Phase Change Material (PCM) is a substance that helps regulate your sleep temperature by acting as an in-bed heat reservoir. In mattresses, PCM tends to be in wax or gel form.

They used paraffin wax as the phase-change material (PCM), incorporating various levels of aluminum oxide (Al₂O₃) and zinc oxide (ZnO) nanoparticles. They also developed a prediction model.

In experiments, the system was quite effective – the material changed its temperature by 25 °C (45 °F) under as little as 0.22 volts, which is far greater than other phase-change cooling systems.

As a result, they demonstrated that the metastable phase was thermodynamically stable, identified the 3D structure of metastable-phase crystals, and suggested a new nanoparticle growth mechanism ...

Incorporating a phase-change material into concrete, this self-heating material can melt snow and ice for up to 10 hours without any help. The novel product could reduce the need for plowing and ...

Slow and Steady Overall, the treated lightweight aggregate slab performed better at sustaining its heating — keeping the temperature above freezing for up to 10 hours — while the slab with ...
