Prediction of total carotenoids, color, and moisture content of carrot slices during hot air drying using non-invasive hyperspectral imaging technique
(2022-02-04)
The objective of this paper was to evaluate the performance of Partial Least Square Regression (PLSR) model and to assess the statistical agreement between two different measurement techniques, that is, Vis–NIR hyperspectral imaging (HSI) and standard laboratory methods for quality evaluation of dried carrots throughout the hot-air drying process. Carrots at commercial maturity of 3.5 months after planting were harvested in two seasons (2017 and 2018) and dried in a convective hot air dryer at 50°C, 60°C, and 70°C. ...

Lanthanide Complexes (Ln=La, Nd, Dy) of Octaethyl propane-1,1,3,3-tetrayltetrakis(phosphonate): Multidentate Binding Competing with Monodentate DMSO Complexes
(2022-12-09)
The preparation of lanthanide nitrate complexes [Ln(NO₃)₃{L}]ₙ (Ln³+=La, Nd, Dy) supported by the octaethyl propane-1,1,3,3-tetrayltetrakis(phosphonate) (L) chelate ligand platform is presented. Re-crystallization of these compounds from DMSO/THF led to a complete replacement of the multidentate phosphonate ester ligand and the formation of exclusively DMSO-supported lanthanide nitrate species [Ln(NO₃)₃(DMSO)₄]. The relative basicity of a model phosphonate ester vs. DMSO is explored with theoretical means, pointing ...
