The Reversal of a Solar Prominence Rotation about Its Ascending Direction during a Failed Eruption
Astrophysical Journal, 2018 The magnetic orientation of solar coronal mass ejections (CMEs) near the Earth’s magnetosphere is one major parameter that influences the geoeffectiveness of CMEs. The orientation often varies during the eruption and propagation from the Sun to the Earth

Advanced Functional Materials, EarlyView.HKUST‐1/TiO2 composite materials show a very high photocatalytic hydrogen evolution rate which increases as a function of the irradiation time until reaching a plateau and even surpasses the performance of the 1%Pt/TiO2 material after three photocatalytic cycles.

Solar Prominence Diagnostics [PDF]
International Astronomical Union Colloquium, 1998 AbstractThis paper reviews the diagnostic techniques currently used to establish estimates of the physical properties of prominences. Most often the fine structure of prominences cannot be resolved. Because of this and the complex structures and the varied forms of prominences, it is difficult to establish definitive values for temperature, density ...

TIME EVOLUTION OF PLASMA PARAMETERS DURING THE RISE OF A SOLAR PROMINENCE INSTABILITY [PDF]
, 2014 We present high-spatial resolution spectropolarimetric observations of a quiescent hedgerow prominence taken in the He i 1083.0 nm triplet. The observation consisted of a time series in sit-and-stare mode of ∼36 minutes duration.

Coronal Mini-jets in an Activated Solar Tornado-like Prominence [PDF]
Astrophysical Journal, 2020 High-resolution observations from the Interface Region Imaging Spectrometer reveal the existence of a particular type of small solar jet, which arose singly or in clusters from a tornado-like prominence suspended in the corona.

Three-dimensional Velocity Fields of the Solar Filament Eruptions Detected by CHASE
The Astrophysical Journal LettersThe eruption of solar filaments, also known as prominences appearing off limb, is a common phenomenon in the solar atmosphere. It ejects massive plasma and high-energy particles into interplanetary space, disturbing the solar-terrestrial environment.

Advanced Functional Materials, EarlyView.This work demonstrates the successful integration of a phenanthroline‐based 2D COF with MnI catalytic sites into a catholyte‐free membrane‐electrode‐assembly cell for CO2 electroreduction. The crystalline COF actively suppresses Mn⁰–Mn⁰ dimerization, achieving a turnover frequency of 617 h⁻¹ at 2.8 V (full‐cell potential), and enabling stable operation.
