Vapor-phase lubricants Nanometer-scale mechanisms and applications to sub-micron and rotating machinery was the beginning segment of a new program supported by AFOSR involving a set of experiments seeking to explore the molecular-scale properties of vapor-phase lubricants in well-defined contact geometries. During the 10.5 month grant period, two ultra-high vacuum chambers were customized for the specific proposed studies, and all personnel involved were trained in Ultra-High Vacuum UHV and quartz microbalance techniques. The construction and training period is now complete, and a series of measurements have been performed. These include measurements of the uptake rate of the lubricant TBPP on Fe as a function of temperature, and a series of measurements of the nanomechanical properties of a number of potential lubricants for Micro-Electro-Mechanical Systems MEMS applications by means of a combined quartz microbalancescanning tunneling microscopy technique.
