Mobility of Single Vacancies and Adatoms in Graphene at Room Temperature

Small, EarlyView.
This study reveals that single vacancies in ion‐irradiated graphene migrate ≈100 nm at room temperature, driven by 0.8% tensile strain. Employing a nanopore mask, defect generation is spatially confined ansurrounded by non‐irradiated material, enabling direct observation of vacancy and adatom dynamics.

Amplification of Photochemical Chiroptical Activity of Chiral Gold Nanocubes

Small, EarlyView.
“Chiral gold nanocubes (AuNCs) enable polarization‐dependent plasmonic catalysis with exceptional photochemical circular dichroism. Circularly polarized light drives hot‐electron‐induced reactions with asymmetric reaction rates, monitored via operando SERS, with photochemical g‐factors exceeding optical limits.

Effect of Magnetic Anisotropy and Gradient‐Induced Dzyaloshinskii‐Moriya Interaction on the Formation of Magnetic Skyrmions

Small, EarlyView.
Magnetic force microscopy of gradient‐induced CoPt films reveals that magnetic skyrmion size and density vary with film thickness, gradient polarity, and applied magnetic field. An increased skyrmion density is observed in films exhibiting higher magnetic anisotropy.
