Adsorption and reaction of nitric oxide with atomic oxygen covered Au(111)
Article Abstract:
The adsorption/reaction of NO with an atomic oxygen covered Au(111) surface to form nitrogen di oxide was investigated using molecular beam scattering techniques. Results suggested that at temperatures above Ts approximately equal to 200K, the NO2 production was limited by NO surface lifetime on O/Au(111) and at temperatures below Ts approximately equal to 200 K NO2 production was limited by both a reduction in the NO2 reaction rate and NO2 desorption limitations.

SERS substrates fabricated by island lithography: The silver/pyridine system
Article Abstract:
Silver-containing structures are fabricated reproducibly for Surface-Enhanced Raman Scattering (SERS) spectroscopy use in analytical chemistry. The conclusion arrived is that in tdhe system studied the effective area of the SERS 'site'' must be large compared to the area occupied by the adsorbed pyridine, so that the SERS signal is proportional to the surface coverage, averaged over the adsorbent.

Self-assembly of silver nanoparticles: Synthesis, stabilization, optical properties, and application in surface-enhanced Raman scattering
Article Abstract:
Silver nanoparticle aggregates are compounded in large scale by applying resorcinol under alkaline condition to obtain a self-assembly of silver clusters. The surface-enhanced Raman scattering (SERS) intensity is found to be dependent on the state of aggregation of silver particles.
