(Nanowerk Spotlight) All mechanical systems exhibit vibrational resonances, where energy transmission through the structure spikes at certain natural frequencies. This resonance effect stems from the ...

In science and engineering, it's unusual for innovation to come in one fell swoop. It's more often a painstaking plod through which the extraordinary gradually becomes ordinary. But we may be at an ...

Damping vibrations is crucial for precision experiments, for example in astronomy. A new invention uses a special kind of magnets to achieve this -- electropermanent magnets. They consist of a ...

Hydrin-brand ECO has a long history of use in automotive applications due its exceptional heat and oil resistance up to 150°C, while maintaining flexibility at low temperatures down to -50°C. While ...

Vibration-absorbing, sound-damping materials such as sheets of rubber and expanded foam tend to be thick, bulky and soft. A new material is a big exception to that tendency, however, as it absorbs ...

A collaboration between the University at Buffalo School of Engineering and Applied Sciences and the U.S. Air Force Research Lab (AFRL) has shown it’s possible to electronically tune the frequency ...

Active or passive technology can be used to isolate vibrations from equipment. By employing active techniques, opposite but equal forces are created electronically via actuators and sensors to cancel ...
