TL;DR: It is demonstrated that reversible photoisomerization gratings recorded in a non-photorefractive azo-based material exhibit large optical gain coefficients beyond 1,000 cm(-1), even for polarization gratings.
Abstract: Organic holographic materials are pursued as versatile and cheap data-storage materials. However, previously such materials either needed the application of an external electric field or had mostly poor efficiencies. Now, a novel recording process based on a photoisomerization process demonstrates significantly improved writing properties of holograms.

TL;DR: In this paper, a new approach to computational homogenization in dissipative electro-mechanics based on a rigorous exploitation of rate-type and incremental variational principles, governing the scale bridging between micro- and macroscales is proposed.

TL;DR: Shape-memory alloys are capable of undergoing reversible phase transitions as a result of temperature, pressure, or other stress-related changes as mentioned in this paper, and they exhibit a mechanical type of shape memory called pseudoelasticity and, under certain conditions, linear superelasticity.
Abstract: Shape-memory alloys are capable of undergoing reversible phase transitions as a result of temperature, pressure, or other stress-related changes. These materials exhibit a mechanical type of shape memory called pseudoelasticity and, under certain conditions, linear superelasticity. The recoverable strain or shape is generally . Whereas the alloys are primarily nonferrous, some ferrous alloys also exhibit shape memory.
Applications of shape-memory alloys include those as tubes and valves in piping systems for power plants, ships, and the petroleum industry; use as explosive bolts in the aerospace and construction industry; as packaging devices for electronic materials; and as dental materials, prosthetics, and biomedical devices. Shape-memory alloys may be found in sensors in automobiles, in consumer products, and generally in smart materials and adaptive structures.
