Anode‐Free Sodium Metal Batteries: From Materials Design to System‐Level Integration

Advanced Science, EarlyView.
Anode‐free sodium metal batteries hold no sodium reserve, so every inefficiency becomes permanent loss. Resolving the inventory into reversible, dead, and chemically bound fractions exposes what Coulombic efficiency hides. Practical 500‐cycle operation requires above 99.95%, a threshold few systems meet under lean electrolyte and high areal capacity ...

Passenger evacuation simulation considering the heeling angle change during sinking

International Journal of Naval Architecture and Ocean Engineering, 2019
In order to simulate the evacuation simulation of a ship during a sinking, the slope angle change of the ship must be reflected during the simulation. In this study, the passenger evacuation simulation is implemented by continuously applying the heeling ...

Nonlinear Ion‐Specific Control of Underwater Adhesion by Bottlebrush Polymer Interfaces

Advanced Science, EarlyView.
The efficiency of underwater adhesion is modulated by ion‐specific effects. Strongly hydrated Na+ remains separated from the mica surface by its hydration shell, preserving access to binding sites, whereas weakly hydrated K+ can partially dehydrate and occupy ditrigonal cavities.

Modeling Ultra-High-Density Exposure and Evacuation Dynamics in a High-Density Urban Plaza: An Agent-Based Simulation Study of Guangzhou Huacheng Plaza

Buildings
High-density urban plazas hosting multi-session public events often experience pulsed inflows, prolonged crowd retention, and localized bottleneck congestion, creating crowd-safety risks that cannot be fully captured by static capacity or total ...

Enhancing Specific Stiffness of Nano‐Architected Materials Through Generative AI and Active Learning

Advanced Science, EarlyView.
A structure‐centric generative framework searches voxelated design space directly, coupling a variational autoencoder with multi‐objective optimization and active learning to progressively expand the validated design domain. The discovered nano‐architectures, realized as pyrolytic carbon by two‐photon lithography, deliver 18–23% higher stiffness and 26–

A heterogeneous crowd evacuation model integrating multi-dimensional panic emotion characteristics

Journal of Physics: Complexity
In emergency evacuation scenes, environmental uncertainties and information deficits often trigger panic among individuals, which in turn impairs their ability to make sound judgments and decisions.
