Carbon-based nanofibers are critical materials with broad applications in industries such as energy, filtration, and biomedical devices. Polyacrylonitrile (PAN) is a primary precursor for carbon nanofibers, but conventional electrospinning techniques typically operate at low production rates of 0.1-1 mL/h from single spinneret, limiting scalability. In this study, we introduce novel liquid-assisted ultrahigh-speed (LAUHS-ES) technique that achieved actual over 220 times faster than methods. This dramatic increase throughput through Taylor cone stabilization using thin layer liquid sheath, allowing without compromising the structural integrity or uniformity nanofibers. Comprehensive characterization, including scanning electron microscopy (SEM), atomic force (AFM), Fourier-transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), confirmed high quality, consistency, crystallinity produced Our results demonstrate PAN nanofiber fabrication can be scaled up significantly while maintaining precise control fiber morphology performance. advancement holds substantial promise large-scale industrial applications, enabling more efficient cost-effective carbon-based

Highly sensitive photoelectrochemical (PEC) sensors for trace carcinogens, such as heavy metal chromium(VI) [Cr(VI)] and antibiotic tetracycline (TC) are crucial. Herein, by integration of photoactive redox phosphomolybdates with conjugated organic components, types dual-mode PEC were synthesized sensing Cr(VI) TC pollutants, formulas (H
