Integrated Solvent‐Catalyst‐Dopant Strategy via Acidic DES for Synthesizing Lignin‐Derived Carbon Dots With High‐Quantum Yield to Achieve Efficient Photocatalytic Degradation of Tetracycline

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A deep eutectic solvent (ChCl/pTSA) platform enables integrated solvent, catalyst, and dopant functions, producing sulfur‐doped carbon quantum dots with a high sp2‐C content (82.8%) and a quantum yield of 56.9%. When combined with TiO2, the CQDs form TiOC and TiOS interfacial bridges, achieving 97.3% tetracycline photodegradation with excellent ...

Global Coronal Plasma Diagnostics Based on Multislit Extreme-ultraviolet Spectroscopy

open access: yesThe Astrophysical Journal
Full-disk spectroscopic observations of the solar corona are highly desired to forecast solar eruptions and their impact on planets and to uncover the origin of solar wind. In this paper, we introduce a new multislit design (five slits) to obtain extreme-

How Small-scale Jetlike Solar Events from Miniature Flux Rope Eruptions Might Produce the Solar Wind

open access: yesThe Astrophysical Journal
We consider small-scale jetlike events that might make the solar wind, as has been suggested in recent studies. We show that the events referred to as “coronal jets” and as “jetlets” both fall on a power-law distribution that also includes large-scale ...
