The PCA obtained after the spectral optimization showed improved results (4 PCs; RMSECV: 0.029) and important differences in specific bands and regions (Fig. 2). It should be noted that the most divergent wavenumbers on each region were identified by plotting PC’s-loadings, acquiring information...
We show that pyrogenic aragonite has a unique signature that allows its identification in archaeological sediments and lime binders of unknown origin. Based on these results, we developed a new FTIR-based method to assess the integrity and degree of preservation of aragonite and calcite when they ...
The reaction kinetics of the three pseudo-components in each stage can be comprehensively understood by dividing the principal thermal degradation process (devolatilization stage) into three substages through the use of the peak fitting tool in Origin 2023. This methodology has been employed to analyze...
