On‐Chip Active Non‐Reciprocal Topological Photonics
An ultra‐compact and efficient on‐chip isolator is experimentally demonstrated by integrating magneto‐optical InSb onto a terahertz silicon topological chip. The simultaneous breaking of spatial and temporal reversal symmetries forms a valley‐conserved non‐reciprocal waveguide mode, enabling a compact cavity size of 6.4 × 2.5λ2 and a low insertion loss

Metal‐covalent organic frameworks (MCOFs) are novel porous materials that exhibit the advantages of covalent and metal‐organic frameworks. However, it is extremely difficult to resolve their atomic structure and better understand their structure‐properties relation. This work utilizes a synergistic combination of advanced microscopy, spectroscopic, and

Emergent Locomotion in Self‐Sustained, Mechanically Connected Soft Matter Ringsf
Thermally fueled, self‐moving twisted rings made from liquid crystal elastomers are investigated. By studying single rings and linked knots, it is shown how autonomous locomotion emerges through coupling between the rings. The movement is programmable via handedness control at connection points, offering insights into collective behavior and ...

Enhanced Deformability Through Distributed Buckling in Stiff Quasicrystalline Architected Materials
Quasi‐periodic metamaterials combine stiffness and large‐strain deformability, overcoming limitations of traditional stretching‐dominated periodic designs that are prone to global buckling instabilities and catastrophic layer collapses. By leveraging non‐uniform force chains, they achieve high isotropic stiffness, stable deformation, and remarkable ...

Tuning the Morphological Properties of Granular Hydrogels to Control Lymphatic Capillary Formation
Tuning the morphological properties of granular hydrogels is essential to generate robust lymphatic capillary networks that express key lymphatic gene and protein markers. The study demonstrates that 3D in vitro lymphatic tube formation is controlled not by the mechanical properties of the gel, but by the pore size and topology (periodicity) of the gel
