Tolman Length (Paperback)

High Quality Content by WIKIPEDIA articles! The Tolman length (also known as Tolman's delta) measures the extent by which the surface tension of a small liquid drop deviates from its planar value.Any result for the Tolman length therefore gives information about the radius of spontaneous curvature, R0. If the Tolman length is known to be positive (with k > 0) the interface tends to curve towards the liquid phase, whereas a negative Tolman length implies a negative R0 and a preferred curvature towards the vapour phase.Apart from being related to the radius of spontaneous curvature, the Tolman length can also be linked to the surface of tension'.
