Ultrasonic scanner for radial and flat panels [PDF]
, 1973 An ultrasonic scanning mechanism is described that scans panels of honeycomb construction or with welded seams. It incorporates a device which by simple adjustment is adapted to scan either a flat panel or a radial panel.

Amyloidogenic Peptide Fragments Designed From Bacterial Collagen‐like Proteins Form Hydrogel
Advanced Functional Materials, EarlyView.This study identified amyloidogenic sequence motifs in bacterial collagen‐like proteins and exploited these to design peptides that self‐assemble into β‐sheet fibers and form hydrogels. One hydrogel supported healthy fibroblast growth, showing promise for biocompatible materials. Our work demonstrates that bacterial sequences can be harnessed to create

Advanced Functional Materials, EarlyView.We present a tissue‐stimulator platform for seamless electrode integration with pancreatic tissue, applying uniform electrical stimulation through optimized design with biohybrid 3D printing. Advantageous effects of electrical stimulation on β‐cell function were observed, including enhanced calcium signaling, islet morphology, and maturation.

Advanced Functional Materials, EarlyView.A hydrogel with dynamic cross‐links was formed by cross‐linking hyaluronic acid with curcumin‐preloaded, phenylboronic acid‐modified poly(amidoamine) dendrimers. This hydrogel exhibited excellent injectability and self‐healing ability, enabling controlled Cur release in response to low pH, high reactive oxygen species (ROS) generation, or mechanical ...

Assembly of Cell‐Seeded 3D Printed Hydrogel Modules with Perfusable Channel Networks
Advanced Functional Materials, EarlyView.Macroscale assembly was utilized to prepare perfusable tissue constructs from individually 3D printed hydrogel modules with embedded branched channel networks and port arrays for cell seeding. Novel multi‐material bioreactors were fabricated to facilitate the gluing of individual modules and the perfusion culture of assembled modular constructs seeded ...

INFLUENCE OF THE NORMAL FORCE ON THE SLIDING FRICTION UNDER ULTRASONIC OSCILLATIONS
Facta Universitatis. Series: Mechanical Engineering, 2015 The paper is devoted to an experimental investigation of the sliding friction force between a rapidly oscillating sample and a rotating steel plate. The sliding friction force is studied experimentally as a function of the oscillating amplitude, the ...
