Two Distinctly Different Characteristics of Flare-driven Coronal Rain Revealed from High-resolution Spectroscopic Imaging Observations with FISS/GST

The Astrophysical Journal
We report on a flare-driven coronal rain event observed along postflare loops during the decay phase of an X1.6-class solar flare. Although high-resolution studies of flare-driven coronal rain have been conducted, imaging spectroscopic studies are rare ...

Weaving Intelligence: Thermally Drawn Multimaterial Fibers Toward AI‐Enabled Smart Textiles

Advanced Materials, EarlyView.
Thermally drawn multimaterial fibers are rapidly advancing as intelligent structural units for next‐generation smart textiles. Integrating multimaterial architectures with neuromorphic and spiking‐neural‐network principles enables fabrics that can sense, compute, and adapt autonomously.

Variations in the solar constant due to solar active regions

The Astrophysical Journal, 1980
Solar activity is expected to affect the solar constant at some level. Recent observations and data analysis show the amount of variation to be expected for active regions, faculae, and sunspots on the apparent solar brightness. It is concluded that the maximum effect is about 20 times greater for sunspots than for faculae per unit area.

Acoustic imaging and subsurface structure of solar active regions

, 2011
[[abstract]]Using high spatial resolution helioseismic data taken with the TON (Taiwan Oscillation Network) instruments, we have developed a method, called “acoustic imaging”, to probe the structure and properties of solar active regions.

Linker‐Engineered Dimeric Acceptors Afford Efficient Organic Photocatalytic Hydrogen Evolution via Tailored Nanomorphology for Long‐Lived Charge Accumulation

Advanced Materials, EarlyView.
We developed a new series of monomeric (MY) and dimeric acceptors incorporating unfused (DY1) and fused (DY2) linkers, which establish a controlled self‐aggregation trend of MY > DY2 > DY1. The DY2‐based system yields a bulk‐heterojunction nanoparticle morphology that appears to balance phase separation and interfacial accessibility, consistent with ...
