External‐Field‐Enhanced Helmholtz‐Layer Local Charge Density Enables C─C Coupling in Pure‐H 2 O‐Fed CO 2 Electroreduction To C 2+ Products

ABSTRACT Electrochemical CO 2 reduction (ECO 2 R) is a promising decarbonization technology but is limited by the trade‐off between catalytic performance and system stability. Here, we present an external‐field‐assisted strategy to enhance the local charge density of the Helmholt...

Draft Tube Wake Vortex Evolution and Suppression in a Pump as Turbine with Splitter Blades Based on a Modified Burgers Vortex Model

Owing to its efficient energy recovery capability, the pump as turbine (PAT) has attracted considerable attention and has been widely applied in micro hydropower systems. However, under off-design conditions, large-scale helical vortex ropes are readily induced in the draft tube,...

Design and Validation of a Permanent Magnet Self-Locking Electromagnetic Balancing Device for Combine Harvester Threshing Drums

Imbalance-induced vibration of the threshing drum is a common problem during rice harvesting, especially when rice straw becomes entangled with the threshing components. In this study, a permanent magnet self-locking electromagnetic balancing device was designed for a combine har...
