A Novel Crawling Robot Based on the Hexagonal Mesh Structure and Enhanced PID Control Strategy

Journal of Field Robotics, EarlyView.
ABSTRACT The locomotion of crawling robots is similar to that of caterpillars, relying on foot adhesion and body contraction to ensure flexible movement without compromising stability. However, most existing pneumatic soft crawling robots are incapable of simultaneously achieving forward, backward, turning, and climbing capabilities.

When should firms watch for cross‐industry competition? A demand‐side perspective

Strategic Management Journal, EarlyView.
Abstract Research Summary Research on competitor identification has primarily focused on intra‐industry competition. However, cross‐industry competitive threats are prevalent and consequential. We adopt a consumer‐oriented perspective to examine how consumer perceptions shape de facto competition across industry boundaries.

160 GHz Schottky Diodes from Solution‐Processed IGZO

Small, EarlyView.
A simple, scalable method for contact engineering of planar asymmetric nanogap electrodes enables the development of Schottky diodes with a cut‐off frequency of 160 GHz. Applying these diodes to radio‐frequency rectifying circuits yields output voltages in the range of 0.3–0.74 volts.

Engineering Hierarchically Nano‐Structured Cu Foams: Dynamic Hydrogen Bubble Templated Binder‐Free Freestanding Electrodes for Energy Applications

Small, EarlyView.
The competition between H2 evolution (HER) and Cu electrodeposition during the dynamic hydrogen bubble templating (DHBT) crucially influences the synthesized foam morphology. Generally, when HER is dominating, numerous small H2 bubbles form, resulting in compact Cu foams.
