Abstract Developing high‐efficiency and stable bifunctional electrocatalysts for water splitting remains a great challenge. Herein, NiMoO 4 nanowires as sacrificial templates to synthesize Mo‐doped NiFe Prussian blue analogs are employed, which can be easily phosphorized Fe 2x Ni 2(1‐x) P nanotubes (Mo‐FeNiP NTs). This synthesis method enables the controlled etching of that results in unique hollow nanotube architecture. As catalyst, Mo‐FeNiP NTs present lower overpotential Tafel slope 151.3...
We present a fiber-optic microphone (FOM) based on graphene oxide (GO) membrane in this study. A Fabry-Perot cavity consisting of single-mode fiber and piece GO works as the acoustic sensing structure. Using core component, fabricating process FOM is demonstrated to be simple efficient. Acoustic tests show that achieves an average minimum detectable pressure 10.2 μPa/Hz <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">1/2</sup> , while...
Abstract Circuits based on organic electrochemical transistors (OECTs) have great potential in the fields of biosensors and artificial neural computation due to their biocompatibility similarity. However, integration OECT‐based circuits lags far behind other emerging electronics. Here, ternary inverters antiambipolar vertical OECTs (vOECTs) with establishment networks are demonstrated. Specifically, by adopting a small molecule (t‐gdiPDI) as channel vOECT, high performance, current density...
Nitrogen doping is a promising method to modulate the electrical properties of graphene. However, reported nitrogen-doped graphene (NG) films usually show low electron concentration and carrier mobility. In this study, we have demonstrated chemical vapour deposition NG films, where melamine was used as sole source both carbon nitrogen. The studies that nitrogen content configurations are strongly dependent on growth temperature. At temperature 990 °C, total N graphitic-N/total simultaneously...
In this study, the separator coated with reduced graphene oxide (rGO) layer is prepared via doctor blading. The lithium-sulfur (Li-S) battery rGO-coated exhibits much smaller impedance and better electrochemical performance. After rGO, initial discharge capacity can be as large 1067 mAh g−1 at 0.2 C which retain 878 after 100 cycles, reach 710 even 2 C. significant performance enhancement attributed to bi-functionality of rGO; rGO coating has unique porous structure, high conductivity...
Abstract Pulse generation often requires a stabilized cavity and its corresponding mode structure for initial phase-locking. Contrastingly, modeless cavity-free random lasers provide new possibilities high quantum efficiency lasing that could potentially be widely tunable spectrally temporally. in lasers, however, has remained elusive since the discovery of gain lasing. Here we report coherent pulse with based on unique polarization selectivity broadband saturable absorption monolayer...

Vertical organic electrochemical transistors (vOECTs) have received widespread attention in bioelectronics, wearable, and neuromorphic electronics due to their high transconductance (gm), low driving voltage, biocompatibility. As key parameters of vOECTs, gm switching speed (or transient time, τ) are vital for achieving satisfying performance various practical applications. Here we employ vOECTs with varying top electrode widths effective modulation. It is found that both τ increase linearly...
Channel patterning precision in vOECTs enables efficient modulation of key transistor parameters, including drain current, transconductance, transient times, etc .
Abstract Although there are already many efforts to investigate the electronic structures of twisted bilayer graphene, a definitive conclusion has not yet been reached. In particular, it is still controversial issue whether tunable electrical (or transport) bandgap exists in graphene film until now. Herein, for first time, demonstrated that can be opened by combination effect twist and vertical fields. addition, we have also developed facile chemical vapor deposition method synthesize...
A compact fiber-optic Fabry-Perot interferometric (FFPI) volatile organic compounds (VOCs) sensor is fabricated based on a single mode fiber (SMF) and polymethyl methacrylate (PMMA) film. The VOCs induce the swelling effect refractive index changes of PMMA film affects cavity length interferometer resulting in shift resonant dip, while change influences reflection extinction ratio (ER). sensitivities 2.7 pm/ppm for ethanol 2.17 acetone are achieved. Moreover, this insensitive to inorganic...
