Building Sustainable Saturated Fatty Acid-Zinc Interfacial Layer toward Ultra-Stable Zinc Metal Anodes.

The commercialization pace of aqueous zinc batteries (AZBs) is seriously limited due to the uncontrolled dendrite growth and severe corrosion reaction of the zinc anode. Herein, a universal and extendable saturated fatty acid-zinc interfacial layer strategy for modulating the interfacial redox process of zinc toward ultrastable Zn metal anodes is proposed. The in situ complexing of saturated fatty acid-zinc interphases could construct an extremely thin zinc compound layer with continuously constructed zincophilic sites which kinetically regulates Zn nucleation and deposition behaviors.

Varieties of Hope Among Family Caregivers of Patients With Lymphoma.

In this study, 16 family caregivers of patients with lymphoma were interviewed on their changing perceptions of hope. The changing process starts from diagnosis to the present treatment state. We found that the changing perception of hope can be divided into three stages: the stage of generalized hope focusing merely on treatment and passive hope focusing on harm-avoidance, the stage of specified hope and active hope aiming at comfort-seeking, and the stage of multifaceted hope.
