The dynamic behaviors of the liquid marbles were monitored by a high-speed camera. Driven by the sound field, the liquid marbles moved toward each other, collided, and eventually coalesced into a ...

Levitation is something ripped straight out of science fiction, however one London-based start up has developed a device which can raise and manipulate small objects with sound ... Pressure Cage ...

And to know just how much fun those foilers are having ripping at full throttle out on the lake or sound. Urban Surf $350/two-hour lesson; 2100 N. Northlake Way, Seattle; 206-545-9463, urbansurf.com ...

Liquid marbles have promising applications in the field of microreactors, where the opening and closing of their surfaces plays a central role. We have levitated liquid water marbles using an acoustic ...

Method 2: Acoustic Levitation. Acoustic levitation involves using sound waves to generate enough pressure on an object that it counteracts the force of gravity. When sound waves interact with a solid ...

Imagine a high-speed train that travels through a tube at close to the speed of sound: What sounds like science fiction may soon become reality. It consists of a system of low-pressure tubes, through ...

In addition, as the sound pressure increases, the sound flow also affects the stability of the acoustic levitation. Comsol was used to nu-merical simulation the spatial sound field, pressure field and ...

But if you have 15 minutes to spare, there’s a better way to check noise exposure wherever you live, work or gather. Download this app. The NIOSH Sound Level Meter app for iOS, designed by the ...
