Dynamo Confinement of a Radiatively Spreading Solar Tachocline Revealed by Self-consistent Global Simulations

open access: yesThe Astrophysical Journal Letters
The helioseismically observed solar tachocline is a thin internal boundary layer of shear that separates the rigidly rotating solar radiative zone from the differentially rotating convective zone and is believed to play a central role in the 22-yr solar ...

Crystal Facet‐Polysaccharide Matching in CFS‐P Nanocrystals Drives Fungal Uptake, Vacuole Destruction, and Selective Antifungal Activity

open access: yesAdvanced Science, EarlyView.
Facet‐engineered PVP‐capped CuFeSe2 nanocrystals exhibit potent, selective antifungal activity by strongly binding cell‐wall mannan, enabling vacuolar entry and organelle disruption. High‐index facets show superior mannan affinity, validated by theoretical calculations and experiments. CFS‐P induces vacuolar cavitation, mitochondrial abnormalities, and
