How to improve the corrosion resistance and icing-delay ability of metal in practice is still a big challenge. Herein, a ZnO surface with superhydrophobicity was fabricated by combining anodic oxidation and surface modification on zinc substrate. The effects of topographies and chemical composition on surface wettability were discussed in detail. T...

Flexible pressure sensors have attracted great attentions in recent years. In this work, an innovative piezoresistive pressure sensor was prepared using a flexible composite film by dip-coating a self-made PVA-CNTs (polyvinyl alcohol-carbon nanotubes) slurry on a layer of electrospun PVDF (polyvinylidene fluoride) fibrous network. A set of flexible...

Printed circuit board (PCB) fabrication technology has been widely used in metasurfaces in microwave domain. However, such technology still needs a non-negligible fabricating period and cost. To further explore the ultra-low-cost, convenient processing and fast demonstrating method, we present a metasurface using silver ink to produce the digital p...

The influence of the laser fluence on the quality of percussion-drilled holes was investigated both experimentally and by an analytical model. The study reveals that the edge quality of the drilled microholes depends on the laser fluence reaching the rear exit of the hole and changes with the number of pulses applied after breakthrough. The minimum...

Resistive switching memory or memristors have been extensively studied worldwide, driven by perspective applications in nonvolatile memory, processing-in-memory, and neuromorphic computing hardware. Binary oxides are the most prevalent memristive materials; however, non-oxide materials can also exhibit resistive switching. In this study, ternary ni...
