Scalable Crackle‐Lithography for Multifunctional Enclosed Plastic Nanofluidic Devices

open access: yesAdvanced Science, EarlyView.
Crackle‐lithography enables scalable fabrication of enclosed plastic‐substrate‐based nanofluidic devices with interconnected nanochannels that enable molecular transport, optical interrogation, confined electroless copper deposition, and ionic memristive behavior.

ALMA Reveals an Eccentricity Gradient in the Fomalhaut Debris Disk

open access: yesThe Astrophysical Journal
We present evidence of a negative eccentricity gradient in the debris disk of the nearby A-type main-sequence star, Fomalhaut. Fitting to the high-resolution, archival ALMA 1.32 mm continuum data for Fomalhaut (with a synthesized angular resolution of 0 $

The Influence of Cold Jupiters in the Formation of Close-in Planets. I. Planetesimal Transport

open access: yesThe Astrophysical Journal, 2023
The formation of a cold Jupiter (CJ) is expected to quench the influx of pebbles and the migration of cores interior to its orbit, thus limiting the efficiency of rocky planet formation either by pebble accretion and/or orbital migration.

Single‐Nucleus Atlas of Spinal Sarcopenia Patients Reveals Disruption of Quiescent and Regenerative Satellite Cell Niches in Fatty‐Infiltrated Muscle

open access: yesAdvanced Science, EarlyView.
Mechanisms of Fatty Infiltration and Muscle Degeneration. Clinical metadata identified intramuscular fat accumulation as an independent driver of muscle mass decline. Single‐nucleus RNA sequencing of spinal sarcopenia muscle revealed adipogenic reprogramming of fibro‐adipogenic progenitors, satellite‐cell niche disruption, and elevated levels of the ...

Pursuing the planet-debris disk connection: analysis of upper limits from the Anglo-Australian planet search

open access: yes, 2015
All rights reserved.Solid material in protoplanetary disks will suffer one of two fates after the epoch of planet formation; either being bound up into planetary bodies, or remaining in smaller planetesimals to be ground into dust.

Hybrid Metal–Organic Framework‐Derived Dual Active Site Catalysts Enabling Surface‐Enriched Cathode and Modified Zinc Anode for Long‐Life Zinc–Air Batteries

open access: yesAdvanced Science, EarlyView.
This work demonstrates the implementation of MOF‐assisted anode and cathode materials for prolonged cycling of zinc‐air batteries with strong redox capability and structural stability. ABSTRACT The surface modification of zinc anodes and the development of effective cathode dual‐functional oxygen electrocatalysts remain of paramount interest for ...

On the Orbital Evolution of Multiple Wide Super-Jupiters: How Disk Migration and Dispersal Shape the Stability of the PDS 70 System

open access: yesThe Astrophysical Journal
Direct imaging has revealed exoplanet systems hosting multiple wide-orbit Super-Jupiters, where planet–planet interactions can shape their long-term dynamical evolution.

Formation of cold giant planets around late M dwarfs via core accretion and the fate of inner rocky worlds

open access: yesAstronomy & Astrophysics
Context. Modeling how cold giant planets form around M dwarfs remains a challenge, both because their protoplanetary disks can lack sufficient mass and because such planets are expected to migrate inward while interacting with the disk.

Quantifying the Impact of the Dust Torque on the Migration of Low-mass Planets

open access: yesThe Astrophysical Journal, 2023
Disk solids are critical in many planet formation processes; however, their effect on planet migration remains largely unexplored. Here we assess this important issue for the first time by building on the systematic measurements of dust torques on an ...

The Planet-Disk Connection: from Protoplanetary Disks to Planetary Atmospheres [PDF]

open access: yes, 2022
When gas giant planets form, they influence the structure of the surrounding gas disk, which in turn shapes the final compositions of their gas envelopes.
