2011. Application of Fourier Transform Infrared Spectroscopy (FTIR) for assessing biogenic silica sample purity in geochemical analyses and palaeoenvironmental research. Climate of The Past 7: 65-74.G. E. A. Swann and S. V. Patwardhan, "Application of Fourier Transform Infrared Spectroscopy (...
PA-FTIRspectra of powdered silica, clay and talc show that silica and clay have vibrational bands near 1100 [cm.sup.-1]. To confirm the polymer structure in the two OTR tire treads,PA-FTIRspectra were obtained for two cured carbon black-filled compounds having a blend of NR and cis-1,...
The USY-550-700 final sample is used for FTIR Spectra of adsorbed pyridine to study the type of acidity produced on the sample prepared. This sample is also tested in the chemical reaction as a catalyst to study the effect of acidity developed on it in the chemical reaction. The study of...
A reinterpretation of the EPR spectra of Cu(II) in zeolites A, Y and ZK4, based on ab initio cluster model calculations A theoretical study is presented of the EPR spectra of the dehydrated Cu(II)-A, Cu(II)-Y and Cu(II)-ZK4 zeolites. B3LYP-DFT geometry optimizations were per... K...
The first is that relatively high concentrations are needed to obtain spectra of reasonable quality39,87. This is due to the low affinity of protein for the ATR crystal surface, as the result of electrostatic repulsion between BSA and ZnSe and the weakly hydrophobic nature of the ZnSe ...
The protein infrared spectra were enhanced using Fourier self-deconvolution, and spectral changes during adsorption were interpreted in terms of protein conformation changes. An increase in the β-structure content of fibronectin and fibrinogen was observed upon adsorption. 展开 ...
The spectra are corrected for the background and are normalized based on the OH-bending peak. (b) Relative peak intensity ratio of the water stretching and bending bands as a function of pillar height for hydrophilic (UV/O3-treated, Wenzel state) and superhydrophobic (FDTS-coated, Cassie-...

Fig. 1. Diffuse reflectance infrared Fourier transform spectra of a high organic matter soil (120 g C kg− 1 soil) across a range of KBr dilution. The most recent FTIR technique for soil analysis is attenuated total reflectance Fourier transform infrared spectroscopy (ATR-FTIR), unique in th...
Finally, the remaining quantities of the above samples was sent for FTIR, as discussed in the following sections. FTIR spectra using the ATR - Fig. 2 shows the FTIR analysis of welding fumes generated and collected during the MMA welding process, which at first glance shows higher intensities ...
