The rapid development of multispectral detection technology urgently requires the simultaneous suppression of microwave and infrared (IR) signatures. However, conventional strategies suffer from limited functional integration, complex structures, and poor scalability in achieving synergistic control of radar cross section (RCS) and IR radiation characteristics. Herein, we propose a chaotic paradigm combined with a multi-scale strategy to address radar-IR-optical multispectral stealth by using a single-layer coding indium tin oxide (ITO) platform. This architecture covers millimeter-scale representative elements, centimeter-scale phase-coded subarrays, and decimeter-scale meta-arrays, with a direct correlation established between chaotic initial conditions and microwave/IR responses theoretically. Specifically, chaotic coding, a deterministic pseudo-random coding method, is adopted to construct a meta-array inspired by sensitivity of chaotic systems to initial conditions. Tuning chaotic initial parameters enables controllable spatial IR emissivity modulation while preserving broadband intrinsic microwave diffusion due to the multi-wavevector mechanism. For verification, a proof-of-concept metadevice is fabricated, and experimental results manifested a broadband RCS reduction over 10 dB within X/Ku bands (8 ~ 18 GHz) for incident angles up to 45°, with a low IR emissivity below 0.3 and a high optical transmittance of 71.2%. Featuring ultrathin profile (3.35 mm, ~ 0.09 λL), light weight, optical transparency, and facile fabrication, our strategy offers a promising avenue for multi-scale multispectral stealth applications.

A ZIF-90 nanocarrier delivers dinotefuran and suppresses NlABCG3 and NlABCH1 in resistant Nilaparvata lugens . This system combines pH/ATP-triggered release with enhanced foliar retention, improving efficacy while sparing honeybees and promoting rice growth, offering a promising resistance-breaking strategy. ABSTRACT ATP-binding cassette (ABC) transporters, by mediating drug efflux, have emerged as a major driver of insecticide resistance in agricultural pests, yet direct countermeasures against this defense mechanism remain scarce. Here, we report that zeolitic imidazole framework-90 (ZIF-90) can serve as a functional insecticide carrier to overcome resistance by interfering with ABC transporters. Dinotefuran-loaded ZIF-90 (Din@ZIF-90) was synthesized via a simple and rapid one-pot method and exhibited significantly enhanced toxicity against Din-resistant Nilaparvata lugens . Mechanistically, the nanoformulation selectively inhibited the expression of NlABCG3 and NlABCH1 , two ABC transporter genes involved in Din resistance, as validated by RNAi. Molecular docking further confirmed the binding potential of Din with the NlABCG3 and NlABCH1 proteins, establishing their functional roles in efflux-based resistance. In addition, Din@ZIF-90 afforded enhanced photostability, pH/ATP-responsive release, superior leaf adhesion, and preserved systemic movement in rice. The nanoformulation also exhibited markedly lower acute contact toxicity to honeybees and was biocompatible with rice, promoting seedling growth. This work presents a novel nanotechnology-based strategy to combat insecticide resistance through targeted modulation of ABC transporters.

When it comes to training footwear, performance will always come first. But increasingly, today’s gym-goers want shoes that perform under pressure while making a statement beyond the weight rack. Reebok understands that balance better than most, and its latest update to the acclaimed Nano X5 Edge proves that functional fitness footwear doesn’t have to play […]
