Mechanism of phase formation in Pb(ZrxTi1-x)O3 synthesized by a partial oxalate method
(1996-06-01)
The phase formation mechanism, as well as the morphotropic phase boundary, of lead zirconate titanate (PZT) processed by a partial oxalate method was investigated by simultaneous thermal analysis (TG-DTA) and by qualitative ...

Influence of the processing conditions and corona poling on the morphology of β-PVDF
(2005-12-01)
The α → β phase transformation of PVDF through the stretching process at different temperatures was investigated. The optimum stretching conditions were studied and characterised by infrared spectroscopy and differential ...

Stability and finite element approximation of phase change models for natural convection in porous media
(2019-11)
In this paper we study a phase change problem for non-isothermal incompressible viscous flows. The underlying continuum is modelled as a viscous Newtonian fluid where the change of phase is either encoded in the viscosity ...
F region plasma density estimation at Jicamarca using the complex cross‐correlation of orthogonal polarized backscatter fields
(American Geophysical Union, 2004-06-16)
The differential‐phase method for Jicamarca F region density measurements has been modified to fit the real and imaginary components of the cross‐correlation of orthogonally polarized radar returns. The original method ...
Preparation and characterization of BaBi2Nb2O9(BBN) ceramics synthetized by polymeric precursors method
(2001-01-01)
Pure BBN powders and with addition of 1 and 2 wt% in excess of bismuth were obtained by Pechini Method. The powders calcined at 300°C/4h were analyzed by TG/DTA to study the temperature of organic matter decomposition. A ...
