The ultraviolet spectra of thin evaporated films of carbonaceous chondrite

Autor: Shin Yabushita, Kazuhiro Wada, E. T. Arakawa, T. Inagaki

Publikováno v: Astrophysics and space sciences. 206:111-117

Absorption spectra in the visible to the near ultraviolet were measured on the Belgica chondrite B-7904 in a form of thin solid film made by the vacuum evaporation. The spectra obtained exhibit a sharp peak at 226 nm and a broad bump around 280nm. Th

Detection and differentiation of biological species using microcalorimetric spectroscopy

Autor: Nickolay V. Lavrik, Slobodan Rajic, Panagiotis G. Datskos, E. T. Arakawa

Publikováno v: Ultramicroscopy. 97:459-465

We report on the application of infrared (IR) microcalorimetric spectroscopy ( micro -CalSpec) to the identification and detection of trace amounts of biological species. Our approach combines principles of photothermal IR spectroscopy with ultrasens

Study of different hormone-sensitive lipase concentrations using a surface plasmon resonance sensor

Autor: E. T. Arakawa, Thomas Thundat, Fredric B. Kraemer, A. Wig, Wen-Jun Shen, Fabrice Meriaudeau, Ali Passian, Shailja Patel, Trinidad L. Ferrell

Publikováno v: Sensors and Actuators B: Chemical. 73:192-198

This paper presents a series of experimental results including those based on the surface plasmon resonance (SPR) to investigate the parameters for determining the concentration and form of various hormone sensitive lipase (HSL) solutions. HSL is a r

Production and Optical Constants of Ice Tholin from Charged Particle Irradiation of (1:6) C2H6/H2O at 77 K

Autor: W. R. Thompson, L. Cheng, C. Sagan, Christopher F. Chyba, P. S. Tuminello, B. N. Khare, E. T. Arakawa, C. Meisse

Publikováno v: Icarus. 103:290-300

Fifty separate irradiations of a 6:1 mixture of H2O/C2H6 ice conducted over a 5-month period have yielded sufficient tholin for the determination of its physical constants in the 0.06 to 40 micron range. While the imaginary part of the refractive ind

Desorption studies of metal atoms using laser-induced surface-plasmon excitation

Autor: E. T. Arakawa, T. A. Callcott, Ida. Lee

Publikováno v: Physical Review B. 47:6661-6666

Au, Al, and Ag atoms have been desorbed from thin films on glass by laser-excited surface plasmons in an attenuated-total-reflection geometry. Desorption yields are measured as a function of angle of incidence near the optimum coupling angle and the

Optical properties of epitaxialCoSi2on Si from 0.062 to 22.3 eV

Autor: E. T. Arakawa, Leo J. Schowalter, J. R. Jimenez, Z.-C. Wu

Publikováno v: Physical Review B. 47:4356-4362

The optical constants of epitaxial CoSi[sub 2] films on Si from 0.062 to 22.3 eV have been determined by ellipsometry and reflectance measurements. The energy dependencies of the dielectric functions show Drude behavior at energies lower than [simila

Diffusion of Al into Au thin films studied by the ATR method

Autor: B. Loisel, E. T. Arakawa

Publikováno v: Applied optics. 19(12)

Alloy formation in Au-Al thin films has been studied by the attenuated total reflection (ATR) method in the 64-80 degrees C temperature range. In this optical method, the coupling of incoming light with a surface plasmon at the metal-dielectric inter

Polarization by gratings used at grazing incidence

Autor: E. T. Arakawa, James A. R. Samson, M. W. Williams

Publikováno v: Applied optics. 17(16)

The polarization introduced by gold-coated and aluminum-coated concave reflection gratings used in a grazing incidence monochromator has been measured over the spectral range from 20 nm to 130 nm. In every case the polarization ratio (P = R(p)/R(s))
