The rapid advancement of highly integrated electronics demands next-generation electromagnetic interference (EMI) shielding materials that combine lightweight, ultrathin, flexible, and mechanically robust properties with exceptional shielding effectiveness (SE) to mitigate signal crosstalk and ensure device reliability. In this work, we demonstrate the fabrication of high-performance EMI shields using highly conductive, additive-free aqueous TiCT (T = O, OH, Cl, F) MXene dispersions synthesized under both harsh and mild etching conditions. These dispersions were engineered into freestanding thin films and functionalized cotton fabrics vacuum-assisted filtration, enabling tunable EMI shielding properties through precise control of etchant chemistry, flake size, microstructure, thickness, and MXene loading.

In this work, we find the fault-tolerant metric dimension of a hexagonal nanosheet. This concept ensures robust identity of vertices inside a graph, even in situations in which a few resolving vertices fail. By extending the applicability of this parameter to city systems, we explore its practical use in optimizing emergency reaction and carrier management in cities.

(GPS) is a conditional pathogen that colonizes the upper respiratory tract in pigs and causes Glässer's disease, resulting in high morbidity and mortality in piglets. GPS infection increases the vascular endothelial permeability, but the mechanism has not been fully elucidated. Luteolin (Lut) is a naturally occurring flavonoid found in plants such as vegetables, herbs, and fruits, but its potential to treat the increased vascular endothelial permeability caused by GPS infection has not been evaluated.
