New design lets micro-clock resonators ring like a bell

You can't hear most of them, but the world is running on different kinds of mechanical oscillations. For example, inside the average electronic wristwatch is a sealed canister containing a 3 mm long quartz crystal resonator. ...

Controlling acoustic transport in hypersonic crystals

Center for Nanoscale Materials users from Toyota Research Institute of North America, working with CNM's Nanophotonics Group, have determined that bulk coherent acoustic vibrations are heavily damped by scattering from radially ...

First step towards 'programmable materials'

Researchers from Empa and ETH Zurich have succeeded in producing a prototype of a vibration-damping material that could change the world of mechanics forever. The material of the future is not only able to damp vibrations ...

Explained: Phonons

For the engineers who design cell phones, solar panels and computer chips, it’s increasingly important to be able to control the way heat moves through the crystalline materials — such as silicon — that these devices ...

Taming the wild phonon

(PhysOrg.com) -- Researchers at MIT and elsewhere have succeeded in creating a synthetic crystal that can very effectively control the transmission of heat -- stopping it in its tracks and reflecting it back. This advance ...
