If you take two objects with fairly smooth surfaces, and put these together, you would not expect them to stick together. At least not without a liberal amount of adhesive, water or some other ...

The EC-SFA provides insights into the behavior of smooth and rough gold surfaces, the formation of oxide layers, and the dynamics of metal-ceramic contacts. (Image: Max Planck Institute for Iron ...

Earlier, we saw that the work done by friction on a particle sliding on a rough surface is negative, causing a loss in total mechanical energy as the particle slides. Here, we will address the ...
