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 ...

Although humans have been harnessing its power since rubbing two sticks together to build the first fire, the physics of friction remain largely in the dark. Now, Brandeis research is showing that ...

Atomic force microscopy (AFM) is a powerful technique that enables ... quantifies single polymer chain elongation, and assesses the friction of single polymers on surfaces. In pharmaceutical research, ...

For example, measurements of the force required to drag the aluminium tip of a scanning tunnelling microscope over a gold surface estimate a friction force, linear in velocity, of the order of 10 ...

One of the most important acronyms in nanotechnology is AFM – Atomic Force Microscopy. This instrument has become ... chemical potentials, friction and so on), and also to perform various types of ...

In the past twenty years, powerful tools such as atomic force microscopy have made it possible to accurately investigate the phenomena of friction and wear, down to the nanometer scale. Readers of ...
