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) ...
(Phys.org)—There are many cool videos showing the Leidenfrost effect, which occurs when water droplets levitate and skid around on top of a very hot surface, rather than immediately evaporating like they do at temperatures ...
(Phys.org)—Magnetic levitation has been demonstrated for a variety of objects, from trains to frogs, but so far no one has developed a practical maglev-based actuator that converts some external source of energy into motion. ...
(Phys.org) -- Since the first demonstration of microelectromechanical systems (MEMS) in the mid-‘80s, the technology has not proven as useful as originally anticipated. One of the problems is that the tiny components ...
The levitation of microscopic objects in vacuum and the control of their movements while they are suspended was first demonstrated several decades ago. Since then, various research groups have been working on new approaches ...
Acoustic tractor beams use the power of sound to hold particles in mid-air, and unlike magnetic levitation, they can grab most solids or liquids. For the first time University of Bristol engineers have shown it is possible ...

(Phys.org)—A team of researchers with The University of Tokyo and Japan Synchrotron Radiation Research Institute has created a type of glass that is stronger than many metals. In their paper published in the journal Scientific ...
(Phys.org) —ETH researchers are able to make objects such as particles and liquid droplets fly in mid-air by letting them ride on acoustic waves. For the first time, they have been able to also control the movement of objects, ...

(Phys.org)—Japan intends to outdo itself, rendering the sleek bullet train system that won it fame in the 1960s toward becoming so "yesterday." You can now look forward to the upcoming marvels of floating trains. The country ...
(Phys.org)—The research, which is the first of its kind, has identified a specially engineered steel surface that allows liquids to boil without bubbling.
