Efficacy of Information-Motivation-Behavioral Skills ModelBased nursing care intervention in management of patients with Heart Failure: A retrospective cohort study.

Objective: Self-care practices are integral part of heart failure (HF) management. Information-Motivation-Behavioral skills (IMB) model has shown promise in fostering better self-care behaviors, but its efficacy in management of HF patients remains underexplored. This retrospective study investigated the value of IMB model-based nursing intervention for improving self-care, hemodynamic indicators, and quality of life (QOL) of HF patients.

NiSn/nitrogen-doped graphene composite with chemisorption and electrocatalysis as advanced separator modifying material for lithium sulfur batteries.

Lithium-sulfur batteries have been widely studied because of their advantages of abundant reserves, environmental friendliness, low cost andhighspecific capacity. However, the volume expansionand the low electrical conductivity of sulfur, and the shuttle effect of polysulfides limit their application. Herein,wesynthesizea two-dimensional layered NiSn/nitrogen-doped graphene (NG) composite asseparator modifying material for lithium-sulfur batteries.
