Zum Vorkommen von Cholesterin in Hosta undulata (Liliaceen)
CHIMIA, 1972 The free sterols from leaves of Hosta undulata (Liliaceae) contain cholesterol, stigmasterol, and sitosterol in a ratio of approximately 16:51:33. Traces of campesterol are probably also present.

Enhancing Low‐Temperature Performance of Sodium‐Ion Batteries via Anion‐Solvent Interactions
Advanced Functional Materials, EarlyView.DOL is introduced into electrolytes as a co‐solvent, increasing slat solubility, ion conductivity, and the de‐solvent process, and forming an anion‐rich solvent shell due to its high interaction with anion. With the above virtues, the batteries using this electrolyte exhibit excellent cycling stability at low temperatures. Abstract Sodium‐ion batteries
