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

We demonstrate successful fabrication of high‐quality α‐Sn/β‐Sn planar nanostructures with arbitrary shapes by focused laser irradiation on topological Dirac semimetal α‐Sn thin films. The irradiated regions transform into atomically smooth, superconducting β‐Sn with a critical temperature of 3.7 K.

Adaptive Twisting Metamaterials
This work introduces torque‐controlled twisting metamaterials as a transformative platform for adaptive crashworthiness. By combining multiscale predictive modeling with experimental validation on additively manufactured gyroids, it demonstrates tunable stiffness, collapse stress, and energy absorption.

Artificial Symbiosis for Bulk Production of Bacterial Cellulose Composites
Co‐cultivation of the cellulose‐producing bacterium with the microalga enables bulk formation of bacterial cellulose under static incubation, with photosynthetically active oxygen‐generating sites throughout the medium. This symbiotic platform supports 3D cellulosic constructs with geometries dictated by the vessel shape.
