Segmented thermistors printed by NTC nanometric paste and applied in volume air-flow sensors
(Materials Science Forum, 2006)
An investigation path starting from (Mn,Ni,Co,Fe)3O4 nanometric powder preparation, NTC thick-film characterization, realization and optimization of new planar thermistor geometries to custom design thermistors and their ...
Further guaianolides from Amphoricarpos neumayeri ssp murbeckii from Montenegro
(Verlag Z Naturforsch, Tubingen, 2006)
The aerial parts of Amphoricarpos neumayeri ssp. murbeckii afforded eleven guaianolides with the same relative (1 alpha H,4 beta H,5 alpha H, 7 alpha H) configuration of the basic skeleton. All of them contained a CH2OX ...
Hydrogen evolution on Ni/WC composite coatings
(Springer, 2006)
The catalytic activity for the hydrogen evolution reaction (HER) of Ni/WC composites obtained by electrochemical
deposition of nickel from a conventional Watt’s bath, using two different ways of depositing the WC particles, ...
Phytochemical investigation of Anthemis cotula / Фитохемијско испитивање биљне врсте Anthemis cotula
(Serbian Chemical Society, 2006)
The investigation of roots of Anthemis cotula (Asteraceae) from east Serbia revealed, in addition to polyacetylenes previously isolated from the same species, three prenylated 4-hydroxyacetophenones, detected for the first ...
Electrocatalytic Activity of Sol–Gel-Prepared RuO 2 /Ti Anode in Chlorine and Oxygen Evolution Reactions
(Springer, 2006)
Electrocatalytic properties of
RuO
2

Activity of a PtBi alloy in the electrochemical oxidation of formic acid
(Elsevier, 2006)
Formic acid oxidation in acid solution was examined on a PtBi alloy characterized by X-ray photoelectron spectroscopy. Three chemical states of Bi, i.e., PtBi or Bi(0), Bi2O3 and BiO(OH) were found. Electrochemical ...
Factors affecting the microstructure of porous ceramics / Faktori koji utiču na mikrostrukturu porozne keramike
(Serbian Chemical Society, 2006)
In this study, porous ceramics were produced by using two methods: the polymeric sponge and foam method. A study of the effect of viscosity on the characteristics of the final product produced using the polymeric sponge ...
The cellular fatty acid composition of Bradyrhizobum japonicum and Sinorhizobium meliloti strains / Ćelijske masne kiseline sojeva Bradyrhizobum japonicum i Sinorhizobium meliloti
(Acta biologica iugoslavica - serija B: Mikrobiologija, 2006)
Microbial fatty acid analysis represents a simple and rapid method for identification of strains mainly for taxonomic purpose. Fatty acid composition in the whole cells and lipopolysaccharides in Rhizobiaceae were studied ...
Porous poly(methylmethacrylate) and poly(methylmethacrylate-co-acrylamide) / Porozni poli(metilmetakrilat) i poli(metilmetakrilat-co-akrilamid)
(Association of Chemical Engineers of Serbia, 2006)
The characteristics of two types of porous polymers: poly(methyl methacrylate) and copolymers of methyl methacrylate and acrylamide were investigated in this study. Poly(methyl methacrylate) was synthesized in suspension, ...
Textural and fractal properties of CuO/Al 2 O 3 catalyst supports
(Elsevier, 2006)
Reactive amorphous aluminas with a high surface area, suitable as a precursor for catalyst supports, are obtained by flash calcination of gibbsite in a reactor for pneumatic transport in the dilute two phase flow regime. ...
