Role of Strategic Reasoning in Constitutional Interpretation: In Defense of the Pathological Perspective [PDF]

, 1986
A Wiener model consists of a linear dynamic block followed by with a nonlinear static block. When identifying the parameters of such a system, the Prediction Error Method (PEM) can be used.

Acoustic‐driven surface cleaning with millimeter‐sized bubbles at translational resonance

Droplet, EarlyView.
Time‐lapse visualization comparing bubble trajectories. The top panel (0 Hz) shows a bubble's linear path under no acoustic forcing, while the bottom panel (50 Hz) demonstrates the oscillatory motion induced by acoustic waves at a resonance mode. This mechanism holds promising potential for applications such as surface cleaning.

Achievement of Transition Metal Chalcogenides/Oxides in Hydrogen Production by Seawater Electrolysis

EcoEnergy, EarlyView.
Transition metal chalcogenides (TMCs)/oxides have shown great application potential in seawater splitting for hydrogen generation due to their adjustable electronic properties, abundant active sites, and excellent catalytic performance. ABSTRACT Under the impetus of global “dual carbon” goals, green hydrogen has become a key component of the future ...

Comprehensive Analysis of the Degradation Phenomena of Proton Exchange Membrane Water Electrolyzers with Iridium on Antimony Tin Oxide Anodes

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study examines the structural and chemical evolution of low‐loaded Ir/ATO anodes during PEM water electrolysis under realistic conditions. Iridium dissolution is largely suppressed. In the early stages, both ionomer and support degradation are detected. Morphological reorganization occurs at the interface between the anode catalyst layer (ACL) and

Ordered Nanostructural Engineering of Cathode Catalyst Layer With High Mass Transport Efficiency for High‐Performance Ultra‐Low Pt Loading Proton Exchange Membrane Fuel Cells

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
An ordered cathode catalyst layer with efficient mass transport capability was developed based on the ALD of Pt onto VACNTs for high‐performance ultra‐low Pt loading PEMFC. The order‐structured cathode catalyst layer (CCL) has been considered the most promising solution to construct low‐cost proton exchange membrane fuel cells (PEMFCs) with an ultra ...

Dual‐Functional Sulfonated Nanocellulose for Proton Exchange Membranes With High Proton Conductivity at Low Humidity

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A scalable dual‐functional strategy yields simultaneously sulfonated and nanosized cellulose for proton exchange membranes with continuous hydrogen‐bond networks. These sustainable membranes exhibit low‐humidity proton conductivity twofold higher than Nafion 212, providing a robust solution for next‐generation fuel cells.

Unveiling Anodic Reconstruction of Electroless‐Deposited Dual‐Sided NiFeP Catalyst‐Coated Membranes for Efficient Anion Exchange Membrane Water Electrolysis

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A rapid electroless deposition strategy enables the 15 min fabrication of dual‐sided NiFeP catalyst‐coated membranes (CCMs) for anion exchange membrane (AEM) water electrolysis. The resulting ionomer‐free CCMs offer strong membrane‐catalyst adhesion and efficient ionic transport.

Developing a Suitable Anion Exchange Layer Structure for Pure–Water Fed Bipolar Membrane CO2 Electrolysis

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A porous anion exchange layer (AEL) is implemented in a forward‐biased bipolar membrane CO2 electrolyzer to suppress carbonate crossover, support CO2 regeneration and maintain cathode alkalinity. Two fabrication strategies are compared—deposition on a silver gas diffusion electrode (GDE) or on the CEM—showing that a porous AEL‐coated GDE provides the ...
