Sustainability has become a central theme in industries worldwide, and the cold rolling oils and lubricants market is no ...

Atoms slip against one another, eventually sticking in various combinations. Tectonic plates do the same, sliding across each ...

Soft spheres like these may be useful in space exploration, inspecting pipes or exploring cave systems. 28,921 people played the daily Crossword recently. Can you solve it faster than others?28,921 ...

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 ...

Rolling particles make suspensions more fluid Date: April 10, 2025 Source: ETH Zurich Summary: Materials scientists are measuring the rolling friction of tiny, micrometer-sized particles. These ...

What Purpose Does This Serve? The researchers could immediately calculate the coefficients for rolling and sliding friction of the various particles based on their data. These figures can be used in ...

The researchers were able to derive the coefficients for the rolling and sliding friction of the respective particles directly from their measurements. These figures can be used in computer models to ...

Superlubricity is a condition of near-zero friction between two moving, dry materials in contact with each other. Until now, superlubricious behavior has only been seen between super-small ...

Examples of Frictional Force: Walking: Friction between your shoes and the ground allows you to push off and move forward. Braking a car: Friction between the brake pads and the wheels slows down ...

At the Hannover Messe 2024, the Fraunhofer IST will be showing various demonstrators such as rolling bearing washers and gears applied with the thin-film multi-sensor described above.
