FTIR spectra were measured and used to identify functional groups in the material. A simple comparison of standard spectra and samples proves that the FTIR technique is useful for monitoring functional groups in a mixed suspension. In this study, the chemical interaction between silica dioxide (SiO2...
Infrared spectra are reported of Pd/SiO2 and Pd-Cu/SiO2 exposed at 295 K to either CO followed by SO2 or SO2 followed by CO. Chemisorptive interaction of SO2 with bridging CO sites on Pd {100} faces created cationic Pd sites which adsorbed CO linearly. Multibonding CO sites on Pd {111...
FTIR spectra of spruce, beech, and bamboo MWL''s, representing G, GS and HGS lignins, were recorded and examined in the wavenumber range of 1800 to 700 cm1. The spectra were then submitted to a mathematical self-deconvolution technique i... O Faix,O Beinhoff - 《Journal of Wood Chemis...
Infrared emission spectra (FTIR) and crystallisation studies of the glassy CaO·MgO·2SiO2‐slag (900 – 1200°C)The application of Fourier-transform-infrared spectroscopy (FTIR) as a method for in-situ measurements of the spectral emission coefficient is described. During the transformation of the...

Nevertheless, the in-situ ATR-FTIR spectra of adsorbed BSA after [BSA] > 1 µM exhibits a decreasing in β-sheets/turns (1662 cm–1), and concomitant increments of short-segment connecting α-helix (1637 cm–1) and side chain moieties (1612 cm–1) (Fig. 3), which...
The MIR spectra of glasses and devitrificates of BPO4·2SiO2, BPO4 SiO2 and 2BPO4·SiO2 compositions have been shown. The bands arising from the Si–O, B–O and P–O bonds vibrations can be assigned in the spectra of the above samples. All bands appear almost at the same wavenumber...
3.1. IR spectra processing and exploratory classification The set of samples for model calibration provided interpretable spectra over the adjusted fingerprint region (925–1650 cm−1), which contains a selected number of bands that are indicative of the presence of the main chemical components of ...
