Near‐Infrared Cocrystal Nanofluorophore with Enhanced Two‐Photon Absorption Cross Sections

Advanced Science, EarlyView.
In this study, organic cocrystal nanoparticles (BP4TC‐NPs) were prepared via a nanoprecipitation method using an amphiphilic surfactant. The resulting cocrystal nanoparticles exhibit exceptional nonlinear optical properties and bioimaging capabilities.

Realization of a Bilayer Elastic Topological Insulator

Advanced Science, EarlyView.
Bilayer elastic wave topological insulators are experimentally realized, introducing the layer degree of freedom to access four topological phases. This enables diverse domain walls and transmission behaviors, including interlayer conversion and beam splitting.

Charge‐Acoustic Phonon Coupling Determined Carrier Transport Properties in FAxMA1−xPbBr3 Perovskite Single Crystals

Advanced Science, EarlyView.
This study investigates acoustic phonon‑carrier coupling in FAxMA1−xPbBr3 single crystals using time‑domain Brillouin scattering. The results show that increasing the FA content in FAxMA1−xPbBr3 single crystal reduces both the elastic constant and the intrinsic carrier mobility governed by the acoustic phonon‑carrier coupling.

Lattice Dynamics Across the High‐Pressure Phase Transition in CrTe

Advanced Electronic Materials, EarlyView.
ABSTRACT High‐pressure physics provides a powerful means of tuning interatomic interactions, enabling the discovery of novel structural and physical phenomena in materials. Chromium telluride, a transition metal chalcogenide, is particularly responsive to such external stimuli, exhibiting a broad spectrum of pressure‐, temperature‐, and stoichiometry ...
