In Situ Two‐Dimensional Residual Stress Characterization of Thin Films
Advanced Materials Technologies, EarlyView.An integrated in situ curvature metrology platform combining speckle‐based curvature optical metrology (SCOM) with multi‐beam optical sensors (MOS) enables spatially resolved two‐dimensional curvature mapping of thick sputtered coatings. The SCOM technique provides excellent agreement with MOS while providing an extended measurable curvature range ...

High Throughput Aerosol Jet Printing to Operationalize High Aspect Ratio Patterning
Advanced Materials Technologies, EarlyView.High‐throughput aerosol jet printing poses distinct limiting mechanisms to the printing process. These include rapidly changing ink chemistries, atomization instabilities, and liquid‐phase spreading. The combination of in‐line heating, process monitoring, and traditional optimization procedures enables rapid printing of high‐aspect‐ratio structures ...

Exploring Molecular Pathways in Refractive Errors Associated with Inherited Retinal Dystrophies
Frontiers in Bioscience-LandmarkThe term inherited retinal dystrophies (IRDs) refers to a diverse range of conditions characterized by retinal dysfunction, and mostly deterioration, leading to a gradual decay of the visual function and eventually to total vision loss.

Advanced Optical Materials, EarlyView.Comparing Fabry–Perot and plasmonic nanorod cavities reveals how the number of dark states dictates polariton relaxation. The high number of dark states results in a polaritonic bottleneck, while reducing the number of dark states enables to measure the polaritonic decay.
