Wide bandgap (WBG) mixed-halide perovskites are promising candidates for tandem and semitransparent solar cells owing to the increased VOC and the controllable optical properties arising from engineered mixed halide compositions. However, their stability is hindered by photoinduced halide segregation, causing phase instability and long-term degradation. In this work, we comp…
Moisture-enabled generators (MEGs) often suffer from low power output and limited durability. Here, we develop a high-performance MEG based on a novel NMS/CS aerogel integrating hollow mesoporous carbon (MC), polypyrrole (PPy), polystyrene sulfonate (PSS), and chitosan (CS). By precisely tuning solvent ratios and surface potentials, dual ionic and pore gradients are constructed…
Water-soluble conjugated molecular materials (WSCMs) have exhibited hierarchical light harvesting, energy transfer, photosensitization, and photoconversion capabilities, thus achieving remarkable breakthroughs in disease-related biosensing, biotheranostics, and biophotoconversion. In contrast to the basic investigations, rare efforts have been devoted to truly realizing their b…
Ion-selective membranes are among the most vital components in separation processes and electrochemical devices, such as seawater desalination and flow batteries. To overcome the permeability and selectivity trade-off of membranes, the construction of angstrom-scale transport pathways within ultrashort structures is essential. Herein, we report a novel gelation-phase separation…
Due to their exceptional charge transport properties, defect tolerance, and solution-processing advantages, metal halide perovskites have become versatile semiconductor materials for optoelectronic applications.

In this process, waste tires form…
Kirigami metamaterials, formed by introducing cuts into planar sheets, can exhibit bistability through geometry-dependent energy landscapes. Designing structures with prescribed energy barriers and target deformation states is therefore essential for programmable mechanical functionality. Here, we present a physics-informed neural network (PINN) framework that does not require …
Surface acoustic wave (SAW) devices, particularly of the Rayleigh type, harness nanoscale-amplitude vibrations on a piezoelectric substrate to sense, actuate and process various targets. SAW modulation in selected areas is essential for high-performance devices. Here, we develop a highly entangled glycerol hydrogel as a compact, high-efficiency absorber for wave modulation of R…
Elastic wood sponges are sustainable, low-cost, and multifunctional materials that have gained extensive attention and rapid development. However, their dense cell walls and fragile cellulose skeleton severely constrain the compressive recoverability and fatigue resistance. This constraint hinders their use as an elastic functional material toward high-performance, advanced app…
Bistable architected metamaterials exploit geometric instability to enable snap-through switching, programmable mechanical response, and reconfigurable deformation, making them attractive for soft robotics, deployable structures, and shape-morphing systems. Nevertheless, many existing bistable architected metamaterials rely on axial compression, tension, or torsion to trigger b…
Natural fibers have evolved through optimized biosynthetic pathways to achieve an exceptional combination of strength, toughness, and compliance.

The α-phase of formamidinium lead iodide (α-FAPbI3) perovskite has a promising bandgap for efficient single-junction photovoltaics. However, its large A-site FA+ cation destabilizes the perovskite lattice, favoring transformation into non-perovskite δ-phases under ambient conditions. To overcome this instability, compositional A-site engineering with Cs+, Rb+, and M…
