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

The Annals of Family Medicine, 2011 Many problems can be solved through following clinical guidelines and algorithms. In this essay, however, I explore the importance of narrative by connecting an ancient Middle Eastern teaching fable to a contemporary story of healing. A middle-aged Latina, Magdalena, comes to my residency clinic with chronic hypertension, cerebrovascular disease, and ...
