Atmospheric particulate matter pollution poses significant threats to human health and the environment. Submicron-fiber filtration materials have received widespread attention owing their ultrafine dimensions, high porosity, precise interception capabilities. However, low dust-holding capacity rapid resistance increase during use remain challenges. In this study, a modular helical linear free-surface multi-jet electrospinning device was employed prepare multi-scale fibers (80–800 nm) combine them with melt-blown non-woven fabrics in single-step process, creating three-dimensional gradient hierarchical material (3D-MNFG). The 3D-MNFG exhibits layered structure pore sizes transitioning from 18–32 μm 0.5–2.4 μm, 0.3–0.4 μm. Under an initial pressure decrease of 90 ± 3 Pa, it achieves efficiency (97%) quality factor 0.038 Pa−1, even after electrostatic treatment. Furthermore, novel overcomes limitations existing submicron-fiber membranes by offering dust holding 22.02 g/m2. dynamic tests at air velocities (28 m/s), its increased gradually, reaching lifespan limit (450 Pa) 29 d, significantly outperforming materials, which saturated within 8 d. Simulations validate synergistic mechanism micro/nano-fibers. fabricated shows promising potential for industrial production commercial applications.

The study aimed to develop immunomodulatory silver nanoparticles (CHT-PCT/AgNPs) using a green chemistry approach with Umbilicaria esculenta (U.E.) extract protect neurons from Parkinson's disease. synthesized CHT-PCT/AgNPs measured 88.2 ± 33.7 nm in size, zeta potential of approximately 24.5 1.9 mV. In vitro assays demonstrated that the green-synthesized exhibited greater biocompatibility and antioxidant properties compared chemically AgNPs. MTT assay indicated were cytocompatible up 50 μg/mL, but higher concentrations resulted significant toxicity. DPPH revealed dose-dependent activity, although it was lower than ascorbic acid. animal studies MPTP-induced Parkinsonism, count tyrosine hydroxylase (TH)-positive cells varied across groups, healthy controls showing 145.3 11.0 negative control group only 21.6 4.1. Additionally, number DRD1-positive also reflected similar trend. These findings suggest may serve as neuroprotective agent mitigate
