The adsorption of isobutane on a Pt(533) stepped surface has been investigated using temperature programmed desorption (TPD) and reflection absorption infrared spectroscopy (RAIRS). Isobutane exists in two monolayer states and one multilayer phase on the P ...
In order to understand better the mechanism of action of a permanent modifier based on Ir deposited on graphite furnaces pretreated by carbide-forming elements (W and Zr) an XPS investigation was carried out on samples submitted to thermal treatment simula ...
Comprehensive in-situ bioreactor monitoring and control based on a midinfrared spectroscopic sensor system M. Rhiel1, C. Cannizzaro1, S. Valentinotti2, I. Marison1, U. von Stockar1 1 Institute of Chemical Engineering, 2Institute of Automatic Control Swiss ...
The photochem. of ICN isolated in Ar matrixes has been investigated using UV absorption and laser spectroscopy under a variety of exptl. conditions. Laser excitation of the repulsive ~A continuum gives rise to long-lived near-IR emission from stabilized I ...
Local and superficial near-infrared (NIR) optical-property characterization of turbid biological tissues can be achieved by measurement of spatially resolved diffuse reflectance at small source–detector separations (
Infrared (IR) absorption spectroscopy and mass spectrometry have been simultaneously applied to dusty radiofrequency (RF) plasmas in methane, acetylene and ethylene. The combination of IR absorption spectroscopy and mass spectrometry allows the chemical co ...
Summary form only given. We have developed a diagnostic of absolute concentration measurement based on a time resolved resonant absorption spectroscopy. The probe signal *OH(A2Σ+ -X2Π, λ≈308 nm) is generated in a high pulse voltage triggered DBD probe. ...
The spatially resolved reflectance of turbid media is studied at short source–detector separations (approximately one transport mean free path) with Monte Carlo simulations. For such distances we found that the first and second moments of the phase functio ...
We present a far infrared gas spectrometer which uses a thin film pyroelectric detector integrated on silicon. The detector is in-house fabricated and consists of 1 x 50 elements of sol-gel deposited, zirconium rich lead titanate (PZT) which are suspended ...
The capability to perform absorption spectroscopy with hard x-rays was added to the synchrotron imaging spectromicroscopy technique. We present several successful test cases. First, the EXAFS (extended x-ray absorption fine structure) analysis was implemen ...
