Predicting the Energy Spectra of Solar Energetic Particles with a Machine Learning Regression Algorithm

The Astrophysical Journal Letters
Solar energetic particles (SEPs) are a major source of space radiation, especially within the inner heliosphere. These particles, originating from solar flares and coronal mass ejections (CMEs), propagate primarily along interplanetary magnetic fields ...

Decoupling Activation and Preservation: Architectural Design Principles of Organic Frameworks for Selective Photocatalytic Methane Oxidation

Advanced Materials, EarlyView.
Selective methane (CH4) photooxidation emerges from architectural decoupling of activation and preservation. Programmable organic semiconductor frameworks spatially organize oxidative flux and intermediate residence, separating reaction zones from product domains to synchronize activation strength with stabilization and establish a selective oxidation ...

The 2024 July 23 Event: A Case Study of a Multispacecraft, Fe-rich Solar Energetic Particle Event

The Astrophysical Journal
Occasionally, solar energetic particle (SEP) events associated with fast, wide coronal mass ejections (CMEs) driving interplanetary shocks exhibit Fe/O abundance ratios that are significantly higher than the nominal value of 0.134.

Solvent‐Guided Chiral Assemblies and Chemical Doping of OEG‐Functionalized Conjugated Polymers

Advanced Materials, EarlyView.
Solvent‐dependent aggregation pathways dictate whether conjugated polymers form chiral lyotropic liquid‐crystalline assemblies or achiral packed aggregates. Mapping solvent‐controlled β₁ and β2 states reveals that weaker backbone association favors β₁ aggregates and reorganizable twisted mesophases, whereas stronger backbone association favors β2 ...

Backscattering Characteristics and the Underlying Mechanism of Lunar Soil at the Chang’e-6 Landing Site: Insight from In Situ Spectroscopy Analyses

The Astronomical Journal
The Chang’e-6 (CE-6) mission returned a lunar sample from the farside of the Moon for the first time. The Lunar Mineral Spectrometer (LMS) onboard the CE-6 Lander successfully acquired in situ multiangle spectral data of the sampling area, providing a ...

Review of solar energetic particle models

, 2023
Solar Energetic Particle (SEP) events are interesting from a scientific perspective as they are the product of a broad set of physical processes from the corona out through the extent of the heliosphere, and provide insight into processes of particle acceleration and transport that are widely applicable in astrophysics. From the operations perspective,
