However, the rational design of cathode materials rich in active sites for efficient Zn²⁺ storage remains challenging. Through a hierarchical modulation strategy designed to synergistically optimize the pore structure and surface chemistry of carbon material, we develop a N/P/O co-doped, coal tar pitch (CTP)-derived hierarchically porous carbon (NP-OPC) for effectively zinc storage. Acid oxidation effectively suppresses polycondensation of CTP, while pre-carbonization with N/P dopant generates an initial porous framework in the carbon precursor and a heteroatom-affine environment, collectively enhancing the efficiency of KOH activation and promoting heteroatom doping during carbonization. The resulting NP-OPC possesses a well-developed hierarchical porosity, an ultrahigh surface area of 3522.2 m² g⁻¹, and substantial heteroatom doping of N (∼6.12 at.%), P (∼2.07 at.%), and O (∼8.14 at.%). The structural properties provide sufficient active sites for Zn²⁺ adsorption, rapid ion/electron transport, and optimized surface physicochemical properties. Consequently, the NP-OPC based aqueous ZHC delivers an exceptional capacity of 207.3 mAh g⁻¹ at 0.2 A g⁻¹ and exhibits exceptional cycling stability, retaining 91.1% of its initial capacity after 30,000 cycles at 10 A g⁻¹. Moreover, the assembled pouch device achieves both high energy density (138.6 Wh kg⁻¹) and superior durability (89.5% capacity retention after 70,000 cycles at 10 A g⁻¹). Through <em>ex situ</em> analyses and theoretical calculations, we elucidate the charge storage mechanism and identify the origin of the enhanced performance.

The architectural engineering of hierarchical gradient heterostructures has emerged as a pivotal strategy for optimizing electromagnetic attenuation. In this study, fiber composites featuring spatially-tuned gradient hierarchies were strategically constructed by a combination of electrostatic spinning, sequential solvent heat treatment, and thermal treatment. Multi-channel carbon nanofibers (MCNFs) serve as the structural scaffold, while spinel NiCo₂O₄ nanoarrays with distinct morphologies (lamellar, acicular, and tubular) function as the intermediate layer to template the subsequent growth of multiphase MnO₂ shell. The morphological evolution of the NiCo₂O₄ layer dictates the spatial distribution and interfacial density of the MnO₂ nanoarrays, thereby enabling precise modulation of the impedance matching and dielectric relaxation properties. The tubular gradient configuration (MNCF-T2) exhibits superior electromagnetic wave attenuation by leveraging the synergistic coupling of intensified Maxwell-Wagner interfacial polarization, multi-component dipole relaxation, and enhanced internal reflections within the hollow-fiber hierarchy. Consequently, the material achieves an optimal reflection loss of −65.9 dB and an effective absorption bandwidth of 7.84 GHz.

This review examines a carbon nano emitter–manipulator system in which collective electronic, photonic, and plasmonic excitations enable tunable wave generation and directional transfer across confined dimensions. By integrating atomically engineered carbon architectures with external field modulation, the framework achieves dynamic control over emission frequency, phase coherence, and propagation pathways. The model unifies wave emission and transfer through a coupled Hamiltonian description, linking carrier mobility, structural confinement, and dissipative environments. Scaling analysis reveals size-dependent temporal dynamics, suggesting that effective time constants emerge from motion across hierarchical length scales. Such behavior provides a route to adaptive nano emitters capable of manipulating information flow, energy localization, and transduction efficiency. The discussed concepts are relevant to nano-optoelectronics, quantum communication, and carbon-based metamaterials, offering a transferable theoretical foundation for designing multifunctional wave-emitting systems with high stability, controllability, and integration potential.

Nevertheless, practical implementation is hindered by rapid capacity fading, which is hampered primarily by sulfur's inherent limitations, such as its poor electrical conductivity, volume expansion of sulfur, the dissolution of intermediate polysulfide species and slow Na-S redox kinetics. In this work, we present a sulfur cathode encapsulated within nitrogen/oxygen/phosphorous co-doped hollow carbon nanofibers (NOP-HCFs) to effectively trap polysulfides, achieving experimentally high specific capacity and outstanding electrochemcial cycling performance. The NOP-HCFs were fabricated via coaxial electrospinning of poly(methyl methacrylate)/polyacrylonitrile (PMMA-core/PAN-shell) design fibers, using triphenylphosphine (TPP) as the phosphorous source, followed by a one-step thermal carbonization process. The three-dimensional nonwoven structure of NOP-HCFs facilitates rapid electron and ion transport, while co-doping with heteroatoms (N/O/P) promotes the polysulfide conversion reactions by providing effective chemisorption sites and catalytic activity. Consequently, RT Na-S batteries employing NOP-HCFs/S cathode attained a specific capacity of 1077.5 mAh g⁻¹ at 0.2 C and demonstrated remarkable stability, sustaining 924.2 mAh g⁻¹ over 300 cycles. Furthermore, it demonstrated excellent performance at high rates (695.1 mAh g⁻¹ at 2 C).
