The Bright Rim Prominences according to 2.5D Radiative Transfer

The Astrophysical Journal Letters
Solar prominences observed close to the limb commonly include a bright feature that, from the perspective of the observer, runs along the interface between itself and the underlying chromosphere. Despite several idealized models being proposed to explain

Cross‐scale Material‐Structure Synergy for 2D Metamaterials: Toward Customizable Intelligent Electromagnetic Manipulation in Multiphysics Fields

Advanced Science, EarlyView.
Recent advances in metasurface‐enabled low‐observable technologies are reviewed from the perspective of cross‐scale material–structure synergy. Electromagnetic, thermal, optical, and acoustic stealth are highlighted together with dynamic tuning, programmable coding, data‐driven inverse design, artificial intelligence, multispectral compatibility, and ...

DIP-Like Magnetic Structure Seen in Solar Prominences

, 2002
Solar prominences are relatively dense objects suspended in the hot and tenuous solar corona. It has long been speculated that prominence material is supported against gravity by the Lorentz force exerted by magnetic field whose line of force is locally ...

Grain‐Boundary‐Enriched Cocatalyst Coupled With CuSCN Hole Transport Layer for Efficient Solar Water Oxidation in BiVO4 Photoanode

Advanced Science, EarlyView.
A grain‐boundary‐enriched NiFe cocatalyst is coupled with a CuSCN hole transport layer on BiVO4 photoanodes. The integrated architecture promotes hole extraction, interfacial charge transfer, and surface OER kinetics, highlighting cocatalyst microstructure regulation as a complementary strategy to hole transport layer engineering. ABSTRACT Solar‐driven

Magnetogram-matching Biot–Savart Law and Decomposition of Vector Magnetograms

The Astrophysical Journal
We generalize a magnetogram-matching Biot–Savart law (BS l ) from planar to spherical geometry. For a given coronal current density J , this law determines the magnetic field $\widetilde{{\boldsymbol{B}}}$ whose radial component vanishes at the surface ...

Self‐Healing Ionogel Dual‐Network Enables Synergistic Defect Passivation and Strain Relief for High‐Efficiency Robust Perovskite Photovoltaics

Advanced Science, EarlyView.
PSCs are afflicted by inherent defects and lattice strain that limit PCE and stability. A cross‐linked multifunctional ionogel [HA‐AA][EMIES] is developed to modulate crystallization, relieve residual strain, and passivate defects, extending carrier diffusion length to over 8 µm and delivering PCEs of 26.45% for rigid devices and 25.14% for flexible ...

Thermal Shifts Dominate Single‐Gene Responses to Transcription‐Targeting Antibiotics

Advanced Science, EarlyView.
Thermal shifts reshape bacterial responses to transcription‐targeting antibiotics. In E. coli, temperature can dominate antibiotic‐induced genome‐wide expression, particularly outside 30°C–39°C, through changes in adenosine triphosphate (ATP), nucleoid organization, and drug‐target engagement.
