The Gibbs Thomson effect (also called the Gibbs Kelvin effect or Kelvin effect) relates surface curvature to vapor pressure and chemical potential and is a consequence of surface tension. It is named after Josiah Willard Gibbs and William Thomson, 1st Baron Kelvin. (It is not to be confused with the thermoelectric Thomson effect.) It leads to the fact that small liquid droplets (i.e. particles with a high surface curvature) exhibit a higher effective vapor pressure, since the surface is larger in comparison to the volume. The Gibbs Thomson effect can cause strong depression of the freezing poi...

The Gibbs Thomson effect can cause strong depression of the freezing point of liquids dispersed within fine porous materials.
