All-solid-state batteries using Si as the anode have shown promising performance without continual solid-electrolyte interface (SEI) growth. However, the first cycle irreversible capacity loss yields low initial Coulombic efficiency (ICE) of Si, limiting the energy density. To address this, we adopt a prelithiation strategy to increase ICE and conductivity of all-solid-state Si cells.

All-solid-state batteries have recently gained considerable attention due to their potential improvements in safety, energy density, and cycle-life compared to conventional liquid electrolyte batteries. Sodium all-solid-state batteries also offer the potential to eliminate costly materials containing lithium, nickel, and cobalt, making them ideal for emerging grid energy storage applications. However, significant work is required to understand the persisting limitations and long-term cyclability of Na all-solid-state-based batteries.

Article Synopsis
  • Mitral annular disjunction (MAD) is a common structural abnormality found in some patients undergoing mitral valve surgery, notably linked to mitral valve prolapse and myxomatous disease.
  • In a study of 185 patients who had mitral valve surgery, 32.4% were found to have MAD, but the majority saw this condition corrected by surgery, with only 3.9% still showing MAD afterward.
  • The results indicated that having MAD did not lead to higher rates of post-operative complications like mitral regurgitation, arrhythmias, or other major cardiovascular events compared to those without MAD.

Pancreatic ductal adenocarcinoma (PDAC) is the deadliest of the common cancers. A major hallmark of PDAC is an abundant and dense fibrotic stroma, the result of a disproportionate deposition of extracellular matrix (ECM) proteins. Cancer-associated fibroblasts (CAFs) are the main mediators of PDAC desmoplasia.

Importance: Transcatheter aortic valve implantation (TAVI) is a less invasive alternative to surgical aortic valve replacement and is the treatment of choice for patients at high operative risk. The role of TAVI in patients at lower risk is unclear.

Objective: To determine whether TAVI is noninferior to surgery in patients at moderately increased operative risk.
