TL;DR: During 1 year of storage monomeric anthocyanins declined almost tenfold, probably due to polymerization reactions and copigmentation, while the concentration of total phenols and all metals remained practically constant.

TL;DR: In this article, the spatial and temporal variability for the particulate matter (PM) concentration mass and water-soluble ionic species concentrations for the investigated sites were studied, and the average size distributions of the mass and individual ions at the suburban site (NCSR Demokritos) showed a bimodal size distribution.

TL;DR: In this article, the optimization of scandium extraction from bauxite residue with sulfuric acid is investigated using Taguchi methodology, where acid molarity, leaching time, solid/liquid ratio, and reaction temperature were selected as control parameters for the selective scandiam recovery.

TL;DR: In this article, an optimized leaching condition set for scandium recovery, using the most advantageous option of sulfuric acid, was investigated, and a leaching scale-up process to be established in the premises of Mytilineos S.A. (formerly Aluminium of Greece, the largest Greek alumina and aluminum producer), taking into account the feed requirements of a subsequent advanced ion exchanged procedure.

TL;DR: In this paper, the authors investigated a Scandium (Sc)-selective leaching process of Bauxite Residue (BR), where a set of process design aspects have been investigated.
