Extraction and characterization of chitin and chitosan with antimicrobial and antioxidant activities from cosmopolitan Orthoptera species (Insecta) (2015, background): “When the FTIR spectra of the grasshopper chitosan preparations were examined, amide I (C=O-NHR) and amine group (-NH2) bands, which are characteristic of chitosan, were found at 1654/cm [41,42] and 1590 cm [41-44], respectively.”
New chitin, chitosan, and O-carboxymethyl chitosan sources from resting eggs of Daphnia longispina (Crustacea); with physicochemical characterization, and antimicrobial and antioxidant activities (2014, unknown): “longispina were 1654/cm [40,41] and 1594/cm [40-43], respectively.”
Kenaf fiber reinforced composites: A review (2011, background): “From the DSC scan, several crucial parameters could be estimated, such as the glass transition temperature (Tg), melting temperature, crystalline level, and oxidation [59].”
Application of Spectroscopic Methods for Structural Analysis of Chitin and Chitosan (2010, background): “Among the postulated internal reference bands are the OH stretching band at 3450 cm [125,133], the C-H stretching band at 2870–2880 cm [134], the –CH2 bending centred at 1420 cm [129], the amide III band at 1315–1320 cm [135], the anti-symmetric stretching of the C-O-C bridge at around 1160 cm [136]”
