Live Imaging of Silver Nanostructures Electrochemically Dissolving at Open‐Circuit Potential

open access: yesSmall, EarlyView.
Stability of electrocatalysts as used in energy conversion systems is pivotal for sustainable technologies, yet degradation dynamics at the nanoscale remain elusive. Harnessing beam‐effect corrected electrochemical liquid phase electron microscopy combined with correlative bulk‐scale electrochemical testing reveals silver corrosion on platinum under ...

Additives for Aluminum‐Air Batteries: A Review

open access: yesSmall, EarlyView.
The role of electrolyte additives in Al–air batteries is investigated by focusing on their capacity to moderate Al corrosion rates, inhibit self‐discharge, and prevent surface barrier formation. Additives present in organic, inorganic, and hybrid categories, which regulate the Al–electrolyte interface by forming protective films on the Al surface ...

Multimetal Doping and Heterostructure Engineering of RuO2 for Durable and Efficient Oxygen Evolution

open access: yesSmall Science, EarlyView.
A MnCoNi–RuO2 heterostructure engineered through multimetal doping and mixed‐oxide interface formation generates lattice distortion, oxygen vacancies, and electronically optimized active sites for the oxygen evolution reaction. MnCoNi–RuO2 achieves high activity and durability across alkaline and acidic media, sustaining 100 h (AEMWE) anion exchange ...

Unveiling Regional Disparities: Exploring Cybersecurity Capabilities and Performance Through Systems Theory Approach

open access: yesSystems Research and Behavioral Science, EarlyView.
ABSTRACT This study investigates the relationship between cybersecurity capabilities (CCs) and cybersecurity performance (CP) across diverse regional contexts, employing ordinary least squares (OLS) and random forest (RF) regression models. The research highlights how economic, political and cultural factors shape CCs and their impact on CP ...

Comparison of Intergranular Corrosion Resistance and Hardness between Nitrogen and Carbon Martensites in Stainless Steels

open access: yessteel research international, EarlyView.
By applying solution heat treatment after plasma nitriding, followed by requenching and tempering, researchers successfully obtained nitrogen‐rich martensite on AISI 409. This study compares the intergranular corrosion resistance and hardness of nitrogen‐rich martensite in AISI 409 with carbon‐rich martensite in AISI 420.
