Enhanced Two‐Photon Excited Emission of Quantum Emitters by Colloidal Plasmonic Metasurfaces

Advanced Photonics Research, EarlyView.
Colloidal plasmonic metasurfaces presenting a completely exposed optical cavity are fabricated via templated self‐assembling silver nanoparticles into squared arrays on top of a thin film of CdSe/ZnS quantum dots. The resulting structure promotes the enhancement of the two‐photon absorption and emission processes of the quantum emitter by exploiting ...

Fully Printed Variable Orifice Flowmeter with Built‐In Temperature Compensation for Application in Mechanical Ventilation

Advanced Sensor Research, EarlyView.
Additive manufacturing, specifically fused deposition modeling, offers an innovative approach to creating 3D‐printed variable orifice flowmeters with integrated temperature compensation. Using carbon‐black TPU, the primary component (a variable orifice) and the secondary element (a diaphragm pressure sensor) are fabricated.
