Architected Spatially Deterministic Multiscale Phase Segregation in Block Copolymer Composites for Augmented Radiative Cooling

Advanced Science, EarlyView.
Multiscale phase segregation in block copolymers enables spatially deterministic structuring from molecular to macroscopic scales, decoupling solar scattering and infrared emission for augmented radiative cooling. ABSTRACT Passive radiative cooling, which reflects solar irradiation while emitting heat through the atmospheric window, provides a ...

Total Solar Eclipse White-light Images as a Benchmark for Potential Field Source Surface Coronal Magnetic Field Models: An In-depth Analysis over a Solar Cycle

The Astrophysical Journal
Potential field source surface (PFSS) models are widely used to simulate coronal magnetic fields. PFSS models use the observed photospheric magnetic field as the inner boundary condition and assume a perfectly radial field beyond a “source surface” ( R ...

Spin Splitting Coupled Visible‐Light Driven Injection Photocurrent in Bilayer Altermagnets

Advanced Science, EarlyView.
Interlayer engineering in bilayer altermagnets continuously tunes visible‐light injection photocurrents, accompanied by controllable altermagnetic spin splitting. Enhanced interlayer hybridization reconstructs the band and quantum geometries, leading to opposite evolution of the normal and magnetic injection currents and establishing a direct ...

Probing solar subsurface magnetic fields

, 2011
[[abstract]]Helioseismology uses solar p-mode oscillations to probe the structure of the solar interior. The modifications of p-mode properties due to the presence of solar magnetic fields provide information on the magnetic fields in the solar interior.

Multifunctional Ionic Liquid Enabling Cation Homogenization and Lead Chelation for Pure‐Iodide Wide‐Bandgap Perovskite Solar Cells

Advanced Science, EarlyView.
This work presents a multifunctional ionic liquid, [SO3H‐PMIm][OTf], that addresses A‐site cation inhomogeneity and lead toxicity in pure‐iodide wide‐bandgap perovskite solar cells. The additive enables homogeneous cation distribution, achieving 22.02% efficiency with 90% retention after 3000 h and reducing lead leakage by over 58%, thereby ...

Q‐LEAP: Millisecond Hyperdimensional Optimization for Full‐Spectrum Optical Metamaterials

Advanced Science, EarlyView.
Q‐LEAP integrates physics‐informed residual machine learning with factorization‐machine‐encoded quantum annealing to design full‐spectrum optical metamaterials. It explores a 2108 design space and, in a single 2.56 ms annealing step, reaches 85.83% of the theoretical FoM limit, enabling selective 5‐8 µm emission with 3–5 and 8–14 µm suppression and ∼40×

Long-term solar activity and its implications to the heliosphere, geomagnetic activity, and the Earth’s climate

Journal of Space Weather and Space Climate, 2013
The Sun’s long-term magnetic variability is the primary driver of space climate. This variability is manifested not only in the long-observed and dramatic change of magnetic fields on the solar surface, but also in the changing solar radiative output ...

SOLAR ERUPTION ON 4 JANUARY 2011: CASE STUDY FOR SPACE EARLY WARNING [PDF]

, 2011
We perform intuitive analysis for solar eruption on 4 January 2011. Since we do not have magnetic observational data from the eruption, we perform first order calculation and expands it as interplanetary total effect of energy propagation by retro ...
