Corinthian order simply an example of a votive column. A few examples of Corinthian columns in Greece during the next century are all used "inside" temples. A more famous example, and the first documented use of the Corinthian order on the exterior of a structure, is the circular Choragic Monument of Lysicrates in Athens, erected c. 334 BC. A Corinthian capital carefully buried in antiquity in the foundations of the circular "tholos" at Epidaurus was recovered during modern archaeological campaigns. Its enigmatic presence and preservation have been explained as a sculptor's model for stonemasons to follow in erecting the temple dedicated to
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
