Weissella cibaria SGW054 alleviates neurodegenerative progression in Proteus mirabilis- and 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine-induced Parkinson's disease mice by regulating gut microbiota dysbiosis.

Emerging evidence suggests that gut microbiota dysbiosis contributes to the initial stages of neuroinflammation and dopaminergic neurodegeneration in Parkinson's disease (PD). Probiotics are receiving attention as a treatment for PD because they restore gut microbiota balance and brain homeostasis. In this study, we demonstrated that Weissella cibaria SGW054 (SGW054), a probiotic strain, exhibited antibacterial activity against Proteus mirabilis (PM), which induces PD pathology.

Overcoming Challenges in Silicon Anodes: The Role of Electrolyte Additives and Solid-State Electrolytes.

Silicon-based anodes have emerged as promising candidates for advanced lithium-ion batteries (LIBs) owing to their outstanding lithium storage capacity; however, the commercial implementation of silicon-based anodes is hindered primarily by their significant volumetric changes and the resulting solid electrolyte interphase (SEI) instability during the lithiation/delithiation process. To overcome these issues, electrolyte optimization, particularly through the use of functional additives and solid-state electrolytes, has attracted significant research attention. In this paper, we review the recent developments in electrolyte additives, such as vinylene carbonate, fluoroethylene carbonate, and silane-based additives, and new additives, such as dimethylacetamide, that improve the SEI stability and overall electrochemical performance of silicon-based anodes.

Strategies for Enhancing the Stability of Lithium Metal Anodes in Solid-State Electrolytes.

The current commercially used anode material, graphite, has a theoretical capacity of only 372 mAh/g, leading to a relatively low energy density. Lithium (Li) metal is a promising candidate as an anode for enhancing energy density; however, challenges related to safety and performance arise due to Li's dendritic growth, which needs to be addressed. Owing to these critical issues in Li metal batteries, all-solid-state lithium-ion batteries (ASSLIBs) have attracted considerable interest due to their superior energy density and enhanced safety features.
