TL;DR: In this paper, a review of existing capacitor technologies and the potential new capacitor technologies toward realizing these goals is presented, and various dielectric materials beneficial to high dielectrics constant and breakdown strength potentially meeting the high requirements are discussed.
Abstract: The demand for smaller and lighter capacitors with higher temperature capability is increasing in the power electronic industry and military arena. This article reviews existing capacitor technologies and the potential new capacitor technologies toward realizing these goals. Various dielectric materials beneficial to high dielectric constant and breakdown strength potentially meeting the high requirements are discussed. The importance of dielectric composites including selection of nanofillers and matrix is discussed. The successful implementation of these dielectric materials for high energy density purpose requires a detailed understanding of both materials engineering and processing.
TL;DR: In this article, the authors reviewed the recent findings on seismo electromagnetic phenomena, including ULF emissions, seismo-atmospheric and -ionospheric perturebations, Earth's surface temperature anomaly, in-situ observational results etc.
Abstract: Electromagnetic phenomena are recently found to take place prior to an earhquake, and they are regarded as the most promising candidate for short-term earthquake prediction. This report reviews the recent findings on seismo electromagnetic phenomena, including ULF emissions, seismo-atmospheric and -ionospheric perturebations, Earth's surface temperature anomaly, in-situ observational results etc.
TL;DR: In this paper, the authors measured the space charge distribution using a pulsed electro-acoustic (PEA) system under high DC electric field of more than 100 kV/mm in a nano-composite film of the low density polyethylene (LDPE) mixed with a nano size filler of MgO.
Abstract: Space charge characteristics under high DC electric field of more than 100 kV/mm in a nano-composite film of the low density polyethylene (LDPE) mixed with a nano-size filler of MgO were studied using a pulsed electro-acoustic (PEA) method. To measure the space charge distribution using the PEA system under the high electric field in a thin film, a spatial resolution of the PEA system was improved. Using the improved system, the time dependence of space charge formation in LDPE and LDPE/MgO nano-composite under the high electric field was observed. It is found that a huge amount of packet-like charge generation in LDPE makes a local electric field in the bulk higher. On the other hand, there is almost no such huge packet-like charge observed in LDPE/MgO with MgO content of more than 0.5 phr, while it was observed in that of 0.2 phr. It is found that the generation of the packet-like charge under the high electric field strongly depends on the content of MgO in the LDPE/MgO nano-composite.
