Filamentary Dust Polarization and the Morphology of Neutral Hydrogen Structures
The Astrophysical JournalFilamentary structures in neutral hydrogen (H i ) emission are well aligned with the interstellar magnetic field, so H i emission morphology can be used to construct templates that strongly correlate with measurements of polarized thermal dust emission ...

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.The engineered IrOx/FeEu‐NiTex composite, with ultralow Eu (0.72 at%) and Ir (0.14 at%) content, harnesses an asymmetric dual‐electron‐bridge structure (Ni 3d–O 2p–Eu 4f, Ni 3d–O 2p–Ir 5d) for gradient orbital coupling. This unique architecture delivers superior and robust alkaline oxygen evolution activity, enabling efficient low‐iridium water ...

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.In this work, a novel biomolecule/semiconductor hybrid catalyst was prepared by loading anthraquinone‐liked juglone onto anatase TiO2. This catalyst exhibited high photocatalytic activity for H2O2 production. Hydrogen peroxide (H2O2) is a vital oxidant with broad industrial applications, and its production via photocatalysis represents a highly ...
