Film‐Based Multi‐Photon Lithography for Efficient Printing of Electromagnetic Surface Structures

Advanced Materials Technologies, EarlyView.
This work introduces film‐based multi‐photon lithography as an efficient method for fabricating electromagnetic surface structures with 2D and 2.5D geometries, particularly THz and mid‐IR metasurfaces. These structures can be fabricated on various substrates, such as glass or silicon‐on‐insulator, over areas ranging from mm2 to cm2, achieving feature ...

Miniaturized Devices for On‐the‐Spot Generation of Small‐Diameter Vascular Grafts

Advanced Materials Technologies, EarlyView.
An intracorporeal extrusion device is developed for on‐the‐spot generation of vascular grafts with tunable diameters spanning from 1 to 6 mm. The device uses biomimetic polymers and light, to promptly obtaining biocompatible and high‐burst pressure‐resistant grafts.

Hybrid Electroluminescence Device for On‐Demand Single Photon Generation at Room Temperature

Advanced Optical Materials, EarlyView.
New type of electroluminescent device based on hBN nanocrystals deposited on a GaN laser diode displays electrically driven emission of single photons at room temperature. Low g2(0) autocorrelation function values are achieved of < 0.2 for continuous driving and < 0.4 for on‐demand single‐photon emission.
