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 ...

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, ...

Materials scientists are measuring the rolling friction of tiny, micrometer-sized particles. These measurements permit them to better understand everyday products such as concrete.

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 ...

The measuring tip of an atomic force microscope with a specially designed holder in which a spherical particle is “trapped”. The rights to the images always remain with the person referred to ...

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 ...

such as friction force microscopes, surface force apparatus or quartz microbalances, and the availability of advanced computational methods, which give access to nanoscale friction and wear phenomena.

From ketchup and paint to concrete and orange juice, many everyday materials are what scientists call suspensions—liquids ...

The measuring tip of an atomic force microscope with a specially designed ... a suitable measurement technique to measure the rolling friction occurring on the particle. Making a suitable holder ...
