| Abstract Scope |
Novel nanostructured materials – especially those exploiting high specific surface area and size effects via unconventional structural geometry - go beyond functions predicted by conventional models of mechanical response. Yet to discern these unique functionalities, nanomechanical approaches are needed. In this presentation we consider the influence of electrochemical potential on the mechanical response of nanoporous materials by using a modified electrochemical cell coupled to a nanoindenter. Comparison to results from macro-mechanical testing methods point to the unique role micromechanical testing plays in identifying fundamental relations between microstructural characteristics and the functional response of materials. Examples of such materials including nanoporous gold and nanoporous Si will be presented in terms of the influence of length-scale, structural geometry and electrochemical potential on the mechanical response. |
