This latent heat can store a significant amount of energy in a material over a relatively small temperature change. This latent heat exists in solid-to-liquid phase changes as well, where it’s ...

The concept of phase-change recording is straightforward. An intense laser or current pulse heats and melts the crystalline material, which is subsequently quenched into the amorphous state.

When water freezes into ice or boils into vapor, its properties change dramatically at specific temperatures. These so-called ...

a phase change material (PCM). The study used the enthalpy-porosity approach and a local thermal non-equilibrium (LTNE) model to analyze positive and negative porosity gradients in the x and y ...

A rewritable optical disc. First used in drives by Panasonic in the late 1980s, the phase change technology was subsequently employed in all major optical drives, including CD-RW, DVD-RW ...

Scientists have uncovered a new way to explore the complex transformations of 2D nanomaterials. By using nanoscale vibrating ...

This revealed how the material's vibrations change near its phase transition temperature and, with that, its magnetic properties. "Imagine a drum with a magnetic structure, where the laser light ...

Phase change cooling creates subzero temperatures as low as -100 degrees Centigrade, but the humidity created by condensation is a side effect that has to be dealt with. Phase change cooling has ...
