Electrochemo-Mechanics insights of Sn foil anode in Sodium-Ion batteries.

The development of high-performance sodium-ion batteries (SIBs) is crucial to meeting the growing demand for low-cost, sustainable energy storage alternatives to lithium-ion batteries (LIBs). However, achieving stable cycling performance in SIBs is challenging, particularly with tin (Sn) foil anodes, which suffer from issues like sodium trapping and structural degradation due to significant volume changes during sodiation and desodiation. In this study, we investigate the electrochemo-mechanical behavior of Sn foil anodes, focusing on the mechanisms of sodium trapping and structural evolution that impair battery performance.

[Dual interventional therapy for malignant gastroduodenal obstruction].

Background & Objective: The patients with malignant gastroduodenal obstruction usually have unresectable primary lesion and distant metastasis. Intra-luminal metallic stent implantation followed by intra-arterial chemotherapy via the tumor feeding arteries, so-called "dual interventional therapy", could temporarily relieve obstructive symptoms. This study was to evaluate the clinical safety and efficacy of dual interventional therapy on advanced malignant gastroduodenal obstruction.

[Intradiscal electrothermal treatment combined with epidural steroid injection for discogenic lumbago-leg pain].

Objective: To assess the effectiveness of intradiscal electrothermal treatment (IDET) combined with epidural steroid injection for discogenic lumbago-leg pain.

Methods: Fifty-nine patients with discogenic lower back pain and radical pain underwent IDET and CT guided spinal cord epidural steroid injection (Limethason). Thirty-eight patients with discogenic lower back pain and radical pain underwent IDET only.
