Large-Scale Nanofiber Manufacturing| Lotus leaf-inspired poly(lactic acid)nanofibrous membranes with enhancedhumidity resistance for superefficient PMfiltration and high-sensitivity passivemonitoring 2025-05-09

Particulate matter (PM) pollution in air poses significant challenges for modern society, severely damaging ecological environments, hindering precision manufacturing development, and even threatening human health. Due to their extremely small size and complex composition, PMs easily carry and spread bacteria and viruses, posing major risks to respiratory safety and cardiovascular systems. Biodegradable polylactic acid (PLA) nanofiber membranes (NFMs) show great potential in addressing increasing airborne PMs and plastic/microplastic pollution, but still suffer from poor electret effects, dielectric properties, and surface activity - especially rapid charge dissipation under high humidity, presenting challenges for long-term respiratory protection.

Large-Scale Nanofiber Manufacturing| Anisotropic structure of nanofiber hydrogel accelerates diabetic woundhealing via triadic synergy ofimmune-angiogenic-neurogenic microenvironments 2025-05-09

Diabetic wounds are chronic and difficult-to-heal wounds whose complex inhibitory microenvironment is dominated by hyperglycemia, hypoxia, and persistent inflammation, leading to various cellular dysfunctions. The wound healing process involves multiple complex and overlapping stages including hemostasis, inflammation, proliferation, and remodeling. However, due to microenvironment imbalance, these stages are often disrupted in diabetic wounds, resulting in impaired healing. Currently, with the rapid development of tissue engineering, designing bioactive materials loaded with instructive signals to effectively regulate multicellular functions and remodel multidimensional microenvironments has become a promising strategy for diabetic wound repair.

Large-Scale Nanofiber Manufacturing| Parallel+uniaxial” conjugatedelectrospinning for dual-functionanalogous-tricolor microfiber film withmulticolor emission and magnetism 2025-05-09

Lead halide perovskite CsPbX3 (X = Cl, Br, I) quantum dots (QDs) have attracted researchers' interest due to their applications in light-emitting diodes (LEDs), solar cells, fluorescent sensors, and photocatalysis. However, to further expand their applications, developing multifunctional materials based on perovskite QDs is significant. Notably, conventional preparation methods often directly blend different functional substances, which may cause undesirable interactions that compromise multifunctionality. Therefore, it's necessary to design and construct special one-dimensional structures that effectively separate luminescent substances from dark magnetic materials or different perovskite QD components at the microscale to avoid direct contact and achieve better multifunctionality.

Large-Scale Nanofiber Manufacturing| Electrospinning-based carbon black/BiOBrhierarchical porous fibrous membranes forvisible-light driven solar vapor generationand antibiotics degradation 2025-05-08

Interfacial solar steam generation (ISSG) is a promising strategy for freshwater production. However, when treating wastewater containing organic pollutants, these organics become concentrated in photothermal materials and mother liquor during evaporation, not only shortening evaporator lifespan but also potentially creating new environmental issues if improperly handled. Combining ISSG with photocatalytic technology can improve light-to-vapor conversion efficiency through photothermal effects, while localized heat accelerates charge transfer in catalytic reactions, enhancing pollutant removal efficiency. Yet preparing efficient, stable, and durable bifunctional solar evaporators remains challenging.
