In this research, the author proposed a supercooling phenomenon reduction PCM that suppresses decrease in latent heat by installing with small degree on transfer surface side of large degree. As result, it was shown can reduce forming and growing solidified crystals even when temperature is higher than release temperature. Furthermore, calculation results for predicting cooling heating characte...

Abstract We demonstrate a multilevel optical memristive switch based on silicon Fabry–Perot resonator. The resonator is constructed by pair of waveguide Bragg gratings at the ends multimode interferometer (MMI) covered with sub-micrometer-size Ge 2 Sb Te 5 (GST) thin film top. interaction between field and GST greatly enhanced due to resonant effect. phase transition triggered applying electric...

Efficient, cost effective, and stable high-temperature heat storage material systems are important in applications such as high-temperature industrial processes (metal processing, cement and glass manufacturing, etc.), or electricity storage using advanced adiabatic compressed air energy storage. Incorporating phase change media into heat storage systems provides an advantage of storing and rel...

The macroscopic model of solid-solid phase change presented makes use of internal variables to represent the phase fractions and the local strains. As such, it can be cast in the framework of standard materials with internal constraints. These constraints are accounted for by Lagrange's multipliers. Reversible or irreversible phase changes are considered in a general way. Material stability is ...

Microand nano-mechanical systems may take advantage from using materials having multiple functional characteristics. VO2 is a compound characterised by a solid state phase transition (SSPT) just above room temperature, consisting in a concurrent metal-insulator transition and a change of lattice symmetry and parameters. Here, the combination of non-linear electrical response and structural chan...
