Cellulose has been widely used in papermaking, textile, and chemical industries due to its diverse sources, environmental friendliness, renewability. Recently, much more attention paid converting cellulose into high-value-added products. Therefore, the extraction of nanocellulose, dissolution cellulose, their applications are some most important research topics currently. However, cellulose's dense hydrogen bond network poses challenges for efficient dissolution, limiting potential functional material development. This review discusses mechanisms disruption weak interactions during nanocellulose dissolution. Key future directions highlighted, emphasizing developing efficient, ecofriendly, cost-effective methods. Additionally, this provides theoretical insights constructing high-performance cellulose-based materials.

Abstract Quantum dots (QDs), with adjustable bandgaps, high interfacial reactivity, and efficient charge transfer, are promising in photocatalytic bacteriostasis. However, challenges like fast recombination, instability, aggregation limit their catalytic efficiency broader applications. A dual‐carrier system of regenerated cationic cellulose (RCC) Ga is first proposed to achieve steady‐state Cu x S QDs quantum confinement, sulfur‐rich vacancies, p‐type Schottky structure, maximizing activity. The junction interface internal electric field accelerate carrier separation, while sulfur vacancies act as hot electron traps, further suppressing electron–hole recombination. Therefore, this ternary composite demonstrates an optimal bandgap (2.25 eV), low electrochemical impedance, extended photoluminescence decay (9.87 ns), broad‐spectrum light absorption, thereby improving conversion into ROS, including 1 O 2 . These reactive species high‐efficiently sterilize E. coli , S. aureus drag‐resistant bacteria, achieving logarithmic removal values 6–8 at a bacterial concentration (10 8 CFU mL −1 ) under visible‐light illumination. Pathogen demise primarily results from photo‐excited which induce instability even substantial damage microbial membranes, leading excessive oxidative stress degradation essential cellular components, superoxide dismutase, catalase, DNA. This study introduces innovative organic/inorganic strategy for designing semiconductor QD‐based disinfection photocatalysts.

Abstract Triboelectric nanogenerators (TENGs), among the most simple and efficient means to harvest mechanical energy, have great potential in renewable energy utilization. While output performance of TENGs is still not high enough, which limits its practical application. Here, a poly(vinylidene fluoride) (PVDF)/fluorinated ethylene propylene nanoparticles (FEP NPs) porous nanofiber (PFPN) membrane with waterproof, breathable, surface superhydrophobic tribo‐negative properties proposed for achieving high‐performance TENGs. The PFPN‐based solid–solid contact PFPN‐TENG achieved an optimal electric net tribo‐charge density 294 µC m −2 , 42.2% more than that polytetrafluoroethylene (PTFE) film. PFNP can maintain best almost no attenuation after 142680 working cycles. Based on excellent triboelectric characteristics, PFPN shows self‐powered body motion sensing harvesting. A flexible solid–liquid achieve electrical average volume power ≈544.1 W −3 by harvesting water wave energy. Such makes it candidate promote blue
