The thermal stability of the external invertase isoforms from Saccharomyces cerevisiae correlates with the surface charge density
(Elsevier France-Editions Scientifiques Medicales Elsevier, Paris, 2012)
Understanding the effect of surface charge on the stability of proteins is one prerequisite for "tailoring" proteins with increased thermal stability. Here, we investigated the origin of the altered thermal stability ...
Fluctuations of the mass adsorbed on microcantilever sensor surface in liquid-phase chemical and biochemical detection
(Elsevier, 2012)
We present a simple mathematical model of adsorbed mass fluctuations in microcantilever sensors operating in liquids, taking into account the effects of the transfer process of analyte molecules from a solution to the ...
Characterisation of New Bacillus circulans Strain Isolated from Oil Shale
(Croatia : University of Zagreb, Faculty of Food Technology and Biotechnology, 2012)
A new strain of Bacillus sp. was obtained during experiments of oil shale demineralization, which were carried out in order to get 'pure' organic matter (kerogen). The demineralization efficiency of newly isolated strain ...
The kinetics of the hydrogen oxidation reaction on WC/Pt catalyst with low content of Pt nano-particles
(Elsevier, 2012)
The catalytic activity of WC/Pt electrocatalysts towards hydrogen oxidation reaction (HOR) in acid solution was studied. Tungsten carbide (WC) prepared by polycondensation of resorcinol and formaldehyde in the presence of ...
Electrochemically deposited nano fibrous polyanilne for amperometric determination of glucose
(Inst Materials Physics, Bucharest, 2012)
Electrochemical deposition of polyaniline (PANI) on graphite electrode was performed galvanostaticaly at constant current density in the range of 1.0 - 5.0 mA cm(-2) from aqueous acidic electrolyte containing aniline ...
Synthesis and structure of a Ni(II) complex with N ',N '(2)-bis[(1E)-1-(2-quinolyl)methylene]propanedihydrazide: multiple intramolecular CH center dot center dot center dot pi interactions between quinoline and quinolineimine chelate
(Taylor & Francis Ltd, Abingdon, 2012)
A new malonic dihydrazide-based ligand, N',N'(2)-bis[(1E)-1-(2-quinolyl)methylene]propanedihydrazide (H(2)L3), has been prepared and characterized by elemental analysis, IR, C-13 NMR, and H-1 NMR spectroscopies. In the ...
Morphology and internal structure of copper deposits electrodeposited by the pulsating current regime in the hydrogen co-deposition range
(Springer, New York, 2012)
The effect of the regime of pulsating current (PC) on copper electrodeposition in the hydrogen co-deposition range was examined by the techniques of scanning electron and optical microscopes. The quantities of evolved ...
Synthesis, structure and solvatochromic properties of some novel 5-arylazo-6-hydroxy-4-phenyl-3-cyano-2-pyridone dyes
(BMC, 2012)
Background: A series of some novel arylazo pyridone dyes was synthesized from the corresponding diazonium salt and 6-hydroxy-4-phenyl-3-cyano-2-pyridone using a classical reaction for the synthesis of the azo compounds. ...
Nanotechnological Enhancement of Infrared Detectors by Plasmon Resonance in Transparent Conductive Oxide Nanoparticles
(Assoc Mechanical Engineers Technicians Slovenia, Ljubljana, 2012)
We investigated the use of plasmonic nanotechnology to enhance the performance of semiconductor infrared detectors. An increase of quantum efficiency, responsivity and specific detectivity is obtained by applying transparent ...
Interactions of N-{[2-(4-phenyl-piperazin-1-yl)-ethyl]-phenyl}-2-aryl-2-yl-acetamides and 1-{[2-(4-phenyl-piperazin-1-yl)-ethyl]-phenyl}-3-aryl-2-yl-ureas with dopamine D-2 and 5-hydroxytryptamine 5HT(1A) receptors
(Oxford : Pergamon-Elsevier Science Ltd, 2012)
It is suggested that the ratio of dopamine D-2 to 5-hydroxytryptamine 5-HT1A activity is an important parameter that determines the efficiency of antipsychotic drugs. Here we present the synthesis of N-{[2-(4-phenyl-pipe ...
