Mechanical crystals, also known as phononic crystals, are materials that can control the propagation of vibrations or sound waves, just like photonic crystals control the flow of light. The ...

A spring-energized mechanical seal refers to the force used to maintain the seal face and the mating ring in close contact, which is supplied by a mechanical spring device. This device can be a wave ...

Stanford University researchers have developed a key experimental device for future quantum physics-based technologies that borrows a page from current, everyday mechanical devices. Reliable, compact, ...
