Liquid Crystalline Structures Occurring in Aqueous Systems of a Totally Fluorinated Fatty Acid and S often lamellar but other structures may occur. The present report deals with X-ray diffraction studies at room temperature mainly of the lamellar phases existing in the binary system of heptadecafluorononanoic acid (C.F.COOH) and water, and in the corresponding systems of some of its salts, the cou苦笑 发表于 2025-3-23 14:28:09
Water 2H anD 17O NMR in Dodecylammonium Chloride/D2O Lyotropic Mesophasesgs of these nuclei, two different phases, which are macros-copically oriented by the magnetic field, have been detected: lamellar and lyotropic nematic. The latter appears only at low surfactant concentrations as an intermediate between the micellar medium and the lamellar phase. The evolution of qu预示 发表于 2025-3-23 20:36:19

31P and 2H NMR Studies of Phase Equilibria in the Three Component System: Monoolein-Dioleoylphosphater. The isothermal phase diagram shows the existence of four one-phase areas containing homogeneous liquid crystalline matter and one area with isotropic solution. Two of the liquid crystalline phases have a lamellar structure, one has a cubic and the fourth a reversed hexagonal structure. A non-aqulargesse 发表于 2025-3-24 11:28:36
Micelle Formation and Phase Equilibria of Surface Active Components of Woodigh concentrations of oleate, rod-shaped micelles are formed. Addition of salt causes the oleate micelles to grow while the abietate micelles remain small. Abietate and oleate when mixed in roughly equimolar proportions form small mixed micelles that remain soluble at much higher salt concentrationsObligatory 发表于 2025-3-24 16:10:39
