Herein, we demonstrate a novel halogen-bonding driven self-assembly strategy to fabricate B/N/Cl-rich layered 3D carbon nanosheet stacks, where chloroethyl amine derivatives (CAH) and ammonium pentaborate (AP) serve as C/Cl/N sources and B-containing 2D template, respectively. The halogen-bonding drives CAH and AP to construct an interconnected 3D network, endowing high B/N/Cl-codoped and layer-by-layer stacked wrinkle carbon nanosheets (ClBNC-850) with hierarchically porous structure. The resultant ClBNC-850 cathode with chlorine doping effect is pioneeringly introduced in ZISC, exampling a cogent model to clarify the cooperative effect of chlorine-induced defects and layer-stacked nanosheets for carbons in ZICS, achieving high capacity (220 mAh g⁻¹ at 1.0 A g⁻¹) and energy density (225 Wh kg⁻¹ at 1122 W kg⁻¹), good flexibility, surpassing the recently reported carbon-based ZICS. Meanwhile, the ex-situ characterizations and theoretical calculations reveal that the chlorine-induced defects engineering can adjust the electronic structures of the B/N-doped carbons, as active centers, enhance accessibility and adsorption-capacity of Zn²⁺.

However, producing high-quality WBG perovskite thin films through vapor-based techniques is challenging, primarily due to the difficulties in controlling the stoichiometric ratios and achieving uniform distribution of organic and inorganic ions. In this research, we meticulously control the doping levels of Cs and Br during the evaporation of inorganic precursors, resulting in perovskite films with optimal bandgaps for tandem applications. Then, by employing vapor-assisted pressure-controlled annealing (VA-PCA) with a combination of 4-fluorophenylmethylammonium bromide (F-PMABr) and ammonium fluoride (NH₄F), we achieve homogeneous, pinhole-free WBG perovskite films of exceptional quality. This method synergistically addresses both surface and bulk defects. The incorporation of small ions and molecules mitigates halide vacancy defects and fortifies the lattice structure, effectively curbing detrimental ion migration and minimizing phase segregation in WBG perovskites. Consequently, the highest power conversion efficiency achieved by our fabricated inverted WBG perovskite solar cell is 20.10 %.

As a candidate solution, magnetorheological (MR) materials, capable of flexibly regulating damping and stiffness by through external magnetic field to prevent system resonance, face limitations in their energy absorption efficiency due to significant deformation under harsh impacts. To address this, the unique mechanical properties of mechanical metamaterials, exemplified by compression-torsion metamaterial (CTM), offer a promising strategy. Inspired by the energy absorption of myocardial torsion, we propose an innovative MRE/MRF absorber merged CTM. The layered structure, where the external CTM layer drives the torsional deformation of the internal MRE/MRF layer, can synergistically modulate the elastic modulus and shear modulus, thereby enhancing the energy absorption efficiency. Through theoretical analysis and simulations, optimal geometric parameters of CTM were determined, achieving a torsional absorption ratio of 21.64 %. Under simulated continuous vibration on a small-scale vibro-stand, the natural frequency was shifted from 32 Hz to 65 Hz, and the vibration acceleration attenuation rate reached 75.5 %, after applying the magnetic field. To achieve vibration identification under harsh impact, a direct current triboelectric nanogenerator (DC-TENG) sensor based on torsional deformation is designed in the interface gap between the two layers. In large-size vibro-stand tests simulating harsh impact (1<em><strong>-</strong></em>6 g), the DC-TENG sensor triggered a high voltage signal during instantaneous torsional deformation (<em><strong>a</strong></em>≥3 g), enabling magnetic field modulation and achieving an impact energy absorption efficiency of 48 %. Finally, the practical utility of this absorber was further illustrated in the context of the unmanned aerial vehicle (UAV) forced landing, where its installation increased the safe forced landing height of the UAV by 33 % (from 60 cm to 80 cm), while maintaining an impact energy absorption efficiency of 40 %.

Nevertheless, the recognition accuracy is only improved from the perspective of designing sensor structure and optimizing working mode. To address these challenges, we developed a triboelectric material/electrode interface structure design strategy that can enhance the identification accuracy of TENG-based tactile sensor. Thus, a novel TENG device with elastic polymer-encapsulated metal material structure was fabricated. Cu-plated nonwoven is fabricated and used as electrodes, which are characterized by an unordered structure with a large number of pores formed between the fibers, greatly increasing the specific surface area. There is no orientation at the micron scale, avoiding distortion of the stress-signal feature relationship. Besides, the structure of elastic polydimethylsiloxane (PDMS)-encapsulated Cu-plated nonwoven fabric results in the stability of the output signal waveform under extreme environments, which assisted in improving the durability of the output voltage and signal waveform under extreme environments. More importantly, the separation and compression between the object and triboelectric material led to the flow of electrostatic electrons and the formation of unique output signals and self-powered power. There is a clear internal relationship between the triboelectric signal feature and the material characteristics. As expected, the accuracy of identifying different materials and palms after R-CNN model training reaches 98.3 % and 98.75 %, respectively.
