Phase change materials are proving to be a useful tool to store excess energy and recover it later – storing energy not as electricity, but as heat. Let’s take a look at how the technology ...

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. To ...

Developed by Stanford Ovshinsky, reknowned for his inventions in memories and solar panels, "phase change RAM" (PRAM, PCRAM) and "chalcogenide RAM" (C-RAM) are other names for phase change memory ...

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 ...

Phase change materials (PCM) are already used for basic energy storage, in reducing heat losses, increasing heat storage, controlling temperature changes, and controlling spaces' temperature. However, ...

After decades of looking, researchers have seen a string of atoms go through a 1D phase change so elusive that it could only happen inside a quantum simulator. “One motivation [for our ...

Scientists in Iraq have applied two different kinds of phase-change materials to lower the operating temperatures of PV panels. Their experiment showed that beeswax and paraffin wax are ...

Ritesh Agrawal poses with some of the equipment used in studying the new process, which dramatically lowers the energy cost of amorphization, bringing phase-change memory devices closer to ...

This whitepaper explores the use of two-phase cooling (2PD2C), which uses a different coolant with a low boiling point, ...
