In laboratories from Brazil to Munich, researchers are learning to grab matter with sound alone, sculpting ultrasonic waves ...

Alternatively, data from all transducers can be used while limiting the focal depth, allowing more transmit-receive pulses to ...

Osaka Metropolitan University researchers have solved a long-standing mystery in the field of sonochemistry: why do chemical reactions slow down when ultrasonic power becomes too strong? Active ...

Encapsulated microbubbles (EMBs), tiny gas-filled bubbles coated in lipid or protein shells, play a central role in ...

Acoustic waves encompass mechanical vibrations that propagate through diverse media, offering a robust means to characterise material properties from the nanoscale to the macroscale. Ultrasonic ...

Researchers have unraveled the phenomenon of a new 'third ultrasonic wave' being generated when two ultrasonic waves intersect within a plate. A research group led by Assistant Professor Yosuke Ishii ...

Most devices that use ultrasonic sounds to keep critters away don’t have a high rate of success. DEAR JOAN: We’re having a terrible problem with coyotes. My sister wants to try some kind of ultrasonic ...

Washington University Researchers have discovered that voice assistant programs like Siri can be hacked with ultrasonic sound waves that go undetected by human ears - but you probably won't have to ...

Using ultrasound waves propagating through a solid surface, researchers were able to read text messages and make fraudulent calls on a cellphone sitting on a desk up to 30 feet away. Ultrasonic waves ...

For years ultrasonics meant something only to dogs and other subhuman creatures. One of the few uses of ultra-high sound waves was in whistles, too high-pitched for human ears, to call pets. Today ...

Even in the cold darkness of winter, a hot muggy mosquito infested day sounds miserable. Thankfully, there’s now an air conditioner that doubles as a mosquito repellent. The repellent comes in the ...
