Ionic order that the Doric column had its initial basis in the proportions of the male body, while Ionic columns took on a "slenderness" inspired by the female body. Though he does not name his source for such a self-conscious and "literary" approach, it must be in traditions passed on from Hellenistic architects, such as Hermogenes of Priene, the architect of a famed temple of Artemis at Magnesia on the Meander in Lydia (now Turkey). Renaissance architectural theorists took his hints, to interpret the Ionic order as matronly in comparison to the Doric order, though not as wholly feminine as the Corinthian
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
