The development of singular optics and vortex beams has facilitated novel rotational sensing through the rotational Doppler effect. Researchers in China have pioneered an "optical singularity protractor" for rotation sensing by shifting the research focus from optical vortices to phase singularities. This approach, compatible with traditional sensing probe and enhanced with neuromorphic vision, enables high-speed, high-precision contactless measurement of rotation in complex scenarios. The technique paves a new way for precision sensing and next-generation neuromorphic systems.

Adaptive optics has been introduced into surface plasmon resonance holographic microscopy to achieve background-free near-field quantitative phase imaging. By exploiting the inherent capability of digital holography to obtain the wide-field complex amplitude—particularly the phase distribution—of light waves, we have achieved rapid, accurate, in-situ adaptive correction of wavefront aberrations and high-quality near-field quantitative phase imaging. This research provides a novel aberration correction scheme and imaging methodology for various types of quantitative phase microscopy systems.

Highly loaded magneto-dielectric composite systems are promising for achieving strong electromagnetic loss and structural design flexibility, yet their processability and geometric controllability remain extremely challenging. Herein, a rheologically engineered direct ink writing (DIW) 3D printing strategy is developed. Graphene (Gr) is introduced to reconstruct the particle-loading network, which synergistically improves the ink’s yield behavior, shear-thinning property, structural recovery, and a magnetic–dielectric synergistic loss system is constructed with carbonyl iron powder (CIP). The critical CIP content (~ 84.06 wt%) is determined by the yield model, and a tunable Gr/CIP (GC) composite ink is obtained. The correlation among rheological response, geometric fidelity, and temporal stability is established, enabling high-fidelity 3D-printed gradient honeycomb structures. The rationally designed 3D-printed GC honeycomb (GCH) absorber achieves an effective absorption bandwidth of 18 GHz–4 THz, with an RL_min of − 84.30 dB at a thickness of 2.6 mm. When integrated into device-level terahertz reconfigurable intelligent surfaces (RIS), the GCH absorber contributes to a ~ 3.3 dBi main lobe gain enhancement, 1.9–3.3 dB sidelobe suppression, and a ~ 58% reduction in reflection beamwidth, showing excellent electromagnetic compatibility performance for communication, imaging, and radar. This work offers a practical strategy for the structural fabrication and device integration of high-load magneto-dielectric synergistic absorbers.

Developing cathodes that simultaneously deliver high capacity, superior rate capability, and long-term cycling stability remains a major challenge in lithium-ion batteries. Here, we report a high-performance textile cathode constructed via interfacial interaction-mediated assembly of high-energy porphyrin (PP) ligand-stabilized LiFePO₄ nanoparticles (LFP NPs). For this, 19 nm LFP NPs with olivine-type intercalation mechanism were covalently integrated with amine-functionalized PP to enable multi-electron redox activity, followed by encapsulation with multi-walled carbon nanotube (MWCNT) multilayers. Subsequent thermal annealing transformed the MWCNT layers into a covalently cross-linked conductive network. As a result, the textile cathode delivers an unprecedented specific capacity of ~260 mAh g⁻¹ at ~0.1 C, excellent rate capability, and retains over 93% of its initial capacity after 2,000 cycles at 1 C with nearly 100% Coulombic efficiency. This work highlights interfacial interaction-mediated ligand assembly as a powerful strategy for next-generation high-capacity and durable cathodes.
