Greco-Roman world and Latin. "Greco-Roman" architecture is the architecture of the Roman world that followed the principles and style established in ancient Greece. The most representative building of that era was the temple. Other prominent structures that represented the style included government buildings, like the Roman Senate, and cultural structures, like the Colosseum. The three primary styles of column design used in temples in classical Greece were Doric, Ionic and Corinthian. Some examples of Doric architecture are the Parthenon and the Temple of Hephaestus in Athens, while the Erechtheum, which is located right next to the Parthenon is Ionic. The Romans made
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
