Decoupled charge and heat transport in Fe2VAl composite thermoelectrics with topological-insulating grain boundary networks Decoupling charge and heat transport is essential for optimizing thermoelectric materials. Strategies to inhibit lattice-driven heat transport, however, also compromise carrier mobility, limiting the performance of most thermoelectrics, including Fe<sub>2</sub>VAl Heusler compounds. Here, we demonstrate an innovative approach, which bypasses this tradeoff: via liquid-phase sintering, we incorporate the archetypal topological insulator Bi<sub>1-x</sub>Sb<sub>x</sub> between Fe<sub>2</sub>V<sub>0.95</sub>Ta<sub>0.1</sub>Al<sub>0.95</sub> grains. Structural investigations alongside extensive thermoelectric and magneto-transport measurements reveal distinct modifications in the microstructure, a reduced lattice thermal conductivity and a simultaneously enhanced carrier mobility arising from topologically protected charge transport along the grain boundaries. This yields a huge performance boost, resulting in one of the highest figure of merits among both half- and full-Heusler compounds, z ≈ 1.6 × 10<sup>-3</sup> K<sup>-1</sup> (zT ≈ 0.5) at 295 K. Our findings highlight the potential of topological-insulating secondary phases to decouple charge and heat transport and call for more advanced theoretical studies of multiphase composites.

Hydrogel-Based Systems as Smart Food Packaging: A Review In recent years, non-degradable petroleum-based polymer packaging has generated serious disposal, pollution, and ecological issues. The application of biodegradable food packaging for common purposes could overcome these problems. Bio-based hydrogel films are interesting materials as potential alternatives to non-biodegradable commercial food packaging due to biodegradability, biocompatibility, ease of processability, low cost of production, and the absorption ability of food exudates. The rising need to provide additional functionality for food packaging has led scientists to design approaches extending the shelf life of food products by incorporating antimicrobial and antioxidant agents and sensing the accurate moment of food spoilage. In this review, we thoroughly discuss recent hydrogel-based film applications such as active, intelligent packaging, as well as a combination of these approaches. We highlight their potential as food packaging but also indicate the drawbacks, especially poor barrier and mechanical properties, that need to be improved in the future. We emphasize discussions on the mechanical properties of currently studied hydrogels and compare them with current commercial food packaging. Finally, the future directions of these types of approaches are described.

A unimolecule nanopesticide delivery system applied in field scale for enhanced pest control Nanopesticides provide immense potential in reducing pesticide use and promoting sustainable agriculture for their enhanced pesticidal efficacy. Nano-enabled delivery systems can enhance pesticide penetration into both insects and leaves through their unique nanoproperties, in particular their small size. However, it remains a great challenge to achieve unimolecular formulations in water-based processes in order to take full advantages of nanoproperties. Here, using ionic liquid, we fabricate unimolecular nanopesticides (about 3 nm in average diameter) in a water-based process, termed unimolecule-nanopesticide delivery system. Guided by the density functional theory calculations, we successfully convert various traditional pesticides into the unimolecule-nanopesticide system, significantly enhancing cellular uptake, insect-dermis translocation, and leaf-cuticle penetration of pesticides. Furthermore, we improved field efficacy against multiple pests using the unimolecule-nanopesticide system. Importantly, the unimolecule-nanopesticide system utilizes only industry-grade raw materials that are Generally Recognized as Safe by the US Food and Drug Administration. We believe our unimolecule-nanopesticide system represents a water-based and facile-manufactured platform for other conventional pesticides to achieve high-efficiency field-scale plant protection.

Enhancing surface activity and durability in triple conducting electrode for protonic ceramic electrochemical cells With the material system operating at lower temperatures, protonic ceramic electrochemical cells (PCECs) can offer high energy efficiency and reliable performance for both power generation and hydrogen production, making them a promising technology for reversible energy cycling. However, PCEC faces technical challenges, particularly regarding electrode activity and durability under high current density operations. To address these challenges, we introduce a nano-architecture oxygen electrode characterized by high porosity and triple conductivity, designed to enhance catalytic activity and interfacial stability through a self-assembly approach, while maintaining scalability. Electrochemical cells incorporating this advanced electrode demonstrate robust performance, achieving a peak power density of 1.50 W cm⁻<sup>2</sup> at 600 °C in fuel cell mode and a current density of 5.04 A cm<sup>-2</sup> at 1.60 V in electrolysis mode, with enhanced stability on transient operations and thermal cycles. The underlying mechanisms are closely related to the improved surface activity and mass transfer due to the dual features of the electrode structure. Additionally, the enhanced interfacial bonding between the oxygen electrode and electrolyte contributes to increased durability and thermomechanical integrity. This study underscores the critical importance of optimizing electrode microstructure to achieve a balance between surface activity and durability.

Resveratrol-derived carbon dots integrated into gelatin/chitosan multifunctional films for intelligent packaging In this study, multifunctional Resveratrol-derived carbon dots (Res-CDs) were prepared using a hydrothermal method. Res-CDs exhibited good free-radical scavenging activities, attributed to abundant surface hydroxyl groups, and effectively inhibited <i>Staphylococcus aureus</i> and <i>Escherichia coli</i> growth at a concentration of 2 mg/mL. Composite films were prepared by combining Res-CDs with gelatin/chitosan. As well as excellent mechanical properties, the prepared films exhibited smooth surfaces, thermal stability, and good antioxidant, ultraviolet-shielding, antibacterial, and pH-responsive properties. Furthermore, cell viability measurements showed that the films were safe. When applied to keeping pork fresh, the gelatin/chitosan/Res-CDs film significantly reduced the total viable bacterial count on the pork surface and effectively prevented pork discoloration. Additionally, pH, total volatile basic nitrogen, and weight loss measurements confirmed the preservative effects of the film on pork. This work provides a new approach for synthesizing bionanocomposite films with applicability in the food industry.

Alkoxy Side Chain Engineering in Metal‐Free Covalent Organic Frameworks for Efficient Oxygen Reduction Metal-free covalent organic frameworks (COFs) gain significant attention as catalysts for the oxygen reduction reaction (ORR), a key process in energy conversion technologies like fuel cells and metal-air batteries. While substantial efforts are devoted to unravelling the mechanisms, by which heteroatom-containing building blocks in linkers, vertices, and linkages, enhance catalytic activity and selectivity, the potential of side-chain engineering to modulate pore wall surfaces and optimize the catalytic environment remains largely underexplored. This study investigates the role of alkoxy side chains in modulating the properties of COFs to enhance ORR performance. The synthesized COFs have adjustable pore surfaces, integrating triazine rings and alkoxy groups to enhance channel hydrophilicity by modulating interactions with water molecules. Moreover, the alkoxy side chains act as electron donors through p-π conjugation, creating active and tuneable electronic sites, further enhancing hydrophilicity and facilitating efficient catalytic cycles. Notably, COFs with longer alkoxy side chains exhibit superior ORR activity, with a half-wave potential of 0.77 V, surpassing previously reported metal-free COFs. Theoretical calculations suggest that this enhancement is because of the stronger binding affinity of water molecules and *OOH intermediates to the carbon atoms adjacent to the alkoxy side chains.

Photochemical Conversion of Indazoles into Benzimidazoles Fragment-based drug discovery relies on preparing diverse libraries of advanced building blocks, often incorporating heteroaromatic motifs. Altering the core of heteroaromatics to maximize library diversity typically requires de novo synthesis of each system. This can be often challenging when specific substitution patterns are needed. Here, we introduce a photochemical strategy for the direct permutation of 1H- and 2H-indazoles into benzimidazoles. This transformation exploits the distinct photochemical properties of these heteroaromatics and proceeds under mild conditions. Through systematic experimental and computational studies, we have elucidated a two-step mechanism involving excited-state tautomerization of 1H-indazoles, followed by photochemical rearrangement of the resulting 2H-isomers. This approach demonstrates broad substrate scope, high yields, and compatibility with a variety of functional groups. This method can expand the structural diversity of heterocycle-based libraries through the concept of chemical permutation for heteroaromatic interconversion.
