Excitonic Anisotropy in Single‐Crystalline 2D Silver Phenylchalcogenides

open access: yesAdvanced Optical Materials, EarlyView.
Using a combination of ab initio theory and optical micro‐spectroscopy, in‐plane anisotropy of multiple delocalized excitons in 2D silver phenylchalcogenides (AgEPh; E = S, Se, Te) is predicted and characterized. Cryogenic reflectance micro‐spectroscopy further reveals the fine structure of excitonic bands in AgSePh.

Dual‐Mode Thermal Indicator for Cold‐Chain Logistics Using Multipiezo Li0.12Na0.88NbO3: Pr3+

open access: yesAdvanced Optical Materials, EarlyView.
Multipiezo Li0.12Na0.88NbO3:Pr3+ phosphor enables dual‐mode optical sensing by integrating fluorescence intensity ratio (FIR)‐based temperature readout and persistent luminescence‐based time tracking. The system achieves a record‐high relative sensitivity of 2.18% K−1 for FIR‐based thermometry in the 103–293 K range and allows for accurate ...

Bi–Sb Co‐Alloying Tunes Photoexcited State Dynamics in (4FPEA)4AgBi1−xSbxI8 Layered Double Perovskites through Structural Confinement

open access: yesAdvanced Optical Materials, EarlyView.
Lead‐free double perovskites are emerging alternatives to lead‐halide analogues, leveraging low toxicity and highly tunable chemical compositions. These materials possess unique carrier dynamics, often governed by self‐trapped exciton (STE)‐mediated recombination.

Integrin α8‐Mediated Pericyte Morphogenesis Controls Blood‐Brain Barrier Integrity

open access: yesAdvanced Science, EarlyView.
This study highlights that ITGA8 impacts pericyte morphology and function, both crucial for BBB integrity, via RhoA/ROCK signaling, thus influencing TGF‐β1 activation through cytoskeletal tension and ECM interactions. Notably, in post‐ischemic recovery models, ITGA8 deficiency exacerbates vascular dysfunction by impairing pericyte‐mediated BBB ...
