Article Abstract
As advanced optoelectronics continue to integrate, electromagnetic interference (EMI) shielding technologies have been extensively developed to meet multifunctional requirements, including ultrathin, flexible, and transparent properties. In this study, we develop a transparent EMI shielding film by embedding TiCT MXene particles within one-dimensional (1D) metallic fiber structures. This 1D structure facilitates the formation of a percolative network, enabling high EMI shielding performance while maintaining significant visible light transmission. To quantitatively analyze the percolation network-based optoelectronic properties, a rigorous percolation model was employed to investigate the formation of percolative conduction. As a result, the EMI shielding performance reached a shielding effectiveness (SE) value of 45 dB in the X-band (8.2-12.4 GHz) with 64% transmittance, while an SE value of 39 dB was achieved with a transmittance of 86%. Furthermore, the shielding performance remained stable even after 5000 bending cycles, demonstrating sustainable mechanical stability. This multifunctional fiber composite offers valuable insights for advanced optoelectronic applications, providing industrially feasible fabrication methods with good optoelectronic performance.

Rapid strides in portable electronics and telecommunication technologies have sharply escalated the demand for high-performance electromagnetic interference (EMI) shielding materials that effectively suppress secondary electromagnetic pollution while simultaneously integrating thermal management. Here an innovative, lightweight, hierarchical triple-layer aerogel structure comprising nickel (Ni) foam (NiF), titanium carbonitride (TiCNT) MXene, and poly(vinyl alcohol) (PVA), fabricated via a facile, one-step bidirectional freeze-casting process is presented. This asymmetric aerogel architecture strategically employs an impedance-matching MXene/PVA top layer for optimized microwave entry, a NiF/MXene/PVA interlayer introducing magnetic loss and enhancing heat conduction, and a reflective, thermally foamed MXene bottom layer promoting internal reflection for superior energy absorption.

The multiple epidemics of Zika virus (ZIKV) posed a substantial threat to public health. Clinical evidence suggests that ZIKV could break through the blood-brain, blood-placenta, and blood-testis barriers, leading to severe outcomes such as congenital malformations in newborns and Guillain-Barré syndrome in adults. Currently, there are no specific treatments for ZIKV infection.

Current shielding technologies predominantly focus on performance optimization while neglecting fire safety considerations especially in construction building. To address the vulnerability of electromagnetic interference (EMI) shielding materials to accidental fires, we develop sustainable biocarbon/cellulose composites with integrated EMI shielding and flame-retardant capabilities. This approach employs porous biocarbon particles as functional units combined with three-dimensional cellulose networks through hydrogen bonding, van der Waals forces, and physical entanglements.
