A Semiempirical Estimate of Solar Extreme-ultraviolet Evolution from 10 Myr to 10 Gyr

The Astronomical Journal
The extreme-ultraviolet (EUV; 100–911 Å) spectra of F, G, K, and M stars provide diagnostics of the stellar chromosphere through the corona, with line and continuum formation temperatures spanning roughly 10 ^4 –10 ^7 K.

Positional Isomer Engineering for Crystallization Kinetics Control in Wide‐Bandgap Perovskite Solar Cells

Carbon Energy, EarlyView.
Based on the ortho‐para configuration of the amino‐sulfonic acid group, 2,4‐diaminobenzenesulfonic acid (2,4‐DABSA) forms the strongest coordination with the perovskite precursor among its isomers, guiding a unique “fast nucleation followed by slow crystallization” kinetics.

Using the Cartwheel CME to Predict Off-limb Observations of CMEs for New and Upcoming UV and EUV Spectrometers

The Astrophysical Journal
Coronal mass ejections (CMEs) expel multithermal, magnetized plasma from the Sun, and when directed toward Earth, can cause extensive damage to space and ground-based electronics.

Impacts of Extreme Ultraviolet Late Phase of the Solar Flare on Ionospheric Electrodynamics

The Astrophysical Journal Letters
Previous investigations of ionospheric electrodynamical responses to solar flares primarily focused on the main phases (MPs) of solar flares. Typical solar irradiance models for driving global ionosphere models do not include the extreme ultraviolet (EUV)

Benzo[c][1,2,5]Thiadiazole Linkers Enhance the Effectiveness of Cavity‐Containing Supramolecular Photocatalysts

Chemistry – A European Journal, EarlyView.
Seven novel supramolecular photosensitizers based on benzo[c][1,2,5]thiadiazole (BTZ) tethered to calix[4]arene (C[4]) scaffolds are reported with facile, scalable, and selective syntheses. Their abilities to produce singlet oxygen have been tested through the photo‐oxidation of α‐terpinene.

Data-driven Simulation of Effects of a Solar Flare with Extreme-ultraviolet Late Phase on Ionospheric Electron Density

The Astrophysical Journal
Effects of the extreme-ultraviolet (EUV) late phase of solar flares on the ionosphere were rarely studied. Here we simulated such effects on the ionospheric electron density using an ionosphere−thermosphere coupled model driven by the realistic solar ...

Design of Solar Energy Harvesting Reactor From 2D to 3D Structures for Solar Thermal Conversion

Carbon Innovation, EarlyView.
ABSTRACT Solar energy utilisation is pivotal for advancing sustainable and renewable energy solutions, yet the rational design of high‐efficiency photothermal conversion devices remains a critical challenge. This paper systematically examines the evolution of photothermal reactor architectures from two‐dimensional (2D) to 3D structures, emphasising ...

Can Solar Limb Flare Prediction Be Properly Made by Extreme-ultraviolet Intensities?

The Astrophysical Journal Letters
We address the question of whether the solar limb flare prediction can be properly made by EUV intensity, which has less projection effects than solar white light and magnetogram data.

Cooling Bromine‐Contained Photovoltaic Perovskites: The Impact of Phase Segregation and Lattice Expansion

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
An optimal bromine content stabilizes the perovskite lattice during extreme temperature cycling by suppressing vacancies and regulating crystal growth, enhances open‐circuit voltage of the device by enhancing defect relaxation via lattice expansion.
