You’re on the street and you’re alone. Spanning the horizon, you see the sun cresting and one glorious corner after another. Some are slow, others are fast, with a few nice straights in between. Tire ...

Irregularities present on a surface are often described as surface roughness or texture. These surface textures such as grooves and dimples impart friction, which is the force between two sliding ...

A research team led by Prof. Tian-Bao Ma from the Department of Mechanical Engineering at Tsinghua University has proposed a novel strategy to reduce friction and wear by inducing dynamic electronic ...

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 ...

1.1 What is friction? Take this everyday example: when a coffee mug rests on a flat table, the kinetic frictional force is zero. There is no force trying to move the mug across the table, so there is ...

A popular brand of angel hair pasta is helping researchers experimentally to understand the friction forces that occur in an earthquake fault and providing better information than current numerical ...

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 ...
