The Astrophysical Journal LettersThe minimum value of the geomagnetic aa index has served as a remarkably successful predictor of solar cycle amplitude. This value is reached near or just after sunspot minimum, when both the near-Earth solar wind speed and interplanetary magnetic field (

Advancing Energy Materials by In Situ Atomic Scale Methods
Advanced Energy Materials, Volume 15, Issue 11, March 18, 2025.Progress in in situ atomic scale methods leads to an improved understanding of new and advanced energy materials, where a local understanding of complex, inhomogeneous systems or interfaces down to the atomic scale and quantum level is required. Topics from photovoltaics, dissipation losses, phase transitions, and chemical energy conversion are ...

Active‐Site Photothermal Energy Utilization in PET Depolymerization
Angewandte Chemie, EarlyView.Photothermal catalysis enables efficient PET depolymerization, yet the role of active‐site temperature remains unclear. A catalytic activity reversal between Pd–CNG and PdPOM–CNG is observed under thermal and photothermal conditions. Efficient nanoscale photothermal energy delivery raises active‐site temperature, compensates for lower intrinsic ...

Advanced Energy Materials, EarlyView.The additive EDTMPS inhibits hydroxides deposition by chelating with Ca2+/Mg2+. It also disrupts the hydrogen bond network of interfacial water and expands the thickness of electric double layer, promoting more free water to flip into adsorbable O‐down configuration.

The Long-term Evolution of the Solar Transition Region
The Astrophysical JournalLong-term evolution characteristics of the solar transition region have been unclear. In this study, daily images of the solar full disk derived from the observations by the Solar Dynamics Observatory/Atmospheric Imaging Assembly at 304 Å wavelength from

The Interoperability Challenge in DFT Workflows Across Implementations
Advanced Intelligent Discovery, EarlyView.Interoperability and cross‐validation remain major challenges in the computational materials science. In this work, we introduce a common input/output standard that enables internal translation across multiple workflow managers—AiiDA, PerQueue, Pipeline Pilot, and SimStack—while producing results in a unified schema.

Magnetic Fields on Solar-Type Stars: The Solar-Stellar Connection
, 2016 Our understanding of solar magnetic fields is significantly more detailed than we can achieve for other stars. However, over the last few decades, techniques such as Zeeman Doppler Imaging (ZDI), have delivered major advances in the study of stellar ...
