Robots acting as macroscale analogs of active nanoparticles stop moving through friction alone, revealing a self-sustained cooling effect without external input. (Nanowerk News) How can a horde of ...

Using advanced microscopic techniques, researchers from labs around the world have shed light on the molecular basis of friction. Friction is a force that opposes motion when two materials slide over ...

The right kind of track can make the world of difference in your linear guide system. Optimize your application by learning all about linear guide track designs and alignment methods that you can use ...

Delving into history books, we can learn that already thousands of years ago the Egyptians realized that lubricants like water and oil helped reduce the friction of sledges that moved the heavy stones ...

An international interdisciplinary research team led by Prof. Richard GU Hongri, Assistant Professor of the Division of Integrative Systems and Design at The Hong Kong University of Science and ...

In science, friction is not automatically bad. Without friction, you have no traction: Wheels spin, and nothing moves. But with too much friction, you overheat, grind down parts, lose efficiency and ...

Friction is the force between two surfaces that are sliding, or trying to slide, across each other. For example, when you try to push a book along the floor, friction makes this difficult. Friction ...
