Corinthian order perhaps reduced in size and importance, scrolling out above the two ranks of stylized acanthus leaves and stalks ("cauliculi" or "caulicoles"), eight in all, and to notice that smaller volutes scroll inwards to meet each other on each side. The leaves may be quite stiff, schematic and dry, or they may be extravagantly drilled and undercut, naturalistic and spiky. In Late Antique and Byzantine practice, the leaves may be blown sideways, as if by the wind of Faith. Unlike the Doric and Ionic column capitals, a Corinthian capital has no neck beneath it, just a ring-like astragal molding or a
Perovskite (structure) properties of interest to materials science among perovskites include superconductivity, magnetoresistance, ionic conductivity, and a multitude of dielectric properties, which are of great importance in microelectronics and telecommunication. Because of the flexibility of bond angles inherent in the perovskite structure there are many different types of distortions which can occur from the ideal structure. These include tilting of the octahedra, displacements of the cations out of the centers of their coordination polyhedra, and distortions of the octahedra driven by electronic factors (Jahn-Teller distortions). Synthetic perovskites have been identified as possible inexpensive base materials for high-efficiency commercial photovoltaics – they showed
