The time course of the observed FTIR measurements during retrogradation of waxy maize starch is very similar to those produced from other techniques, such as shear modulus. This process can also be in wheat starch gels and the possibility that it can be measured in real foodstuffs is ...
The Fourier transform infrared (FTIR) spectrum demonstrated that the stretching vibration peak for the carbonyl group (C=O) in EGCG shifted from 1691 cm−1 to 1640 cm−1 in MPN@DP-PCs, indicating the presence of strong hydrogen bonds between the EGCG ligands and the PC templates (...
catalyst was characterized by Inductively coupled plasma (ICP), transmission electron microscopy (TEM), scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), energy-dispersive X-ray spectrum (EDS), vibrating sample magnetometer (VSM) and Fourier transform infrared (FTIR) analysis...
mesochannels within the DP-PCs were fully filled with MPNs. The Fourier transform infrared (FTIR) spectrum demonstrated that the stretching vibration peak for the carbonyl group (C=O) in EGCG shifted from 1691 cm−1to 1640 cm−1in MPN@DP-PCs, indicating the presence of strong ...

FT-IR spectroscopy is often used to classify structures because functional groups generate characteristic bands in terms of both the intensity and location (i.e., frequency). The position of a large number of characteristic bands are known and tabulated in the FTIR library [71]. Fourier transform...
