The Department of Energy's Office of Industrial Technologies (OIT) Technical Assistance Program provides the tools and assistance to help manufacturers identify their best energy-efficient, pollution-preventing options, from a systems and life-cycle cost approach. Technical Assistance focuses on five key opportunities for energy efficiency and waste reduction: electric motors, steam, compressed air, combined heat and power, and the Industrial Assessment Centers (IACs). By promoting the use of available technologies, Technical Assistance helps industry immediately impact its bottom-line performance and build its position in global markets.
The goal of this article is to illustrate the use of synchrotron radiation for investigating surface chemical reactions by photoelectron spectroscopy. A brief introduction and background information is followed by examples of layer resolved spectroscopy, oxidation and sulfidation of metallic, semiconducting and oxide surfaces.
