impregnation of low-surface area carbon black Vulcan® XC-72 R with solid phase of RuO xHy sol, were investigated ...
Structure and magnetic properties of nanocrystalline NiFe2O 4 prepared via precipitation route
(Polish Academy of Sciences, 2014)
Nanocrystalline Ni-ferrite was synthesized by modified precipitation method in which soluble starch is used as dispersing agent and Na2CO 3 as a precipitating agent. NiSO4-6H2O and Fe(NO3)3-9H2O were used as precursors for ...
NdFeB permanent magnets with various Nd content
(Polish Academy of Sciences, 2008)
Three kinds of commercial Nd-Fe-B based materials were compared using 57Fe Mössbauer spectroscopy and X-ray analysis: near the Nd 2Fe14B stoichiometry and with both lowered and raised Nd content. Magnetically hard Nd2Fe14B ...
Phase composition and magnetic properties of multiphase melt-spun Nd 4.3Fe76.2B19.5alloy
(Materials Science Forum, 2007)
Phase transformations and magnetic properties of multiphase Nd 4.5Fe76.2B19.5 alloy were investigated in the temperature range of heat treatment 600-700°C. The influence of different heat treatment regimes was observed by ...
Mass transfer and fluid flow visualization in packed and fluidized beds by the adsorption method
(Maik Nauka/Interperiodica/Springer, New York, 2009)
Mass transfer coefficient (j D ) between fluid and column wall in liquid packed and fluidized beds of spherical inert particle has been studied experimentally using adsorption method. Experiments were conducted in column ...
Segmented thermistors printed by NTC nanometric paste and applied in volume air-flow sensors
(Materials Science Forum, 2006)
An investigation path starting from (Mn,Ni,Co,Fe)3O4 nanometric powder preparation, NTC thick-film characterization, realization and optimization of new planar thermistor geometries to custom design thermistors and their ...
Electrochemical behavior of 5-substituted 2-alkylidene-4-oxothiazolidine derivatives studied by cyclic voltammetry
(Maik Nauka/Interperiodica/Springer, New York, 2007)
This study demonstrates the electrochemical activity of selected 2-alkylidene-4-oxothiazolidine compounds containing different substituents at the C5-position on the Pt-electrode in 0.1 M TBAHFP + MeCN in the potential ...
Investigation of the effects of Ar plasma etching in Si surface by photoacoustic method
(EDP Sciences, 2005)
The effects of Ar plasma treatment on the Si surface were investigated by photoacoustic spectroscopy and atomic force microscopy. We studied the surface structure as a function of plasma experimental parameters to correlate ...
Nanoscale topography of GC/Pt-C and GC/Pt-Ru-C electrodes studied by means of STM, AFM and XRD methods
(Materials Science Forum, 2006)
Electrodes, assigned as GC/Pt-C and GC/Pt-Ru-C, were formed by deposition of Pt-based catalysts (47.5 wt % Pt + high surface area carbon) and (54 wt. % Pt-Ru alloy + high surface area carbon) on glassy carbon (GC) discs. ...
