It can be a lightweight way to increase the thermal mass of a building, and can reduce the reliance on active cooling or heating from HVAC systems. BioPCM brand phase-change material installed in ...

The concept of phase-change recording is straightforward. An intense laser or current pulse heats and melts the crystalline material ... that on rather slow cooling of the melt, the crystalline ...

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 ...

The metafilm is based on the phase change material GST and metal Mo. For the optical properties of GST change dramatically in different states, the infrared radiation characteristics of the target ...
