Researchers have demonstrated how to entirely suppress static friction between two surfaces. This means that even a minuscule force suffices to set objects in motion. Especially in micromechanical ...

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 ...

For the first time, physicists in China have virtually eliminated the friction felt between two surfaces at scales visible to the naked eye. In demonstrating "structural superlubricity," the team, led ...

Friction is created when two surfaces slide one on top of the other. Since this consumes additional energy, this so-called sliding friction is considered an irksome yet inevitable aspect of dynamic ...

Friction is defined as the resistance to relative motion between two bodies of contact. The force of friction is independent of the area of surfaces in contact and is directly proportional to the ...

(Nanowerk News) Mechanical systems in which moving parts come into regular contact are prone to damage due to the effects of friction. Researchers at Tohoku University have developed a contact control ...

Researchers have discovered for the first time, through theoretical calculation and experiment that macroscopic frictions occurring between clay mineral surfaces originate from interatomic ...

Friction is an intrinsic physical phenomenon to curling. Without it, objects in motion would move endlessly, without slowing down. This would cause many safety-related problems: Cars or trains could ...

Whether water acts as a lubricant or not depends on the nature of the two surfaces. For water to reduce friction, it must reduce the contact area between two surfaces by separating them and acting as ...
