Chiral Acoustic Phonon and Conservation of Pseudoangular Momentum in α‐Quartz

open access: yesAdvanced Materials, EarlyView.
Chiral acoustic phonons in α‐quartz are probed via Brillouin light scattering, exploiting the photon's helicity and the crystal's handedness. The interaction obeys a selection rule arising from pseudoangular momentum conservation, enabling direct optical access to phonon chirality in nonsymmorphic crystals.

Active Learning‐Guided Accelerated Discovery of Ultra‐Efficient High‐Entropy Thermoelectrics

open access: yesAdvanced Materials, EarlyView.
An active learning framework is introduced for the accelerated discovery of high‐entropy chalcogenides with superior thermoelectric performance. Only 80 targeted syntheses, selected from 16206 possible combinations, led to three high‐performance compositions, demonstrating the remarkable efficiency of data‐driven guidance in experimental materials ...

Stimuli‐Responsive Afterglow from Luminescent Liquid Crystal Elastomers

open access: yesAdvanced Materials, EarlyView.
An active glow luminescent system for encoding, signaling, and tracking in dark environments has been developed by integrating inorganic ultralong afterglow phosphors with adaptive liquid crystal elastomer actuators. Abstract Stimuli‐responsive luminescent polymeric materials which combine afterglow emission with mechanical flexibility and adaptability

Macrophages Mediate Mesoscale Brain Mechanical Homeostasis

open access: yesAdvanced Materials, EarlyView.
We investigated the role of infiltrating immune cells in sculpting the developing brain. Using Brillouin microscopy and active microrheology, we found microglia actively maintain tissue viscoelasticity. Moreover, colony stimulating factor one receptor (CSF1R)‐driven stromal remodeling alters brain mechanics in vivo. These findings link immune activity,
