Generalized Gradient Approximation Made Simple
TL;DR: A simple derivation of a simple GGA is presented, in which all parameters (other than those in LSD) are fundamental constants, and only general features of the detailed construction underlying the Perdew-Wang 1991 (PW91) GGA are invoked.

Lead-free piezoceramics
Yasuyoshi Saito,Hisaaki Takao,Toshihiko Tani,Tatsuhiko Nonoyama,Kazumasa Takatori,Takahiko Homma,Toshiatsu Nagaya,Masaya Nakamura +7 more
TL;DR: A lead-free piezoelectric ceramic with an electric-field-induced strain comparable to typical actuator-grade PZT is reported, achieved through the combination of the discovery of a morphotropic phase boundary in an alkaline niobate-based perovskite solid solution, and the development of a processing route leading to highly textured polycrystals.
