ETH Zurich scientists measure rolling friction in micrometer-sized particles, enhancing understanding of suspensions in ...

Materials scientists are measuring the rolling friction of tiny, micrometer-sized particles. These measurements permit them to better understand everyday products such as concrete.

Join Alemnis' three-day course on tribology to master friction, wear, and lubrication, enhancing the reliability of mechanical systems with cutting-edge techniques.

From ketchup and paint to concrete and orange juice, many everyday materials are what scientists call suspensions—liquids ...

When two surfaces are in contact ... suspected that there is no static friction coefficient, but now we have conclusively proven this by using optical micro-measurements of unprecedented accuracy ...

Although humans have been harnessing its power since rubbing two sticks together to build the first fire, the physics of friction remain largely in the dark. Now, Brandeis research is showing that ...

Suspensions are widespread in industry and everyday life. By a suspension, materials scientists mean a liquid in which tiny, ...

ETH Zurich Materials Scientists are the first to measure the microscopic forces involved when particles ... The researchers derived friction coefficients from the measurements, which are now being ...
