A Promising Approach to Ultra-Flexible 1 Ah Lithium-Sulfur Batteries Using Oxygen-Functionalized Single-Walled Carbon Nanotubes.

Lithium-sulfur (Li-S) batteries represent a promising solution for achieving high energy densities exceeding 500 Wh kg, leveraging cathode materials with theoretical energy densities up to 2600 Wh kg. These batteries are also cost-effective, abundant, and environment-friendly. In this study, an innovative approach is proposed utilizing highly oxidized single-walled carbon nanotubes (Ox-SWCNTs) as a conductive fibrous scaffold and functional interlayer in sulfur cathodes and separators, respectively, to demonstrate large-area and ultra-flexible Li-S batteries with enhanced energy density.

Vertically Aligned Binder-Free TiO Nanotube Arrays Doped with Fe, S and Fe-S for Li-ion Batteries.

Vertically aligned Fe, S, and Fe-S doped anatase TiO nanotube arrays are prepared by an electrochemical anodization process using an organic electrolyte in which lactic acid is added as an additive. In the electrolyte, highly ordered TiO nanotube layers with greater thickness of 12 μm, inner diameter of approx. 90 nm and outer diameter of approx.

Cementless total hip arthroplasty in patients with osteonecrosis after kidney transplantation.

This study was to determine the mid- to long-term survivorship of cementless metal-on-metal THA in 52 patients (74 hips) who underwent THA for osteonecrosis of the femoral head with a cementless THA. The mean follow-up was 10.2 years.
