Self-healing effect based on electrolyte/dielectric co-existence characteristic of sol-gel-derived aluminum oxide thin film
Ya Wang, Zhen Su, Jianwen Chen, Zaifang Li, Manwen Yao, and Xi Yao
Dielectric capacitors are receiving increasing attention due to the high-power density and fast charge–discharge speed. However, defects are inevitably induced during the preparation process and then weaken the breakdown strength, thereby limiting their energy density.

However, defects are inevitably induced during the preparation process and then weaken the breakdown strength, thereby limiting their energy density. The phenomenon gives rise to self-healing technology. The discovery of sol–gel-derived aluminum oxide with electrolysis and dielectric dual-characteristic provides a novel, simple and cost-effective self-healing method to heal defects and enhance energy density. In this paper, we systematically reviewed the current self-healing technologies and the important progress of electrolysis and dielectric co-existence dielectrics. Finally, we outlook the electrolysis and dielectric co-existence dielectrics and potential challenge..

CaCu3Ti4O12 (CCTO) is a potential dielectric material with giant permittivity, good stability over the wide temperature and frequency range. However, the dielectric responses of CCTO-based ceramics are mainly investigated in the frequency of 10 2–106 Hz, which is far low to clarify the intrinsic dielectric feature. So,CaCu3Ti4

Establishment of magneto-dielectric effect and magneto-resistance in composite of PLT and Ba-based U-type hexaferrite
Kanika Aggarwal, Madan Sharma, Shubhpreet Kaur, Vishal Arora, Indu Sharma, Rakesh Kumar, and Anupinder Singh
We are examining the behavior of a composite made of ferroelectrics with strong dielectric properties and ferrites with magnetic properties due to the rising need for materials for multipurpose devices. Many application avenues will be favored by the pairing of these materials’ individual qualities with one another.

High entropy oxides (HEO) are single-phase solid solutions which are formed by the incorporation of five or more elements into a cationic sublattice in equal or near-equal atomic proportions. Its unique structural features and the possibility of targeted access to certain functions have attracted great interest from reHigh entropy oxides (HEO) are single-phase solid solutions which are formed by the incorporation of five or more elements into a cationic sublattice in equal or near-equal atomic proportions. Its unique structural features and the possibility of targeted access to certain functions have attracted great interest from researchers. In this review, we summarize the recent advances in the electronic field of high-entropy oxides. We emphasize the following three fundamental aspects of high-entropy oxides: (1) The conductivity mechanism of metal oxides; (2) the factors affecting the formation of single-phase oxides; and (3) the electrical properties and applications of high-entropy oxides. The purpose of this review is to provide new directions for designing and tailoring the functional properties of relevant electronic materials via a comprehensive overview of the literature on the field of high-entropy oxide electrical properties..

Photocatalytic water splitting kinetics of CMV model
J. H. Hu, and C. L. Wang
The photocatalytic water splitting kinetics has been analyzed in this paper. The experimental data are taken from the published works and fitted with different theoretical models. From the results, we find that the photocatalytic kinetics of water splitting can be described by Capelas-Mainardi–Vaz (CMV) model very wellThe photocatalytic water splitting kinetics has been analyzed in this paper. The experimental data are taken from the published works and fitted with different theoretical models. From the results, we find that the photocatalytic kinetics of water splitting can be described by Capelas-Mainardi–Vaz (CMV) model very well. This suggests that the water splitting kinetics can be regarded as a fractional first-order kinetics of the chemical reaction. Also, we notice that photocatalytic water splitting is not always completely a monotone kinetics process..
