From Disorder to Staging: Mechanism of Li-ion Diffusion in Graphite Revealed by Large-Scale Molecular Dynamics

Abstract Capturing the cross-layer kinetics of intercalants remains a fundamental bottleneck in understanding the structural evolution of layered host materials. This challenge is particularly critical in Li-ion batteries, where designing high-rate graphite anodes is hindered by...

Shape Optimization of a Tesla Valve-Type Control Valve Trim Flow Path Using Gaussian-Process-Regression-Based Bayesian Optimization

This study presents a shape optimization framework for a Tesla valve-type trim to improve cavitation suppression while satisfying target flow coefficient (C_v) requirements. A surrogate-model-based optimization loop was developed by integrating Computational Fluid Dynam...
