Continuous Extrusion Forming Technology of Magnesium Alloy Thin-Walled Tubules.

This paper proposes a new technology of superimposed billet extrusion-forming for thin-walled magnesium alloy tubes. This process represents an improvement over the current technology, which suffers from low production efficiency, poor forming accuracy, and low material utilization. We developed a detailed forming process and mold structure, in which the excess material of the front billet is extruded out of the mold as the rear billet pushes on the front one.

The pyroptosis mechanism of ototoxicity caused by unconjugated bilirubin in neonatal hyperbilirubinemia.

When activated by unconjugated bilirubin (UCB), inflammatory mediators such as IL - 18 and TNF contribute to the neurotoxicity and ototoxicity observed in severe neonatal hyperbilirubinemia. However, in cell and molecular level, the regulation and mechanism of UCB-induced ototoxicity are remained unclear. In this study, 7-day-old mammary rats were exposed to various concentrations of UCB to imitate the infant auditory damage.

Enhancing Performance of CdS Quantum Dot-Sensitized Solar Cells by Two-Dimensional g-CN Modified TiO Nanorods.

In present work, two-dimensional g-CN was used to modify TiO nanorod array photoanodes for CdS quantum dot-sensitized solar cells (QDSSCs), and the improved cell performances were reported. Single crystal TiO nanorods are prepared by hydrothermal method on transparent conductive glass and spin-coated with g-CN. CdS quantum dots were deposited on the g-CN modified TiO photoanodes via successive ionic layer adsorption and reaction method.

Plasma-induced, nitrogen-doped graphene-based aerogels for high-performance supercapacitors.

Commonly used energy storage devices include stacked layers of active materials on two-dimensional sheets, and the limited specific surface area restricts the further development of energy storage. Three-dimensional (3D) structures with high specific surface areas would improve device performance. Herein, we present a novel procedure to fabricate macroscopic, high-quality, nitrogen-doped, 3D graphene/nanoparticle aerogels.
