We report a piezoelectric effect in cholesteric liquid crystalline elastomer gels. When we apply a shear stress to a cholesteric elastomer gel in the direction perpendicular to its helical axis, a polarization can be induced in the direction perpendicular to both the stress and the helix. This experimental observation…

NiZn ferrite thin films with spinel structure have been deposited successfully on glass substrates at a relatively low temperature by means of the Facing Target Sputtering (FTS) technique. In addition to substrate temperature, PO/sub 2//P (O/sub 2/ partial pressure over total sputtering pressure) ratio was found to be…

A method to calculate the low frequency complex electric field in polluted insulators is proposed. The method is based on a quasi-static approximation which permits the decoupling of Maxwell's equations. The method is implemented numerically through the finite element technique by defining a complex functional.

The third order nonlinear optical susceptibilities χ(3) of BaO-TiO2-B2O3 glasses have been measured by the third harmonic generation (THG) method. Raman spectroscopic investigation revealed that Ti4+ ions mainly exist as 4-coordinated. It was found that the addition of TiO2 to BaO-B2O3 glass increases the χ(3) as well…

Zirconium is prone to localized corrosion in acidic chloride (Cl–) solutions contaminated by oxidizing ions, such as ferric or cupric ions. This tendency can be reduced by ensuring that the zirconium surface is clean and smooth. The effect of surface condition on localized corrosion of zirconium in acidic chloride sol…
