Negative thermal expansion (NTE) materials exhibit the counterintuitive property of contracting upon heating. This behaviour arises in a diverse range of systems—from open‐framework oxides and ...

Cordierite, the material behind heat-resistant pizza stones, has been shown to resist changes in size despite significant temperature fluctuations. The reasons for this have been largely unexplained ...

Australian researchers have created what may be one of the most thermally stable materials ever discovered. This new zero thermal expansion (ZTE) material made of scandium, aluminum, tungsten and ...

Most metals expand when their temperature rises. This effect is extremely undesirable for many technical applications. Now, scientists have created a new material that hardly changes in length over an ...

A new material that shrinks when it is heated and expands when it is cooled could help enable the ultra-stable space telescopes that future NASA missions require to search for habitable worlds; ...
