"When it's added to a polymer, it causes that polymer to contract less, hitting expansion and contraction values similar to metals. To have a molecule that behaves like metal is pretty remarkable." ...

VELOCE observations trace the expansion and contraction of Cepheid stars with unprecedented precision. On the left: observed spectra of the Cepheid archetype Delta Cephei as they change in wavelength ...

Almost every material expands when heated. Well-known examples include railroad tracks and concrete roadways, which feature visible expansion gaps to accommodate this effect. However, thermal ...
