Advanced Energy Materials, EarlyView.This review provides a bottom‐up evaluation of sodium‐ion battery safety, linking material degradation mechanisms, cell engineering parameters, and module/pack assembly. It emphasizes that understanding intrinsic material stability and establishing coordinated engineering control across hierarchical levels are vital for preventing degradation coupling ...

Properties of Kilonovae from Dynamical and Post-merger Ejecta of Neutron Star Mergers [PDF]
, 2017 Ejected material from neutron star mergers gives rise to electromagnetic emission powered by radioactive decays of r-process nuclei, the so-called kilonova or macronova.

Actinide Production in the Neutron-rich Ejecta of a Neutron Star Merger [PDF]
Astrophysical Journal, 2018 The rapid neutron-capture (“r-”) process is responsible for synthesizing many of the heavy elements observed in both the solar system and Galactic metal-poor halo stars.

High‐Fidelity Cretaceous‐Paleogene Boundary Investigations: Records of Impact and Transport
Geochemistry, Geophysics, GeosystemsThe Chicxulub impact on the Yucatán Peninsula triggered the end‐Cretaceous mass extinction 66 million years ago, but physical models still struggle to accurately describe ejecta generation and transport from this and other large meteorite impacts.

ALMA Observations of the DART Impact: Characterizing the Ejecta at Submillimeter Wavelengths
The Planetary Science Journal, 2023 We report observations of the Didymos–Dimorphos binary asteroid system using the Atacama Large Millimeter/submillimeter Array (ALMA) and the Atacama Compact Array (ACA) in support of the Double Asteroid Redirection Test mission.

Unveiling Localized Heat in Lithium‐Ion Cells for Intelligent Temperature Sensing
Advanced Energy and Sustainability Research, EarlyView.Heat generation, thermal responses, and intelligent management in batteries. Lithium‐ion batteries (LIBs) power electric vehicles, portable electronics, and grid‐scale storage, yet their safety, performance, and lifetime are constrained by thermal effects.

Impact of ejecta morphology and composition on the electromagnetic signatures of neutron star mergers [PDF]
, 2017 The electromagnetic transients accompanying compact binary mergers (gamma-ray bursts, after-glows and 'macronovae') are crucial to pinpoint the sky location of gravitational wave sources.

Supernova Ejecta Interacting with a Circumstellar Disk. I. Two-dimensional Radiation-hydrodynamic Simulations [PDF]
Astrophysical Journal, 2019 We perform a series of two-dimensional radiation-hydrodynamic simulations of the collision between supernova ejecta and circumstellar media (CSMs). The hydrodynamic interaction of a fast flow and the surrounding media efficiently dissipates the kinetic ...
