The change in temperature of a body causes expansion or contraction of that body. Most of the substances expand on heating and contract on cooling. This is called thermal expansion. It has been ...

Thermal expansion properties of solids are of fundamental interest and control of thermal expansion is important for practical applications but can be difficult to achieve. Many framework-type ...

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 ...

The distances between particles are smallest in the solid, they are larger in the liquid and larger again in the gas. The particles in gases and liquids move more freely than in solids, so their ...

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 ...
