Majority of materials are focus to thermal expansion which means to expand when heated and to contract when cooled. But thermal expansion can also be useful, making possible the workings of ...
Materials with negative linear compressibility are sought for various technological applications. Such effects were reported mainly in framework materials. When heated, they typically contract in the ...
Most materials expand when heated. A few, such as water just above freezing, contract. Now, for the first time, physicists have found a material that switches from expanding to contracting in the ...
