Optical Access to Dark Excitons Via Spin–Phonon Fano Interference
Advanced Science, EarlyView.Dark excitons in quantum dots neither absorb nor emit light and stay hidden from optical spectroscopy. Quantum interference now reveals them: light scattered by acoustic phonons interferes with a phonon‐assisted spin flip between bright and dark exciton, carving a Fano dip into the spectrum whose position gives the bright–dark splitting. Magnetic field,

Advanced Science, EarlyView.Rapid solidification with glass fluxing is first applied to the intrinsic GeTe alloy and achieves large undercooling within 2 h. This enables partial retention of the high‐temperature cubic phase at room temperature and forms a crystallographically oriented α+β dual‐phase structure and a hierarchical defect network.

Skyrmion Bubbles by Design in a Centrosymmetric Kagome Magnet
Advanced Science, EarlyView.Chemical tuning of magnetocrystalline anisotropy in the centrosymmetric kagome magnet TmMn6Sn6 is shown to drive a spin reorientation transition via an intermediate magnetic fan state and to stabilize an emergent skyrmion bubble lattice. Four‐dimensional cryogenic Lorentz scanning transmission electron microscopy confirms the nanoscale texture ...

Product‐Reshaped Gas‐Phase Hydrodynamics Govern CO2 Electrolysis in Gas Diffusion Electrodes
Advanced Science, EarlyView.In gas‐fed CO2${\rm CO}_2$ electrolysers, the gas phase is part of the electrochemical response. As gaseous products form, they change gas composition and flow, which in turn affects CO2${\rm CO}_2$ delivery and CO intermediate availability. This feedback changes the reaction environment needed for multicarbon formation, becoming unavoidable as ...

Advanced Science, EarlyView.This Perspective charts the modeling landscape for soft manipulators, spanning sparse system identification, neural dynamics, physics‐informed models and hybrid intelligence. We examine how physics, data, sensing, adaptation and control can assume complementary roles within this landscape, and provide a framework for selecting modeling approaches ...

Advanced Science, EarlyView.A hybrid semi‐transparent perovskite‐photovoltaic and concentrating solar‐thermal collector is developed to spectrally split sunlight for simultaneous electricity and heat generation. The design achieves thermal decoupling between the photovoltaic and thermal components, offering a promising route for efficient co‐harvesting of solar electricity and ...
