Abstract Healable, adhesive, wearable, and soft human‐motion sensors for ultrasensitive human–machine interaction healthcare monitoring are successfully assembled from conductive human‐friendly hybrid hydrogels with reliable self‐healing capability robust self‐adhesiveness. The conductive, healable, self‐adhesive network prepared the delicate conformal coating of functionalized single‐wall carbon nanotube (FSWCNT) networks by dynamic supramolecular cross‐linking among FSWCNT, biocompatible...
Abstract Utilizing mechanical energy to produce hydrogen is emerging as a promising way generate renewable energy, but challenged by low efficiency and scanty cognition. In this work, graphitic carbon nitride (g‐C 3 N 4 ) with an atomically thin sheet‐like structure applied for prominent piezocatalytic photo‐enhanced H 2 production. It revealed that the anomalous piezoelectricity in g‐C originates from strong in‐plane polarization along ‐axis, contributed superimposed polar tri‐s‐triazine...
Hydrostatic pressure, as an alternative of chemical pressure to tune the crystal structure and physical properties, is a significant technique for novel function material design fundamental research. In this article, we report phase stability visible light response organolead bromide perovskite, CH3NH3PbBr3 (MAPbBr3), under hydrostatic up 34 GPa at room temperature. Two transformations below 2 (from Pm3̅m Im3̅, then Pnma) reversible amorphization starting from about were observed, which...
Exposure of anisotropic crystal facets allows the directional transfer photoexcited electrons (e- ) and holes (h+ ), for spatial charge separation. High-index with a high density low-coordinated atoms always serve as reactive catalytic sites. However, preparation multi-facets or high-index is highly challenging layered bismuth-based photocatalysts.

Novel inorganic lead-free double perovskites with improved stability are regarded as alternatives to state-of-art hybrid lead halide in photovoltaic devices. The recently discovered Cs2 AgBiBr6 perovskite exhibits attractive optical and electronic features, making it promising for various optoelectronic applications. However, its practical performance is hampered by the large band gap. In this work, remarkable gap narrowing of is, first time, achieved on through high pressure treatments....
Transition-metal dichalcogenides, such as tungsten disulfide (WS2) and molybdenium (MoS2), are highly anisotropic layered materials have attracted growing interest from basic research to practical applications due their exotic physical property that may complement graphene other semiconductor materials. WS2 nanosheets found exhibit broadband nonlinear saturable absorption property, absorbers (SAs) fabricated by depositing on side-polished fibers. Attributing the weak evanescent field long...
An organic-inorganic halide perovskite of CH3NH3SnI3 with significantly improved structural stability is obtained via pressure-induced amorphization and recrystallization. In situ high-pressure resistance measurements reveal an increased electrical conductivity by 300% in the pressure-treated perovskite. Photocurrent also a substantial enhancement visible-light responsiveness. The mechanism underlying enhanced properties demonstrated to be associated stability.
A large coercive field (EC) and ultrahigh piezoelectricity are essential for ferroelectrics used in high-drive electromechanical applications. The discovery of relaxor-PbTiO3 crystals is a recent breakthrough; they currently afford the highest piezoelectricity, but usually with low EC. Such performance deterioration occurs because high interlinked an easy polarization rotation, subsequently favoring dipole switch under small fields. Therefore, search both EC has become imminent challenge....
Realization of highly tunable second-order nonlinear optical responses, e.g., second-harmonic generation and bulk photovoltaic effect, is critical for developing modern optoelectronic devices. Recently, the van der Waals niobium oxide dihalides are discovered to exhibit unusually large generation. However, physical origin possible tunability responses in these materials remain be unclear. In this article, we reveal that NbOX2 (X = Cl, Br, I) may partially contributed by band nesting effect...

The pre-training of text encoders normally processes as a sequence tokens corresponding to small units, such word pieces in English and characters Chinese. It omits information carried by larger granularity, thus the cannot easily adapt certain combinations characters. This leads loss important semantic information, which is especially problematic for Chinese because language does not have explicit boundaries. In this paper, we propose ZEN, BERT-based encoder enhanced n-gram representations,...
