Researchers have demonstrated how to entirely suppress static friction between two surfaces. This means that even a minuscule force suffices to set objects in motion. Especially in micromechanical ...

Say we consider a simple experiment of balancing a wooden rod on two fingers. The finger on the left, (1), will remain stationary, whereas the finger on the right, (2), will be moved toward the left.

Friction is an intrinsic physical phenomenon to curling. Without it, objects in motion would move endlessly, without slowing down. This would cause many safety-related problems: Cars or trains could ...

Schematic illustration of Friction Force Microscopy (FFM). The AFM cantilever, a small diving board-like structure about 200 micrometers long, 50 micrometers wide, and 1 micrometer thick, has a sharp ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

Nanomachines will depend on our knowledge of friction, heat transfer and energy dissipation at the atomic level for their very survival. In the scramble to revolutionize the world with nanotechnology ...

Friction at the atomic scale appears to depend on the speed at which two surfaces move past each other. This surprising behaviour was observed as the tip of an atomic force microscope (AFM) moves ...

THE author has already written an excellent book on geometrical statics, and it has been his present object to produce an elementary treatise which shall cover the well-trodden ground of the ...

An expert offers a primer on popular medical device coatings and their applications. Kevin Guenther A catheter with a lubricious coating. In the world of low friction, lubricious coatings for medical ...
