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 ...
Characterization of carbon cryogel synthesized by sol-gel polycondensation and freeze-drying
(Carbon, 2004)
Resorcinol-formaldehyde (RF) cryogels were synthesized by sol-gel polycondensation of resorcinol with formaldehyde and freeze-drying was carried out with t-butanol. Carbon cryogels were obtained by pyrolyzing RF cryogels ...
Electrochemically deposited Ni+WC composite coatings obtained under constant and pulsating current regimes
(Netherlands : Kluwer Academic Publishers, 2004)
A series of Ni+WC composite coatings were obtained by electrodeposition on a rotating disc electrode (RDE)from a commercially available Watts bath containing additives for brightness and smoothing and insoluble WCparticles, ...
Dielectric and piezoelectric properties of the mechanochemically prepared PZT ceramics
(Kluwer Academic Publishers, 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 ...

The Influence of Low-temperature Plasma Treatment on Hemp Fabric Dyeability
(American Institute of Physics, Melville, 2004)
Low-temperature plasma treatment of hemp fabric causes an increase of dyeing rate, final dye exhaustion and Kubelka-Munk values of dyed samples. The positive effect of plasma treatment is more prominent in case of dyeing ...
