Scalable Fabrication of Thermally Reconfigurable Ge Metasurfaces Using Stencil Lithography for Mid‐Infrared Molecular Fingerprinting

Advanced Functional Materials, EarlyView.
Scalable stencil lithography enables resist‐free fabrication of high‐index Ge metasurfaces for mid‐infrared molecular fingerprinting. Reversible thermo‐optic tuning provides post‐fabrication spectral control for precise resonance–vibration mode alignment, enabling enhanced molecular fingerprinting of microplastic particles.

Influence of End Structure on Electromagnetic Forces on End Winding of a 1550 MW Nuclear Generator

International Journal of Rotating Machinery, 2017
A 3D electromagnetic model of the end region of a 1550 MW nuclear generator is set up. The electromagnetic forces on the involute and nose parts of the end winding under a rated operation are obtained through the 3D time-step finite element method.

Magnetoactive Hydrogels to Probe Curvature‐Directed Endothelial Cell Mechanosensing

Advanced Healthcare Materials, EarlyView.
This work establishes a platform to investigate local curvature as a regulator of endothelial mechanosensing independent of shear stress. Magnetoactive hydrogels enable on‐demand curvature of endothelial monolayers to reproduce tortuosity quantified by clinically established metrics.
