Quasiperiodic Oscillations of Flare Loops and Slipping Motion of Ribbon Substructures during a C-class Flare

The Astrophysical Journal
Quasiperiodic oscillations in solar-flaring emission have been observed over the past few decades. To date, the underpinning processes resulting in the quasiperiodic oscillations remain unknown.

Extreme-ultraviolet (EUV) observables of simulated plasmoid-mediated reconnection in the solar corona [PDF]

Understanding the role of magnetic reconnection in the heating and dynamics of the solar atmosphere requires detailed observational data of any observable aspect of the reconnection process, including small-scale features such as plasmoids.

Green Hydrogen for Public Transportation: Insights From an ABM and From Palma de Mallorca Case Study

Business Strategy and the Environment, EarlyView.
ABSTRACT The development of green hydrogen (GH2) value chains is crucial for decarbonizing sectors such as transport and industry. Their emergence, however, requires coordination among diverse actors, technologies, and regulations, which traditional analytical approaches struggle to capture.

Charge exchange emission from solar wind helium ions

, 2006
Charge exchange X-ray and far-ultraviolet (FUV) aurorae can provide detailed insight into the interaction between solar system plasmas. Using the two complementary experimental techniques of photon emission spectroscopy and translation energy ...

Self-constrained Magnetic Reconnection of a Solar Flare Cospatial with a Nonejected Filament

The Astrophysical Journal Letters
For flares associated with eruptive filaments, the filament normally rises above the postflare loops. Here, we report an unusual event in which the postflare loops instead overlie a filament that remains nonejected throughout the flare.

Bismuth‐Based Semiconductors in Photocatalytic CO2 Reduction: Catalysts, Progress, and Future Perspectives

Carbon and Hydrogen, EarlyView.
This review systematically summarizes research progress on bismuth‐based semiconductor photocatalytic materials in the field of CO2 reduction. It focuses on elucidating the mechanisms by which four modification strategies—including heteroatom doping, oxygen vacancy engineering, microstructural control, and heterostructure fabrication—regulate band ...

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.

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.
