Advanced Materials, EarlyView.This study demonstrates the combination of magnetic nanoparticles and functional blowing agents into supraparticles. Upon induction heating, they actuate via rapid gas generation or extensive volume expansion. These supraparticles lift up to 25 000 times their own mass and rapidly open cured epoxy resins, providing a versatile strategy for fast micron ...

Advanced Materials, EarlyView.A solid‐state ionic actuator integrates sensing, actuation, and memory within one material. A brief UV pulse induces long‐lasting deformation via coupled network rearrangement, dehydration, and rehydration, while ionic redistribution enables self‐powered sensing, supporting multifunctional, energy‐efficient soft robotic functions without continuous ...

Engineering Applications of Computational Fluid MechanicsWhen pump-turbines operate under off-design conditions, complex internal vortex flows often arise, leading to hydraulic instabilities and increased energy losses. Traditional hydraulic loss evaluation methods fail to quantitatively link vortex structures

Nonplanar Bouligand Architectures for Enhanced Mechanical Performance in Cementitious Composites
Advanced Materials, EarlyView.Inspired by the impact region of the Mantis shrimp dactyl club, nonplanar additive manufacturing translates sinusoidal Bouligand architectures into cementitious composites. Printing‐induced anisotropy and architected interfaces promote distributed damage and arrest crack propagation, enhancing strength and energy absorption.

Записки Горного института, 2023 In the steady state of operation, the temperature of a mining excavator hydraulic fluid is determined by the ambient temperature, hydraulic system design, and power losses. The amount of the hydraulic system power loss depends on the hydraulic fluid physical and thermodynamic properties and the degree of wear of the mining excavator hydraulic system ...
