A Parameter Estimation Method of DC-link Capacitor Based on Pre-charge Process of Traction Converter
As a key component of traction converter, DC-link capacitor plays a key role in stabilizing DC side voltage. However, when a DC-link capacitor is exposed to high temperature and high pressure for a long time, its equivalent series resistance(ESR) will ...

Reversible Tuning of Multiple Molecular Kinking for Stem Cell Regulation In Vivo
In this work, we introduce the novel concept of background component‐free “multiple kinks” material platform composed solely of liganded multiple kink‐bearing molecules as a strategy for dynamic biomaterial design. Tri‐kink molecules enable effective near‐infrared light‐triggered ligand masking and visible light‐triggered ligand exposure, thereby ...
