A simple flash sintering setup under applied mechanical stress and controlled atmosphere
UNLABELLED Most flash sintering experimental set-ups use dog bone-shaped specimen and DC current, which results in heterogeneously distributed densification and grain growth throughout the sample. This is the reason why only the sample's core characteristics after flash are taken into account. On the other hand, some recent procedures suggest the use of cylindrical pellets, which have some adva...
متن کاملSintering in Nitrogen Atmosphere of Iron-Rich Glass-Ceramics
The sintering and the crystallization of two iron-rich glass compositions (45–75m powder fractions) were studied in air and nitrogen atmospheres. The phase formation was evaluated by differential thermal analysis, while the densification, by dilatometry; the crystalline phases were identified by X-ray diffraction and the structure observed by scanning electron microscopy. It was highlighted tha...
متن کاملOrder-Disorder Behavior in KNbO3 and KNbO3/KTaO3 Solid Solutions and Superlattices by Molecular-Dynamics Simulations
We use molecular-dynamics simulation to examine the order-disorder behavior in pure ferroelectric KNbO3 and in KNbO3-KTaO3 ferroelectric-paraelectric solid solutions and superlattices. We find that the order-disorder behavior is remarkably robust and plays an important role in both the polarization rotation associated with switching of the perfect crystal and in the dynamical behavior of the so...
متن کاملControlled atmosphere, modified atmosphere and modified atmosphere pack- aging for vegetables
Purpose of Review: This review is aimed at illustrating the directions in which research on controlled atmosphere (CA), modified atmosphere (MA) and modified atmosphere packaging (MAP) for fresh and fresh-cut vegetables has been focused since about 2000, and to highlight significant new findings in the field. Findings: In the last 5 years, little research with vegetables has been carried out to...
متن کاملBlue-light-induced infrared absorption in KNbO3
Owing to its high nonlinearity and low passive losses, KNbO3 has great potential as a medium for efficient frequency doubling and parametric oscillation." 2 For example, KNbO3 has been used successfully for the production of cw blue light by frequency doubling of a dye laser,3 doubling of a semiconductor diode laser,4 and nonlinear mixing of diode and Nd:YAG lasers.5 In recent work we observed ...
