Acoustic tweezers are based on focused acoustic vortices and hold promise to precisely manipulate microorganisms and cells from the millimeter scale down to the submicron scale, without contact, and ...

Researchers are using ultrasonic waves to manipulate the viscosity of shear-thickening materials, turning solids to slush—and back again. The study, "Using Acoustic Perturbations to Dynamically Tune ...

Acoustic lenses are remarkable devices that just got cooler. A recent presentation at SIGGRAPH 2019 showed that with the help of 3D printing, it is possible to build the acoustic equivalent of optical ...

Researchers have demonstrated it's possible to silence noise using an open, ringlike structure, created to mathematically perfect specifications, for cutting out sounds while maintaining airflow.

A robotic system that uses ultrasound pulses to handle minuscule droplets of reagents has helped chemists to put a new reaction through its paces at lightning speed (ACS Cent. Sci. 2019, DOI: ...
