Bismuthene Under Cover: Graphene Intercalation of a Large Gap Quantum Spin Hall Insulator
Bismuthene, a quantum spin Hall insulator with a massive 800 meV topological gap, holds great potential for room‐temperature devices but rapidly degrades in air. This study demonstrates that intercalating bismuthene between SiC and a graphene sheet preserves its structure and topology while preventing oxidation, enabling ex‐situ experiments and ...

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

Carbonization Tuned Core‐Shell Fe3O4@C Nanostructures with Enhanced Electromagnetic Wave Absorption
The core‐shell structured Fe3O4@C composites are prepared by employing an in situ polymerization and carbonization treatment method. The effect of carbonization temperature on electromagnetic wave absorption of H‐FO@C composites is symmetrically analyzed, and the impedance matching and attenuation ability are improved significantly by controlling ...

Strain relaxation of Al‐rich α‐(AlGa)2O3 single layers and an α‐Al2O3/Ga2O3 superlattice structure grown on m‐plane sapphire substrates by molecular beam epitaxy are discussed. V‐shaped dislocations are formed on the Al‐rich α‐(AlGa)2O3 sample surface to reduce elastic strain energy accumulated during growth.
