Static friction might be an illusion made by the rotation of kinetic friction, even though, since the time of Charles-Augustin de Coulomb (1736–1806), we have believed that there exist two types of solid friction. Nakano […]

Let’s say you have the choice between an almost infinite lifespan device, and a device that undergoes wear and failure within a few minutes or hours of running. In most cases, you would choose the […]

Friction is a force rising between two surfaces when they move in opposite directions or when one moves over a stationary surface. The scale of the movement does not matter: from the movement of continental […]

With the last years’ rise of electric vehicles (EV), you may have thought that the future lubrication challenges for cars may not be challenging anymore. At least not as challenging as the ones that the […]

Friction is the force experienced when two surfaces slide, or try to slide, across each other. We are thankful for friction when we put our foot on the brake to stop the car, or when […]

The history of science sometimes reads like a detective novel. The personal destinies sometimes lead to the fact that outstanding, ingenious works which were decades ahead of their time, sink into oblivion. This seems to […]

The earth seems to be fairly solid as we stand on its surface. We stand on solid ground and do not sink through the floors in our homes. However, underneath that solid-looking crust are layers […]

Recent research (https://doi.org/10.1007/s40544-017-0183-5) has shown that about 23% of the world’s total energy consumption comes from the tribological contacts (moving parts subject to friction and wear, such as bearings, gears, etc.). This energy is lost, […]
