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.

The Mass of Stirring Bodies in the AU Mic Debris Disk Inferred from Resolved Vertical Structure [PDF]
, 2019 The vertical distribution of dust in debris disks is sensitive to the number and size of large planetesimals dynamically stirring the disk, and is therefore well-suited for constraining the prevalence of otherwise unobservable Uranus and Neptune analogs.

Inferring Planet and Disk Parameters from Protoplanetary Disk Images Using a Variational Autoencoder
The Astrophysical JournalDust-continuum observations of many protoplanetary disks (PPDs) reveal rings and gaps that are widely interpreted as evidence of ongoing planet formation. Here we present the first framework for inferring planet and disk parameters from such images using

Advanced Energy Materials, EarlyView.This work reports 2D MXene‐derived TiN thin films with (111)‐preferred orientation for transparent Ta3N5 photoanodes, demonstrating effective electron transfer behavior. All‐nitride electron‐collection architecture based on MXene‐derived TiN and n‐GaN resolves a long‐standing materials bottleneck between photocarrier transport and light transmission in

Formation of super-Earths in a protoplanetary disk
, 2018 <p>This is a simulation of the process of formation for a planetary system with close-in super-Earths.</p> <p>The simulation begins with 125 planetary embryos, each with 0.4 times the mass of the Earth. The gray region shows the height

The Dynamical Interaction between Low-mass Planets and Dust Coagulation
The Astrophysical Journal LettersWe investigate the impact of a low-mass planet on dust coagulation, and its consequent feedback on planetary migration, using a linear analysis of the coupled dust–gas hydrodynamic equations.

Dynamics of the TWA 7 planetary system and possibility of an additional planet
Astronomy & AstrophysicsContext. The debris disk surrounding the young star TWA 7 exhibits morphological features that tightly constrain its planetary architecture. JWST/MIRI observations have recently revealed a directly imaged outer planet orbiting at a large separation.

Long-term Evolution of Warps in Debris Disks—Application to the Gyr-old System HD 202628
The Astrophysical Journal, 2023 We present the results of N -body simulations meant to reproduce the long-term effects of mutually inclined exoplanets on debris disks, using the HD 202628 system as a proxy.

Clade‐wide morphological and functional variation of the sauropsid columella
The Anatomical Record, EarlyView.Abstract The columella (=stapes) is the middle ear bone of reptiles that transmits vibrations from the environment to the inner ear. It has been shown to exhibit extensive interspecific morphological disparity in several clades; however, its morphological variation and associated functional consequences remain poorly described.

The Dependence of the Structure of Planet-opened Gaps in Protoplanetary Disks on Radiative Cooling
The Astrophysical JournalPlanets can excite density waves and open annular gas gaps in protoplanetary disks. The depth of gaps is influenced by the evolving angular momentum carried by density waves.
