Rapid Fabrication of Self‐Propelled and Steerable Magnetic Microcatheters for Precision Medicine

Advanced Materials, EarlyView.
A rapid Joule heating fabrication method for the production of self‐propelling, adaptive microcatheters, with tunable stiffness and integrated microfluidic channels is presented. Demonstrated through three microrobotic designs, including a steerable guiding catheter, an untethered wave‐crawling TubeBot, and a distal‐end propelled microcatheter, it was ...

Visual information transmission to navigators for the navigation safety

Journal of Light & Visual Environment, 1977
For the navigators during coastal navigation at night, signal lights such as the navigational aids and the navigation lights of other ships should have a good visual transmission from the view point of navigation safety. In this paper the relation between the recognition of the signal and background lights is described.

Adaptive fixed-time dynamic surface path following control for underactuated ships with input delay

International Journal of Naval Architecture and Ocean Engineering
This paper proposes a novel fixed-time path-following control strategy for underactuated ships with input delay. Firstly, the fractional power is employed in the controller design to obtain the fast system convergence.

A Nano‐Interception Strategy for Chronic Heart Failure: Prussian Blue Nanoparticles Disrupt Fibroblast‐Immune Communication via CCL2 Sequestration

Advanced Materials, EarlyView.
A nano‐interception strategy disrupts pathogenic fibroblast–macrophage crosstalk in chronic heart failure. Scalable Prussian blue nanoparticles selectively sequester CCL2 via ultrahigh‐affinity binding, preventing CCR2+ macrophage recruitment and breaking a key fibro‐inflammatory circuit. This approach demonstrates robust efficacy in murine and porcine
