The efficiency of devices based on advanced ceramics is related to the optimization of material properties. In this paper, we discuss the intrinsic and extrinsic factors that influence the properties of advanced ceramics.

Phase transitions (symmetries) in ceramic and crystalline materials are widely explored in electrical-electronic devices.In this paper, we present the symmetries of the perovskite structure and the phase transitions due to temperature.

The Complex Impedance Spectroscopy (CIS) technique is used to characterize materials with electrical and ferroelectric properties. In this paper, we present the 4 formalisms for analyzing the data obtained by the CIS.

Apresentamos dois capítulos do livro "Princípios de Energia e Tempo" de André Bonaventura no qual discute a Teoria Quântica da Gravidade e a solução para Matéria Escura.
