Correlation between the Microstructure of the Carbon Protective Layer and Cycle Performance of Anode-Free All-Solid-State Lithium-Ion Batteries.

Anode-free all-solid-state lithium-ion batteries (ASSBs) are among the most promising energy storage devices owing to their high energy density and safety. Protective layers, such as the Ag-C composite layer, are essential for suppressing unwanted reactions between electrodeposited Li metal and the solid-state electrolyte, thereby ensuring highly cyclable ASSBs. Although recent research efforts have focused on the composition and microstructure of carbon-based protective layers, there are a few reports on the relationship between the microstructure of carbon-based protective layers and the cycling performance of ASSBs, particularly when the pore size of the carbon layers is within the size criterion for Li Coble creep.

Robotic surgeries in pediatric patients: an early experience in a single center.

Purpose: Robotic surgery (RS) has the advantages of 3-dimensional view, optical magnification, motional scaling, and improved ergonomics and degree of freedom. Although RS has widely been performed on pediatric patients lately, there are still numerous restrictions and ambiguous indications. The purpose of this study was to report our early experience with RS on pediatric patients at a single center.

Cervical spondylotic myelopathy caused by violent motor tics in a child with Tourette syndrome.

Introduction: We report a case of a 9-year-old boy with Tourette syndrome (TS) who developed progressive quadriparesis that was more severe in the upper extremities.

Case Report: He had experienced frequent and violent motor tics consisting of hyperflexion and hyperextension for years. Magnetic resonance imaging (MRI) revealed a focal high-signal intensity cord lesion and adjacent cervical spondylotic changes.
