Layered double hydroxide (LDH) materials, especially metal–organic framework (MOF)-derived LDHs, have attracted much attention in electrochemical capacitor applications. However, the construction of porous three-dimensional microsphere architectures with controlled morphology is highly demanded for high-performance supercapacitor electrodes. Thus, a simple and effective strategy recommended to design fabricate well-defined layered structure LDHs high performance. In this study, we...
Graphene-ZnO nanocomposites (G-ZnO) were prepared by a facile solvothermal approach. Well, crystalline ZnO nanoparticles with size in the range of 30–70 nm are uniformly deposited on graphene sheets, as evidenced different techniques. The electrochemical properties examined measuring specific capacitance 6 M KOH solution using cyclic voltammetry and galvanostatic charge–discharge G-ZnO showed good capacitive behavior 122.4 F/g compared to oxide (2.13 F/g) rGO (102.5 at 5 mV/s scan rate....
Single- or few-layered h-BN nanosheets (BNNSs) are analogous to graphene and possess unique properties. However, their technological applications were severely hindered by the low production efficiency of BNNSs. We reported here a study in which BNNSs efficiently produced exfoliating bulk powder thionyl chloride without using any dispersion agents. The yield was as high 20%, it could be doubled through second round exfoliation precipitate. Microscopic results revealed that generally...

Abstract Flexible transparent electrodes (FTEs) with embedded metal meshes play an indispensable role in many optoelectronic devices due to their excellent mechanical stability and environmental adaptability. However, low‐cost, simple, efficient, friendly integrated manufacturing of high‐performance remains a huge challenge. Here, facile novel fabrication method is proposed for FTEs mesh via liquid substrateelectric‐field‐driven microscale 3D printing process. This direct strategy avoids...
We all depend on mobility, and vehicular transportation affects the daily lives of most us. Thus, ability to forecast state traffic in a road network is an important functionality challenging task. Traffic data often obtained from sensors deployed network. Recent proposals spatial-temporal graph neural networks have achieved great progress at modeling complex correlations data, by as diffusion process. However, intuitively, encompasses two different kinds hidden time series signals, namely...
Multivariate Time Series (MTS) forecasting plays a vital role in wide range of applications. Recently, Spatial-Temporal Graph Neural Networks (STGNNs) have become increasingly popular MTS methods. STGNNs jointly model the spatial and temporal patterns through graph neural networks sequential models, significantly improving prediction accuracy. But limited by complexity, most only consider short-term historical data, such as data over past one hour. However, time series dependencies between...

Quantum-dot light-emitting diodes (QLEDs) with high brightness have potential application in lighting and display. The is realized at current density (J). However, J, the efficiency drops significantly, thereby limiting achievable brightness. This notorious phenomenon has been known as roll-off, which likely caused by Auger- and/or thermal-induced emission quenching.
