ABSTRACT Given their high safety, environmental friendliness and low cost, aqueous zinc-ion batteries (AZIBs) have the potential for high-performance energy storage. However, issues with structural stability electrochemical kinetics during discharge/charge limit development of AZIBs. In this study, vanadium oxide electrodes organic molecular intercalation were designed based on intercalating 11 kinds charged carboxylic acid ligands between 2D layers to regulate interlayer spacing. The...
Abstract MXenes, have been considered as a new generation anode material in lithium‐ion batteries for lower diffusion barriers and superior conductivity. Unfortunately, their structures are prone to aggregation stacking, hindering further shuttle of lithium ions electrons, resulting discharge capacity. Therefore, the introduction interlayer spacers preparation MXene‐based hybrids has attracted much attention. Introducing Prubssian blue analogues (PBAs) spacer combine with MXene nanosheets...
In this letter, electromagnetic band-gap (EBG) structure is used to reduce the radar cross section (RCS) of patch array antenna. The proposition method based on high impedance characteristic mushroom-like EBG structure. basic antenna designed with a central frequency 5.0 GHz while replacing substrate band in which RCS reduced significantly can be adjusted by parameters EBG. backward as much 10 dB compared that conventional antenna, and degradation performance not significant.
Abstract 2D metal carbides/nitrides (MXenes) have attracted considerable interest in NH 3 sensing due to their high electrical conductivity and abundant terminal groups. However, the strong interlayer interactions between MXene nanosheets result challenges related recovery rapid response decay MXene‐based sensors. Here, a one‐step hydrothermal strategy is developed that anchors Zn atoms grows ZnO polycrystals on Ti vacancies of C 2 T x layers, forming sandwich‐structured ZnO/Ti...
Plum fruit and kernels offer bioactive material for industrial production. The promising procedure distinguishing plum kernel cultivars used in this study comprised two stages: image analysis to compute the texture parameters of belonging three ‘Emper’, ‘Kalipso’, ‘Polinka’, discriminant using machine learning algorithms classify based on selected textures with highest discriminative power. models built separately sets from all color channels L, a, b, R, G, B, U, V, S, X, Y, Z, space Lab...
The syntheses and catalytic application of two-dimensional (2D) metallic nanomaterials have attracted much attention due to their extraordinary physical, electronic, chemical, optical properties. Herein, well-defined large-size ultrathin Rh nanosheets with a thickness approximately 0.72 nm were successfully prepared by using one step solvothermal method at 180 °C for 4 h Rh(acac)3 as precursor, water solvent, EDTA·2Na stabilizer, HCHO both reducing agent shape-controlling agent. formation...
Layered vanadium-based compounds have attracted attention as cathode materials for aqueous zinc-ion batteries (AZIBs) because of their low cost, high theoretical specific capacity, and abundant vanadium valence states. However, the slow migration Zn2+ ions poor cycling stability hinder practical application in AZIBs. Herein, using a one pot solvothermal method, polyoxometalates (POMs) were inserted into aluminum vanadate interlayer spacing, series novel three-dimensional nanoflower...

Nowcasting is a critical technology for disaster prevention and mitigation, the accuracy of radar echo extrapolation directly impacts forecasting performance. In most deep learning-based models, accurately predicting heavy precipitation remains challenging task. Focusing on region China, this study proposes an improved model based residual attention mechanisms—RA-UNet—for nowcasting with lead time 3 h. The introduces neural network (ResNet) convolutional block module (CBAM) to integrate...
Low birth weight (LBW) is an important risk factor for neonatal and infant mortality morbidity in adults.. How-ever, no large scale study on the prevalence of LBW related maternal factors China has been published. To explore effects term China, we conducted a hospital-based retrospective 55, 633 Chinese pregnancy cases between 2001 2008. Maternal sociodemographic data, history infer-tility contraceptive use were obtained. Their medical status diseases during pre-pregnancy examined by...
Long-life pavement construction is an important research direction for sustainable road development. Fatigue cracking of aging asphalt one the main reasons that affects its service life, and improving fatigue resistance has become a key factor in promoting development long-life pavement.
