Magnetoelectric (ME) laminated composites with strong ME coupling are becoming increasingly prevalent in the electron device field. In this paper, an enhancement of effect via transition-layer implantation for co-fired lead-free composite (80Bi0.5Na0.5TiO3-20Bi0.5K0.5TiO3)/(Ni0.8Zn0.2)Fe2O4 (BNKT/NZFO) was demonstrated. A transition layer composed particulate 0.5BNKT-0.5NZFO introduced between ...

Metal oxide anode materials are affected by severe volume expansion and cracking in the charging/discharging process, resulting low capacity poor cycle stability, which limits their application lithium-ion batteries (LIBs). Herein, a new strategy is uncovered for preparing spinel-structured, multi-component transition metal oxide, (Ni,Co,Mn)Fe2O4−x, with oxygen vacancies as an LIB material. The...

High-entropy metal spinel oxide (HEO) is proved to be a promising oxygen evolution reaction (OER) catalyst with high catalytic performance and stability. A short routine synthesis process based on solution combustion was proposed prepare (Co0.25Ni0.25Mn0.25Zn0.25)Fe2O4 HEO in this work. During the process, products were rapidly synthesized melted due high-temperature reaction, then quickly crys...

The heat transmission in a non-Newtonian hybrid nanofluid that combines particles of graphene oxide (GO) and iron dioxide (Fe2O4) with the base fluid chosen as ethylene glycol (EG) is analyzed, including effects radiation magnetic influence. flow assumed to be asymmetric because it flows along horizontal shrinking surface response external inducements. mathematically modelled partial differenti...

The exploration of new catalytic hosts is highly important to tackle the sluggish electrochemical kinetics sulfur redox for achieving high energy density lithium–sulfur batteries. Herein, first time, we present high-entropy oxide (HEO, (Mg0.2Mn0.2Ni0.2Co0.2Zn0.2)Fe2O4) nanofibers as host sulfur. HEO show a synergistic effect among multiple metal cations in spinel structure that enables strong c...
