High-Temperature Dielectric Response of (1-x)Pb(Mg1/3Nb2/3)O3-xPbTiO3: Does Burns Temperature Exist in Ferroelectric Relaxors?

open access: yes, 2010
It has been considered that polar nanoregions in relaxors form at Burns temperature Td approx 600 K. High-temperature dielectric investigations of Pb(Mg1/3Nb2/3)O3 (PMN) and 0.7PMN-0.3PbTiO3 reveal, however, that the dielectric dispersion around 600 K ...

A Close Look at the Local Structure of Functional Polymers: The Example of Poly(Vinylidene Fluoride)

open access: yesAdvanced Functional Materials, EarlyView.
To accurately develop structure‐property relationships in functional macromolecules, it is increasingly important to consider the local chain arrangement in addition to long‐range order. It is demonstrated in the case of poly(vinylidene fluoride) that solid‐state nuclear magnetic resonance (NMR) spectroscopy can provide detailed insights into the local

Conditions for non-stationary discharge initiation into "burning-through" mode [PDF]

open access: yesarXiv, 2003
The special form of an electric discharge - "burn-through" in regard to the ball lightning problem has been considered. Having been carried out within closed volume, this mode of erosive discharge has shown the series of clear differences consisting in the high gas density, formation of the metal-polymer aerogel, the percolating current and unusual ...
