The range of materials that concrete contains scatters normal sound waves, making clear imaging difficult to obtain.

Researchers developed a high-resolution 3D ultrasonic imaging system for concrete, adapting to various structures for ...

Concrete structures like roads and bridges require nondestructive testing methods to identify interior defects without ...

Blood platelet aggregation with epinephrine (a) and low-frequency ultrasound (b) in vitro. In (b), two samples are sonicated with ultrasound at 60 W electric power (pink, red) and two samples are ...

When [Electron Impressions] used a powerful ultrasonic array to project a narrow beam of sound toward a target, he described ...

Researchers have discovered that a frog that lives near noisy springs in central China can tune its ears to different sound frequencies, much like the tuner on a radio can shift from one frequency to ...

Ultrasound—the technology used for sonograms and examining the heart—can increase the rate at which heart cells beat, researchers from Drexel University report. In their paper "Ultrasound-Induced ...
