Integrating the battery behavior and supercapacitor in a single electrode to obtain better electrochemical performance has been widely researched. However, there is still lack of research studies on an integrated battery–capacitor (BatCap electrode). In this work, BatCap porous carbon-coated Mn–Ni-layered double oxide (Mn–Ni LDO-C) was fabricated successfully using controllable heat treatment polypyrrole-precoated hydroxide LDH@PPy). This Mn–Ni LDO-C grown Ni foam directly possessed...
In this article, the temperature-dependent complex Hall effect near magnetization compensation temperature of CoGd alloy films is systematically studied. We find anomalies loops with characteristics similar to topological (THE), which usually considered indicate occurrence spin texture. However, THE ruled out by detailed magnetic and transport measurements on different composition ratios. After considering influence spin-flop inhomogeneity components naturally formed in ferrimagnetic alloy,...
Fiber supercapacitors have attracted significant attention owing to the relevancy in textile electronics. However, key challenge is achieve a high output voltage and performance fiber supercapacitors, while maintaining flexibility as fibers. Here, we present particular type of based on an overlaid tree topological configuration, by braiding sub-fiber supercapacitor units asymmetrical series connection. The tree-like topology-based asymmetric (TTAFSCs) simultaneously achieved energy density...
Fiber supercapacitors have attracted significant attention because of the relevance for textile electronics. However, key challenge is to achieve high output voltage and performance fiber while maintaining flexibility fibers. Here, we present a supercapacitor, based on an overlaid tree topology configuration, by braiding sub-fiber supercapacitor units in asymmetrical series connection. The tree-like topology-based asymmetric (TTAFSCs) energy density (0.022 Wh cm−3 at power 0.444 W cm−3) with...
The gyromagnetic ratio γ is a key quantity that determines spin and magnetic properties. In this study, investigated via the electric detection of ferromagnetic resonance first-principles calculations for c-axis oriented hcp-Co1−xIrx () soft films with easy-plane magnetocrystalline anisotropy. increases linearly from 19.13 GHz kOe−1 pure Co film to 19.32 at x= 0.23, which in agreement calculated result. reveal primary reason variation different trends orbital moments neighboring atoms Ir,...
Summary Structural steels are widely used in engineering fields. Generally, they have the advantage of lower prices due to less precious alloy elements contained; however, their properties, especially surface properties inferior high steels. Surface importance improving steels, and even a ’new’ layer with performances can be produced by technologies on low cost structural ordinary properties. The researches last decade shown that nanocrystallization (SNC) markedly improve mechanical metallic...
