macrocarpa, and the functional group assignment is summarized in Table 2. The whole range of FTIR raw spectra looks very similar by observation because of the similarity in chemical composition. That is, significant relationship within the FTIR spectra and α-glucosidase inhibition was not detected ...

The particular “peak” of energy at a certain wavenumber can move around based on other chemical and matrix factors (as well as by the way the incident energy is introduced). Therefore we do not simply have a “look up” table to say what a particular band of energy will absolutely ...

Table 1.Source: Edinburgh Instruments FTIR provides a powerful tool for qualitative and quantitative analysis. When a plastic absorbs IR radiation, it produces a spectrum representative of its molecular “fingerprint”. Different plastic samples provide different fingerprints, which allows the identificatio...

There is evidence of considerable Cr(VI) in the rutile electrodes, relative to the basic ones, as shown in Table 2. However, there is uncertainty in the Cr(VI) due to the numerous digestion processes which are part of the sample preparation procedure (discussed earlier in the introduction se...
