The mediating role of sleep quality in the relationship between social support and depressive symptoms in early pregnant women.

Objective: To explore the mediating effect of sleep quality between social support and depressive symptoms in pregnant woman at the early pregnancy stage.

Methods: Pittsburgh sleep quality index (PSQI), social support revalued scale (SSRS), and self-rating depression scale (SDS) were used to investigate the sleep quality, social support status and depression of 269 pregnant women in early pregnancy in Guangxi Zhuang Autonomous Region Maternal and Child Health Hospital from July 2022 to December 2022. Pearson correlation analyses and Bootstrap were used to test the correlation and mediating effect between variables.

Regulating the Solvation Shell Structure of Lithium Ions for Smooth Li Metal Deposition in Quasi-Solid-State Batteries.

Gel polymer electrolytes (GPE) are promising next-generation electrolytes for high-energy batteries, combining the multiple advantages of liquid and all-solid-state electrolytes. Herein, we a synthesized GPE using poly(ethylene glycol)acrylate (PEGDA) in order to understand how the GPE efficiently inhibits lithium dendrite formation and growth. The effects of PEGDA on the solvation shell structure of the lithium ion are investigated using density functional theory (DFT) and ab initio molecular dynamics (AIMD) simulations, which are also supported by Raman spectroscopy.
