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 ...

Most metals expand when their temperature rises. The Eiffel Tower, for example, is about 10 to 15 centimeters taller in summer than in winter due to its thermal expansion. However, this effect is ...

Most materials in our world shrink in volume when cooled and expand when heated. Humans have known this for some time, and have built our civilization with that in mind. Yet, as we seek to expand ...

Cordierite, a remarkable mineral familiar to many as the material behind heat-resistant pizza stones, exhibits an unusual ability to resist changes in size despite significant temperature fluctuations ...

Company Allvar working with NASA on NTE space telescope optics; other applications are possible. A new material that shrinks when it is heated and expands when it is cooled could help enable the ultra ...

In both residential and commercial buildings, heating and cooling cycles can take a toll on piping systems. When pipes expand due to heat and contract when they cool, they stress joints, supports, and ...
