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 ...
Magnetic field influence on silicon surface periodic structures obtained by plasma flow action
(25th International Conference on Microelectronics, MIEL 2006 - Proceedings, 2006)
External magnetic field influence on silicon submicron surface periodic structures obtained by the action of nitrogen supersonic quasistationary compression plasma flow (CPF) is studied. CPF is generated by magnetoplasma ...
Influence of thermal treatment on polyphenolic compounds and antioxidant properties of Quercus robur kernels / Uticaj termičkog tretmana na polifenolne sastojke i antioksidantna svojstva semena lužnjaka, Quercus robur
(Pharmaceutical Association of Serbia, Belgrade, Serbia, 2006)
Polyphenolic compounds and antioxidant properties of dried MeOH extracts of native (QN) and thermally treated (QT) kernels of English Oak, Quercus robur were investigated. The content of total and simple polyphenols and ...
Scanning probe-shaped nanohole arrays with extraordinary optical transmission as platform for enhanced surface plasmon-based biosensing
(Institute of Electrical and Electronics Engineers Inc., 2006)
We analyzed the use of subwaveleneth ordered nanohole patterns for detection of miniscule amounts of biological analytes. Owing to their surface plasmon resonance (SPR) operation, such structures show an extraordinarily, ...
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 ...
Optimization of micro/nanooscillator parameters for analysis of transient adsorption processes
(Institute of Electrical and Electronics Engineers Inc., 2008)
We consider optimization of parameters of micro/nanooscillators intended for investigation of adsorptiondesorption (AD) processes, which are fast in comparison with the response rate of the oscillator itself. We consider ...
Surface Texture Parameters in Optimizing Magnetic Force Images
(Belgrade : Astronomical Observatory, 2008)
In this work, the optimizing conditions necessary for magnetic field gradient imaging using Atomic Force Microscopy (AFM) and Magnetic Force Microscopy (MFM) in a lift mode have been established. 55 nm thick Co thin film ...
