TL;DR: This work demonstrates a route to a lead-free ferroelectric for nonvolatile memories and electro-optic devices.

TL;DR: Electric field–dependent studies show that a tetragonal-like phase can be reversibly converted into a rhombohedral- like phase, accompanied by measurable displacements of the surface, making this new lead-free system of interest for probe-based data storage and actuator applications.

TL;DR: This work demonstrates that a single experimental parameter, strain, simultaneously controls multiple order parameters and is a viable alternative tuning parameter to composition for creating multiferroics.

TL;DR: A hybrid technology that integrates key aspects of both engineering disciplines is described, demonstrating the fabrication of tubes, solid nanowires, coaxial heterojunctions, and longitudinally patterned structures composed of metals, single-crystal semiconductors, and polycrystalline elemental or compound semiconductor within microstructured silica optical fibers.

TL;DR: In this paper, the use of elastic strain to enhance ferroics is discussed, which can be used to enhance the properties of known ferroic oxides or to create new tunable microwave dielectrics with performance that rivals that of existing materials.
