Smeared Impedence Model for Variable Depth Liners [PDF]
Noise from modern aircraft engines has a significant broadband component, which has motivated the need for broadband acoustic engine liners. A promising broadband design, called a variable depth liner, is composed of groups of resonators tuned for ...

A Solution‐Based Deposition Method Enabling Pigment Blue Edible Electrochemical Transistors
A novel solution‐based method is presented to produce Copper Phthalocyanine fibrous films displaying effective ion permeability and enhanced transconductance in electrolyte‐gated transistors architectures. Using these films, the first instance of a fully edible electrolyte‐gated transistor with volumetric capacitance, targeting in‐body applications, is

Label‐Free 3D Photoacoustic Imaging of Tumor Organoids for Volumetric Drug Screening
A label‐free organoid photoacoustic imaging (LFOPI) system is developed for precise volumetric drug screening evaluation. As a proof of concept, LFOPI's performance in chemotherapy and immunotherapy drug screening assays are further evaluated. The LFOPI offers unique non‐invasive, label‐free capabilities for tumor organoids, and contributes to the ...
