The Reconstruction Mechanism and NH 3 ‐SCR Kinetics of Mn Clusters on MoS 2 by Ab Initio Data Driven Machine Learning Simulations

Ziyi Wang, Luneng Zhao, Yuan Chang, Chunqiang Zhuang et autres

ABSTRACT The strong metal‐support interactions (SMSI) between supported clusters and substrate can drive the local structure reconstructions, which stabilize the supported clusters to avoid migration and aggregation. Such reconstruction and stabilization mechanism are crucial to construct the atomically dispersed catalysts (ADCs), but …

Leader-Follower Platooning Using Infrared Proximity Sensing Without Communication

Chenghang Liu, Yuan Chang, Wei Yan, Quan Zhang et autres

This paper investigates to what extent leaderfollower formation control can be advanced on a resourceconstrained mobile robot platform, using only low-cost, saturated infrared collision sensors and without allowing vehicle-to-vehicle communication or external positioning. We implemented a twovehicle leader-follower system on the Pololu …
