Induced Giant Piezoelectricity in Centrosymmetric Oxides

Autor: Park, D. -S., Hadad, M., Rimer, L. M., Ignatans, R., Spirito, D., Esposito, V., Tileli, V., Gauquelin, N., Chezganov, D., Verbeeck, D. Jannis J., Gorfman, S., Pryds, N., Muralt, P., Damjanovic, D.

Piezoelectrics are materials that linearly deform in response to an applied electric field. As a fundamental prerequisite, piezoelectric material must possess a non centrosymmetric crystal structure. For more than a century, this remains the major ob

Some topological considerations on semistar operations

Autor: Finocchiaro, C. A., Spirito, D.

We consider properties and applications of a new topology, called the Zariski topology, on the space ${\rm SStar}(A)$ of all the semistar operations on an integral domain $A$. We prove that the set of all overrings of $A$, endowed with the classical
