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 ...

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 ...

The remarkable framework flexibility is one of the most important advantages of porous coordination polymers (PCPs) or metal–organic frameworks, which allows the host structures to be altered by ...

Most materials expand when they are heated, but some contract instead. A record value of this effect — known as negative thermal expansion — has now been observed in magnetic nanocrystals. Controlling ...
