Kinetic parameters for thermal inactivation of soluble peroxidase from needles of Serbian spruce Picea omorika (Pancic) Purkyne
(General Physiol And Biophysics, Bratislava, 2009)
Thermal inactivation of peroxidase (POD) in an extract of Picea omorika (Pancic) Purkyne needles initiated by heat treatment was studied. This is the first study of this kind on a conifer species. Non-linear regression ...
Characterization of electrodeposited Cd-Co alloy coatings by anodic linear sweep voltammetry
(Pergamon-Elsevier Science Ltd, Oxford, 2009)
The electrodeposited Cd-Co alloys were characterized by the anodic linear sweep voltammetry (ALSV) technique in the solution of 1 M NaCl (pH 2). It is shown that Cd-Co alloys could be deposited with high current efficiency ...
Micro-flow sensor for water using NTC thick film segmented thermistors
(Emerald Group Publishing Ltd, Bingley, 2009)
Purpose - The purpose of this paper is to apply negative thermal coefficient (NTC) thick film segmented thermistors (TFSTs) in a micro-flow sensor for water. Design/methodology/approach - A TFST is printed using NTC paste ...
Structural analysis of Zn2TiO4 doped with mgo
(Springer New York LLC, 2009)
The starting mixtures of ZnO, TiO2, and MgO (0, 1.25, and 2.5 wt.%) powders are mechanically activated in a high-energy planetary mill for 15 min and then sintered between 800 and 1100 degrees C for 2 h. The influence of ...
A Characterization of Ceramic SMD Inductors for PCB Applications
(IEEE, New York, 2009)
In this paper, a measurement technique, characterization and parameters extraction of SMD inductors for PCB applications are presented. These components, manufactured by Fair-Rite, are measured and characterized using a ...
Effect of chemisorbed carbon monoxide on Pt/C electrode on the mechanism of the hydrogen oxidation reaction
(Pergamon-Elsevier Science Ltd, Oxford, 2009)
The influence of poisoning of Pt catalyst by CO on the kinetics and mechanism of H-2 oxidation reaction (HOR) at Pt/C electrode in 0.5 mol dm(-3) HClO4, saturated with H-2 containing 100 ppm CO, was examined with rotating ...
Spectrofluorimetric and HPLC Determination of Morin in Human Serum
(Slovenian Chemical Society, 2009)
Morin is a flavonol antioxidant. In ethanol-water mixtures (70 wt% of ethanol) it reacts with Al3+ to give Al(Morin)(2) in the pH range 3-6. The conditional stability constant of this complex at 298 K was found to be log ...
Modifications of AISI 1045 steel by picosecond Nd:YAG laser at 266 nm; comparison with 532 and 1064 nm pulses
(Elsevier, Amsterdam, 2009)
Interaction of Nd:YAG laser, operating at 266 nm wavelength and a pulse duration of 40 ps, with AISI 1045 steel was studied. Surface damage threshold was estimated to be 0.14 J/cm(2). The steel surface modi. cation was ...
Resistive upper critical fields and anisotropy of an electron-doped infinite-layer cuprate
(Amer Physical Soc, College Pk, 2009)
We report a transport study down to 2 K and in high magnetic fields up to 20 T of a highly c-axis-oriented epitaxial thin film of electron-doped "infinite-layer" cuprate superconductor Sr1-xLaxCuO2 with T-c of 26 K. A 16 ...
Influence of MgO addition on the synthesis and electrical properties of sintered zinc-titanate ceramics
(Elsevier Science Sa, Lausanne, 2009)
Starting mixtures of ZnO, TiO(2) and MgO (0, 1.25 and 2.5 wt.% MgO) powders were mechanically activated for 15 min in a planetary ball mill. The powders obtained were sintered non-isothermally to temperatures between 800 ...
