Degradation Mechanisms in PEM Water Electrolysis: Diagnosis and Impact
Advanced Materials Technologies, EarlyView.This review provides an analysis of degradation mechanisms in proton electrolyte membrane water electrolyzers (PEMWE), focusing on all key components. It discusses diagnostic and measurement techniques for evaluating degradation, less‐studied mechanisms, and an expert survey.

Too Few Cooks Spoil the Broth: Division of Labour and Directed Production [PDF]
How can a manager influence workers' activity while knowing little about it? This paper examines a situation where production requires several tasks, and the manager wants to direct production to achieve a preferred allocation of effort across tasks ...

Advanced Materials Technologies, EarlyView.An automation interface for environmental scanning electron microscopy (ESEM) enables simultaneous, interlaced data sets via frame‐by‐frame parameter changes. Demonstrated on oscillatory hydrogen oxidation over cobalt (Co) foil, dual‐magnification imaging bridges mesoscopic to microscopic length scales, capturing alternating views of surface dynamics ...

Multivariate Fractionally Integrated APARCH Modeling of Stock Market Volatility: A multi-country study [PDF]
Tse (1998) proposes a model which combines the fractionally integrated GARCH formulation of Baillie, Bollerslev and Mikkelsen (1996) with the asymmetric power ARCH speci¯cation of Ding, Granger and Engle (1993). This paper analyzes the applicability of a

A Soft Robotic Fish With a Dielectric Elastomer Actuator Body and Negative Stiffness Spine
Advanced Robotics Research, EarlyView.This work introduces a bio‐mimetic soft robotic fish driven by fiber‐reinforced dielectric elastomer actuators integrated as its body. By prestretching this active skin against a flexible spine, a negative stiffness system is created, enabling large‐amplitude bending.

Three-dimensional view of ultrafast dynamics in photoexcited bacteriorhodopsin
Nature Communications, 2019 Bacteriorhodopsin (bR) is a light-driven proton pump. Here the authors combine time-resolved crystallography at a free-electron laser, ultrafast spectroscopy and quantum chemistry to study the structural changes following multiphoton photoexcitation of ...

How Delegation Improves Commitment [PDF]
We often use delegation as a commitment device if a government faces problems of timeinconsistency. McCallum (1995, AER P&P) challenged this practice, claiming that delegation merely relocates the commitment problem but does not solve it.

3D‐Printing Aided Rapid Prototyping of Pretensioned Tensegrity Structures for Robotic Applications
Advanced Robotics Research, EarlyView.Printing, injection molding, and assembly (PMA) is a method for rapid prototyping mesoscale, topologically complex, and tensioned tensegrity structures. In combination with PMA method, two mold design strategies: modular mold and compact channel layout, enable efficiency and scalability for tensegrity fabrication.

Exports and Externalities: the other side of trade and ecological risk and Technology Diffusion in a Competitive World [PDF]
This paper develops a general equilibrium model to measure welfare effects of taxes for correcting environmental externalities caused by domestic trade, focusing on exter- nalities that arise through exports. Externalities from exports come from a number
