Effect of Humidity on Liquid-Crystalline Myelin Figure Growth Using Digital Holographic Microscopy
(Elsevier B.V., 2016)Dynamics of liquid-crystalline Myelin Figures (MFs) is a multifaceted issue depending on various elements, which have not been fully resolved yet. Our experimental results show that degree of humidity is influential on the ... -
Effects of ions on the liquid crystalline mesophase of transition-metal salt: surfactant (CnEOm)
(American Chemical Society, 2004)The transition-metal aqua complex salts [M(H2O) x]Y2 (where M is some of the first- and second-row transitionmetal ions and Y is Cl-, NO3-, and ClO4- counteranions) form liquid crystalline (LC) mesophases with oligo(ethylene ... -
Liquid crystalline mesophases of pluronics (L64, P65, and P123) and transition metal nitrate salts ([M(H2O)6](NO 3)2)
