Aqueous zinc-ion batteries (AZIBs) have become an ideal candidate for large-scale energy storage systems owing to their inherent safety and highly competitive capacity. However, severe dendrite growth and side reactions on the surface of zinc metal anodes lead to quick performance deterioration, seriously impeding the commercialization of AZIBs. In this work, a self-regulated zinc metal/electrolyte interface is constructed to solve these problems by incorporating the trivalent Gd additive with a lower effective reduction potential into the aqueous ZnSO electrolyte.

Objective: To study the efficiency of surgical treatment on coarctation of the aorta and associated with heart defect.
Methods: From 1994 to 2001, 45 patients with aortic coarctation and associated with heart defect underwent surgical repair. They were divided into two groups: single-stage repair group (26 cases) and two-stage repair group (19 cases).
