Asteroseismic Structure Inversions of Main-sequence Solar-like Oscillators with Convective Cores
The Astrophysical JournalAsteroseismic inferences of main-sequence solar-like oscillators often rely on best-fit models. However, these models cannot fully reproduce the observed mode frequencies, suggesting that the internal structure of the model does not fully match that of ...

Glissile Interphase Boundaries Enable Collective Phase Switching in Epitaxial Polar Oxides
Advanced Functional Materials, EarlyView.A triple point is identified in the phase diagram of low‐symmetry epitaxial BiFeO3 thin film along with an extended regime of phase competition associated with a flattened energy landscape. The electromechanical response is shown to be governed by correlated interphase‐boundary motion, including scale‐free avalanche dynamics characteristic of systems ...

Electrocapillary Modulated Interfacial Tension Amplifies Liquid Metal Transduction
Advanced Functional Materials, EarlyView.This study presented an electrocapillary‐enhanced magnetohydrodynamic pumping strategy that harnesses the Lorentz force and interfacial tension modulation of liquid metal droplets to achieve amplified fluidic power. The system enabled low‐voltage, self‐oscillating fluidic transduction with enhanced pressure and flow generation, supporting compact ...

Optical Signature of Moiré Superlattices Formed by Twisted SrTiO3 Membranes
Advanced Functional Materials, EarlyView.We discover optical signatures from bonded interfaces in twisted SrTiO3 moiré superlattices, including low‐frequency Raman vibrational modes and strong second‐harmonic generation, consistent with strong interlayer coupling inferred from cross‐sectional electron microscopy and ab initio calculations. ABSTRACT Moiré superlattices formed at the interfaces

Asteroseismology of Metal-poor Red Giants Observed by TESS
The Astrophysical JournalGalactic archeology has long been limited by a lack of precise masses and ages for metal-poor stars in the Milky Way’s thick disk. However, with TESS providing a growing number of photometric observations, it is possible to calculate masses and ages for ...

Correlated Metal LaNiO3 as a p‐Type Transparent Conductor
Advanced Functional Materials, EarlyView.p‐type transparent conducting oxides are needed to enable superstrate solar cell geometries with n‐type absorbers. The p‐type correlated metal LaNiO3 combines high optical transmission with low electrical resistivity and is compatible with a range of scalable deposition processes.
