Tsallis and Kaniadakis Gaussian functions applied to the analysis of the Raman spectrum of diamond

, 2023
Previous studies (Sparavigna, 2023) have demonstrated the Tsallis q-Gaussian functions suitable for the analysis of Raman spectra. Besides the q-Gaussian, another generalized Gaussian form can be investigated for Raman spectroscopy; it is the Kaniadakis κ-Gaussian probability density function, which contains the κ-exponential. Here, we consider both q-

Biodegradable starch-based films containing saturated fatty acids: thermal, infrared and raman spectroscopic characterization

Polímeros
Biodegradable films of thermoplastic starch and poly (butylene adipate co-terephthalate) (PBAT) containing fatty acids were characterized thermally and with infrared and Raman spectroscopies. The symmetrical character of the benzene ring in PBAT provided
