Photothermal–Magnetocaloric Coupled Evaporators for Actively Adjustable Water Evaporation and Oil–Water Purification in Complex Environments

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A photothermal–magnetocaloric coupled aerogel evaporator is developed for actively adjustable water evaporation in complex environments. Magnetocaloric heating provides active energy compensation under low‐light conditions and disrupts interfacial hydrogen‐bond networks to promote evaporation.

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

ENERGY &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 ...

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

The 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 ...

Rational design of Ni‐based catalysts for methane dry reforming: Recent advances and future perspectives

FlexMat, EarlyView.
Addressing the challenges inherent in dry reforming of methane (DRM), this paper focuses on the structural design and performance optimization of Ni‐based catalysts. The modulation strategies for DRM are systematically reviewed across four dimensions: the micromorphology of active metals, metal‐support interactions, electronic modifications by ...
