Researchers have long studied materials with negative thermal expansion (NTE), where substances shrink as they heat up. These materials, found in oxides, fluorides, and certain metal alloys ...

In an ultra-cold, high-magnetic-field setting, ZrTe5 defies expectations by showing quantum heat oscillations. Researchers ...

They placed powdered metal between these jaws, heated it up to 400°C until it formed a droplet, then crushed it at an enormous pressure of up to 200 megapascals. The metal was compressed until it ...
