Among all the measured functional groups, it was clearly seen that the intensities of IR peaks related to silicate, silica, kaolinite, and calcium carbonate were associated with the increased mass concentrations during the impact period. The observed IR peaks at 1,030 and 800cm 1 for silicate ...

It was concluded that the rigid and ordered structure of the cellulose was deteriorated by the superfine grinding treatment. XRD revealed that as the powder size decreased, the crystallinity and intensity of crystal peaks increased. The results of SEM showed that the superfine pulverizing was ...
However, absorption peaks of multiple functional groups usually coexist, resulting in the overlapping of characteristic peaks. This phenomenon makes it challenging to analyze and characterize the composition and structure of DOM accurately. Thus, it is only used for the qualitative analysis of DOM. ...
The x-axis—or horizontal axis—represents the infrared spectrum, which plots the intensity of infrared spectra. The peaks, which are also called absorbance bands, correspond with the various vibrations of the sample’s atoms when it’s exposed to the infrared region of the electromagnetic spectrum...
Results As expected, peaks corresponding to functional groups within nucleic acids, phospholipids, polysaccharides, proteins and lipids are observable in the FTIR spectra of bone tissues (Fig. 1). The peak positions along with their maximum absorbance for the average FTIR spectra with corresponding ...
Between 50 and 150 °C, the m/z 17 and 18 ion intensities indicate the presence of traces of water. Evaluation of the TGA curve yields a mass loss of about 0.2%. During the second mass loss step (1.8%), peaks are observed in the m/z 15, 16, 17, 18 ion curves. These peaks ...
