Introducing Chemical Vapor Etching (CVE): A Material‐Selective Approach for Surgically Precise Tarnish Removal

Small, EarlyView.
ABSTRACT The controlled removal of corrosion products is a persistent challenge in fields ranging from industrial alloy protection to cultural heritage conservation. Achieving high precision and selectivity in subtractive treatments remains difficult because of chemical complexity and structural heterogeneity of the corrosion layers.

Sn Galvanic Exchange Enables Creation of Trimetallic Multiphase Plasmonic Nanoparticles

Small, EarlyView.
A compositionally versatile synthesis strategy has produced trimetallic nanoparticles with textured surface morphologies, coexisting alloy and intermetallic phase structures, and tunable plasmonic responses. The galvanic exchange of Sn within Au─Sn seeds provides access to Au─Sn─M (M = Pd, Rh, Cu) nanoparticles that maintain long‐range structural order

Do We Really Know Why Carbon Nanotubes Grow?

Small, EarlyView.
The CNT growth mechanism is still debated. We propose a heterogeneous (2D) classical nucleation framework comparing pathways for graphenic patches, caps, and full CNTs. Despite its simplicity, it rationalizes key trends, including the correlation between catalyst particle size and CNT diameter.
