CRYSTALLINE ACCOMMODATION LAW EXPLAINS THE CRYSTALLINE STRUCTURE OF MATERIALS

Electronic Structure of Crystalline Materials

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...

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...

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...

Changes in the internal structure of the human crystalline lens with age and accommodation

Scheimpflug images were made of the unaccommodated and accommodated right eye of 102 subjects ranging in age between 16 and 65 years. In contrast with earlier Scheimpflug studies, the images were corrected for distortion due to the geometry of the Scheimpflug camera and the refraction of the cornea and the lens itself. The different nuclear and cortical layers of the human crystalline lens were...
