Crystalline solid retains memory of anisotropy in precursor liquid crystalline phase

Photoinduced phase transitions in liquid crystalline systems

In recent years, a field of research that is growing steadily is the photoinduced phenomenon in which the incident light itself brings about molecular ordering/ disordering of the liquid crystalline system. This particular aspect of photonics, in which light can be controlled by light as a stimulus, is being proposed as the future technology for high-speed information processing and photochromi...

Finding transition states for crystalline solid-solid phase transformations.

We present a method to identify transition states and minimum energy paths for martensitic solid-solid phase transformations, thereby allowing quantification of the activation energies of such transformations. Our approach is a generalization of a previous method for identifying transition states for chemical reactions, namely the climbing image-nudged elastic band algorithm, where here the glo...

Kinetics of the crystalline-liquid crystalline phase transition of dimyristoyl L-alpha-lecithin bilayers.

Aqueous dispersions of synthetic dimyristoyl L-alpha-lecithin undergo a sharp decrease in turbidity in the temperature range where the crystalline-liquid crystalline phase transition occurs. Equilibrium transition curves, monitored by the absorbancy change at 300 nm, reproduce all the important features of a calorimetric melting curve [Hinz & Sturtevant (1972) J. Biol. Chem. 247, 6071]. A rapid...

Liquid-crystalline terpyridines.

5,5"-Disubstitution of the terpyridine core leads to the first inherently liquid-crystalline terpyridines. Mesophases characteristic of bent-core and calamitic systems may be obtained depending on the core structure employed.
