A phase transition between a stable monolayer phase and a stable three-layer phase of the liquid crystal film was detected during further monolayer compression.doi:10.1016/S0040-6090(96)08984-5Mitsumasa IwamotoTohru KubotaMuhamad Rasat Muhamad...
DSC measurements on p- n -hexyloxybenzylidine-p′- n -butylaniline (6O.4) showed that the crystalline to liquid crystalline ( K - S H ) transition at 33.7°C observed in the heating cycle does not revert even when the sample is cooled down to 100°C. Hence it is inferred that a ...
The liquid crystal cell used a cholesteric-nematic mixture with positive dielectric anisotropy (CN cell) has a cholesteric phase at the off-state when molecules of liquid crystals near the electrode surfaces were aligned perpendicular to them by using surface treatment. The cholesteric phase at the ...
Miscibility appears to be enhanced by the flexibility of the parent compounds and dipole-dipole interaction: it is characterized by decreased transition temperatures and stabilized phases.doi:10.1080/10587250108028257Singh, UpindranathDavis, Fredric
We present here the first study of the use of a pressure-jump to induce the ripple (P beta')/lamellar liquid crystal (L alpha) phase transition in fully hydrated 1,2-dimyristoyl-sn-glycero-3-phosphocholine (DMPC). The transition was monitored by using time-resolved x-ray diffraction (TR...
Liquid crystal elastomers hold promise in various fields due to their reversible transition of mechanical and optical properties across distinct phases. However, the lack of local phase patterning techniques and irreversible phase programming has hindere
A liquid–liquid transition in supercooled water has long been predicted. State-of-the-art simulations now precisely confine the temperature and pressure ranges for this transition, which are found to be within experimental reach. F. Sciortino ...
2) Liquid crystal phase transition 液晶相变 例句>> 3) crystalline phase transformation 晶相转变 1. The PVDF has the crystalline phase transformation in these methods. 利用固相法制备了掺杂有Nb2O5的PZT95/5压电陶瓷,采用固化、冷等静压、溶液混合法制备0-3型PZT/PVDF压电复合材料,经过对这几种...
Dielectric studies of first order phase transition feroelectric liquid crystal, having the phase sequence of chiral nematic to smectic C* phase have been performed in the frequency range of 10Hz to 10MHz in thin(3.5渭m) cells. The dielectric processes have been reported in planar and homeo...
phase transitiontetramersWe synthesized novel liquid crystal tetramers possessing cyanobiphenyl and phenylpyrimidine moieties, and investigated their phase transition behavior. The liquid crystal tetramers exhibited nematic (N) and smectic A (SmA) phases. X-ray diffraction measurements suggest that the SmA...
