phase-change processesStefan problemsanomalous diffusionCaputo derivativeWe review some fractional free boundary problems that were recently considered for modeling anomalous phase-transitions. All problems are of Stefan type and involve fractional derivatives in time according to Caputo's definition. We ...
Phase-change memory utilizing amorphous-to-crystalline phase-change processes for reset-to-set operation as a nonvolatile memory has been recently commercialized as a storage class memory. Unfortunately, designing new phase-change materials (PCMs) with low phase-change energy and sufficient thermal ...
Study of the phase change processes of encapsulated phase change material for solar thermal energy storage in domestic hot water production This study aims to examine the melting processes of encapsulated PCM in a cylindrical-shaped capsule, made of stainless steel. It has a diameter of 60 mm a...
support of fundamental research targeting NASA's long range missions goal have identified several phase change processes needed to design advanced space and planetary based systems for long duration operations Recommendation noted that phase change processes are profoundly affected by gravitational environment...
Switchable optical transparency is an intrinsic property for solid–liquid phase change materials (PCMs) during phase change processes. However, due to non-transparent porous confinement materials and core-shell structures, the synthesis of shape-stabled PCMs typically sacrifices their switchable optical ...
ePCM presents a solution to these chip- and system-level challenges, while meeting automotive requirements for AEC-Q100 Grade 0, operating at temperature up to +165°C. In addition, ST’s technology assures firmware/data retention through high-temperature soldering reflow processes and immunity to ...

The crystalline, liquid and amorphous phase stabilities and transformations of the Ge1Sb2Te4 (GST124) alloy are investigated as a function of pressure and temperature using synchrotron diffraction experiments in a diamond anvil cell. The results indicate that the solid-state amorphization of the ...
