“…It is essential to characterize the chemical state and structure of the working catalyst. This requires specialized instrumentation so these supported catalysts can be prepared under well-defined conditions (e.g., reduced in H 2 at a given temperature and pressure) and then transferred directly into UHV for surface analysis[20, 21]. Since supported nanoparticles in both metallic and sulfided states are highly reactive and will quickly oxidize when exposed even briefly to air at room temperature, special care must be taken to avoid any exposure to the atmosphere when the transfer into UHV is made[21].…”

Surfaces and interfaces play a critical role in material performance in many applications including catalysis, biomaterials, microelectronics, tribology and adhesion. Characterizing the important surfaces and interfaces involved in each application may present different challenges, but the approach to investigating them often is rather similar. Specialized instrumentation is typically used to probe the surface region of a material and often times it is required to develop new instrumentation and data analysis methods to obtain the desired information. It usually best to use multiple experimental techniques, often coupled with theoretical calculations and simulations, to gain a more complete understanding of the surface and interface regions. Careful handling and preparation of the samples is required so the surface is not altered during these processes as well as during analysis. Using model samples with well-defined surface structures and compositions can provide information about fundamental processes as well as help develop the analytical tools and methodology needed to characterize complex surfaces and interfaces. Thus, the expertise and experience a surface analyst acquires in one field can be readily applied to other fields, even when those fields are significantly differently (e.g., biomaterials and microelectronics). This has resulted in surface analysts moving rather easily between different research and application areas. As one example my career path of small molecule chemisorption and reactivity on single crystals to industrial catalysis to biomedical surface science is presented in this manuscript.
