Rheo-optical fourier transform IR spectroscopy of polyurethane elastomers - 1. Principle of the method and measurements at ambient temperatureRheo-optical FTIR spectroscopy has emerged as an extremely valuable tool to study deformation phenomena in polymeric solids. With the aid of a specially designed...
Title: Method for determining contamination of material using mid-ir spectroscopy.Abstract: A method of determining contamination on a material having suspected contamination includes irradiating the material having suspected contamination with infrared energy over a spectrum of wavelengths; detecting the ...

In summary then, we have demonstrated successful operation of a broadly tunable picosecond infrared source that is continuously tunable and that permits the extension of the picosecond spectroscopy field over a wide region in the infrared. The bandwidth and operating wavelength are completely controlled ...
The effect of the substrate metals on the catalytic activity of ORR has been studied with some experimental methods, including scanning tunneling microscopy (STM) [11], photoelectron [12], and vibrational spectroscopy [13]. However, those methods could only give indirect information about adsorption...
