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

Adiabatic DC-AC Power Converter with 99% Efficiency

, 2016
This paper describes a novel approach to building a high efficiency and dimensionally compact power converter / inverter. A prototype was built for the Google / IEEE Little Box competition. The converter takes a 400-450 V DC input and creates a single-phase 230V AC output. It is capable of supplying 2kW continuously to a load.
