TL;DR: NIR spectroscopy in conjunction with chemometrics, is a very useful and rapid technique for the discrimination of jujube fruit.

Journal ArticleDOI
TL;DR: Both spectroscopic techniques demonstrate that there are similar but less spectral changes of BSA for the trypsin attack than for α-chymotrypsin although the substrate/enzyme ratio is taken the same.

Journal ArticleDOI
TL;DR: Detailed analysis of intrinsic defect structure of ZnO was given with respect to mean particle size and calculation of band gap energies revealed consistent results with the experimental observations.

Journal ArticleDOI
TL;DR: A statistically good agreement was found between the amounts of paracetamol determined using PLS and GA-PLS algorithms, and that obtained by UHPLC analysis, whereas for tramadol results were proven to be more reliable compared to those of PLS.
