For lithium-ion batteries, silicon monoxide is a potential anode material, but its application is limited by its relatively large irreversible capacity loss, which leads to its low initial Coulombic efficiency (ICE). In this study, we conduct a two-step reaction for the formation of silicon oxide-based materials, including a magnesiothermic reduction of SiO with Mg, followed by the solid-state lithiation of silicon oxide with LiCO. Our results demonstrate that Mg can reduce SiO to Si and form MgSiO, while LiCO reacts with SiO to form LiSiO.

Background: Opioid Agonist Treatment (OAT) is the most effective intervention for opioid use disorder (OUD), but retention has decreased due to increasingly potent drugs like fentanyl. This cohort can be used retrospectively to observe trends in service utilization, healthcare integration, healthcare costs and patient outcomes. It also facilitates the design of observational studies to mimic a prospective design.

Background: As survival following PD improved, long-term complications have emerged as an issue in current era. Pancreaticojejunostomy stenosis is the common long-term sequel after PD but rarely addressed. This study aimed to investigate the benefit of pancreatic duct stent in reducing PJ stenosis after PD.

In this study, a novel tunnel structure vanadate NaVO (NaVO) cathode for aqueous zinc ion batteries (AZIBs) is facilely fabricated by thermal decomposition of polyoxovanadate containing NH ions. The NaVO cathode is characterized by abundant oxygen vacancies and nanometer dimensions. These attributes can offer extra reaction sites and suppress structural collapse during circulation.

The practical applications of all-solid-state batteries (ASSBs) are hindered by poor Li kinetics in electrodes due to the inadequate contact between the cathode active materials (CAMs) and solid-state electrolytes (SSEs). Therefore, improving the contact interface between CAMs and SSEs is necessary to improve the cathodic Li kinetics by increasing the lithium-ion transport sites. To address this issue, sub-micrometer LiPSCl (SU-LPSC) particles of high specific areas were utilized to fabricate cathodes with high mass loading.
