Article Abstract
Microbial fuel cells (MFCs) represent a sustainable energy technology but face limitations such as membrane fouling and reverse voltage in series systems. In this study, a nanoporous cellulose acetate (CA) membrane was fabricated on a polypropylene support using gas pressurization, with glycerin as a plasticizer to induce pore formation. This process yielded uniform, interconnected sponge-like pores while preserving mechanical and thermal stability. The membrane suppressed microbial attachment and organic/inorganic crystallization, ensuring long-term stability. The system achieved a maximum power density of 2.34 W/m and maintained an average of 1.21 W/m over 481 days. Performance remained stable under both series and parallel configurations, highlighting scalability. These findings demonstrate that the developed membrane provides a durable and practical platform for enhancing MFC performance in long-term applications.

The application of aerogels in textiles is limited because their poor moisture permeability and mechanical properties. Aerogel flowers with down-like structures for clothing filling are prepared by laser cutting bacterial cellulose. The nanoporous structures of the aerogels maintained excellent heat preservation performance, and the large pores between flowers provided a channel for water vapor transmission.

Effective wound management relies on dressings that prevent infection and facilitate healing, which has driven research into advanced, cost-effective therapeutic dressings. Bacterial cellulose (BC) is highly valued for use in wound dressings given its mechanical strength, nanoporous structure, high water-holding capacity, and excellent biocompatibility. While BC promotes debridement and maintains moisture for wound healing, it lacks essential bio-functional properties, which can be addressed through incorporation of other compounds.

Phase change materials (PCMs)-integrated solar-thermal-electric generators (STEGs) have emerged as a promising platform for sustainable solar energy harvesting, yet faces critical challenges including liquid phase instability, insufficient photothermal efficiency, and limited thermoelectric output. Herein, we engineered hierarchical photonic confinement through the assembly of plasmonic CuS nanoparticles, broadband-absorbing MoS nanosheets, and porous bacterial cellulose (BC). In this tripartite architecture, BC matrix provides robust structural integrity and enhances heat transfer via its 3D interconnected nanoporous structure; MoS nanosheets enable extended photon harvesting across the ultraviolet to near-infrared spectrum; CuS nanoparticles amplify near-field optical effects through localized surface plasmon resonance.

Hydrogels are promising for moist-electric generator, yet their performance is limited by microscale pores, low charge density, and unstable pore structures. Here, a delignified pomelo peel-confined carboxymethyl cellulose nanofluidic hydrogel is designed to address these limitations. Leveraging the hierarchical porous architecture of delignified pomelo peel, the nanofluidic hydrogel achieves sub-Debye-length nanopores with high stability and charge density.
