Numerical Investigation of Coupled-Attitude Aerodynamic Characteristics of a Frigatebird-Inspired Wing in Marine Atmospheric Updrafts

Yanru Chen, Ran Liu, Yanling Miao, Guangyuan Liu et autres

Frigatebirds achieve exceptional long-endurance flight by efficiently utilizing marine atmospheric updrafts, offering a valuable biological prototype for low-energy bionic aircraft. Most existing studies focus on uniform inflow and single-axis attitudes, lacking systematic analysis of coupled-attitude aerodynamics and flow-field mechanisms in updraft environments. …

Homogenized Phosphonate‐Functionalized Fullerenes for Enhanced Electron Extraction in Perovskite Solar Cells

Yanxia Lin, Yanbiao Pan, Ajuan Fan, Juan Xia et autres

Abstract Pristine fullerene C 60 has been widely applied as an electron extractor in state‐of‐the‐art perovskite solar cells (PSCs); however, its poor solubility, arising from its strong tendency to aggregate in solution, limits its applicability. In parallel, the weak perovskite–C 60 interaction …
