Bioinspired Twisted Artificial Muscles with Enhanced Performance for Underwater Applications
Advanced Science, EarlyView.A climbing plant‐inspired twisted artificial muscle (TAM) with a braided configuration and seal‐inspired thermal insulation enables high‐performance underwater actuation. Enhanced deformation, reduced heat dissipation, and rapid motion are validated through a bionic ray that exhibits straight and turning motions.

Variations of the Energy of Free Particles in the pp-Wave Spacetimes
, 2018 We consider the action of exact plane gravitational waves, or pp-waves, on free particles. The analysis is carried out by investigating the variations of the geodesic trajectories of the particles, before and after the passage of the wave.

Advanced Science, EarlyView.The research introduces a three‐phase electrostatic (ES) clutch with variable mechanical impedance control, specifically designed to enable continuous and precise friction modulation, thereby reducing both force degradation and oscillatory motion. This method effectively resolves conventional ES clutch issues, such as residual charge accumulation and ...

Suppressing Interfacial Instability of Immiscible Liquid‐in‐Liquid Flow Using Magnetic Forces
Advanced Science, EarlyView.This paper investigates the magnetic stabilization of an immiscible inner liquid surrounded by a ferrofluid sheath. Suppressing instabilities and thermomagnetic manipulation of the inner liquid are shown. The results provide insight into Ferrohydrodynamic jet control for applications of industrial, pharmaceutical and physiological relevance.

Super Time‐Resolved Tomography
Advanced Science, EarlyView.A super time‐resolved tomography (STRT) approach is presented to reconstruct 4D X‐ray movies with an order‐of‐magnitude improvement in temporal resolution without sacrificing spatial resolution. By leveraging a physics‐informed deep learning algorithm that shares spatiotemporal features, STRT achieves high‐fidelity 3D reconstructions from sparse‐view ...
