Nanoindentation of surfactant aggregates

Journal of Colloid and Interface Science, 2010
Surfactants are important for a wide range of applications dealing with one-dimensional nanoscale materials, including dispersion of carbon nanotubes, as organic templates in mesoporous silica thin films, and for the fabrication of silica nanowires. There is therefore great interest in better understanding the structure and properties of surfactant ...

A contact area function for Berkovich nanoindentation : Application to hardness determination of a TiHfCN thin film [PDF]

, 2014
In nanoindentation, especially at very low indenter displacements, the indenter/material contact area must be defined in the best possible way in order to accurately determine the mechanical properties of the material.
