Quantitative FT-IRRAS spectroscopic studies of the interaction of avidin with biotin on functionalized quartz surfaces
Article Abstract:
The interaction of avidin with biotin is studied on functionalized quartz surfaces with the use of Fourier transform infrared reflection-absorption spectroscopy (FT-IRRAS). It is indicated that the biotinylated 3-amniopropyltrimethoxysilane (3-APTMS) layer exhibits a very low specific binding capacity for avidin (on the order of 0.15 pmol of avidin/cm(super 2)) and substantial nonspecific adsorption.

FTIR studies of CO absorption on Al2O3 and SiO2 supported Ru catalysts
Article Abstract:
The adsorption of CO on Al2O3 and SiO2 supported Ru catalysts is investigated through FTIR spectroscopy. Deconvolution of the spectra obtained reveals the presence of 11 distinct bands in the case of Ru/Al2O3 and 10 bands in the case of Ru/SiO2, which were assigned to different carbonyl species absorbed on reduced as well as partially oxidized Ru sites.

Characterization of CuO supported on tetragonal ZrO2 catalysts for N2O decomposition to N2
Article Abstract:
A series of tetragonal zirconia-supported CuO oxide catalysts with various CuO loadings are characterized. The results indicate that the dispersion capacity of copper oxide on this support is approximately 8.6 Cu(super 2+) ions/nm(super 2) ZrO2.
