Breaking the Durability–Power Trade‐Off: Boron‐Directed Faceted O3 Cathodes for High‐Rate Sodium‐Ion Batteries

Advanced Energy Materials, EarlyView.
Boron‐oxide‐assisted particle engineering stabilizes O3‐type layered cathodes for sodium‐ion batteries by mitigating phase transitions and lattice strain. Acting as flux and structural modifier, boron forms submicron hexagonal platelets with (003) facets and expanded Na‐layer spacing, enabling rapid Na⁺ diffusion and mechanical resilience.

Chemical Abundances Shape History (CASH). I. A Link between Giant Planets' Orbital Periods and Host Stellar C/O Ratios

The Astronomical Journal
The chemical abundance of host stars plays a pivotal role in shaping the formation history of planetary systems, yet the influence of elements beyond iron remains poorly understood. Here, we investigate the relationship between the carbon-to-oxygen (C/O)

Decoupling Chemical and Mechanical Contributions to Capacity Fading in Ni‐Rich Cathodes for Sulfide‐Based All‐Solid‐State Batteries

Advanced Energy Materials, EarlyView.
Ni‐rich cathodes in sulfide‐based ASSBs undergo intertwined (electro)chemical and mechanical degradation. Here, a new diagnostic framework is presented to decouple each contribution by partitioning capacity fading into charge and discharge fading.

Oxygen‐Driven Structural Reorganization by Trace Water Enabling Fast Li‐Ion Transport in a Pliable Solid Electrolyte

Advanced Energy Materials, EarlyView.
Trace water is acting as a constructive mediator in 2LiCl–GaF3, markedly increasing ionic conductivity while reorganizing local coordination. Hydration creates localized Li+ solvation environments and partially dissociates ion pairs, enhancing Li‐ion mobility.

Solar System Migration Points to a Renewed Concept: Galactic Habitable Orbits

The Astrophysical Journal Letters
Astrophysical evidence suggests that the Sun was born near 5 kpc from the Galactic center, within the corotation radius of the Galactic bar, around 6–7 kpc.

Internal Electric Field‐Guided, Low‐Adsorption Ferroelectric Anode Protective Layers for Sustainable Suppression of Polysulfide Side Reactions in Lithium–Sulfur Batteries

Advanced Energy Materials, EarlyView.
A positively polarized ferroelectric β‐pvdf layer incorporating fluorinated boron nitride nanosheets (PPFBN) establishes a strong internal field that promotes Li+ transport toward the anode while suppressing the migration of polysulfide anions. In addition, its intrinsically low polysulfide affinity helps preserve protective‐layer functionality ...

A break in planet occurrence near the pebble isolation mass should be observable by the Roman microlensing survey

Astronomy & Astrophysics
Microlensing detections are uniquely well suited to probing the population of planets outside the water ice line, down to planetary masses comparable to the Earth’s. We performed 1D pebble-accretion population synthesis simulations to explore a sample of

Joule self‐heating enabled oxygen transport and coupled methane reactions in a La0.6Sr0.4Co0.2Fe0.8O3‐δ hollow fiber membrane reactor

AIChE Journal, EarlyView.
Abstract Mixed‐conducting ceramic hollow fiber membranes are a versatile platform for oxygen separation, value‐added chemical production, and oxy‐combustion. Because oxygen permeation is thermally activated, these systems typically rely on bulky, energy‐intensive furnaces that suffer from low efficiency and large thermal inertia.

Twinkle Twinkle Little Star, Roman Sees Where You Are: Predicting Exoplanet Transit Yields in the Rosette Nebula with the Nancy Grace Roman Space Telescope

The Astronomical Journal
Young stars host only a small fraction of the known exoplanet population because their photometric variability, magnetic activity, and frequent placement in dense, poorly resolved regions hamper exoplanet detections.
