Characterization of the medium infrared spectra of polyphenols of red and white wines by integrating FT IR and UV–Vis spectral data
2021, LWTCitation Excerpt :Spectra were acquired in triplicate. Assignment of MIR peaks to polyphenols functional groups was performed with the aid of literature reports (Gorinstein et al., 1993; Edelman et al., 2001; Tarantilis, Troianou, Pappas, Kotseridis, & Polissiou, 2008; Agatonovic-Kustrin, Morton, & Yusof, 2013; Ricci, Olejar, Parpinello, Kilmartin, & Versari, 2015; dos Santos G rasel, Ferrão, & Wolf, 2016). The FT-IR spectral region in the range 1750–950 cm−1 was digitized to 451 data points while the UV–Vis spectra in the range 240–650 nm (Sanna et al., 2014) to 409 spectral data.
Fabrication and modification of homemade paper-based electrode systems
2021, TalantaCitation Excerpt :The results for poly(AP) and poly(ABA) were similar. The characteristic functional group of phenol is hydroxyl (–OH) [38], but its presence in poly(phenol) is expected to be small accounting the chemical change promoted by polymerization. This was indeed confirmed in the FTIR spectra (Figure S3, Supplementary Information).
Simulating the protective role of bark proanthocyanidins in surface coatings: Unexpected beneficial photo-stabilisation of exposed timber surfaces
2017, Progress in Organic CoatingsCitation Excerpt :Both condensed tannins and catechin, the monomeric flavonoid unit of proanthocyanidin condensed tannins (Fig. 1), have a broad UV absorption, exhibiting UVB characteristics (280–315 nm), with an absorption peak at 275 nm and broad absorbance extending <250 nm [2]. The type of inter- and intra-flavanyl linkages found within condensed tannins define the maxima and absorbance shifts of the 275 nm peak [20–22]. It was also found alkalinity can further complicate this absorption profile with higher pH both broadening and shifting this peak to higher wavelength as a result of phenolate ion formation and resonance effects.
Bioinspired reduced graphene oxide nanosheets using Terminalia chebula seeds extract
2015, Spectrochimica Acta - Part A: Molecular and Biomolecular SpectroscopyCitation Excerpt :For instance, our T. chebula extract reduced graphene oxide showed an absorption peak at 275 nm, which is higher than that of hydrazine [34] and phenyl hydrazine [35] reduced graphene (270 nm), indicating the efficient reducing ability of polyphenols present in T. chebula extracts. The typical broad shoulder appeared at 367 nm may be due to the presence of polyphenols that are attached on the surface of graphene nanosheets which prevents agglomeration of graphene [36,37]. Further, Fourier transform infrared (FTIR) spectroscopic studies of pure GO and TC reduced GO samples were performed to know the extent of reduction (Fig. 3).
