Dynamic modeling and real-time risk assessment of tunnel fires using pressure-state-response (PSR)-enhanced bayesian network

Results in Engineering
Tunnel fires present complex and evolving scenarios owing to confined geometries, limited ventilation, and high traffic density; this often results in severe casualties and significant economic losses.

Unveiling the High‐Voltage Reactivity and Gas Evolution With Aluminum‐Based Chloride and Oxychloride Catholytes in Solid‐State Sodium Batteries

Advanced Energy Materials, EarlyView.
The work examines the electrochemical and interfacial behaviors of crystalline NaAlCl4 and amorphous Na–Al–oxychloride solid electrolytes with NaNi0.5Mn0.5O2 cathodes. Operando gas evolution and ToF‐SIMS analyses highlight that pure chloride solid electrolytes offer greater interfacial stability and safety compared to the oxychloride solid electrolytes

Farmers’ Protests in Germany: Media Coverage and Types of Bias

Agribusiness, EarlyView.
ABSTRACT The German farmers’ protests of 2024 sparked widespread media coverage and public debate. Yet, media coverage was not always positive, reflecting the media's attention‐seeking and selective focus. Occurrences of farmers blocking media outlets reflected distrust in how their concerns were portrayed.
