aCross-sectional dark-field scanning transmission electron microscopy imaging of a typical Pt/Co/MgO sample (the Co layer is 2.5 nm, the heavy Pt atoms appear to be brighter than the light Co atoms), indicating reasonably sharp Pt/Co and Co/MgO interfaces and negligible interfacial alloying ...
Critical damping; and Overdamping (heavy damping). In underdamped oscillations, the object comes to rest after a few oscillations with amplitude decreasing exponentially with time. Let's go back to the first oscillating object we have learned — a simple pendulum! It's an underdamped system. In...

However, conventional plastic feedstock would be unsuitable, since these tools need to be lightweight, strong enough to lift heavy parts, and durable enough to withstand thousands of cycles. This unique combination of properties is attainable by polymer-matrix composites, which also offer the ...
