A systematic UHPLC-Q-TOF-MS/MS-based strategy for analysis of chemical constituents and related in vivo metabolites of Buyang Huanwu decoction.

Ethnopharmacological Relevance: Buyang Huanwu Decoction (BYHWD), a traditional Chinese medicine, is one of the classic prescriptions for the treatment of ischemic stroke in clinical practice. It has the effects of tonifying qi, activating blood circulation, and promoting meridian circulation. However, its chemical analysis has not been clarified, which greatly hinders its further clinical application.

Stabilizing Li-Rich Layered Cathode Materials Using a LiCoMnO Spinel Nanolayer for Li-Ion Batteries.

Lithium-rich cathodes have excess lithium in the transition metal layer and exhibit an extremely high specific capacity and good energy density. However, they still have some disadvantages. Here, we propose LiCoMnO, a new nanolayer coating material with a spinel structure, to modify the surface of lithium cathode oxide (LiMnNiCoO) with a layered structure.
