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.

Kpi form factors and final state interactions in D+ --> K- pi+ pi+ decays
, 2009 We present a model for the decay D+ --> K- pi+ pi+. The weak interaction part of this reaction is described using the effective weak Hamiltonian in the factorisation approach.

Stringent constraints on the scalar K pi form factor from analyticity, unitarity and low-energy theorems [PDF]
, 2010 We investigate the scalar K pi form factor at low energies by the method of unitarity bounds adapted so as to include information on the phase and modulus along the elastic region of the unitarity cut.

A Perspective on the Applications of Triphasic Gas Storage in Electrochemical Systems
Advanced Science, EarlyView.Gas storage in microporous materials positioned locally at an electrode or electrocatalyst surface enhances electrochemical processes. Abstract Microporous materials store gases under dry conditions (e.g., hydrogen or oxygen via physisorption), but in some cases microporous materials also show triphasic (e.g., in a solid|gas|liquid system) gas storage ...

BOUNDARY PROBLEM SOLUTION FOR EIGENMODES IN COAXIAL QUAD-RIDGED WAVEGUIDES
Information and Telecommunication Sciences, 2014 The boundary problem for eigenmodes in coaxial quad-ridged waveguides has been solved by the transverse field-matching technique. The formulas obtained provide possibilities to calculate cutoff wave numbers and electric and magnetic fields distributions ...

Advanced Energy Materials, EarlyView.This study investigates the feasibility of scaling up Prussian White (PW)‐based cathode manufacturing at a pilot scale. Through careful PW dehydration combined with optimized aqueous processing, we report the stepwise development of industrially relevant 1 Ah pouch cells and evaluate their performance under various conditions.

Improving the Kpi vector form factor through Kl3 constraints [PDF]
, 2010 The $K\pi$ vector form factor, $F_+^{K\pi}$, used to reproduce the Belle spectrum of $\tauKpi$ decays is described by means of a three-times subtracted dispersion relation also incorporating constraints from $K_{l3}$ decays.
