Summary: In this study, a method of synergistic enhancement of oxidation was reported by simultaneously harvesting solar and mechanical vibrations through flexible piezo and photocatalytic composite nanofiber mats. By incorporating photocatalytic TiO2 in flexible piezoelectric PAN nanofiber support, the piezoelectric fields generated under the mechanical deformation promote the separation of the photogenerated electrons and holes to accelerate oxidation of pollutants. The experimental results demonstrated that the catalytic activity of PAN/TiO2 nanofibers can be greatly enhanced by environmental vibration-induced piezoelectricity, with a maximum enhancement factor of about 2.5.

Summary: Porphyrins have been widely used as photosensitizers in the field of photovoltaics and photocatalysis due to their ability to transfer energy from light-collecting areas to reaction centers, similar to natural photosynthesis. However, while solar cell development has led to continuous improvement in the molecular design of these pigments, these innovations have not been efficiently applied to dye-sensitized photocatalysis. This review aims to explore recent advances in the role of porphyrin structural motifs as sensitizers in TiO2-mediated catalysis, providing valuable insights for the development of more efficient photocatalysts.

Summary: The study established the influence of the crystalline phase and agglomeration degree of TiO2 nanoparticles on photocatalytic hydroxyl radical formation and bacterial inactivation in TiO2/SiO2 composite coatings. A relationship between hydroxyl radicals' formation and charge carrier transfer mechanism between defect levels in SiO2 and TiO2 embedded nanoparticles was established through a simple spectroscopic method. This correlation complements the lack of mechanisms behind the photocatalytic activity in TiO2/SiO2 composites.

Summary: Tubular Au/TiO2/SiO2 ternary nanocomposite with high-temperature ablation and noble metal deposition was successfully fabricated. SiO2 deposition inhibits the growth of TiO2 grain size, and the tubular structure effectively improves the utilization of visible-light. Au nanoparticles absorb visible-light, promote the formation of photogeneration-hole pairs, and act as an electron acceptor to delay the recombination rate of photogeneration electron-hole pairs, thereby improving the photocatalytic activity. Moreover, the composite gel of polyvinyl alcohol/polyvinylpyrrolidone (PVA/PVP) used for loading and immobilizing TiO2-based catalytic materials exhibits good photocatalytic activity and recyclability.

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.

In this research, a strategy using biomass-derived hierarchical porous carbon as supports was proposed to achieve high capacitance and rapid ion/charge transport. The deposition of nanosized MnO2 and MnO on the carbon support was achieved through a slow redox reaction. The excellent performance, low cost, and environmental friendliness highlight the great promise of biomass waste in designing carbon supports for electrochemical applications.

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.
