Abstract Metal single atoms (SA)‐support interactions inherently exhibit significant electrochemical activity, demonstrating potential in energy catalysis. However, leveraging these to modulate electronic properties and extend application fields is a formidable challenge, demanding in‐depth understanding quantitative control of atomic‐scale interactions. Herein, situ, off‐axis electron holography technique utilized directly visualize the between SAs graphene surface. These facilitate formation dispersed nanoscale regions with high charge density are highly sensitive external electromagnetic (EM) fields, resulting controllable dynamic relaxation processes for accumulation restoration. This leads customized dielectric relaxation, which difficult achieve current band engineering methods. Moreover, behaviors insensitive elevated temperatures, having characteristics distinct from those typical metallic or semiconducting materials. Based on results, programmable EM wave absorption achieved by developing library SA‐graphene materials precisely controlling SA‐support tailor their responses waves terms frequency intensity. advancement addresses anti‐EM interference requirements components, greatly enhancing development integrated circuits micro‐nano chips. Future efforts will concentrate manipulating atomic SA‐support, potentially revolutionizing nanoelectronics optoelectronics.

Abstract Despite considerable efforts to tune the morphology and composition from macroscopic level nanoscale of electromagnetic wave‐absorbing materials (EWMs), achieving strong wide‐bandwidth absorption under a temperature‐variant environment remains extremely difficult due temperature‐sensitive electromagnetic‐absorbing mechanisms that involve dipole polarization conductive loss. Here, by integrating highly carbon nanotubes (CNTs) networks temperature‐stable silicon nitride (Si 3 N 4 ) protective layer, CNTs/amorphous carbon@Si (C‐CNT‐Si porous foam composed sandwich‐like Si /C‐CNT/Si strut, which exhibits excellent temperature‐insensitive properties room temperature 600 °C, is demonstrated. To be specific, value minimum reflection loss always lower than −50 dB, effective absorbing bandwidth covering whole X band throughout thickness range 4.8–6.1 mm achieved. The superior property synergistic effects irregular derived lattice vacancies heterogeneous interface, slightly increased decreasing carrier mobility, increasing concentration rising environment.

Abstract High-performance Ti 3 C 2 T x fibers have garnered significant potential for smart enabled fabrics. Nonetheless, a major challenge hindering their widespread use is the lack of strong interlayer interactions between nanosheets within fibers, which restricts properties.
