Study of the lignin model compound supramolecular structure by combination of near-field scanning optical microscopy and atomic force microscopy
(Elsevier, Amsterdam, 2004)
In this paper, we present a nanoscale study of the supramolecular structure of the dehydrogenate polymer (ZL-DHP) lignin model compound. The combination of near-field scanning optical microscopy (NSOM or SNOM) and atomic ...
Mechanochemical synthesis of CaTiO3 from CaCO3-TiO2 mixture
(Trans Tech Publications Ltd, 2004)
The synthesis of calcium titanate, CaTiO3, was performed by mechanical activation and thermal treatment. Milling for up to 360 minutes in a planetary ball mill mechanically activated an equimolar mixture of CaCO3 and TiO2 ...
Photoacoustic properties of sintered NiO
(Carl Hanser Verlag, Munich, 2004)
The thermal diffusivity of NiO pellets was determined by the photoacoustic technique. A NiO powder, with a purity of 99.95%, was pressed into pellets 10 mm in diameter. The average agglomerate size of the NiO powder was ...
Distribution of the Asiatic cyprinid Pseudorasbora parva in Serbia and Montenegro
(Wiley, Hoboken, 2004)
The first record of Pseudorasbora parva in the Balkan region was in 1977 in Sasko Lake, Montenegro and in 1978 it was found in Serbia. Since then, this species has spread to almost all lowland rivers and has become a ...
A phenomenological analysis of sintering kinetics of alumina
(Trans Tech Publications Ltd, Durnten-Zurich, 2004)
In this paper a phenomenological analysis of the sintering kinetics of alumina powder compacts with different proportions of small and large particles has been made. A phenomenological approach enables definition of ...
Estimation of neuronal population activity changes in rat cerebellum using one electrode
(Elsevier Science Inc, New York, 2004)
Activity of neuronal populations is usually measured with multielectrode systems. In this paper a procedure is described for estimating population activity changes in rat cerebellar cortex, using one microelectrode. Signals ...
Influence of the common varistor dopants (CoO, Cr2O3 and Nb2O5) on the structural properties of SnO2 ceramics
(Elsevier Science Inc, New York, 2004)
The influence of dopants commonly used in SnO2 varistor ceramics, such as CoO, Cr2O3 or Nb2O5, on the structural properties of SnO2 was investigated. Several SnO2-based ceramics containing only one of the dopants were ...
Dielectric and piezoelectric properties of the mechanochemically prepared PZT ceramics
(Springer, New York, 2004)
Mechanochemical synthesis was applied to obtain nanocrystalline powders of composition Pb(Zr0.52Ti0.48)O-3 (PZT). Milling was performed in a planetary ball mill using vials and balls made of zirconia or steel-in order to ...
Strontium titanate films prepared by spray pyrolysis
(Elsevier Sci Ltd, Oxford, 2004)
Strontium titanate thin films were prepared by spray pyrolysis technique. Deposition parameters, such as solution concentration, time and temperature of deposition, and flow rate of carrier gas were optimized to obtain ...
Photoacoustic properties of sintered NiO
(Walter De Gruyter Gmbh, Berlin, 2004)
The thermal diffusivity of NiO pellets was determined by the photoacoustic technique. A NiO powder, with a purity of 99.95 %, was pressed into pellets 10 mm in diameter. The average agglomerate size of the NiO powder was ...
