Narrow Results

High performance dielectric capacitors are ubiquitous components in the modern electronics industry, owing to the highest power density, fastest charge–discharge rates, and long lifetime. However, the wide application of dielectric capacitors is limited owing to the low energy density. Over the past decades, multiscale structures of dielectric ceramics have been extensively explored and many exciting developments have been achieved. Despite the rapid development of energy storage properties, the atomic structure of dielectric materials is rarely investigated. In this paper, we present a brief overview of how scanning transmission electron microscopy (STEM) is used as a tool to elucidate the morphology, local structure heterogeneity, atomic resolution structure phase evolution and the correlation with energy storage properties, which provides a powerful tool for rational design and synergistic optimization.

This report presents preliminary results from a survey commissioned for ICME-14 on teaching and learning of mathematical modelling and interdisciplinary mathematics educations. The systematic literature review focusses on how a well-understood relation between mathematics and the real world underpins interdisciplinary work, interdisciplinarity in research and teaching teams, issues and challenges in the relationships among mathematical modelling, mathematics, the real world and interdisciplinarity, and mathematical modelling and a well-understood relation to the real world ensuring mathematical depth in STEM integration.
