Advanced Materials, Volume 37, Issue 13, April 2, 2025.A type of magnetically responsive artificial cells (ACs) has been developed, demonstrating the loading of mitochondria and self‐enclosure processes to ensure the protection of mitochondrial transport via the bloodstream. The treatment with ACs effectively transplanted mitochondria around the lesion, thereby improving neurological recovery by supporting

Swirl in a Four-Stroke Cycle Engine Cylinder
Bulletin of JSME, 1978 Air swirl speeds were measured in a motoring and firing run of a direct injection diesel engine, and the results were compared with those in steady flow tests. Experimental results show that, during the combustion period, the swirl speed in the firing condition is almost the same as that in motoring.

Recent Advances in Collective Behaviors of Micro/Nanomotor Swarms
Advanced Materials, EarlyView.This review describes the driving forces behind collective motion, explores the self‐organization of micro/nano swarms across zero‐dimensional (0D), one‐dimensional (1D), two‐dimensional (2D), and three‐dimensional (3D) spaces, and highlights their potential in drug delivery, environmental monitoring, and smart devices.

Quantum Lubrication: Suppression of Friction in a First Principle Four Stroke Heat Engine
, 2005 A quantum model of a heat engine resembling the Otto cycle is employed to explore strategies to suppress frictional losses. These losses are caused by the inability of the engine's working medium to follow adiabatically the change in the Hamiltonian ...
