Acoustic tweezers device expands the range of X-ray crystallography
A device for precisely positioning small objects using acoustic waves has now been used to position fragile protein crystals a few micrometers or less in size in the path of a crystallography X-ray beam. ...
Study examines role of acoustic-gravity waves as ocean transport, early warning of tsunamis
Acoustic-gravity waves—a special type of sound wave that can cut through the deep ocean at the speed of sound—can be generated by underwater earthquakes, explosions, and landslides, as well as by surface ...
Acoustic levitation made simple
A team of researchers at the University of São Paulo in Brazil has developed a new levitation device that can hover a tiny object with more control than any instrument that has come before.
