Herein, a porous binary MoS₂/Co₉S₈ Mott-Schottky hetero-junction as EMW absorbing material was assembled through an atomic-scale doping and chemical etching process. Owing to the precise modulation of the Co²⁺ and Zn²⁺ ion ratios, the electronic structure of the MoS₂/Co₉S₈ interface perfectly was upgraded, successfully obtaining the synthesis of the MoS₂/Co₉S₈@NSCM-X (X = 1, 2, 3) nanocomposites. The optimal MoS₂/Co₉S₈@NSCM-2 exhibited synergetic ehanced dielectric behaviour and impedance matching. Consequently, it displayed a minimum reflection loss (RL_min) of −48.87 dB at a thickness of only 2.0 mm, demonstrating an effective absorption bandwidth (EAB) of 4.64 GHz at high frequencies up to 10.32 GHz. It suggested that atomic-scale doping facilitated the generation of spontaneous electron flow within the MoS₂/Co₉S₈ Mott-Schottky heterojunction, forming an intrinsic electric field, and the diverse defect states on its surface significantly enhanced the multiple scattering of incident EMW. Furthermore, the M/CS-CNT aerogel was assembled from MoS₂/Co₉S₈@NSCM-2, chitosan (CS) and carbon nanotubes (CNTs). Low density, hydrophobicity, high mechanical strength and thus flame retardancy were simultaneously achieved.

Here, we establish a surface-structure engineering strategy to fabricate an air-stable, and highly effective EMI shielding MXene@arginine film. By employing esterification with arginine, hydroxyl groups on the MXene surface were effectively removed, resulting in enhanced air stability. Simultaneously, the arginine modification-induced wrinkled structures created unique pathways that significantly enhanced the EMI shielding performance of the film through the enhanced multi-refection loss. The incorporation of the arginine led to a remarkable retention of 92.2 % in the EMI SE of the film for 193 days in humid atmosphere. Furthermore, the influence of the wrinkled structures on the EM response of the film was explored using finite element simulations, which revealed detailed surface electric field intensity distributions.

Fortunately, all the synthesized prodrugs could be actively loaded into liposomes via Fe³⁺ gradient with high encapsulation efficiency and loading capacity. As the intraliposomal aqueous phase, Fe³⁺ was not only served as the driving force of prodrugs remote loading, but also regarded as an exogenous replenishment to strengthen iron-dependent ferroptosis for multimodal therapy. The length of linkage between CTX and galloyl group played a crucial role in the chemical stability of prodrugs, <em>in vitro</em> drug release rate and <em>in vivo</em> pharmacokinetics behavior of prodrug liposomes. Among three prodrug liposomes, only decylene glycol-bridged CTX-gallic acid (CTX-DC-GA) liposomes kept a good balance between drug leakage during circulation and specific drug release under tumor microenvironment.
