Skin wound healing is a major health care issue. While electric stimulations have been known for decades to be effective facilitating skin recovery, practical applications are still largely limited by the clumsy electrical systems. Here, we report an efficient bandage accelerated healing. On bandage, alternating discrete field generated wearable nanogenerator converting mechanical displacement from movements into electricity. Rat studies demonstrated rapid closure of full-thickness...
The demand for environmental monitoring and remediation stimulates tremendous research efforts to develop highly efficient advanced functional nanomaterials capable of combining multiple functions with the arbitrary switching application scenarios. However, there remains a lack an in-depth comprehensive understanding relationship between properties surface structure nanomaterials, which is crucial design nanomaterials. Here, we present feasibility demonstration single ZnO nanorod-based...
Abstract Endowed with rich terminal groups, good electrical conductivity, and controllable structure, transition metal carbides/nitrides (MXenes) have attracted extensive attention for potential application in gas sensor, but long‐standing challenges of the MXenes (titanium carbide as representative) are their limited selectivity sensitivity. Herein, a high‐active double transition‐metal titanium molybdenum (Mo 2 TiC T x ) superstrong surface adsorption (−3.12 eV) NO molecule is proposed, it...
Hand rehabilitation training and assessment require the frequent participation of professional doctors, which is time-consuming, laborious, sometime non-quantitative. To liberate both doctors patients, a finger motion monitoring glove expected to give helping hand by speed state movement in real time. However, existing gloves suffer from low sensitivity, narrow detection range, lack fabrication consistency. Herein, highly sensitive with an intrinsic surface microstructure fabricated based on...
Abstract Due to its unique band structure and topological properties, the 2D semimetal exhibits potential applications in photoelectric detection, polarization sensitive imaging, Schottky barrier diodes. However, inherent large dark current hinders further improvement of performance semimetal‐based photodetectors. In this study, a van der Waals (vdWs) field effect transistor (FET) composed PdTe 2 transition metal dichalcogenides (TMDs) WSe is fabricated, which high sensitivity detection wide...

We theoretically propose that the van der Waals layered ternary transition metal chalcogenide ${\mathrm{V}}_{2}M{X}_{4}$ ($M=\mathrm{W}$, Mo; $X=\mathrm{S}$, Se) is a new family of quantum anomalous Hall insulators with sizable bulk gap and Chern number $\mathcal{C}=\ensuremath{-}1$. The large topological originates from deep band inversion between spin-up bands contributed by ${d}_{xz}$, ${d}_{yz}$ orbitals V spin-down ${d}_{{z}^{2}}$ orbital $M$ at Fermi level. Remarkably, Curie...
Porous conducting polymer poly(3,4-ethylenedioxythiophene) (PEDOT) nanocomposite prepared on reduced graphene oxide (RGO) film was used as efficient chemiresistor sensor platform for NO2 detection. The comparable electrical performance between RGO and porous PEDOT nanostructure, the large surface area opening structure of this RGO/porous resulted in excellent synergistic effect. gas sensing revealed that, contrast to bare RGO, exhibited enhanced sensitivity (2 orders magnitude) well response...
A graphene-semiconductor heterojunction is very attractive for realizing highly sensitive phototransistors due to the strong absorption of semiconductor layer and fast charge transport in graphene. However, photoresponse usually limited a narrow spectral range determined by bandgap semiconductor. Here, an organic (C60 /pentacene) incorporated on graphene realize broadband (405-1550 nm) phototransistor with high gain 5.2 × 105 response time down 275 µs. The visible near-infrared parts...
We propose a type of pn-junction not formed by impurity-doping, but rather grading the Al composition in an AlxGa1−xN thin film, resulting alternating p and n conducting regions due to polarization charge. By linearly from 0% x (x ≤ 30%) back Al, induced is formed, even absence any impurity doping. X-ray diffraction reciprocal space maps are used determine strain state different graded samples. Polarization doping also provides solution problem p-type efficiency for III-nitrides.
