Surface Science Insight Note: A Good Figure‐Of‐Merit Does Not Necessarily Yield Accurate Chemical Composition: Outcome of Mixed‐Metal Sulfate XPS Data Peak Fitting Using Nonlinear Least‐Squares Fitting of Peak Models

open access: yesSurface and Interface Analysis, EarlyView.
ABSTRACT The use of peak models and nonlinear least squares optimization, when applied to highly correlated signals without proper context, is shown to be inadequate for chemical state analysis. However, the use of peak models with physically motivated constraints and sufficient contextual information permits fitting of such models to spectra by ...

Influence of Temperature on the Reliability of Graphene‐Based Ozone Sensors

open access: yesSmall, EarlyView.
The reliability and stability of inkjet‐printed graphene flake sensors are evaluated. Stress assessments take place in ozone‐rich environments and at elevated temperatures, with the observation of a change in resistance. Surface‐sensitive techniques serve to investigate the failure and degradation mechanisms of printed graphene.

Potential‐Dependent Reversible Restructuring of Pt–Au Alloy Electrocatalysts

open access: yesSmall, EarlyView.
Using electrochemical X‐ray photoelectron spectroscopy (XPS), we show that Pt–Au alloys adjust their surface elemental composition to the applied electrochemical conditions. The surface dynamics are found to be highly reversible, even at room temperature, suggesting that dynamic restructuring of alloy nanoparticles occurs in a wide range of conditions,

Lithium Difluorophosphate and Fluoroethylene Carbonate Containing Electrolytes: How Instrumental Analytics Helps to Understand Synergistic Effects on Performance Improvement in High‐Voltage Li Battery Applications

open access: yesSmall Methods, EarlyView.
In this study, electrolyte investigations in cells for high‐voltage applications are carried out. The electrolytes contain varying contents of FEC and EC, including the replacement of EC by FEC and the addition of the electrolyte additive DFP. ABSTRACT Sequential improvement of lithium‐ion batteries is an ongoing process that addresses operational ...

Multi‐level fatigue reliability assessment of reinforced concrete railway bridges

open access: yesStructural Concrete, EarlyView.
Abstract This paper presents a multi‐level reliability framework for assessing the fatigue life of reinforced concrete (RC) railway trough bridges subjected to cyclic loading. The framework incorporates increasing levels of analytical complexity and real‐world data in four steps. First, an analytical model applies S–N curves and the Palmgren–Miner rule
