Relationships between amylopectin internal molecular structure and physicochemical properties of starch

“…Como en el suavizado, la rutina de Savitzky-Golay también puede ser usada para calcular derivadas con buenos resultados. Los métodos derivados reducen la sensibilidad multivariante, lo que da lugar a una mayor incertidumbre para la estimación de la regresión y, en consecuencia, se generan errores de predicción altos (Rinnan et al, 2009;Siesler et al, 2006).…”

“…On the one hand, scattering correction methods (SNV and MSC) remove high-frequency noise, reduce multiplicative and additive effects of dispersion and particle size, and reduce differences in overall signal intensities. Derivatives, on the other hand, correct the spectrum by removing trends and highlighting peaks of interest (Siesler et al, 2006).…”

Development of NaY9Si6O26:Yb3+ phosphors with high thermal stability for NIR anti-counterfeiting: study of its crystal structure and luminescent properties

“…This type of radiation has promising potential for varied applications, mostly related to the characterization of chemicals, security, pharmaceutical, medical, cosmetic, food, and agricultural industries, which contribute to the continued advancement of modern technology. [1][2][3][4][5] Radiation sources such as tungsten halogen lamps, NIR light-emitting diodes (LEDs), and phosphor-converted LEDs (pc-LEDs) can emit in the infrared range. 6 However, the selection of these radiation sources for varied applications is based on the wavelength, full width at half maximum (FWHM), lifetime, efficiency, and thermal stability.…”

Determination of carvacrol content in Alaska yellow cedar (Callitropsis nootkatensis) extractives

“…Many wood-related studies have used NIR spectroscopy because it requires minimal sample preparation and is less sensitive to wood moisture content variations than FTIR spectroscopy (Siesler et al 2008). The NIR region ranges from 4000 cm -1 to 12500 cm -1 (2500 nm to 800 nm), with absorption bands resulting from overtones and combinations of C-O, O-H, C-H, and N-H bond vibrations (Siesler et al 2008).…”

Extractive analysis using NIR spectroscopy has been explored for mahogany, white oak, eucalyptus, larch, and poplar wood (Gierlinger and Wimmer 2004;Poke and Raymond 2006;Da Silva et al 2013;He and Hu 2013).…”
