Article Synopsis
- The study focuses on improving the specific energy density of lithium-ion batteries (LIB) for electric vehicles by using optimization methods.
- Researchers utilized design experiments to assess key factors such as electrode thickness, porosity, and particle size affecting battery performance.
- By applying the progressive quadratic response surface method (PQRSM), they achieved a 56.8% increase in specific energy density and reduced polarization by 11.5% while ensuring that power density remained acceptable.
We have isolated a new prenylated chalcone from the roots of Sophora flavescens (Leguminosae). We determined that structure of this compound is 7,9,2',4'-tetrahydroxy-8-isopentenyl-5-methoxychalcone (1) on the basis of spectroscopic analysis (1D and 2D NMR data). Compound 1 exhibited potent cytotoxicity against human acute promyelocytic (HL60), mouse lymphocytic (L1210) and human histiocytic (U937) leukemia cells.
