1. Unified comprehension of the kinetics of isothermal ceramic processes under field-free and resonant wave-field conditions
Abstract This paper proposes a unified comprehension of the isothermal ceramic process kinetics stemming from mesoscopic irreversible thermodynamics. Accordingly, a unified process kinetic equation (UPKE) is derived, which predicts that the global isothermal process rate of any ceramic process is, in general, nonlinearly related both to its activation energy

2. Densificação e condutividade elétrica da Zircônia-Escândia-Céria / Densification and electrical conductivity of Zirconia-Scandia-Ceria
Estudos recentes demonstram que o sistema cerâmico zircônia-escândia-céria (ScCeSZ) apresenta-se promissor para aplicações como eletrólito sólido em células a combustível de óxido sólido de temperaturas intermediárias de operação (600 a 800 °C). Neste trabalho, foi realizada a sinterização convencional, de duas etapas e assistida por campo

3. Ferritas de cobre e zinco do tipo espinélio sintetizadas pelos métodos: hidrotermal assistido por micro-ondas, precursores poliméricos, reação no estado sólido e decomposição térmica / Spinel type copper and zinc ferrites synthesized by the methods: microwave assisted hydrothermal, polymeric precursor, solid state reaction and thermal decomposition.
Ferrites are well studied materials due to their wide application as: gas detector, optical, electronic and magnetic devices, catalyst and pigments. In the synthesis of materials, the properties are extremely influenced by the synthesis method. In this work, four methods were used in the synthesis of spinel ferrites with composition Zn1-xCuxFe2O4 (x = 0,0; 0
