Effect of substrate on surface-enhanced Raman scattering of molecules adsorbed on immobilized silver nanoparticles
Article Abstract:
Effect of substrate on surface-enhanced Raman scattering of molecules adsorbed on immobilized silver nanoparticles was studied by assembling Ag nanoparticles on polyvinylpyridine (PVP) derivatized glass slides. It was shown that the positive charge of the PVP layer could alter the charge distribution in the immobilized nanoparticles and induce the formation of the dipole in the nanoparticles, leading to less charge transfer from the metal to the adsorbed molecules.

Selective adsorption of pyridine at isolated reactive sites on Si(100)
Article Abstract:
The investigation was conducted on the interaction of pyridine with isolated reactive sites on partially H-terminated Si(100), to restrict adsorption to the dative bonded form, while dative bonding on isolated clean dimers was observed, single dangling bonds remain unreacted. The results suggest that a single clean Si dimer is the smallest unit required for this process to proceed and it was predicted that phosphine would not react with isolated Si dangling bonds.

Adsorption of 1,10-phenanthroline within dodecanethiol monolayer: An approach to a switchable electrode surface
Article Abstract:
A simple method was used to prepare a 'switchable' electrode surface by using self-assembled monolayers of dodecanethiol on a gold electrode. The dodecane-modified electrode was electrochemically inactive until the monolayer was soaked in solution of 1,10 phenanthroline or 2,2'-bipyridine.
