Progress in Experimental Methods Using Model Electrodes for the Development of Noble‐Metal‐Based Oxygen Electrocatalysts in Fuel Cells and Water Electrolyzers

open access: yesSmall Methods, EarlyView.
Electrochemical experimental studies using single‐crystal electrodes as model catalysts, with controlled elemental distribution, microstructure, and modification patterns, provide valuable insights into reaction and degradation mechanisms as well as catalyst development strategies.

Probabilistic analysis of crack widths associated with quality control procedures

open access: yesStructural Concrete, EarlyView.
Abstract Existing concrete specifications limit the crack width in order to fulfill the limits of serviceability and durability. The crack width calculation results differ depending on the influences of the variability of the used materials, the geometry, the actions and the uncertainty of the used calculation model itself.

Inter‐Rater Disagreements in Applying the Montreal Classification for Crohn's Disease: The Five‐Nations Survey Study

open access: yesUnited European Gastroenterology Journal, EarlyView.
ABSTRACT Background The Montreal classification has been widely used in Crohn's disease since 2005 to categorize patients by the age of onset (A), disease location (L), behavior (B), and upper gastrointestinal tract and perianal involvement. With evolving management paradigms in Crohn's disease, we aimed to assess the performance of gastroenterologists
