How long does a tuning fork ring? 'Quantum-mechanics' solve a very classical problem
Austrian and German researchers at the University of Vienna and Technische Universitaet Muenchen have solved a long-standing problem in the design of mechanical resonators: the numerical prediction of the ...
The sound in Saturn's rings: Physicists explain nonlinear dust acoustic waves in dusty plasmas
Dusty plasmas can be found in many places both in space and in the laboratory. Due to their special properties, dust acoustic waves can propagate inside these plasmas like sound waves in air, and can be studied with the naked ...
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.
Designing an acoustic diode
Most people know about ultrasound through its role in prenatal imaging: those grainy, grey outlines of junior constructed from reflected sound waves. A new technology called an "acoustic diode," envisioned ...
Radiation damage bigger problem in microelectronics than previously thought
The amount of structural damage that radiation causes in electronic materials at the atomic level may be at least ten times greater than previously thought.
Fantastic phonons: Blocking sound, channeling heat with 'unprecedented precision'
Imagine living on a bustling city block, but free from the noise of car horns and people on the street. The emerging field of phononics could one day make this a reality.
Acoustic tweezers can position tiny objects
(PhysOrg.com) -- Manipulating tiny objects like single cells or nanosized beads often requires relatively large, unwieldy equipment, but now a system that uses sound as a tiny tweezers can be small enough ...
Surfing on acoustic waves (w/ Video)
(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 ...
Scientists sweep cells apart for use in medical research
Scientists have developed a new method to separate cells, which could lead to more efficient medical research.
New metamaterials device focuses sound waves like a camera lens
(Phys.org) -- In a cover article in The Journal of Applied Physics, a team of Penn State researchers has designed and computationally tested a type of manmade metamaterial capable for the first time of man ...
Shifting sound to light may lead to better computer chips
By reversing a process that converts electrical signals into sounds heard out of a cell phone, researchers may have a new tool to enhance the way computer chips, LEDs and transistors are built.
Acoustic tweezers capture tiny creatures with ultrasound (w/ Video)
A device about the size of a dime can manipulate living materials such as blood cells and entire small organisms, using sound waves, according to a team of bioengineers and biochemists from Penn State.
Acoustic tweezers manipulate cell-to-cell contact
Sound waves can precisely position groups of cells for study without the danger of changing or damaging the cells, according to a team of Penn State researchers who are using surface acoustic waves to manipulate ...
Rap music powers rhythmic action of medical sensor
(PhysOrg.com) -- The driving bass rhythm of rap music can be harnessed to power a new type of miniature medical sensor designed to be implanted in the body.
