Rational design of MXene@TiO nanoarray enabling dual lithium polysulfide chemisorption towards high-performance lithium-sulfur batteries.

Lithium-sulfur (Li-S) batteries face a few vital issues, including poor conductivity, severe volume expansion/contraction, and especially the detrimental shuttle effect during the long-term electrochemical process. Herein, we designed a hierarchical MXene@TiO2 nanoarray via in situ solvothermal strategies followed by heat treatment. The MXene@TiO2 heterostructure achieves superior charge transfer and sulfur encapsulation.

A Novel Intelligent Vascular Stent: Preparation and Characterization of Hydrophobic Steel Mesh Stent with Liquid Surface Tension Response.

An intelligent vascular stent was fabricated from a hydrophobic mesh tube, which cans in-situ release thrombolytic drugs only by an injection of nitroglycerin solution. The mesh with 80# pore size has the highest hydrophobic property and the most sensitive response performance after 3.00 wt% (Heptadecafluoro-1,1,2,2,-tetradecyl)trimethoxysilane (HFTES) treatment.
