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 ...

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 ...

Superlubricity offers potential for dramatically reducing friction, potentially decreasing energy consumption in various applications. The phenomenon is characterized by extremely low friction levels ...

Nanotribology is the study of friction, wear, and lubrication at the nanoscale. It focuses on understanding and controlling the interactions between surfaces in relative motion when the contact area ...

A recent article published in Advanced Functional Materials investigated the friction behavior of surfaces coated with surface-attached hydrogel layers. These natural synovial-joint structure-inspired ...

A technical paper titled “Dynamically tuning friction at the graphene interface using the field effect” was published by researchers at University of Illinois Urbana-Champaign and University of ...

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 ...
