Resonant Domain Wall Dynamics in a Three‐Dimensional Magnetic Nano Double Helix

open access: yesAdvanced Materials, EarlyView.
3D magnetic nanostructures promise exciting possibilities for magnetization dynamics. However, experimental realizations remain scarce. In nanoprinted cobalt double helices, time‐resolved X‐ray microscopy reveals harmonic domain wall dynamics. Simulations identify the mode and additional higher‐frequency resonances, revealing a rich dynamic landscape ...

A Simple Descriptor for Solid‐State Ionic Conductors Across Chemistries

open access: yesAdvanced Materials, EarlyView.
Researchers develop a simple and transferable descriptor, distance contraction, for solid‐state ion migration across Li‐, Na‐, K‐, and Mg‐ion conductors and diverse anion chemistries. By capturing the maximum local contraction experienced by the migrating ion, the descriptor enables rapid materials screening and unifies diverse ion‐transport mechanisms.

Anchored Fluoro‐Shielded Solvation for Lithium Metal Batteries

open access: yesAdvanced Materials, EarlyView.
Anchored fluoro‐shielded solvation reconstructs PVDF‐based polymer electrolytes by coupling polyanionic Li+‐solvate sites with fluorinated shielding segments. This design organizes anion‐rich solvation networks, strengthens selective Li+ transport, and generates LiF‐rich solid electrolyte interphase, enabling high conductivity, wide oxidative tolerance,

Catholic Schools and Bad Behavior: A Propensity Score Matching Analysis [PDF]

open access: yes
Although there is a sizeable literature on the effect of private school attendance on academic student outcomes, the number of studies that investigate the impact of school sector on non-academic outcomes is limited. Using a rich data set, we analyze the

Molecular Bridging Flexibility Enables Closed‐Pore Engineering in Hard Carbon for Enhanced Plateau Sodium Storage

open access: yesAdvanced Materials, EarlyView.
Molecular bridging flexibility is introduced as an effective precursor‐design strategy to engineer closed pores in hard carbon Flexible polymer precursors promote curved carbon skeleton formation and pore‐mouth closure, enabling enhanced low‐voltage plateau sodium storage. The optimized hard carbon delivers 3561 mAh g−1 reversible capacity and 2427 mAh

Scalable Hybrid Photocatalysts for Visible‐Light Degradation of Waterborne Organic Contaminants

open access: yesAdvanced Materials, EarlyView.
Covalently immobilizing the industrial dye benzothioxanthene imide onto macroscopic oxides creates H‐aggregates that drive co‐catalyst‐free radical generation under visible light. This system completely degrades diverse organic micropollutants into carbon oxides, maintaining full activity over 12 months.
