Designing Vanadium‐Based Oxide Electrocatalysts for Water Splitting: Experimental and Mechanistic Insights with Machine Learning

Advanced Functional Materials, EarlyView.
This review establishes structure‐property‐mechanism relationships across six modification strategies for V‐based oxide water‐splitting electrocatalysts: lattice engineering, heteroatom doping, interface engineering, carbon‐based hybridization, morphology engineering, and surface reconstruction and pre‐catalyst design, where dissolution is reframed as ...

Which Polar Precursor Better Predicts Solar Cycles: Axial Dipole Moment or Hemispheric Polar Flux of the Sun?

The Astrophysical Journal
Accurate forecasting of future solar cycle amplitudes is crucial because solar activity modulates the near-Earth space environment, yet such predictions remain a long-standing challenge in solar physics.

Statistical study of ICMEs and their geoeffectiveness during the rising phases of Solar Cycles 23, 24, and 25

Earth and Planetary Physics
As Solar Cycle 25 appears to approach the declining phase, to objectively evaluate the activity intensity during its rising phase and conduct a comparative analysis, we extend the catalog of Interplanetary Coronal Mass Ejections (ICMEs) from 2016 to 2025.

Photo‐Switchable Molecular Module Programming PET Biodegradation in Aquatic Environments

Advanced Functional Materials, EarlyView.
We address the plastic durability paradox by integrating an itaconic acid–derived pyrrolidone module into polymer backbones. Sunlight in water triggers Norrish Type I ring‐opening and hydrophilization, enabling rapid biodegradation into nontoxic minerals.

Architecture‐Driven Functional Coupling in Vertically Aligned Nanocomposites

Advanced Functional Materials, EarlyView.
Vertically aligned nanocomposites define a growth‐engineered architecture in which vertical interfaces, strain fields, defect pathways, and phase connectivity are created simultaneously. This review shows how these architectural features couple ferroic, optical, ionic, electrochemical, and device responses, establishing design rules and open challenges

Solar cycle evolution of ICME sheath regions at 1 AU

Astronomy & Astrophysics
Aims. We investigate the evolution of interplanetary coronal mass ejection (ICME) sheath regions at 1 AU across solar cycles 23, 24, and the rising phase of 25, focusing on their variability and turbulence in relation to upstream solar wind conditions ...

Covalent Functionalization of 2D Semiconductors: A Roadmap to Advanced Electronic Devices

Advanced Functional Materials, EarlyView.
This Review presents recent advances in the covalent functionalization strategies for two‐dimensional semiconductors and their implementation in modern technologies. Layered materials are modified through diverse molecular chemistries (e.g., thiols, diazonium salts, alkyl halides, and electron‐deficient species) to tailor their surface properties ...

Observation-based Iterative Map for Solar Cycles. I. Nature of Solar Cycle Variability

The Astrophysical Journal
Intercycle variations in the series of 11 yr solar activity cycles have a significant impact on both the space environment and climate. Whether solar cycle variability is dominated by deterministic chaos or stochastic perturbations remains an open ...
