Advanced Materials, EarlyView.This study demonstrates a self‐assembly process to generate free‐standing piezoelectric nanomembranes, forming ultracompact microtubular acoustic wave sensors and actuators. The miniaturized 3D piezoelectric platform reported in this work can be applied in telecommunication, energy harvesting, and acoustofluidics. Moreover, the 3D self‐assembly can add

Advanced Materials Technologies, EarlyView.This study explores how machine learning models, trained on small experimental datasets obtained via Phase Doppler Anemometry (PDA), can accurately predict droplet size (D32) in ultrasonic spray coating (USSC). By capturing the influence of ink complexity (solvent, polymer, nanoparticles), power, and flow rate, the model enables precise droplet control

Volumetric microvascular imaging of human retina using optical coherence tomography with a novel motion contrast technique [PDF]
, 2009 Phase variance-based motion contrast imaging is demonstrated using a spectral domain optical coherence tomography system for the in vivo human retina. This contrast technique spatially identifies locations of motion within the retina primarily associated

Group Delay Dispersion Measurements on Mid‐Infrared Supermirrors
Advanced Optical Materials, EarlyView.Group delay dispersion of novel semiconductor‐based optics is measured in the mid‐infrared spectral range (2.5 to 4.8 μm$\rm \umu{\rm m}$). Comparisons are made between simulations, measurements conducted with a home‐built white light interferometer, and measurements performed with a commercially available FTIR.

The Journal of Tepecik Education and Research Hospital, 1992 Color Doppler instruments provide gray-scale imaging with two-dimensional flow in real time. Velocity information is encoded in color. Color Doppler imaging parameters, including packet size, color gate, color gain, color reject, capture function, velocity map, and velocity tag, are described.
