Lithium-sulfur (Li-S) batteries demonstrate great potential for next-generation electrochemical energy storage systems because of their high specific energy and low-cost materials. However, the shuttling behavior and slow kinetics of intermediate polysulfide (PS) conversion pose a major obstacle to the practical application of Li-S batteries. Herein, CrP within a porous nanopolyhedron architecture derived from a metal-organic framework (CrP@MOF) is developed as a highly efficient nanocatalyst and S host to address these issues.

Background: Gastric cancer is one of the major malignant tumors in the world. Integrins expressed in cancer cells can promote tumor progression and migration. MiRNAs can inhibit the expression of target genes by directly binding to their mRNAs and can affect various important biological processes.
