Facile Synthesis of a Carbon Nano Dot‐Based Wearable Flexible Thermoelectric Device

open access: yesAdvanced Materials Technologies, EarlyView.
A wearable proto‐type device made with low‐cost, bio‐friendly, and environmentally safe materials that can be readily fabricated to generate energy from low waste temperatures is demonstrated. The Carbon Nano Dot composite thin films are supported by a flexible cellulose substrate that harnesses thermoelectric principles to generate power from body ...

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

open access: yesAdvanced 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

open access: yesAdvanced 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.

Simultaneous Perfect Anomalous Reflection and Angle of Arrival Sensing in Reconfigurable Intelligent Surfaces

open access: yesAdvanced Optical Materials, EarlyView.
A reconfigurable intelligent surface is proposed that can simultaneously anomalously reflect the light and sense the angle of arrival. An in situ optimization of either the currents flowing on array elements or the far field in the receiver direction realizes anomalous reflection and suppresses parasitic scattering.

High Fidelity Waveguides Through Vitreous Media Recomposition for Next Generation Photonic Devices

open access: yesAdvanced Optical Materials, EarlyView.
A newly designed aluminosilicate glass enables the fabrication of femtosecond laser‐written optical waveguides with ultra‐low propagation losses of −0.020 dB cm−1 at 1310 nm and −0.037 dB cm−1 at 1550 nm. Raman, Brillouin, and electron microscopy analyses reveal the mechanisms behind refractive index modifications, highlighting the role of glass ...
