Galvanic stabilization of Zn metals for long-life aqueous batteries.

Rechargeable aqueous Zn-ion batteries have received extensive attention due to their environmental friendliness, high safety, and low cost. However, the Zn dendrite growth during plating/stripping cycles, which deteriorates coulombic efficiency and shortens the cycle life, dramatically hinders the application of Zn anodes in batteries. Herein, we propose to grow an In layer on Zn foils through spontaneous Galvanic reaction to address the challenging Zn dendrites.

Experiences, Perspectives, and Barriers to Physical Activity Parenting Practices for Chinese Early Adolescents.

Background: Parents play an important role in shaping youth's lifestyle behaviors. This study aimed to investigate physical activity parenting practices (PAPP) for Chinese early adolescents and compare reporting discrepancies between parents and adolescent boys and girls.

Methods: Fifty-five adolescent-parent dyads participated in 16 paired focus group interviews, and an additional 122 dyads completed questionnaire surveys with open-ended questions.
