Nanoscale Mechanisms of Corrosion Threshold: Effects of Passivation Film Crystal Structures

Abstract The corrosion resistance of passive films on reinforcing steel is fundamentally governed by the depassivation stability of iron oxide polymorphs under chloride-containing environments. In this study, the electrochemical behavior and atomistic depassivation mechanisms of...

On the Modular Platoon-based Vehicle-to-Vehicle Electric Charging Problem

This study introduces an innovative dynamic charging solution, defined as a platoon-based vehicle-to-vehicle charging (PV2VC). technology. A fleet of electricity suppliers (ESs) can be deployed to transfer power to other electric vehicles, defined as electricity requests (ERs), w...

Proactive traffic conflict prediction: uncovering multi-dimensional risk mechanisms through spatiotemporal heterogeneity

Objective Proactive traffic conflict prediction often relies on average-state macroscopic variables (e.g., mean speed, flow, density), which can obscure the underlying traffic flow instability and microscopic heterogeneity that precipitate critical interactions. The objective of...
