GaN nanorods/N–doped carbon derived from Ga–MIL–68 as a separator coating for suppressing the shuttle effect in lithium–sulfur batteries

Lithium–sulfur batteries (LSBs) offer high theoretical energy density, yet their practical deployment is constrained by lithium polysulfide (LiPS) shuttling, sluggish sulfur redox kinetics, and unstable lithium deposition. This work addresses whether a single separator coating ca...

Green Production Modes in Platform Supply Chains Under Eco-Label Policies: A Cost Structure Perspective

This study investigates how heterogeneous green production modes affect operational decisions and welfare outcomes in platform-based supply chains under eco-label policies. We develop a model consisting of a manufacturer and a platform, in which the government sets a product gree...

Research of bearing fault diagnosis methods based on persistent homology

The persistent homology method is a recent big data analysis tool that can not only explore the nonlinear structure of high-dimensional complex data but also discover the shape of the data. In this article, a sliding window method is used to construct point clouds from Case Weste...
