TL;DR: It is demonstrated that, in addition to high permittivity, CaCu3Ti4O12 has remarkably strong nonlinear current–voltage characteristics without the addition of any dopants.

TL;DR: The results show that a nanogenerator can be used to power flexible displays by means of mechanical agitations for future touchable display technologies.

TL;DR: Sintering and accompanying microstructural evolution is inarguably the most important step in the processing of ceramics and hard metals as mentioned in this paper, where an ensemble of particles is converted into a coherent object of controlled density and microstructure at an elevated temperature (but below the melting point) due to the thermodynamic tendency of the particle system to decrease its total surface and interfacial energy.

TL;DR: In this article, a TEM observation revealed that almost all the grain boundaries were faceted and the growth of BaTiO 3 grains was suppressed while growth of matrix grains was enhanced, showing normal grain growth behavior.

TL;DR: In this paper, a mixed A-site Pb-free solid solution series of (100−x)Na 0.5Bi0.5TiO3-xSrTiOO3 (0≤x≤40) was investigated by means of x-ray diffraction, dielectric, and Raman scattering techniques over a temperature range of 20 −550°C.
