Enhanced adsorption of molecules on surfaces of nanocrystalline particles
Article Abstract:
A study was conducted to analyze the influence of particle size on the adsorption of molecules from a solution onto nanocrystalline particles. The overall free energy change for adsorption from solution onto a surface was characterized as a function of the chemical composition and structure of the solid. Results indicated that the rapid increase in adsorption during decreases in particle size has important implications on the modeling of natural and experimental systems.

Electrical and spectroscopy characterization of metal/monolayer/Si devices
Article Abstract:
A simple technique for vibrational spectroscopy of metal/monolayer/silicon structures was applied to study the interactions of Au, Al and Ti with the alkane monolayers, either assembled onto thin oxides or directly attached to Si. The results demonstrate extreme sensitivity of the monolayer/metal reactivity to the nature of the film/substrate bonding.

Optical and electronic anisotropy of a pi-conjugated molecular monolayer on the silicon(001) surface
Article Abstract:
The electronic and optical properties of an oriented monolayer of a pi-conjugated molecule, 9,10-phenanthrenequinone on a silicon(001) substrate are investigated. The experiments confirm that it is possible to create a macroscopic optical anisotropy in organic films on silicon surfaces using the Si(001) dimmers to control the molecular orientation.
