Giant Nonequilibrium Valley Control via Spin‐Selective Hot‐Carrier Transfer in an Antiferromagnetic van der Waals Stack

Advanced Materials, EarlyView.
Spin‐selective hot‐carrier transfer across CrSBr/WSe2/CrSBr interfaces couples the continuously tunable magnetic configuration of antiferromagnetic CrSBr to the valley degrees of freedom of monolayer WSe2, enabling giant nonequilibrium valley control and magnetic‐state‐dependent reversal of circularly polarized emission.

PALEOS: Multiphase equations of state and mass–radius relations for exoplanet interiors★

Astronomy & Astrophysics
Modeling the interior of a rocky or water-rich exoplanet is fundamentally a thermodynamic closure problem. Every layer’s density, temperature gradient, and phase state must follow from an equation of state (EoS) that stays self-consistent across the many

From Dark Photocatalysis to Photobattery‐Type Operation: A Re‐Functionalized Ti‐MOF for Solar Energy Storage

Advanced Materials, EarlyView.
ReCl47‐bpy is developed as a solar‐rechargeable, Re‐functionalized two‐dimensional metal–organic framework (MOF) for light‐driven charge storage and dark utilization. Re–bipyridine sites stabilize photoinduced electrons, enabling two complementary configurations: a MOF suspension for long‐lived charge retention and dark H2 evolution, and a spin‐coated ...

Resolving core-envelope degeneracies in giant planets and sub-Neptunes: Constraining the equivalence in the presence of dilute gradients

Astronomy & Astrophysics
Context. The widespread recognition of dilute, ‘fuzzy’ cores in giant planets and massive volatile mantles in sub-Neptunes has transformed planetary interior modelling into a highly degenerate, multi-dimensional problem. Aims.
