An all‐dielectric asymmetric gammadion metasurface exhibits visible circular dichroism governed by helicity‐selective multipolar excitations. Quadrupole‐dominated and weaker mixed‐mode resonances are identified, and their distinct near‐field optical chirality and angular responses are revealed, establishing a direct link between structural asymmetry ...

High‐Energy Topological Edge States and Strain‐Induced Multiple Flat Bands in a Honeycomb Lattice
This work proposes a novel anti‐twig edge in the honeycomb lattice that supports two symmetric high‐energy edge states. Moreover, the suppression or enhancement of the high‐energy edge state is observed, and strain‐induced multiple flat bands are produced.

Nanosecond infrared laser (NIRL) low‐volume sampling combined with shotgun lipidomics uncovers distinct lipidome alterations in oropharyngeal squamous cell carcinoma (OPSCC) of the palatine tonsil. Several lipid species consistently differentiate tumor from healthy tissue, highlighting their potential as diagnostic markers.

Speckle‐Engineered Upconversion Amplification in Nanoemulsion‐Templated Hydrogel Microdomes
Nanoemulsion‐confined PEGDA microdomes generate speckle‐like excitation fields that strongly amplify upconversion luminescence upon dehydration, enabling filter‐free visible readout with reversible on–off switching. DMD‐based lithography yields scalable, shape‐programmable arrays for moisture‐responsive displays and optical encryption.
