G-SIMS of biodegradable homo-polyesters
No full textInternational audienceStatic SIMS (SSIMS) is a powerful surface analytical technique which can provide detailed molecular information from organic surfaces. However, often much of the acquired information is too rich in detail and the data analysis relies on analysts' expertise and/or the limited number of materials in SSIMS libraries. Gilmore and Seah [Appl. Surf. Sci. 161 (2000) 465] recently developed a library independent technique, G-SIMS where extrapolation of the data to low surface plasma temperature reveals the un-degraded parent fragments from the SSIMS spectra. In this study, G-SIMS has been tested on biodegradable polyesters including: poly(glycolic acid) (PGA), poly(lactic acid) (PLA), poly(hydroxybutyrate) (PHB) and poly(caprolactone) (PCL). These materials are chosen to test G-SIMS capabilities on these structurally related compound series. The G-SIMS spectra derived from the SIMS spectra acquired from these polyesters yielded vital clues to fragmentation mechanisms as a function of molecular structure and highlight a powerful application of G-SIMS
Quantitative SIMS Depth Distribution of Nitrogen in Nitrided Oxide at the SiO2/Si Interface
No full textNitridated gate oxides are quite common to be used in VLSI/ULSI MOS devices. Since this material presents several advantages compared with traditional silicon oxide [1, 2], there are strong research efforts both in developing it and in studying its chemical and electrical properties. To estimate the distribution of nitrogen in nitridated oxide, electron spectroscopies (Auger, XPS) have been frequently employed [3]. The limit in their sensitivity is around 1021 atoms/cm3. SIMS studies have been seldom used and normally applied to measure the hydrogen content [4,5,6]. In this paper we present SIMS analytical methodology giving a quantitative nitrogen distribution in systems like SiOxNy/Si by employing of suitable standards. To get a proper quantification at interface region we used as RSFs a linear extrapolation of Si and SiO2 RSFs weighting them by a factor proportional to tht oxigen signa

J. B. Sims and the Board of Light & Power
No full textJames Sims worked for Grand Haven's Board of Light & Power from 1937 to 1963 and in time became the CEO of the company. He received his engineering degree from Texas A&M University and was trained in the Army Air Corps. In this interview, he talks about his love for flying along with the financing and development of the Grand Haven Municipal Air Park. He also discusses his experience with private and public owned electrical companies in Texas and Michigan, his electrical work on local area fountains, and his consultation for other communities in the development of power plants. Upon his retirement from the Board of Light & Power, the company undertook the development of a new facility, located on Harbor Island, and named it after Sims
