Quantification of the lift height for magnetic force microscopy using 3D surface parameters
(Elsevier, 2010)
In this work, the quantitative conditions for the lift height for imaging of the magnetic field using magnetic force microscopy (MFM) were optimized. A thin cobalt film deposited on a monocrystalline silicon (1 0 0) substrate ...
Fundamental aspects of copper electrodeposition in the hydrogen Co-deposition range
(Belgrade, Serbia : Engineering Society for Corrosion, 2010)
This a review paper considering fundamental aspects of copper electrodeposition at high overpotentials where parallel to copper electrodeposition, hydrogen evolution reaction occurs. The two types of copper deposits are ...
Immobilization of Cell Wall Invertase Modified with Glutaraldehyde for Continuous Production of Invert Sugar
(American Chemical Society (ACS), 2010)
Yeast cell wall invertase (CWI) was modified with dimethyl suberimidate, glutaraldehyde, formaldehyde, and sodium periodate. Retained activity after modification was 45% for CWI modified with formaldehyde, 77% for CWI ...
Field effect transistor based on protons as charge carriers
(Elsevier, 2010)
We demonstrated a field effect transistor based on the modulation of the proton flow in confined water-containing nanochannels. The device resembles an MOSFET transistor with the difference that the charge carriers here ...
New products in response to technological changes in the market / Novi proizvodi kao odgovor tehnološkim promenama na tržištu
(Tehnika - Kvalitet, standardizacija i metrologija, 2010)
The paper presents and analyzes a new product CMTM's. Selection and evaluation of new products that will succeed in the market depends on the product development process and management companies. Development, testing and ...
STACKING INTERACTIONS BETWEEN PYRIDINE FRAGMENTS IN CRYSTAL STRUCTURES OF TERPYRIDYL COMPLEXES
(Univ Babes-Bolyai, Cluj-Napoca, 2010)
In the crystal structures of terpyridyl complexes from the Cambridge Structural Database (CSD) stacking interaction between the pyridine fragments were studied. Square-planar complexes where the distance between the centers ...
Fluctuations of the adsorbed mass and the resonant frequency of vibrating MEMS/NEMS structures due to multilayer adsorption
(Elsevier, 2010)
This paper presents the analysis of fluctuations of both the number and the mass of particles adsorbed on the surface of MEMS/NEMS structures, as well as the fluctuations of the micro/nanostructure resonant frequency, in ...
Purification and properties of trypsin-like enzyme from the midgut of morimus funereus (coleoptera, cerambycidae) larvae
(Wiley-Blackwell, Hoboken, 2010)
Trypsin-like enzyme (TLE) from the anterior midgut of Morimus funereus larvae was purified by anion exchange chromatography and gel filtration chromatography and characterized. Specific TLE activity was increased 322-fold ...
Bromophilic substitution/carbophilic substitution cascade reactions of alpha,alpha-dibromo-2-methoxyacetophenone with C-, N- and O-nucleophiles
(Oxford : Pergamon-Elsevier Science Ltd, 2010)
alpha,alpha-Dibromo-2-methoxyacetophenone reacts, under mild reaction conditions, with C-, N- and O-nucleophiles via a bromophilic substitution/protonation/carbophilic substitution cascade process to afford alpha-monosub ...
A trapezoidal microstrip bandstop filter with efficient suppression of undesired stopbands
(National Institute of Optoelectronics, 2010)
A new bandstop filter implemented as a cascade of trapezoidally shaped cells is presented. The proposed bandstop filter suppresses many undesired stopbands at higher frequencies. The cell design is specified by two variables ...
