Summary: This study introduces the reaction between nano-ZnO and H2C2O4 in the electrospinning solution to effectively adjust the heterostructure of TiO2/ZnO and control the particle size of nano-spheres. The soaking and calcination process allows ZnO to fully combine with the TiO2 precursor, forming a phase-mixed heterojunction. The phase-mixed structure enhances light utilization and results in enhanced photocatalytic activity and cycling stability of TiO2/ZnO mixed materials. This research provides a new approach for the preparation of controllable metal oxide phase-mixed materials.

Summary: Spatial keyword query has attracted attention due to existing indexes' low efficiency in skewed data. This paper proposes ARM-SQ, a novel spatial keyword index based on association rule mining. It avoids intersection of long lists by materializing inverted lists with frequent item sets mined by association rules. A depth-based materialization strategy is introduced to balance query and space costs, and a benefit-based greedy frequent item set selection algorithm, BGF-Selection, is implemented for query execution. Experimental results show that BGF-Selection outperforms existing algorithms with significantly higher efficiency than SFC-Quad.

Summary: This study found that adding pyrochar (PC) and hydrochar (HC) to calcareous soils has positive effects on nutrient uptake by maize seedlings and reveals the important role of mycorrhizal colonization. The effects depend on the type of biochar added and the type of nutrient evaluated. Maize seedlings in the HC and PC groups had higher dry weights and 17% higher phosphorus accumulation compared to the control group. Adding PC significantly increased zinc accumulation and copper concentration and accumulation in maize seedlings, while adding HC increased iron concentration. Applying PC and HC also promoted mycorrhizal colonization of maize roots, and phosphorus, zinc, and copper accumulations in the plant were positively correlated with the mycorrhizal colonization rate.

Summary: Returning straw-like agricultural waste to the field through hydrothermal carbonization (HTC) is important for waste utilization, soil improvement, and carbon sequestration. This study proposes strategies to optimize the liquid-solid ratio (LSR) of HTC and evaluates the stability, soil application potential, and economic benefits of corn stover-based hydrochar under different LSRs. The results show that reducing LSR increases the dissolved organic carbon content, but does not significantly affect other properties of the hydrochar. The optimized LSR enhances soil application potential and economic benefits.

Summary: The interaction between vascular endothelial cells (VECs) and nanomaterials is crucial for the safe and efficient application of nanomedicine. Researchers have discovered that two-dimensional PEGylated lamellar materials (PLMs) can significantly stimulate VECs by interacting with membrane lipids and inducing changes in calcium ion channels. In vivo studies have shown that PLMs-stimulated VECs have diverse impacts on atherosclerosis and tumor-associated nanomedicine accumulation. This study not only enhances our understanding of the mechanism by which specific proteins on VEC membranes are stimulated by PLMs but also provides guidance for the rational use of promising PLMs in nanomedicine.

Summary: Porous carbon systems doped with heteroatoms have potential for high energy density and power density. However, there is a lack of understanding of the relationship between heteroatom types and electrochemical properties, resulting in trial-and-error approaches for supercapacitor development. In this study, we synthesized biomass-derived carbon systems doped with N, S, and O atoms, which exhibited large specific surface areas and hierarchical porous structures. Our analysis of experimental evidence and theoretical simulations established doping principles for predictive electrochemical performance. The doped materials had broad operating voltage range (up to 1.8 V) in aqueous electrolytes and improved capacitive ions adsorption. They also demonstrated high energy density (25.2 Wh kg-1 at 180 W kg-1) and excellent cycling performance (97.6% capacity retention after 20,000 cycles). This work provides insights for designing advanced heteroatom-doped carbon electrodes.

Summary: Current vaccine delivery systems aim to replicate the natural dissemination of live pathogens, but fail to consider that pathogens evolve to evade the immune system. A new multi-layered aluminum hydroxide-stabilized emulsion (MASE) has been developed to dictate the delivery sequence of antigens, resulting in enhanced immune responses and decreased viral loads in H1N1 influenza and SARS-CoV-2 vaccines. By reversing the delivery sequence of surface antigen and core antigen, the inside-out strategy may offer major implications for enhanced vaccinations against enveloped RNA viruses.
