The Impact of Catalyst Layer Composition and Structure on Performance and Durability of PEMWE Anodes

Advanced Materials Technologies, EarlyView.
This article explores a new type of anode for water electrolysis that uses less iridium, a rare and expensive metal. By combining stable iridium oxide with platinum and carbon‐based materials, the authors create a catalyst layer that maintains strong performance.

Essays on Sovereign Default

This dissertation consists of three chapters on sovereign default. Thematically, they are linked by their examination of how sovereign risk influences government policy, equilibrium allocations, and welfare. Chapter 1 investigates the optimal currency denomination in sovereign bonds. Chapter 2 and 3 delve into self-fulfilling debt crises.

Characterization of Droplet Formation in Ultrasonic Spray Coating: Influence of Ink Formulation Using Phase Doppler Anemometry and Machine Learning

Advanced Materials Technologies, EarlyView.
This study explores how machine learning models, trained on small experimental datasets obtained via Phase Doppler Anemometry (PDA), can accurately predict droplet size (D32) in ultrasonic spray coating (USSC). By capturing the influence of ink complexity (solvent, polymer, nanoparticles), power, and flow rate, the model enables precise droplet control

Terahertz Waveform‐Selective Antenna Using a Patch Structure Loaded with Nonlinear Circuits

Advanced Photonics Research, EarlyView.
A waveform‐selective antenna that integrates the functions of waveform selectivity, electromagnetic shielding, and EM wave radiation has been proposed. By integrating different nonlinear circuits and selecting appropriate component values, the antenna can achieve high reflection of either a pulse wave or a continuous wave, while allowing the other ...

Sovereign Default Risk Premia, Fiscal Limits and Fiscal Policy [PDF]

We develop a closed economy model in order to study the interactions among sovereign risk premia, fiscal limits and fiscal policy. The stochastic fiscal limit, which measures the ability and willingness of the government to service its debt, arises ...

Multiobjective Codesign Optimization of a Planar Pneumatic Artificial Muscle‐Based Snake‐Like Robot for Enhanced Agility and Energy Efficiency

Advanced Robotics Research, EarlyView.
A codesign multiobjective optimization framework was developed to enhance the morphology and controller of a snake‐like robot driven by artificial muscles. It improved planar locomotion, agility, and power efficiency. The approach optimized link geometry and controller gains, revealing that shorter muscles near joints and longer linkages maximize ...
