The Atomic Gas Properties of Green Pea Galaxies: Connections to Lyman Continuum Leakage

open access: yesThe Astrophysical Journal Letters
We have used the Green Bank Telescope to search for H i 21 cm emission from 30 Green Pea galaxies (GPs) at z  ≈ 0.012–0.045, obtaining 7 detections of H i 21 cm emission and 17 upper limits on the H i mass.

Surface‐Bound Superoxide Radical‐Mediated Photo‐Fenton Mineralization of Ciprofloxacin on Fe‐Sillenite Nanosheets

open access: yesAdvanced Science, Volume 13, Issue 29, 22 May 2026.
This study systematically compares the degradation efficiency of CIP in a H2O2‐alone system and a novel Bi12FeO20‐H2O2 photo‐Fenton system. It reveals for the first time the presence of a quinone‐imine intermediate in the H2O2‐alone system, which exhibits toxicity comparable to CIP.

Atomically Revealing Bulk Point Defect Dynamics in Hydrogen‐Driven γ‐Fe2O3 → Fe3O4 → FeO Transformation

open access: yesAdvanced Functional Materials, Volume 36, Issue 20, 9 March 2026.
In situ TEM uncovers the atomic‐scale mechanisms underlying hydrogen‐driven γ‐Fe2O3→Fe3O4→FeO reduction. In γ‐Fe2O3, oxygen vacancies cluster around intrinsic Fe vacancies, leading to nanopore formation, whereas in Fe3O4, vacancy aggregation is suppressed, preserving a dense structure.
