Crystal structure and microstructure of cholesteryl oleyl carbonate
(ELSEVIER IRELAND, 2011-01)The crystal structure as well as the microstructure, i.e., size and strain, of crystallites of cholesteryl oleyl carbonate was determined from X-ray powder diffraction data. The X-ray line broadening was analyzed through ... -
Dipole-induced chiral smectic-C phase in a eutectic mixture of cholesterol esters
(ELSEVIER SCIENCE BV, 2005-07-20)Both cholesteryl oleate (CO) and cholesteryl oleyl carbonate (COC) are thermotropic mesogens with a general cooling phase sequence: isotropic cholesteric -> smectic crystal. They are almost identical with respect to molecular ... -
Isotropic to nematic phase transition in F-actin
(Elsevier B.V, 2007)Like a few other rod-like and semi-rigid polyelectrolytes, filamentous actin (F-actin) shows, respectively, an isotropic to nematic (I-N) phase transition and an aggregation to a hexagonal liquid crystal followed by ... -
Pretransitional phenomena in pure states and in a binary mixture of axially and transversàlly dipolar rodlike molecules of near-identical structures
(ISSST, 2009)Mesophase induction generates strong smectic pretransitional fluctuations in the first three phases of a thermotropic polymorphism: Isotropic → Cholesteric → Chiral Smectic-A → Chiral Smectic-C → Chiral Hexatic Smectic → ... -
Ultraviolet-visible-near infrared and mid-Fourier transform infrared spectroscopic studies of intermolecular interaction in cholesteryl oleyl carbonate in mesophases
(AMER INST PHYSICS, 2006-03-28)Ultraviolet-visible-near infrared (UV-Vis-NIR) and Fourier transform infrared (FTIR) spectroscopic studies are presented of molecular association between like molecules of cholesteryl oleyl carbonate, each containing ... -
