When placed in an acoustic field, small objects experience a net force that can be used to levitate the objects in air. In a new study, researchers have experimentally demonstrated the acoustic levitation of a 50-mm (2-inch) ...
(PhysOrg.com) -- As dough flies through the air, transforming from a ball into a disk in the chef’s experienced hands, pizza tossing can definitely be thought of as an art. But, as a recent study shows, pizza tossing is ...
(Phys.org) —A trio of researchers with the University of Tokyo in Japan has expanded the science of sound wave levitation by adding more speakers and controlling the focal point of the waves that are created. In so doing, ...
For the first time, a team of chemists and engineers at Penn State University have placed tiny synthetic motors inside live human cells, propelled them with ultrasonic waves and steered them magnetically. It's not exactly ...
