Chemical Reactivity Properties, Solubilities, and Bioactivity Scores of Some Pigments Derived from Carotenoids of Marine Origin through Conceptual DFT Descriptors by Norma Flores-Holguín, Juan Frau, Daniel Glossman-Mitnik

“…All the chemical reactivity descriptors for the systems were calculated via conceptual density functional theory (CDFT). Finally, the potential bioavailability and druggability as well as the bioactivity scores for the marine carotenoid pigments were predicted through different methodologies already reported in the literature, which have been previously validated during the study of other natural products obtained from marine sources.…”

Prediction of a New Phase of CuxS near Stoichiometric Composition by Prashant Khatri, Muhammad N. Huda

“…In this paper, we have predicted a new crystal phase of copper sulfide (CuxS) around chemical composition of x=1.98 by utilizing crystal database search and density functional theory. We have shown that this new crystal phase of CuxS is more favorable than low chalcocite structure even at stoichiometric composition of x=2. …”
