| Zusammenfassung |
| We show that atomic force microscopy (AFM) phase images can reveal surface
features of soil dust particles, which are not evident using other
microscopic methods. The non-contact AFM method is able to resolve
topographical structures in the nanometer range as well as to uncover
repulsive atomic forces and attractive van der Waals' forces, and thus gives
insight to surface properties. Though the method does not allow quantitative
assignment in terms of chemical compound description, it clearly shows
deposits of distinguishable material on the surface. We apply this technique
to dust aerosol particles from the Sahara collected over the Atlantic Ocean
and describe micro-features on the surfaces of such particles. |
