Phase transitions in crystalline materials

We reviewed structural phase transitions in crystalline materials, especially recent simulations and experiments on the shock-induced transitions in iron. They both confirmed a phase transition wave in the picosecond to nanosecond time scale, inferred previously from wave profile analyses. The nonequilibrium molecular dynamics simulation suggests modification of pair potentials from temperature...

Diffusion in porous crystalline materials.

The design and development of many separation and catalytic process technologies require a proper quantitative description of diffusion of mixtures of guest molecules within porous crystalline materials. This tutorial review presents a unified, phenomenological description of diffusion inside meso- and micro-porous structures. In meso-porous materials, with pore sizes 2 nm < d(p) < 50 nm, there...

Electronic Structure of Crystalline Materials

n liquid crystalline elastomer materials

Liquid crystalline elastomers (LCEs) exhibit a number of remarkable physical effects, including the unique, high-stroke reversible mechanical actuation when triggered by external stimuli. This article reviews some recent exciting developments in the field of LCE materials with an emphasis on their utilization in actuator applications. Such applications include artificial muscles, industrial man...

Spinodal decomposition in liquid crystalline materials

The theory of phase separation m a liquid crystal by spinodal decompoSit1on is developed The time evolution of two coupled parameters, the volume concentration (or mole fraction), and the orientational order parameter is calculated The conditions for penodic fluctuations are gJven and the structure factor for spinodal decomposition is studied
