In Situ Buildup of Zinc Anode Protection Films with Natural Protein Additives for High-Performance Zinc Battery Cycling.

The uncontrolled growth of dendrites and serious side reactions, such as hydrogen evolution and corrosion, significantly hinder the industrial application and development of aqueous zinc-ion batteries (ZIBs). This article presents ovalbumin (OVA) as a multifunctional electrolyte additive for aqueous ZIBs. Experimental characterizations and theoretical calculations reveal that the OVA additive can replace the solvated sheath of recombinant hydrated Zn through the coordination water, preferentially adsorb on the surface of the Zn anode, and construct a high-quality self-healing protective film.

[Study on relationship between endogenous androgens and insulin resistance at the different stages of postmenopause].

Objective: To investigate the relationship between insulin resistance and endogenous androgens at early and late phase of postmenopause.

Methods: A total of 105 women with early postmenopause ( ≤ 5 years since menopause) and 107 women with late postmenopause ( ≥ 10 years since menopause) were enrolled in this study.In the mean time, those women were classified into normal weight[body mass index (BMI), BMI <24 kg/m(2)] group and overweight (BMI ≥ 24 kg/m(2)) group.
