Most solids expand when heated, a familiar phenomenon with many practical implications. Among the rare exceptions to this rule, the compound zirconium tungstate stands out by virtue of the enormous ...

Thermomechanical analysis (TMA) is a thermal analysis technique that measures dimensional changes at a micrometer scale, such as deformation, in a material’s properties against time or temperature ...

Thermal decomposition involves the breaking down of solid materials into simpler substances as a result of heating, and its in-depth kinetic analysis is vital for elucidating reaction mechanisms, ...

Scientific American is part of Springer Nature, which owns or has commercial relations with thousands of scientific publications (many of them can be found at www ...

When things heat up, most solids expand as higher temperatures cause atoms to vibrate more dramatically, necessitating more space. But some solid crystals, like scandium fluoride, shrink when heated — ...

In a major advancement, researchers have demonstrated negative thermal expansion with a large coefficient of −14.4(2) × 10-6 °C-1 in oxygen-redox (OR) active materials, offering new possibilities for ...

WEST LAFAYETTE, Ind. — A solid can serve as a medium for heat and sound wave interactions just like a fluid does for thermoacoustic engines and refrigerators – resulting in leak-free machines that can ...
