Amorphous-to-Quasicrystalline Transformation in the Solid State
Physical Review Letters, 1985${\mathrm{Al}}_{84}$${\mathrm{Mn}}_{16}$ multilayer films have been amorphized by room-temperature ion-beam irradiation. The amorphous phase was transformed into the quasicrystalline state through two routes: thermal and ion-beam-assisted thermal. The intensity of the quasicrystalline electron diffraction increases continuously with annealing between ...

Transition state analysis of solid-solid transformations in nanocrystals
The Journal of Chemical Physics, 2009A systematic simulation methodology is introduced for the accurate determination of experimentally measurable quantities characterizing solid-solid phase transformations under pressure. The atomistic mechanisms of nucleation and growth in a structural transformation of pressurized CdSe nanocrystals are identified using transition path sampling computer

Solid–Liquid State Transformable Magnetorheological Millirobot
ACS Applied Materials & Interfaces, 2022Magnetically actuated soft millirobots (magneto-robot) capable of accomplishing on-demand tasks in a remote-control manner using noninvasive magnetic fields are of great interest in biomedical settings. However, the solid magneto-robots are usually restricted by the limited deformability due to the predesigned shape, while the liquid magneto-robots are

Abstract Eutectoid and peritectoid transformations are classified as solid-state invariant transformations. This article focuses primarily on the structures from eutectoid transformations with emphasis on the classic iron-carbon system of steel. It reviews peritectoid phase equilibria that are very common in several binary systems.

Soft-switching solid state transformer (S4T)
2016 IEEE Energy Conversion Congress and Exposition (ECCE), 2016This paper presents a new topology for a fully bidirectional soft-switching solid state transformer (S4T). The minimal topology, featuring 12 main devices and a high-frequency transformer, does not use an intermediate DC voltage link, and provides sinusoidal input and output voltages. The S4T can be configured to interface with two-or multi-terminal DC,

Auxiliary power supply for solid state transformers
2016 IEEE International Conference on Electronics, Circuits and Systems (ICECS), 2016This paper discusses different ways to obtain an auxiliary power supply (APS) to a solid state transformer (SST) that utilizes the modular AC-DC-DC-AC configuration. A local distributed source, that consists of two APS per module, one for medium voltage (MV) side and another one for low voltage (LV) side is proposed.
