Characterizing the Radiative–Convective Structure of Dense Rocky Planet Atmospheres

open access: yesThe Planetary Science Journal
We use a one-dimensional line-by-line radiative–convective model to simulate hot, dense terrestrial-planet atmospheres. We find that strong shortwave absorption by H _2 O and CO _2 inhibits near-surface convection, reducing surface temperatures by up to ∼

Highly Conductive Liquid Metal Emulsion Gels for Three‐Dimensionally Printed Stretchable Electronics

open access: yesAdvanced Science, EarlyView.
This study presents a scalable two‐step method to create liquid metal emulsion gels suitable for 3D printing. The emulsion gel contains densely packed microcapsules within polymer matrices, resulting in minimal shrinkage and optimal printability. Printed features achieve excellent conductivity and ultrahigh deformability after mechanical activation ...

A Dormant Captured Oort Cloud Comet Awakens: (18916) 2000 OG44

open access: yesThe Astrophysical Journal Letters
We report the discovery of activity emanating from (18916) 2000 OG _44 (alternately designated 1977 SD), a minor planet previously reported to be both an extinct comet and an asteroid on a cometary orbit. We observed 2000 OG _44 with a thin tail oriented
