Non-contact measurement of thickness uniformity of chemically etched Si membranes by fiber-optic low-coherence interferometry
(Institute of Electrical and Electronics Engineers Inc., 2008)
In this paper we present a contactless technique for thickness measurement of chemically etched Si membranes. This technique is based on low-coherence interferometry performed by single-mode fiber-optic sensing configuration. ...
Fabrication and characterization of AFM golden microcantilevers and measurement of small electromagnetic forces
(Institute of Electrical and Electronics Engineers Inc., 2008)
This paper presents results of research oriented towards developing a method for measurement of small electromagnetic forces using atomic force microscope (AFM). The method is based on the measurement of cantilever deflection ...
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 ...
Investigation of SiO/sub 2/ film on Si substrate by photoacoustic method
(Institute of Electrical and Electronics Engineers (IEEE)IEEE, 2004)
The effect of SiO/sub 2/ film on Si substrata (SiO/sub 2//Si) was investigated by photoacoustic spectroscopy. The amplitude and phase spectra were measured and analyzed in dependence on the wavelength of excitation optical ...
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. ...
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 ...
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 ...
Energy spectra and dynamics of surface states on silicon investigated by the photoacoustic method
(AIP Publishing, 2003)
The spectral and dynamic characteristics of surface energy states (SES) on a Si wafer are investigated by photoacoustic (PA) spectroscopy. The PA spectra were measured as a function of the wavelength and modulation frequency ...
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 ...
