When the search for habitable exoplanets requires a 1,000 times more stable telescope than James Webb Space Telescope, even minimal material expansion down to a fraction of the width of an atom is the ...

A new material called Alloy 30 shrinks when it is heated and expands when it is cooled and it could help with telescope ...

Because it shrinks when other materials expand, Allvar Alloy 30 can be used to strategically compensate for the expansion and ...

Superinsulating aerogel resists mechanical and thermal shocks. Creating composites with near-zero thermal expansion. NTE materials mixed with a PTE material in composites that have near-zero thermal ...

This new zero thermal expansion (ZTE) material made of scandium, aluminum, tungsten and oxygen did not change in volume at temperatures ranging from 4 to 1,400 Kelvin (-269 to 1126 °C, -452 to ...
