Using the Landau-Ginzburg-Devonshire approach, we study stress-induced transformations of polarization switching in ferrielectric CuInP2S6 nanoparticles for three different shapes: a disk, sphere, and needle. Semiconducting properties nanoparticle are modeled by surface charge layer, whose effective screening length can be rather small due to field-effect. We reveal very strong unusual influenc...

The electroactive polymer polyvinylidene fluoride (PVDF) has gained much interest in smart materials research with a wide application range for industry and consumer applications due to the low cost, flexibility, chemical resistance, non-toxicity, light weight. In this work, we present an α-phase PVDF cantilever that exploits electrostriction as main transducer mechanism excitation. We realize ...

A theoretical study of the polarization distribution and mechanical stresses in a ferroelectric ball located an unlimited dielectric space has been carried out. The is covered with air shell. external electric field far from assumed to be uniform. satisfies nonlinear Landau--Ginzburg equation, which takes into account presence electrostriction. It also that for small ball, effect local elastic ...

The mechanism(s) responsible for the breakdown (nanoporation) of cell plasma membranes after nanosecond pulse (nsEP) exposure remains poorly understood. Current theories focus exclusively on the electrical field, citing electrostriction, water dipole alignment and/or electrodeformation as the primary mechanisms for pore formation. However, the delivery of a high-voltage nsEP to cells by tungste...
