Field-induced phase transition in Pb(Zn1/3Nb2/3)O3–8%PbTiO3 was investigated by measuring temperature dependence of the dielectric constant under the DC biasing field. It was revealed that a critical end point (CEP) exists at 170 ± 2°C and 1.5 ± 0.2 kV cm−1. The boundary between the ferroelectric and the paraelectric…

Despite widespread use of silk, it remains a significant challenge to fabricate fibers with properties similar to native silk. It has recently been recognized that the key to tuning silk fiber properties lies in controlling internal structure of assembled β-sheets. We report an advance in the precise control of silk f…

Relaxor ferroelectrics were discovered in the 1950s but many of their properties are not understood. In this review, we shall concentrate on materials such as PMN (PbMg1/3Nb2/3O3), which crystallize in the cubic perovskite structure but with the Mg ion, charge 2+, and the Nb ion, charge 5+, randomly distributed over t…
