Summary: Biochar is a carbon-rich solid derived from biomass through thermal treatment in an oxygen-limited environment. Its structural and electrochemical properties can be optimized through customization techniques like increasing porosity, enlarging surface area, enhancing graphitization, and modifying surface functionalities with heteroatoms. This review mainly focuses on the preparation strategies of biochar-based materials for energy and hydrogen storage, as well as the tuning and optimization of their structural properties for specific applications. The hierarchical porous structure with heteroatom surface functionalities is desirable for supercapacitor application, while the graphitic structure and interlayer spacing are critical for battery applications. High surface area, micropore-dominant structure, and oxygen-rich functional groups are required for H2 storage in biochar.

Summary: Polyoxometalates (POMs) clusters have attracted significant attention in electrochemical and energy storage fields due to their abundant redox activity, tunability, and specific atomic structure. However, their high solubility and fully oxidized state often result in electrical insulation and chemical instability. To overcome these challenges, researchers have explored non-covalent loading and covalent grafting of POMs on conductive substrates, but these methods have limitations in terms of stability and availability. Precise confinement of POMs into conductive supports has emerged as a promising approach to improve dispersibility and stability.

The study focuses on the interaction between the microstructure and electrochemical performance of the products obtained at different calcination temperatures. The results show that the porous Fe-Fe0.33Mn0.67O/C nanocubes exhibit the best rate capability and cycle life, attributed to the shorter Li+ diffusion path provided by the porous structure and the buffering effect of N-doped C on volume change and aggregation of Fe0.33Mn0.67O nanoparticles.

Summary: MOF-based composites have gained widespread attention for their controllable morphology and pore characteristics. However, the poor conductivity and volume expansion limit their practical application in LIBs. In this study, a quasi-Cu-MOF composite was fabricated using HKUST-1 as the precursor through a simple thermal decomposition strategy. The results showed that the quasi-Cu-MOF composite exhibited superior reversible specific capacity (627.5 mAh/g at 100 mA/g) and outstanding cycle stability (514.6 mAh/g at 500 mA/g after 400 cycles) as anodes for LIBs. The study demonstrated that the low-temperature calcination strategy played a significant role in preserving the morphology during cycling and the derived copper framework was crucial for improving conductivity. This work provides guidance for the design of high-performance electrodes with advanced three-dimensional hierarchical structures.

Summary: Hierarchical NiO nanosheets@nanorods have been designed and constructed for efficient urea electrooxidation in alkaline solution. The integration of Ni(OH)2 nanosheets and NiC2O4 nanorods in a heterostructure through one-step anion-competitive reaction strategy results in the hierarchically porous structure and high specific surface area. These NiO nanosheets@nanorods exhibit superior activity with a low overpotential, slight Tafel slope, and high stability in urea electrooxidation. This work promotes the application of well-designed hierarchical structure in electrooxidizing urea.

Summary: This study successfully prepared SiC ceramic composites with complex shapes and high flexural strength by combining digital light processing (DLP) and reactive solution infiltration process (RMI). A low-absorbance SiO2 cladding layer was formed on the surface of SiC powder, and a photosensitive ceramic slurry with improved curing properties was formulated. Ceramic green bodies were molded using DLP, and then sintered and densified to obtain SiC ceramic composites with desired properties. This approach can effectively reduce the manufacturing cycle and cost of SiC ceramic composites.

Summary: Precast hollow shear wall structure is a new type of prefabricated shear wall structure, consisting of precast hollow panels, cast-in-place boundary elements, and cast-in-place vertical splice joints. Quasi-static tests on hollow shear wall specimens were conducted to study their seismic performance. The experimental results showed that the specimens failed due to flexure-compression and the horizontal reinforcement indirectly connected by horizontal inserts effectively resisted horizontal shear force. The seismic performance of the hollow shear wall with precast boundary elements met the requirements.

Summary: Silicon carbide is a crucial high-performance engineering ceramic, but shaping, sintering, and processing SiC ceramics with complex structure and high mechanical performance are challenging. Additive manufacturing has the potential to solve these issues, however, low solid content in the photosensitive slurry leads to high residual Si content and low strength of final components. In this study, a novel strategy was developed to prepare high-strength SiC components with complex structure by using vat photopolymerization 3D printing technology and reactive melt infiltration process. The resulting RB-SiC ceramics exhibited outstanding flexural strength and elastic modulus, making it a promising method for manufacturing structural SiC ceramics.

Summary: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
