Experiments on Air Compression with an Isothermal Piston for Energy Storage
Energies, 2019 Air is usually compressed adiabatically in the compressor. As the operating speed of compressors can be several thousand rpm, heat generated during compression cannot be sufficiently transmitted to the environment in such a short time.

Advanced Science, EarlyView.This study explores the therapeutic potential of iNSC‐Exo via local and systemic delivery in TBI mice. It is found that iNSC‐Exo enhances NRXN signaling through Microglia_Nrg3 and Microglia_Rarb, effectively promoting functional and neurological recovery, suggesting a new therapeutic strategy for TBI. Abstract Traumatic brain injury (TBI) poses serious

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 ...

Subvoxel Control of Fiber Orientation via Multidirectional Shearing in 3D Printing
Advanced Science, EarlyView.A novel 3D printing technique enables subvoxel control of fiber orientation in all three directions through multidirectional shearing using nozzle rotation and inclination. It allows localized and tunable mechanical and thermal responses through programmable microstructures within a strand.

Electromagnetic Casimir piston in higher dimensional spacetimes
, 2011 We consider the Casimir effect of the electromagnetic field in a higher dimensional spacetime of the form $M\times \mathcal{N}$, where $M$ is the 4-dimensional Minkowski spacetime and $\mathcal{N}$ is an $n$-dimensional compact manifold.
