The state of nickel in the silver modified NiMg/SiO2 vegetable oil hydrogenation catalysts
(Maik Nauka/Interperiodica/Springer, New York, 2009)
Two series of silver modified Ni-Mg materials were synthesized by precipitation-deposition on SiO2 support derived from two silica sources: diatomite activated at 800°C (Series a; Mg/Ni = 0.1 and SiO 2/Ni = 1.07) and ...
Investigation of the interface states in the SiO2– Si system by photoacoustic method
(EDP Sciences, 2005)
The interface states in SiO2 - Si system was investigated by photoacoustic (PA) spectroscopy. The amplitude and phase spectra were measured and analyzed in dependence on the wavelength of excitation optical beam. In the ...
Covalent modification of hexokinase by biologically active quinones
(Oxford : Blackwell Publishing, 2005)
In this work, inhibition of sulfhydryl containing glycolytic enzyme hexokinase by avarone and its derivatives was studied. The enzyme contains lysine and sulfhydryl residues, which can be modified by the quinone moiety. ...
Preparation of silver(I) complexes with itaconic acid-based hydrogels for biomedical application
(Materials and Manufacturing Processes, 2009)
Silver(I) complexes based on itaconic acid hydrogel were prepared and characterized in order to examine the potential use of these materials. FTIR, AFM, in vitro fluid-uptake, metal sorption, and antibacterial activity ...
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.
New Modified Microstrip Bandstop Filter with Only One (First Order) Bandstop
(9th International Conference on Telecommunications in Modern Satellite, Cable, and Broadcasting Serv, 2009)
In this paper, a new structure with only one (first order) bandstop is reported. A simple trapezoid shape of the microstrip line is introduced instead of the more complicated pattern. It obtains simple simulation, optimization ...
Adsorption-Desorption Noise in Plasmonic Chemical/Biological Sensors in Multiple Analyte Environment
(Smart Sensors, Actuators, and Mems Iv, 2009)
We analyzed the intrinsic noise of plasmonic sensors caused by the adsorption-desorption of gaseous analytes on the sensor surface. We analyzed a general situation when there is a larger number of different species in the ...
Vacuum MEMS sensor based on thermopiles - Simple model and experimental results
(Institute of Electrical and Electronics Engineers Inc., 2008)
This paper presents a simple model of MEMS thermopile based vacuum detector and experimental results obtained for sensors designed and fabricated at IHTM-IMTM. Sensors contain two thermopiles, each with 30 multilayer ...
Photoacoustic elastic bending method: Investigation of the surface recombination states
(26th International Conference on Microelectronics, Proceedings, MIEL 2008, 2008)
The recombination processes of surface modified Si samples by the PA elastic bending method were investigated. The experimental PA elastic bending signals were measured by using special constructed PA cell (the gas-microphone ...
A consideration of transparent metal structures for subwavelength diffraction management
(Institute of Electrical and Electronics Engineers Inc., 2006)
We considered theoretically and experimentally one-dimensional multilayered metallodielectric nanofilms with nanometric thickness for imaging below the diffraction limit. We investigated their behavior in the ultravioled ...
