Carbon Nanocage-in-Microcage Structure With Tunable Carbon-Coated Nickel as a Microwave Absorber With Infrared Stealth Property.
Article in Advanced science (Weinheim, Baden-Wurttemberg, Germany), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The rational design of microwave absorption (MA) material featuring light weight, wide absorption bandwidth, and infrared stealth property is crucial for military stealth and health protection but remains challenging. Herein, an innovative N-doped carbon nanocage-in-microcage structure with tunable carbon-coated Ni (NC/Ni(HS)) is reported via a reliable Ni-catalyzed and Ni-templated method. The hierarchically hollow structure of nanocage-in-microcage composites can optimize the impedance matching and respond to multiple reflections and scattering of incident microwaves and infrared waves. Moreover, the magnetic Ni nanoparticles improve the synergistic interactions between confined heterointerfaces and promote interfacial polarization. Such an ingenious structure endows NC/Ni(HS) with outstanding MA performance and infrared stealth properties. Specifically, NC/Ni(HS)-10 with an optimal dielectric property, exhibits excellent MA performance. At an ultralow fill loading of 4 wt.%, a wide absorption bandwidth of 6.16 GHz is achieved at a thickness of 2.63 mm, and a strong reflection loss of -63.67 dB is obtained at a thickness of 2.00 mm. In addition, NC/Ni(HS)-10 shows a low infrared emissivity in the range of 3‒14 µm, which is the key to compatibility with infrared stealth. This work paves the way for the design of advanced MA materials that meet the requirements of multispectral-compatible stealth.
