Summary: The application of nanofiber and porous metal-organic framework for public health protection has gained increasing attention. A composite platform with lightweight and multifunctionality has been developed, providing physical sieving and gas capturing capabilities. By optimizing the fabrication process, a hybrid membrane comprised of nanofibers and MOF particles has been produced. The order of processing steps was varied to study its effect on air pollutant filtration, and the most desirable configuration for personal protection equipment was found to balance air permeability, filtration efficiency, and performance.

Summary: Air filtration technology has been continuously improved to mitigate pollution caused by particulate matter (PMs) and yellow dust, but small-sized airborne contaminants like PM2.5 and toxic gases such as volatile organic compounds (VOCs) still remain in the atmosphere and significantly impact human health. Therefore, there is a need for an integrated filtration system that can detect and remove various airborne pollutants without interference from airflow. In this study, a hybrid air filtration system was designed, consisting of a colorimetric multi-scale nanofiber (NF)/nanonet (NN) membrane and a metal-organic framework (MOF)-decorated mesh substrate, to effectively remove PM2.5 and toxic gases in the air.

Summary: Flexible fiber membranes with conducting polymer graphene quantum dots (GQDs) and TiO2 show high photocatalytic activity for the degradation of organic pollutants. The combination of GQDs and TiO2 broadens the optical response threshold and reduces the energy required for electron transfer. The interface charge transfer mechanism between GQDs/TiO2 and conducting polymer follows a Z-scheme heterojunction, maximizing the retention of strong reducing electrons and oxidation holes.

Summary: Inspired by the Collocalia birds, we propose a technique to prepare Janus composite nanofiber membrane in one step by pouring large-particles of self-gelling powders onto nanofibers during the spinning flight path. This membrane material has strong adhesion and can gel at 5.3 seconds, without the need to wipe up the blood on the wet tissue beforehand. Compared to medical gauze and commercially available gelatin hemostatic sponges, this membrane reduces the hemostasis time to 1/5 (1.16 +/- 0.28 min) and the blood loss to 1/3 (111 +/- 11 mg). Furthermore, it has the potential for large-scale production and is expected to become a new commercially available material for hemostasis in the future.
