Researchers have created a new magnetically controlled capsule that can be ‘driven’ around the stomach using joysticks to take images of areas of interest. It's unlike other pill cams that rely on the ...

Certain areas of scientific research require atomically clean surfaces and low rates of contamination. In these instances, the ultra-high vacuum (UHV) environments are essential. There are a number of ...

Rolling-ring drives are friction drives that convert the constant rotary motion of a plain shaft into a traversing action that moves an attached carriage. Used in positioning and reciprocating ...

Big, innovative breakthroughs often result in game-changing technologies. Smaller incremental improvements in essential material components can similarly lead to significant performance and efficiency ...
