High Aspect Ratio, Superconducting Vacuum Gap Capacitor NEMS with Plate Distances Down to 32 nm
Fabrication of aluminium vacuum gap capacitor based NEMS is investigated with a free to move top electrode. To avoid collapse of the top electrode vertical stress gradient is controlled through sputter parameters. The result is wafer‐level high‐yield fabrication of vacuum gap capacitors with radii between 7 µm and 30 µm and integrated piezoactuators. A

Optimizing Metamaterial Inverse Design with 3D Conditional Diffusion Model and Data Augmentation
A generative AI model, the 3D conditional diffusion model (3D‐CDM), is introduced to enhance the inverse design of voxel‐based metamaterials. A data augmentation technique based on topological perturbation expands the dataset, further improving generation quality and accuracy.

Development of a Miniaturized Capillary Rheometer for High Shear Rate Rheology of Dense Suspensions
This research presents a downscaled benchtop, low‐cost capillary rheometer that can characterize high shear rate rheometry of dense suspensions. The device is capable of measuring across a wide range of applicable shear rates using only a limited quantity of material and addresses a need for an accurate and affordable capillary rheometer.

By combining static and time‐resolved optical, structural, and rheological techniques, we demonstrate that the blue‐shift upon solidification of ethyl cellulose‐acrylic acid mesophases corresponds to the reorientation of cholesteric domains. Modulating the mesophase chain mobility and photopolymerization reaction kinetics enables solid chiral nematic ...

Thermal‐Energy‐Boosted Luminescence for Precise Optical Thermometry in Eu/Tb‐Doped ScNbO4
This paper presents a novel phosphor for high‐performance optical thermometry utilizing thermal‐energy‐assisted luminescence boosting. The samples are prepared by incorporating Eu‐doped ScNbO4 and Tb‐doped ScNbO4 powders into a PDMS matrix. Under blue light excitation, the sample exhibits a stunning emission color change from green to red as the ...

High‐Isolation LCoS‐Based Optical Switch with Phase Hologram Parameter Optimization
A 1 × 9 liquid crystal on silicon (LCoS)‐based optical switch is experimentally demonstrated, revealing that the worst‐case port isolation exceeds 37 dB within the wavelength range of 1460–1540 nm. This work offers an alternative route for the development of optical switches with a large number of ports and high isolation, applicable to large‐capacity ...
