A series of rare-earth metal complexes stabilized by different amine bridged bis(phenolate) ligands were synthesized and well characterized. Their catalytic performances for the ring-opening polymerization of l-lactic acid O-carboxyanhydride (l-lacOCA) and l-lactide were explored. Sequential

This study analyzed the organic distribution characteristics of original and treated water and their impacts on drinking water quality using a conventional water treatment process in the typical water supply sources for towns in the southwest hilly area of China. The results showed that the water
