Advanced Functional Materials, EarlyView.Poly(acrylic acid) acts as a reaction‐time pH buffer during hydrothermal Sb2(S,Se)3 growth through its COOH/COO‐ equilibrium. When combined with ethanol‐regulated growth, this buffering strategy reduces Sb‐O related surface disorder, improves local electronic uniformity and carrier collection, and increases the champion solar‐cell efficiency to 10.25%,

Defect‐Mediated Inelastic Light Scattering by Infrared Phonons in Hexagonal Boron Nitride
Advanced Functional Materials, EarlyView.Optically active defects in hexagonal boron nitride enable inelastic stimulated light scattering mediated by infrared‐active phonons, relaxing conventional Raman selection rules. Defect engineering enhances the Stokes‐conversion process and activates both TO‐ and LO‐phonon scattering channels.

Role of Structural Disorder on Phonon Transport and Thermal Conductivity in Li6PS5Br
Advanced Functional Materials, EarlyView.Solid electrolytes are fast ion and slow heat conductors. Although both transport properties are governed by lattice dynamics and atomic structure, their interplay remains poorly understood. Here, we study this interrelation in anion‐ordered and disordered Li6PS5Br.

Advanced Functional Materials, EarlyView.High‐performing near‐infrared (NIR) organic light‐emitting diodes are demonstrated using an efficient and stable 800 nm‐emissive organic radical and a thermally activated delayed fluorescence (TADF) host. TADF‐assisted exciton generation combined with improved charge transport enables high external quantum efficiency (>8%), high radiance (>70,000 mW sr−

Emergent classicality in continuous quantum measurements
, 2013 We develop a classical theoretical description for nonlinear many-body dynamics that incorporates the back-action of a continuous measurement process. The classical approach is compared with the exact quantum solution in an example with an atomic Bose ...

Advanced Functional Materials, EarlyView.Here, we establish a low‐dose liquid‐phase electron microscopy workflow for real‐time observation of biological processes in hydrated conditions. Beam damage is reduced by imaging only 20% of the pixels and reconstructing the complete image using an inpainting algorithm.
