Reconfigurable Nanogap SERS for Multiscale Molecular Sensing on Curved Surfaces
Small, EarlyView.Reconfigurable Au‐coated SMP nanocomposites enable adaptive SERS through reversible tuning of Au─Au nanogaps. Embedded AgNPs serve as photothermal triggers and reinforcements. Wide gaps facilitate macromolecule detection, while narrowed gaps enhance small‐molecule signals for reliable multiscale sensing on curved surfaces.

Polarity‐engineered Sn‐Ti cluster photoresists for sub‐10‐nm high‐resolution lithography
Smart Molecules, EarlyView.Enhancing the polarity of clusters can optimize their patterning performance; inspired by this strategy, we designed polarity‐enhanced Sn‐Ti oxo clusters via ligand engineering. The optimal TS‐3 with exposure‐induced polarity switch achieves 8 nm patterning in lithography and achieves simultaneous improvement in resolution and patterning performance ...

Electric charge of nanopatterned silica surfaces
Physical Chemistry Chemical Physics, 2019 The surface charge density of a nanopatterned silica decreased at the pits but increased at the tips of surface patterns. For a case of self-repeating surface structures, the average of local surface charges becomes lower than the theoretical predictions.
