The support from the Office of Naval Research over the past 3 years has enabled us to make significant contributions to interest important to the Navy. Our research has focused in three areas. In the first area we have been advancing our understanding of aqueous surfaces as they pertain to understanding how water interacts with other media. We have been able to obtain detailed pictures of how water surfaces behave in the presence of high acid concentrations and adjacent to halocarbon surfaces. In the second area we have been examining the structure of molecular films that have important relevance to tribology. In these studies we have been working to understand how films assemble at surfaces and how to construct robust surfaces that can withstand chemical and physical pressures. The third thrust has been in developing molecular modeling capabilities to augment our experimental studies. These modeling capabilities have been extremely successful in giving us insights into how molecules behave at buried interfaces, particularly when in contact with other fluid media. As we move towards topics in environmental mediation in the coming funding period, the results of these current efforts will be invaluable.
