A Parameter Estimation Method of DC-link Capacitor Based on Pre-charge Process of Traction Converter

open access: yesKongzhi Yu Xinxi Jishu, 2023
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

open access: yesAdvanced Functional Materials, EarlyView.
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 ...
