Bridging tribological mechanisms at different scales.
A better microscopic understanding and control of friction guides the scientific focus of this Action, which addresses the following tasks:
- Drawing bridges between friction at different scales and properly relating the atomistic processes with the macroscopically observed effects.
- Controlling the tribological behaviour by imposing, e.g., tiny mechanical oscillations or by exploiting either natural surface geometries or externally induced interfacial nanostructures.
- Exploring confined interfaces under shearing. These tribological systems exhibit intriguing boundary lubricated regimes, whose tunability represents a priority for a variety of micromechanical devices where the early stages of motion and the stopping processes are often dominated by highly dissipative stick-slip dynamics.
- Understanding the diffusion, adhesion and friction mechanisms of atomic or molecular aggregates on surfaces. Single-cluster manipulation can serve as an ideal method to measure the interfacial friction of structurally well-defined contacts of controlled sizes and material pairings.
Scientific work plan methods and means
The scientific work plan is organized in four interrelated Working Groups (WGs), reflecting the four general themes sketched in this page.
Confined systems under shear.
Controlled nano movements.
The European groups, most of which have already expressed an interest in this Action, will carry out this work plan, keeping open possibilities for other groups to join the network during the course of the Action.
