Programmable Information Processing With Reconfigurable Self‐Contact Variable Stiffness Mechanical Metamaterial [PDF]

Advanced science
Reconfigurable self‐contact variable stiffness metamaterials based on shape memory polymers enable programmable stiffness switching. Static arrays store and encrypt information with immunity to electromagnetic interference, while asymmetric stiffness converts symmetric vibration into directional matter transport.

Programming Structural Symmetry and Emission in Low-Dimensional Hybrid Perovskites via Time and Temperature. [PDF]

Adv Sci (Weinh)
We demonstrate programmable structural symmetry and emission in benzylammonium‐based low‐dimensional hybrid perovskites. Continuous shaking transforms orthorhombic platelets into a lower‐symmetry monoclinic phase with broadband emission, whereas thermal activation drives the reverse pathways toward a higher‐symmetry configuration resembling the ...
