Frequency Characteristic Analysis of the VSC-HVDC DC Oscillating Power under AC Sub-Synchronous Disturbances

The DC-side response characteristics of the VSC-HVDC transmission system under AC-side sub-synchronous disturbances may lead to the propagation of AC/DC oscillations, and then there may be non-fundamental frequency oscillation on the DC-side.

Internal Resonance Mismatch‐Controlled Dissipative Bistability Collapse in Coupled Micromechanical Oscillators

Advanced Science, EarlyView.
This paper reveals internal resonance mismatch‐controlled dissipative bistability collapse in a coupled micromechanical resonator. Tuning δIR changes both internal‐mode amplitude and phase‐dependent feedback. For negative mismatch, Duffing bistability survives.

Plasma‐Engineered Polyethylene‐Reinforced Anion Exchange Membranes With Low Ionic Resistance and Low Hydrogen Crossover for Water Electrolysis

Advanced Science, EarlyView.
Oxygen plasma functionalizes porous polyethylene, enabling complete hydrocarbon ionomer infiltration within a dense submicron pore network. The resulting reinforced composite membrane simultaneously enhances mechanical robustness and suppresses hydrogen permeation at ultrathin thickness. An integrated performance index confirms the effectiveness of the
