Equivalence Between 2-Dimensional and 3-Dimensional Phases of Aliphatic Chain Derivatives
We demonstrate a detailed structural equivalence between 7 of the 12 known condensed water-surface monolayer phases of long-chain fatty acids and 7 of the 11 known bulk solid phases observed in long-chain alkranes. Two second-order phase transitions are common to both. Thermodynamic parameters are established in both systems for one of these and they are consistent with the proposed equivalence.
