Phase transitions, shifts between different states of matter, are widely explored physical phenomena. So far, these ...

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 ...

A new study that provides unprecedented insights into the chemical bonding of antimony could have a profound impact on materials research. The collaboration between scientists from Leipzig University, ...

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 ...

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 ...

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 ...

If ever there were a wake-up call, this is it. The fire alarm is ringing – hell, the fire alarm is on fire. The latest data confirms that 2024 was the first year in which the average global ...

This has important implications for the understanding of phase change materials, which are used in data storage and thermoelectrics, among other applications. Antimony as a model for phase change ...

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, ...
