DOI: 10.1016/j.aca.2018.04.046

Abstract: Unsaturated lipids exhibit different physiological significances due to the different locations of the carbon-carbon double bond (C=C). Identifying lipid isomers with mass-based methods remains challenging. Xia's group has been successfully employed Paternò-Büchi (PB) reaction, a… read more here.

DOI: 10.1016/j.chemosphere.2021.129974

Abstract: The UV-filter benzophenone-3 (BP3) tends to associate with suspended sediment (SPS) due to hydrophobicity, which could alter its toxicological effects on non-target aquatic organisms. In this study, the freshwater cladoceran Daphnia magna (D. magna) was selected… read more here.
